CNC machining is a type of subtractive manufacturing that has been in use since the dawn of the industrial age by metal fabricators. It can involve a wide variety of processes, but the most important commonality is that each type of machining involves cutting a piece of material such as metal or plastic into a specified size and shape via a controlled removal process involving the use of machines, as opposed to power or hand tools. This can include both mills and lathes.
CNC Machining: The Basics
At its most simplistic, a machining system is made up of three parts: the CNC machine, the tool and the workpiece. These factors are combined in different ways in order to complete cutting or abrasive machining processes via the use of Computer Numerical Controlled (CNC) lathes and mills, including specialized outputs such as:
Turning — Generation of an external surface by describing a helical toolpath using a cutting tool such as a non-rotary tool bit.
Milling — Creation of precise sizes and shapes using rotary cutters to remove material by feeding or advancing a workpiece in a direction at an angle with the axis of the tool.
Grinding — Utilization of a grinding wheel as a cutting tool to produce fine finishes and precise dimensions.
Drilling — Cutting or enlarging a hole of circular cross-section via the use of a drill bit as a rotary cutting tool.
CNC Machining: Technology
The integration of technology, such as the latest versions of SolidWorks and MasterCam X, into our machine shop allows fabricators like EVS Metal to work within extremely precise tolerance parameters of +/-.001 inch at speeds of up to 12,000 RPM, while still giving customers the flexibility to produce runs as small as 5 pieces. While all four of EVS’s facilities offer CNC machining, our New Jersey and Texas metal fabrication shops specialize in machining processes and are therefore equipped to handle just about any project requested.
As a provider of fully-vertical manufacturing solutions, EVS Metal prides itself on the ability to provide a range of metal fabrication services all under one roof, including stainless steel, plastic and aluminum CNC machining. We invest in the latest technology, equipping our experienced machinists with the best equipment and software the industry has to offer in order to perform secondary sheet metal operations more efficiently. Keeping CNC machining and all other aspects of metal fabrication within our ISO 9001, ITAR-registered facilities gives us better control over quality, resulting in more consistent production and higher customer satisfaction.
