Structural Features Of Hydraulic Horizontal Broaching Machine:
Structural characteristics of hydraulic horizontal broaching machine:
(1): Because the broaching process only involves primary motion (broaching tool movement) and no feed motion (completed by the tooth lift of the broaching tool itself), the machine tool (broaching machine) is basic in structure:
(2): The broach is a multi-edged tool that can rough and finish in one stroke, resulting in great production. In bulk or batch manufacturing, the cost is cheaper, especially when processing a large number of holes or exterior surfaces with specific forms, and the efficiency is greater:
(3): Because of the low broaching speed, the hydraulic horizontal broaching machine’s broaching operation is smooth, and the thickness of the cutting layer is very thin, machining precision may approach h7 level and roughness can be as low as ra0.8 micron. A floating extrusion ring added at the end of the broach can further minimize roughness. The hydraulic horizontal broaching machine can reach a roughness of around 0.2 microns.
(4)): The technical and competency requirements for operators are generally low.
(5): Processing costs are cheap. Although the broach is pricey, it has a lengthy lifespan. A broach may process a large number of workpieces simultaneously. Processing productivity is excellent, resulting in cheaper broaching costs.

Maintenance Of Hydraulic Horizontal Broaching Machine
The proper usage and upkeep of equipment is an essential component of equipment management. Operators and specialists perform a series of maintenance tasks on the equipment based on its technical data, parameter needs, and maintenance details. It is also an objective necessity for moving the equipment itself.
1.Lubricate and maintain the machine according to its lubricating needs.
2.After each year of operation, the hydraulic oil should be removed from the bed tank, cleaned, and replaced with filtered hydraulic oil. The oil volume should be calculated as 3/4 of the height of the oil mark.
3.The oil filter net in the oil suction pipe should be cleaned or washed on a regular basis.
4.Regularly inspect the handle, knobs, and buttons for damage.
5.The motor should be kept clean, and the air input grille should be adequately ventilated and not clogged.
6.Lubricate and clean the machine tool 10 minutes before leaving work each day.
7.Non-operators are absolutely banned from using the equipment, and the machinery must be stopped when individuals exit the machine.
Lubrication Method Of Hydraulic Broaching Machine And Repair Method Of Grinding Damage
Broaching machines have numerous and complicated lubrication sites, and many hydraulic broaching machines are lubricated simultaneously, including:
- Manual lubrication: Apply lubricating oil or grease to the friction surfaces by hand.
- Oil dripping lubrication: Lubricating oil drops into the friction portion due to its weight (often utilizing a needle valve leaking oil cup).
- Oil rope lubrication: Use the capillary action of an oil rope submerged in oil or the negative pressure created by the rotating shaft for self-priming lubrication, for example.
- Oil pad lubrication: Self-priming lubrication relies on the capillary action of an oil pad soaked in oil or the negative pressure created by the spinning shaft.
- Self-priming lubrication: Self-priming lubrication involves immersing in the negative pressure created by the revolving shaft.
- Centrifugal lubrication: Due to centrifugal force, lubricating oil flows constantly down the conical surface to the lubrication point.
- Oil bath lubrication: The friction surface is partially or completely submerged in lubricating oil and then operated.
- Oil ring lubrication: The spinning components pass through the oil pool, and oil is brought or splattered onto the lubricated sections.
- Splash lubrication: The rotating parts pass through the oil pool, and the oil is delivered or sprayed onto the lubrication component.
- Scraper lubrication: The spinning parts pass through the oil pool, and the oil is transported or splattered onto the lubrication component.
