maquinagem que remove material utilizando uma ferramenta dentada conhecida como brocha. Existem duas formas principais de brochagem: linear e rotativa. O procedimento mais t\u00edpico \u00e9 a brochagem linear, que consiste em fazer passar a brocha contra a superf\u00edcie da pe\u00e7a de trabalho para gerar o corte. <\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<div class=\"ast-oembed-container\" style=\"height: 100%;\"><iframe title=\"O que \u00e9 brochagem? | Pr\u00e9via da s\u00e9rie de v\u00eddeos sobre brochamento\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/lTngKubuYjY?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/div>\n<\/div><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Brochas lineares<\/strong> s\u00e3o utilizados numa m\u00e1quina de brochar, tamb\u00e9m conhecida como brocha. <strong>Brochagem rotativa<\/strong> A brocha rotativa consiste em rodar e pressionar a brocha na pe\u00e7a de trabalho para criar uma forma axissim\u00e9trica.

Broach tools, as cutting implements, are commonly crafted from durable and abrasion-resistant materials to endure the pressures exerted during the cutting procedure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The choice of workpiece material might greatly differ based on the specific industry and application. The following are often utilized materials in the process of broaching:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Steel Alloys: <\/strong> Broaching is a frequently employed technique on a range of steel alloys, such as carbon steel, alloy steel, and tool steel. These materials are commonly found in sectors such as automotive and aerospace.<\/li>\n\n\n\n<li><strong>Aluminum:<\/strong>\u00a0 Aluminum and its alloys are often utilized, especially in industries that need lightweight components, such as aerospace and automotive.<\/li>\n\n\n\n<li><strong>Brass and Bronze:<\/strong>\u00a0 Brass and bronze are utilized in situations where it is crucial to have resistance against corrosion and good electrical conductivity, such as in electronic components.<\/li>\n\n\n\n<li><strong>Stainless Steel:<\/strong>\u00a0 Stainless steel is renowned for its exceptional resistance to corrosion and is frequently utilized, particularly in situations where hygiene and durability are of utmost importance, such as in medical equipment.<\/li>\n\n\n\n<li><strong>Cast Iron:<\/strong>\u00a0 Broaching may also be used on cast iron, a material widely employed in several sectors due to its exceptional castability and machinability.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Broaching_Methods\"><\/span>M\u00e9todos de brochagem<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Broaching provides items with very smooth surfaces and dimensional correctness. A broaching tool has rough, semi-finish, and finish cutting teeth that can complete the machining of a rough surface in a single stroke.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A broach is a single-point cutting instrument with many points that cuts similarly to a flat-ended sharp tool like a chisel. In rare circumstances, the broach teeth can be placed diagonally to complete shearing cuts, resulting in a sliding or skewing distortion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Linear_Broaching\"><\/span>Brochagem linear<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Of the numerous broach cutting methods, linear broaching is the most prevalent. The tool goes linearly over the workpiece surface, creating cuts as it approaches the end of the workpiece. The diagram is an example of linear broaching.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"611\" height=\"426\" src=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-2.png\" alt=\"\" class=\"wp-image-4932\" srcset=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-2.png 611w, https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-2-300x209.png 300w\" sizes=\"(max-width: 611px) 100vw, 611px\" \/><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pull_Broaching\"><\/span>Brochagem por tra\u00e7\u00e3o<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pull broaching involves holding the workpiece in place while the broach is drawn through. The broaches used in this technique are lengthy and require a particular head. The stress caused by tugging strengthens the broach. The procedure is often used for interior or internal broaching, although it may also be utilized for surface broaching. Pull broaches have a large number of teeth and provide a longer cut.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"624\" height=\"231\" src=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-1.png\" alt=\"\" class=\"wp-image-4931\" srcset=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-1.png 624w, https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/07\/image-1-300x111.png 300w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Pull broaching can be done vertically, horizontally, or through the workpiece. Pull broaching is used to flatten automobile cylinder blocks and heads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Push_Broaching\"><\/span>Brochagem por press\u00e3o<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A push broaching tool is shorter so that it can withstand the compressive pressures exerted when it passes through the workpiece. It has fewer teeth, which can bend or break under compressive stresses. Push broaching generates shorter cuts, resulting in smaller pieces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Surface broaching is a popular use for push broaching equipment. When used for this purpose, they are known as surface broaching tools.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Continuous_Broaching\"><\/span>Brochagem cont\u00ednua<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Continuous broaching involves keeping the broach fixed in the broaching machine while the workpiece is moved continually. The motion of the workpiece might be either linear, horizontal, or rotational. This method is commonly employed for the purpose of broaching a substantial quantity of comparable workpieces simultaneously.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Spline_Broaching\"><\/span>Brochagem de estrias<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Spline broaching, also known as round broaching, produces round, plain, or irregular splines and spiral tooth shapes. It may be used to make shafts, gears, and other mechanical components that mesh together. Spline broaching is the most frequent type of broaching, which involves using a broach to create a sequence of ridges or teeth around the perimeter of a pre-cut hole. Spline broaching is an effective way to create serrated, straight, and involute splines.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Blind_Broaching\"><\/span>Brochagem cega<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"614\" height=\"387\" src=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/05\/image-3.png\" alt=\"Blind Broaching\" class=\"wp-image-5078\" srcset=\"https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/05\/image-3.png 614w, https:\/\/broachingmach.com\/wp-content\/uploads\/2024\/05\/image-3-300x189.png 300w\" sizes=\"(max-width: 614px) 100vw, 614px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Blind broaching is the broaching procedure in which the tool does not entirely travel through the component, resulting in a blind cavity. Blind broaching is performed on pieces that are not supposed to have a passthrough. Keyways can be built to be blind broached when the tool comes to a halt in the midst of the bore.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Internal_Broaching\"><\/span>Brochagem interna<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Internal broaching removes material from the interior or internal surface of a workpiece, also known as hole broaching. Before commencing the internal broaching process, a starter hole is drilled into the workpiece, known as blank preparing. Internal broaching is used to expand, broaden, and resize holes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The internal broaching tool contains teeth that gradually get bigger to produce an excellent finish on the workpiece. Internal broaching is done with automated devices, such as a CNC machine, which can create holes in the workpiece rapidly and effectively. The internal broaching procedure can be done using either a push or a pull action. Internal broaches are categorized as round or spline.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"External_Broaching\"><\/span>Brochagem externa<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">External broaching, also known as surface broaching, removes material off the exterior of a workpiece. External broaching tools, like internal broaching tools, have teeth that gradually grow. External broaching employs a guided ram with a broach retaining device. The cutting power is supplied to the ram along the whole length of the broach.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">External broaches are flat surfaces that shape surfaces. Flat surface broaching involves passing the tool over the workpiece to obtain the required surface. The form surface broaching method is intended to generate a variety of curves and shapes, including serrated, angular spline, gear forms, fir tree, compressor slots, and keyways.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Kind_Of_Broach_Do_I_Need\"><\/span><strong>De que tipo de brocha necessito?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are some broaching applications that may be appropriate for your needs:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Automotive<\/strong>&nbsp;:The car business relies on speedy and precise mass production.

Trata-se de uma abordagem precisa para criar formas poligonais no interior ou no exterior. A brochagem rotativa consiste em colocar a ferramenta de corte num \u00e2ngulo de 1\u00b0 em rela\u00e7\u00e3o \u00e0 linha m\u00e9dia da pe\u00e7a de trabalho, resultando num efeito de cinzelagem ou de recorte.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A brochagem rotativa pode ser efectuada num torno ou numa fresadora, utilizando uma m\u00e1quina de fuso horizontal ou vertical, permitindo que o fuso gire livremente. A brochagem rotativa pode ser utilizada para gerar formas como hex\u00e1gonos, quadrados, serrilhas, rasgos de chaveta, involutos, estrias, engrenagens de dentes rectos, d\u00edgitos e letras.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong>Conclus\u00e3o&nbsp;<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">BroachingMach \u00e9 um dos melhores e maiores\u00a0<strong><a href=\"https:\/\/broachingmach.com\/pt\/about\/\" data-type=\"page\" data-id=\"141\">fabricantes de m\u00e1quinas de brochar na China,<\/a><\/strong> o maior fabricante de m\u00e1quinas de brochar.
