Tips of Precision CNC Turning
Precision CNC turning processing technology similar to ordinary lathe processing technology, but because of precision CNC turning is a fixture, continuous automatic processing to complete all turning operations, so we should pay attention to the following aspects.
1.Reasonable choice of cutting parameters
2.Reasonable choice tool
2.1 Roughing, to choose high strength, durability good tool.
2.2 Precise turning,to choose high precision, durability good tool, in order to ensure the machining accuracy.
2.3 In order to reduce tool change time and convenience on the knife, you should try to use the machine folder.
3.Reasonable choice of fixtures
3.1 Try to use common clamping fixture, avoid the use of special fixtures
3.2 Positioning reference parts coincide, to reduce the positioning error.
4.Determining processing route
Processing route is the exponential control machining process, the tool relative to the part of the trajectory
and direction.
4.1 It should be able to ensure the machining accuracy and surface roughness requirements.
4.2 try to shorten the processing route, reducing travel time tool empty.
5.Relate Processing route and allowance
Currently,under the conditions that CNC lathe has not reached universal access,should do the roughing by normal
lathe,especially those forging,casting parts.
6.Fixture Installation Notes
Currently, the hydraulic chuck and hydraulic clamping cylinder is connected by levers . Hydraulic chuck clamping
points are as follows: First, remove the nut with a wrench on the hydraulic cylinder, remove the stay tube, and Use a
wrench to remove the chuck retaining screws, you can remove the chuck.
