CNC lathe is a high-precision, high-efficiency automatic machine tool. Using CNC lathe can improve processing efficiency and invent more value. The appearance of CNC lathe frees the enterprise from the backward processing technology, CNC lathe processing technology and ordinary lathe The processing technology is similar, but since the CNC lathe is a one-time clamping, continuous automatic processing completes all turning operations, and the CNC lathe processing reasonably selects the cutting amount skill, should pay attention to the following aspects.
　　Regarding high-efficiency metal cutting, the processed materials, cutting tools, and cutting conditions are three major factors. These decisions address processing time, tool life and process quality. A cost-effective processing method must be a reasonable choice of cutting conditions.
　　The three elements of the cutting conditions: cutting speed, feed rate and depth of cut directly cause damage to the tool. As the cutting speed progresses, the tip temperature rises, producing mechanical, chemical, and thermal wear. Cutting speed is increased by 20% and tool life is reduced by 1/2.
　　The feed condition is related to the wear behind the tool in a very small range. However, the feed rate is large, the cutting temperature rises, and the rear wear is large. It has less effect on the tool than the cutting speed. Although the depth of cut has no effect on the cutting speed and the feed rate is large, in the case of small depth cutting, the hardened layer is produced by the cutting data, which also affects the life of the tool.
　　The customer should select the cutting speed to be used according to the processed data, hardness, cutting state, data type, feed rate, and depth of cut.
　　The selection of more suitable processing conditions is selected on the basis of these elements. Regular, stable wear and longevity is the ideal condition.
　　However, in theoretical work, the choice of tool life is related to tool wear, dimensional changes in processing, appearance quality, cutting noise, and processing heat. When affirming the processing conditions, the demand is suspended based on the theoretical situation. For hard-to-machine materials such as stainless steel and heat-resistant alloys, it is possible to use a coolant or a rigid blade.
