In people's daily life, as well as industrial and agricultural production departments, scientific research units, and national defense departments, a large number of various machines, instruments and tools are used. Most of these machines, instruments, and tools are subject to ink of metal parts of a certain shape and size. Metal parts from rough to qualified products generally need to be processed by mechanical processing. In the mechanical processing, a variety of machine tools are used, and metal cutting machines are commonly used.
Metal cutting machine tool is a machine that is processed into a machine parts with a cutting method into a machine. It is a machine that manufactures machines, called ": work -making machine machine" or "tool machine". People are used to machine tools/(Machine Tools / /). Common machine tools include lathe, milling machines, beds, planes, grinding machines, drilling machines, testers, beds, cutting off machine tools, gear plus: I: machine tools, thread processing machine tools and electric processing machine tools. With the development of science and technology, Americans also invented digital control/(NU -Merical Control/) and CNC machine tools/(Numerical Control Machine Tools/)
Digital control is a method of controlling the motion and processing process of machine tools with digital signals. It is also an automatic control technology, referred to as CNC/(NC/). Use a computer to control the processing function to achieve digital control, called computer CNC
