These machines come in two varieties that perform similar functions differently:\r\n<ol>\r\n \t<li><strong>Horizontal Boring Mills.<\/strong>\u00a0These machines let the workpiece rest on the table of the machine while the boring bar rotates around a horizontal axis. Some have compared this to the operation of a horizontal milling machine.<\/li>\r\n \t<li><strong>Vertical Boring Mills.<\/strong>\u00a0With these boring mills (or often referred to as a VTL), the workpiece rotates around a vertical axis while the boring tool moves in a linear fashion\u2014i.e. without turning. In some ways, this is similar to a vertical lathe.<\/li>\r\n<\/ol>\r\n<h2><strong>What Are Boring Mills Used For?<\/strong><\/h2>\r\nBoring mill machines are primarily used to enlarge holes where other processes would be cost-prohibitive, inefficient, or inaccurate. A couple of key uses include:\r\n<ul>\r\n \t<li><strong>Roughing\/Finishing Internal Surfaces.<\/strong>\u00a0One of the key uses of a CNC boring mill is to roughen or smooth out the interior surfaces of a cut hole. Here, the tool used can help texture the surface of the hole\u2019s interior in a specific way. This is sometimes done when reconditioning a product rather than making a new one.<\/li>\r\n \t<li><strong>Boring Heat-Sensitive or Non-Ductile Materials.<\/strong>\u00a0As a physical shearing process, boring milling machines can enlarge holes in materials that are unsuited to thermal or electric-based hole-making methods (such as\u00a0laser cutting\u00a0or <a href=\"https:\/\/newusedmachines.com\/us\/product-category\/electrical-discharge-machine\/\">electric discharge machining<\/a>).<\/li>\r\n<\/ul>\r\nManual boring machines are best suited for expanding through holes. While CNC boring mill machines may have the precision necessary to drill blind or partial holes, this is still not their preferred application.\r\n<h2><strong>Benefits of Boring Milling Machines<\/strong><\/h2>\r\nSo, if a CNC horizontal boring mill is kind of like a specialized horizontal milling machine, and a vertical boring mill is like a vertical lathe (albeit with it expanding a hole rather than stripping the outer layer of a workpiece), why would you want a boring mill instead of one of these other machines for your machine shop?\r\n\r\nA few reasons include:\r\n<ul>\r\n \t<li><strong>Boring Mills Can Handle Extremely Large Parts.<\/strong>\u00a0Some machine shops have to mill very large workpieces, and this is where boring milling machines excel. A boring mill has a very large \u201cconfigurable envelope,\u201d which lets it mount larger workpieces than a similar horizontal milling machine.<\/li>\r\n \t<li><strong>Minimizing Tool Deflection.<\/strong>\u00a0Tool deflection, or the deviation of a machining process, happens when a tool encounters resistance greater than what it can easily compensate for\u2014such as when a spindle is extended too far from its anchor, causing it to drill at an unusual angle when placed under an excessive force. With boring mills, the spindle advances from the headstock, which means it can be kept short to prevent tool deflection. This results in more consistent drilling.<\/li>\r\n \t<li><strong>Durability and Useful Life.<\/strong>\u00a0Boring mills might not be exciting, but they are incredibly sturdy and reliable tools\u2014especially when they\u2019re well-maintained. They can last for decades of consistent use with the proper care\u2014making used CNC boring mill machines particularly desirable investments that retain their value.<\/li>\r\n<\/ul>\r\nSource: <a href=\"https:\/\/www.southernfabsales.com\/blog\/boring-mill-benefits\">Southern Fabricating Machinery Sales<\/a>","link":"https:\/\/newusedmachines.com\/ca\/product-category\/boring-mills\/","name":"Boring Mills","slug":"boring-mills","taxonomy":"product_cat","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/newusedmachines.com\/ca\/wp-json\/wp\/v2\/product_cat\/665"}],"collection":[{"href":"https:\/\/newusedmachines.com\/ca\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/newusedmachines.com\/ca\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/newusedmachines.com\/ca\/wp-json\/wp\/v2\/product?product_cat=665"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
