CNC lathe is a kind of high-precision and high-efficiency automatic machine tool. The use of CNC lathe can improve processing efficiency and create more value. The emergence of CNC lathe has freed companies from outdated processing technology. The technology of CNC lathe processing is comparable to ordinary lathes. The machining process is similar, but because the CNC lathe is a one-time clamping and continuous and automatic processing completes all the turning procedures, the CNC lathe processing is reasonable in selecting the cutting amount skills, and the following aspects should be paid attention to.
For high-efficiency metal cutting processing, the processed material, cutting tool, and cutting conditions are the three major elements. These determine the processing time, tool life and processing quality. The economical and effective machining method must be the reasonable choice of cutting conditions.
The three elements of CNC lathe cutting conditions: cutting speed, feed rate and depth of cut directly cause tool damage. With the increase in cutting speed, the temperature of the tool tip will rise, which will cause mechanical, chemical, and thermal wear. Cutting speed increased by 20%, tool life will be reduced by 1/2.
The relationship between the feed condition and the wear of the tool back is generated in a very small range. However, the CNC lathe has a large feed rate, the cutting temperature rises, and the back wear is large. It has less influence on the tool than cutting speed.
Although the influence of cutting depth on the tool is not as large as the cutting speed and feed rate, when cutting at a small depth of cut, the material being cut will produce a hardened layer, which will also affect the life of the tool.
Customers should choose the cutting speed to be used according to the processed material, hardness, cutting state, material type, feed rate, depth of cut, etc.
The selection of more suitable processing conditions is selected on the basis of these factors. Regular, stable wear and longevity are the ideal conditions.
However, in the actual operation of CNC lathes, the choice of tool life is related to tool wear, dimensional changes to be processed, surface quality, cutting noise, and processing heat.
When determining the processing conditions on a CNC lathe, it is necessary to conduct research according to the actual situation. For difficult-to-process materials such as stainless steel and heat-resistant alloys, coolants or blades with good rigidity can be used.
