In the numerical control lathe processing, the operator should pay attention to what matters, can better for CNC lathe processing.
Although it is similar to ordinary lathe processing, but as a result of the numerical control lathe is a clamping, automatic and continuous processing complete all turning process, so there are some place is different, we need to notice all the more.
CNC lathe processing and the matters needing attention are: 1.
Choice of rational cutting parameter of economic and effective processing way is necessarily reasonable selection of the cutting conditions, cutting speed, feed and cutting depth will directly cause the damage of the cutting tool, cutting speed, if increase, the blade temperature will rise, will produce mechanical, chemical, thermal wear.
The average cutting speed is increased by 20%, the knives' service life will reduce 1/2.
According to users of processed material, hardness, cutting condition, material type, feed and cutting depth etc. , to select and use appropriate cutting speed, regular, stable wear is the ideal condition.
Experience with selecting cutters (
Rough turning, should choose high strength, good durability knives, in order to meet the requirements of coarse car.
Fine cars, want to choose high precision, durability, good cutting tool, to ensure the precision machining
accuracy of requirements.
In order to reduce the changeover time and convenient for the knife, should try to use machine knives and machine clip blade.
Choose the fixture (
As far as possible choose general fixture clamping workpiece, do not use special fixture.
Parts positioning base should overlap, thus reduce the positioning error.
Determine the processing route,
Should be able to guarantee the precision machining accuracy and surface roughness requirements.
As far as possible to shorten processing route, thus reducing tool empty travel time.
