<\/p>\n\n\n\n

Humans do not<\/em> like change. Believe it or not, after calculators were invented, some people refused to give up their slide rules. Similarly, CNC machining was invented decades ago, yet there are still those who prefer manual machining techniques. This preference persists despite CNC technology\u2019s ability to manufacture and replicate precision parts that are fully interchangeable with one another, while manual methods must make mating components as matched sets or produce custom replacements. <\/p>\n\n\n\n

The Different Types of CNC Machines<\/h2>\n\n\n\n

CNC machining can produce a wide array of parts from the simplest component to the most complex assembly<\/a>. Need to machine a gear shaft for a vehicle? Or an inlet for a heat exchanger shell on a military transport vehicle? What about a precision electrical contact for a fighter jet or a lifesaving pacemaker? <\/p>\n\n\n\n

CNC<\/a> is the process of \u201cfeeding\u201d a set of sequenced instructions into a specially designed, programmable controller and then using it to direct the movements of a machine tool. In all methods of CNC operation, data input and computer-controlled and monitored feedback are critical parts of the machining process. The path the tooling takes in removing material is also controlled by computer programming and calculations involving complex algorithms or interpolation. <\/p>\n\n\n\n

Listed below are the most common types of CNC machines and a breakdown of their typical uses and capabilities as compared to manual machines. <\/p>\n\n\n\n

Operation Overview <\/h3>\n\n\n\n

CNC mills<\/a> remove material from a workpiece that\u2019s fixtured to a table via contact with a mobile, rotating tool. Typically, the mill has multiple degrees of freedom which allows for machining on multiple planes with one setup\/fixture. CNC mills are best for high-precision, high-speed manufacturing, and can drill, form slots, facilitate planing, cut grooves, and engrave material.<\/p>\n\n\n\n

Types of Parts <\/h3>\n\n\n\n

CNC Mills can be utilized to make a variety of parts with intricate geometries, such as: <\/p>\n\n\n\n
