The CNC lathe of Dongguan CNC processing plant 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 makes the enterprise get rid of the backward processing technology. The processing technology of CNC lathe is similar to that of ordinary lathe, but because CNC lathe is one-time clamping, Continuous automatic machining completes all turning processes, so the following aspects should be paid attention to.
Reasonable selection of cutting parameters
Dongguan CNC machining plant for efficient metal cutting, processed materials, cutting tools, cutting conditions are three major elements. These determine the processing time, tool life and processing quality. The economic and effective machining method must be reasonable selection of cutting conditions.
The three elements of cutting conditions in Dongguan CNC machining plant: cutting speed, feed and cutting depth directly cause tool damage. With the increase of cutting speed, the temperature of tool tip will rise, which will produce mechanical, chemical and thermal wear. If the cutting speed is increased by 20%, the tool life will be reduced by 1 / 2. The relationship between the feed condition and the tool wear is very small. But when the feed rate is large, the cutting temperature rises, and the back wear is large. It has less influence on the tool than the cutting speed. Although the influence of cutting depth on the tool is not as big as cutting speed and feed rate, the hardened layer of the material to be cut will also affect the life of the tool.
Dongguan CNC machining factory would like to tell you to choose the cutting speed according to the material, hardness, cutting state, material type, feed rate and cutting depth to be processed. The most suitable processing conditions are selected on the basis of these factors. Regular and stable wear is the ideal condition. However, in the actual operation, the selection of tool life is related to tool wear, dimension change, surface quality, cutting noise, processing heat and so on. When determining the processing conditions, Dongguan CNC machining plant needs to study according to the actual situation. For stainless steel and heat-resistant alloy and other difficult to machine materials, you can use coolant or choose a rigid blade.
