Tool life of cnc lathe machine

2017-09-20

As CNC lathe is clamping one time, continuous automatic processing all the turning process, tool life of CNC Lathe Machine should be noted that the following aspects.
For cnc lathe cutting,processed materials, cutting tools, cutting conditions are three elements in choosing reasonable cutting amount.These elements determine the processing time, tool life and processing quality.
Let us see the three elements of cutting conditions: cutting speed, feed and cutting depth,which directly lead to damage to the tool. With the cutting speed increases, the tip temperature will rise,producing mechanical, chemical, hot wear. Cutting speed increased by 20%, tool life will be reduced by 1/2.
The relationship between the feed conditions and the tool wear is generated in a very small range. When the feed is large, the cutting temperature rises, and the rear wear is large.
The effect of cutting depth on the tool is small than cutting speed and feed volume, but in the small cutting deep, the cutting material will produce hardened layer, which will affect the tool life.The user need depend on the hardness,cutting state, feed rate of the material being machined to choose the cutting speed
The most suitable processing conditions is selected on the basis of these factors.However, in the actual operation, tool wear, processing size, surface quality, cutting noise, processing heat and so on also influence the choice of tool life.
