Both configurations drive a multi-tooth broach through or across the workpiece in a single linear stroke, and both cut the same forms \u2014 keyways, splines, hexagons, flats, and contours. The cutting physics are identical. What separates the two machines is everything around the cut: how much floor they occupy, how long a stroke they can deliver, how chips leave the work zone, how parts load and unload, and how each fits into a production line.<\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_87_1 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<div class=\"ez-toc-title\" style=\"cursor:inherit\">Indice dei contenuti<\/div>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Allinea la tabella dei contenuti\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewbox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewbox=\"0 0 24 24\" version=\"1.2\" baseprofile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/broachingmach.com\/it\/difference-between-horizontal-and-vertical-broaching-machine\/#What_Is_a_Horizontal_Broaching_Machine\" >What Is a Horizontal Broaching Machine?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/broachingmach.com\/it\/difference-between-horizontal-and-vertical-broaching-machine\/#What_Is_a_Vertical_Broaching_Machine\" >What Is a Vertical Broaching Machine?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/broachingmach.com\/it\/difference-between-horizontal-and-vertical-broaching-machine\/#Horizontal_vs_Vertical_Broaching_7_Differences_That_Drive_the_Decision\" >Horizontal vs. Vertical Broaching: 7 Differences That Drive the Decision<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/broachingmach.com\/it\/difference-between-horizontal-and-vertical-broaching-machine\/#1_Stroke_Direction_and_Machine_Structure\" >1.

The workpiece is fixtured stationary at working height, and the ram \u2014 running on precision ways along the bed \u2014 pulls or pushes the broach through the part in one horizontal pass. Most horizontal machines are pull-type internal machines, because a broach in tension cannot buckle, but the same bed-and-ram architecture also serves surface broaching and continuous chain broaching, where fixtured parts ride past stationary broaches without stopping.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Two structural facts define the category. The bed extends along the floor, so stroke capability grows outward rather than upward. And the work zone stays open at both ends and from above, so heavy parts reach the fixture with the cranes, hoists, and roller conveyors that most shops already own. If you are new to the process itself, start with our primer on <a href=\"https:\/\/broachingmach.com\/it\/what-is-broaching\/\">cos\u2019\u00e8 la brocciatura<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_a_Vertical_Broaching_Machine\"><\/span>What Is a Vertical Broaching Machine?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For the basics of each configuration, see <a href=\"https:\/\/broachingmach.com\/it\/what-is-horizontal-broaching\/\">what horizontal broaching is<\/a> e <a href=\"https:\/\/broachingmach.com\/it\/what-is-vertical-broaching\/\">what vertical broaching is<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <a href=\"https:\/\/broachingmach.com\/it\/vertical-broaching-machine\/\">vertical broaching machine<\/a> carries its ram on an upright column, so the broach travels vertically \u2014 either pulled down through the part from an upper slide or pulled up through it from below. The machine grows upward instead of outward, which is why a vertical machine delivers a long stroke inside a compact footprint. Internal work dominates (keyways, splines, hex sockets, polygon bores), and the main configurations \u2014 <a href=\"https:\/\/broachingmach.com\/it\/pull-up-vs-pull-down-broaching\/\">pull-up, pull-down, and push-type<\/a> \u2014 differ mainly in where the part sits and which direction gravity acts on the chips. Surface work happens on vertical surface machines as well; see our <a href=\"https:\/\/broachingmach.com\/it\/surface-broaching-machine-guide\/\">Guida alla macchina per la brocciatura piana<\/a> for that family.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vertical machines own the middle of the part-size range and the top of the volume range. Typical work includes internal splines and keyways in transmission gears, hexagon and square sockets in fittings and hand tools, bore forms in wheel hubs and brake components, and exterior flats and slots on small castings and forgings \u2014 parts measured in hundreds of grams to a few dozen kilograms, produced in thousands per shift, often fed by automation rather than an operator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The classic horizontal workload is large and long: internal splines and keyways in gears, sprockets, and pump housings; bore and face work on cylinder blocks and heads; deep features in tubes and barrels; and exterior flats, slots, and dovetails on chassis castings. High-volume small parts \u2014 lever forks, link ends, pads \u2014 also land here when they feed a continuous chain machine, where the broaches stand still and the parts ride past.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Horizontal_vs_Vertical_Broaching_7_Differences_That_Drive_the_Decision\"><\/span>Horizontal vs. Vertical Broaching: 7 Differences That Drive the Decision<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The table below summarizes the seven factors; the sections after it explain the engineering reason behind each difference, because the &#8220;why&#8221; is usually what settles the argument on a specific part.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Factor<\/th><th>Horizontal machine<\/th><th>Vertical machine<\/th><\/tr><\/thead><tbody><tr><td>Stroke direction<\/td><td>Ram travels level along a floor bed<\/td><td>Ram travels up or down an upright column<\/td><\/tr><tr><td>Floor space and installation<\/td><td>Long, low footprint; no pit, no special ceiling<\/td><td>Compact footprint; stroke is bounded by building height or pit depth<\/td><\/tr><tr><td>Stroke length ceiling<\/td><td>Practically unlimited \u2014 beds extend to carry multi-meter broaches<\/td><td>Long broaches get awkward to hang and support<\/td><\/tr><tr><td>Chip and coolant flow<\/td><td>Chips travel along the bed; flushing must be engineered<\/td><td>Gravity pulls chips and coolant down and out of the cut continuously<\/td><\/tr><tr><td>Workpiece handling<\/td><td>Heavy parts load from above at working height with cranes or rollers<\/td><td>Parts load onto a fixture table; small and mid-size parts are natural, very heavy parts need lift planning<\/td><\/tr><tr><td>Automation pattern<\/td><td>In-line flow: conveyor in, cut, conveyor out<\/td><td>Turret and shuttle patterns: load, broach, and unload in overlapping time<\/td><\/tr><tr><td>Cost profile<\/td><td>Generally lower purchase price; larger footprint and lower tooling cost<\/td><td>Higher entry price for servo and twin-ram designs; saves floor and often wins on cost per part at volume<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"1_Stroke_Direction_and_Machine_Structure\"><\/span>1. Stroke Direction and Machine Structure<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The fundamental difference is geometric: a horizontal machine lays its stroke along the floor, a vertical machine stands it upright. Everything else follows from that choice. On a horizontal machine, the broach lies along its full length on the bed, supported and guided, and the part rests on level locators with cutting force pressing it into its seat. On a vertical machine, the broach hangs from or rises toward the slide, and the part sits on a table or fixture face directly in the tool path. Neither layout cuts better \u2014 they cut differently, and the part decides which geometry is convenient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Floor_Space_and_Installation\"><\/span>2. Floor Space and Installation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A horizontal machine trades height for length. The bed scales with stroke and broach length, so the machine occupies a long rectangle of floor \u2014 but it installs directly on a standard slab, needs no pit, and stays within ordinary ceiling height. A vertical machine makes the opposite trade: it occupies a compact footprint that fits inside a small cell, but its stroke is bounded by the building. Some pull-down and table-up designs need an overhead clearance allowance or a floor pit to gain stroke, which means foundation work and a machine that is harder to relocate later. If your building has low bays, the horizontal layout sidesteps the problem entirely; if floor space is the scarce resource, vertical wins on the same stroke.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Stroke_Length_Capability\"><\/span>3. Stroke Length Capability<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Why can horizontal machines run longer strokes? Because the bed extends along the floor, adding stroke means adding bed length \u2014 there is no practical ceiling. A long internal spline or deep keyway demands a long broach, and a long broach is a heavy, slender precision tool. Hung vertically, its own weight works against the guidance and support it needs; laid horizontally, the full length of the tool rests on the bed&#8217;s support rollers and ways. This is why deep bores in tubes and barrels, and splines running the length of a shaft, are almost always cut horizontally. On a vertical machine, the stroke you can buy is the stroke your building can stand \u2014 plus pit depth if you are willing to dig one.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Chip_Removal_and_Coolant_Handling\"><\/span>4. Chip Removal and Coolant Handling<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Vertical machines hold a structural advantage here, and the reason is gravity. As the broach cuts downward, chips and coolant fall away from the cutting zone continuously \u2014 flushed from above, they drain below, keeping finished teeth clear of debris and the part clean. On a horizontal machine, chips exit the cut at the same height they are created and travel along the bed, so the machine depends on engineered flushing, sloped beds, or chip conveyors to move them. Why does this matter enough to swing a decision? Recut chips trapped in the work zone score the finished surface and accelerate tooth wear, so difficult, stringy materials raise the premium on the vertical layout&#8217;s natural cleanliness.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Workpiece_Size_Shape_and_Handling\"><\/span>5. Workpiece Size, Shape, and Handling<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Match the machine to the part&#8217;s natural resting posture. Large, heavy, flat-backed workpieces \u2014 steering knuckles, control arms, cylinder blocks, large valve bodies \u2014 are awkward to stage upright but lie naturally on horizontal locators, and overhead cranes or rollers deliver them from the direction heavy parts prefer to move. Vertical machines favor parts that sit stable on a fixture table: gears, sprockets, hubs, pulleys, and components with large diameters and short lengths, as well as small high-volume parts like lever forks and fittings. A general rule that holds well: if the part needs a crane, think horizontal; if it fits in two hands or a chute, vertical loading is faster and less fatiguing for the operator.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Automation_and_Line_Integration\"><\/span>6. Automation and Line Integration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The two layouts automate in different patterns, and the pattern usually follows the plant&#8217;s material flow. Horizontal machines suit in-line integration: parts arrive on a conveyor at fixed height, get broached, and leave in a straight line \u2014 the native rhythm of automotive transfer lines. Vertical machines suit overlapping cycles: rotary indexing tables and shuttle systems let one station load while another cuts, and pull-up machines place the loading station low, exactly where bowl feeders and pick-and-place units want to work. Twin-slide vertical machines take this further, cutting two features or two parts in alternating strokes. Neither approach is inherently more productive; the question is which one matches the line the machine must join.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Machine_Cost_and_Tooling_Cost\"><\/span>7. Machine Cost and Tooling Cost<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Horizontal machines are generally the lower-ticket entry: the structure is simpler, the installation is a standard slab, and retooling between jobs is quick, which keeps tooling-related cost down when volumes are modest or part variety is high. Vertical machines \u2014 particularly servo-driven and twin-ram designs \u2014 carry a higher purchase price, but they repay it where floor space is expensive and volumes are high, because the compact footprint and faster automated cycles push cost per part down. One rule worth more than the price tags: if you already own a library of broaches from a horizontal machine, staying horizontal lets that inventory keep working. For a fuller breakdown of what each configuration costs to buy and run, see our <a href=\"https:\/\/broachingmach.com\/it\/broaching-machine-price-guide\/\">Guida ai prezzi delle macchine per brocciatura<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Choose_A_Four-Question_Decision_Framework\"><\/span>How to Choose: A Four-Question Decision Framework<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Set the spec sheets aside for a moment and answer four questions about your own production. Each answer points at one layout, and when the answers disagree, weight them in this order.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Question_1_What_does_the_workpiece_look_like\"><\/span>Question 1: What does the workpiece look like?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Weigh the part and picture its resting posture. Parts over roughly 50 kg, or long parts with features along their length, load and locate better lying flat \u2014 horizontal. Small and mid-size parts with internal features, and disc-shaped parts with large diameters and short lengths, load faster onto a vertical fixture table \u2014 vertical. This first question eliminates more options than any spec comparison.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Question_2_How_much_stroke_does_the_feature_need\"><\/span>Question 2: How much stroke does the feature need?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Remember that stroke length is not the same as cut length: the ram must pull the entire broach clear of the work. Add the broach length, the part length, and clearances, then compare the total against your building&#8217;s vertical budget. When the required stroke exceeds what your ceiling (plus any pit you are willing to excavate) can offer, the decision is made for you \u2014 horizontal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Question_3_What_does_your_floor_space_and_building_allow\"><\/span>Question 3: What does your floor space and building allow?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Measure the actual footprint available, not the one on the drawing. A long horizontal bed competes with aisles and adjacent cells; a tall vertical machine competes with cranes, mezzanines, and overhead utilities. Also check the foundation: a pit or special anchoring adds cost and permanence to a vertical installation, while a horizontal machine bolts to a standard slab and can move with the layout.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Question_4_How_will_parts_load_unload_and_flow\"><\/span>Question 4: How will parts load, unload, and flow?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sketch the part&#8217;s journey through the cell. If parts move on a conveyor line at fixed height \u2014 in-line flow \u2014 a horizontal machine accepts and releases them without a lift. If you want overlapping load-and-cut cycles, indexing tables, or feeder-fed small parts, the vertical layout is built for it. And if volumes are still uncertain, favor the machine that retools cheaply: that is usually the horizontal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a deeper walk through this decision \u2014 tonnage, drive types, tolerance capability, and new-versus-used tradeoffs \u2014 see our dedicated article on <a href=\"https:\/\/broachingmach.com\/it\/how-to-choose-the-right-broaching-machine\/\">how to choose the right broaching machine<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Quick_Reference_Where_Common_Parts_Usually_Land\"><\/span>Quick Reference: Where Common Parts Usually Land<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A shortcut built from shop-floor practice \u2014 useful for a first cut at the decision before the four questions above are asked in earnest:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Transmission gears, sprockets, pulleys, wheel hubs<\/strong> \u2014 internal splines and keyways in mid-size parts: vertical, usually pull-down.<\/li>\n\n\n\n<li><strong>Fittings, hex sockets, hand-tool components<\/strong> \u2014 small parts at high volume: vertical pull-up, feeder-fed.<\/li>\n\n\n\n<li><strong>Steering knuckles, control arms, crossmembers<\/strong> \u2014 heavy castings with exterior surfaces: horizontal surface machines.<\/li>\n\n\n\n<li><strong>Cylinder blocks and heads<\/strong> \u2014 large castings, multiple features: horizontal, in-line with the machining line.<\/li>\n\n\n\n<li><strong>Long shafts, tubes, barrel bores<\/strong> \u2014 deep features along the length: horizontal internal machines; no practical vertical alternative.<\/li>\n\n\n\n<li><strong>Lever forks, link ends, pads in very high volume<\/strong> \u2014 small external features: horizontal continuous chain machines.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Treat the list as a starting point, not a verdict \u2014 tolerances, materials, and volumes can move a part from one column to the other. When two of the four questions above point the same way, that is your machine.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Domande frequenti<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_the_difference_between_horizontal_and_vertical_broaching\"><\/span>What is the difference between horizontal and vertical broaching?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The difference is the direction of the cutting stroke. A horizontal broaching machine drives the broach along a level bed, parallel to the floor; a vertical broaching machine drives it up or down an upright column. The cut quality is comparable in both layouts \u2014 the real consequences are practical: horizontal machines offer longer strokes and easier handling of heavy parts, while vertical machines offer a compact footprint, gravity-assisted chip removal, and automation-friendly loading stations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Which_is_better_horizontal_or_vertical_broaching\"><\/span>Which is better, horizontal or vertical broaching?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Neither is better overall \u2014 each wins on specific work. Choose horizontal for long strokes (deep splines, long keyways), large heavy workpieces that load from above, and in-line conveyor flow. Choose vertical for small and mid-size parts, tight floor space, stringent cleanliness needs in difficult materials, and overlapping-cycle automation. Many plants run both, each assigned to the parts it handles best.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_are_most_broaching_machines_vertical\"><\/span>Why are most broaching machines vertical?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Because the vertical layout solves three everyday production problems at once. It grows upward, so it delivers a useful stroke in a compact footprint. Gravity pulls chips and coolant out of the cut, keeping tools and parts clean without elaborate flushing. And parts load at a convenient station height, which suits both operators and automated feeders. For the majority of parts \u2014 gears, hubs, fittings, and similar small-to-mid-size work \u2014 those advantages compound, which is why vertical machines outnumber horizontal ones on most shop floors.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_a_linear_broaching_machine\"><\/span>What is a linear broaching machine?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A linear broaching machine is any machine that cuts by moving a multi-tooth broach in a straight line through or across the workpiece, completing the feature in one pass. Both horizontal and vertical broaching machines are linear broaching machines \u2014 the label describes the straight-line cutting motion, not the machine&#8217;s orientation. The alternative is rotary broaching, which spins and wobbles a form tool into the part on a lathe or screw machine to cut a polygon on center. Linear machines handle the long-form work rotary broaching cannot: keyways, splines, and profiles with depth.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Bottom_Line\"><\/span>The Bottom Line<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Horizontal and vertical broaching machines are not competitors \u2014 they are the same process pointed in two directions. Let the workpiece make the call: heavy and long parts with deep features belong on the horizontal bed; compact parts, tight floors, and automated cells belong on the vertical column. When the answers conflict, weight the part first, stroke second, floor third, and flow fourth.
