CNC processing is also called computer gongs, CNCCH or CNC machine tools is actually a call over in Hong Kong, later introduced to the mainland Pearl River Delta, in fact, is the CNC milling machine, in Guang, Jiangsu, Zhejiang and Shanghai, someone called "CNC machining center" it is used in an extremely wide range, compared to other processing technology has more advantages. Important we mastered the following skills, in the processing can be more smooth.
1. White steel knife speed should not be too fast.
2. the copper worker open rough less use white steel knife, more use of flying knife or alloy knife
3. when the workpiece is too high, it should be layered with different lengths of knives for roughing.
4. with a large knife to open the rough, the application of small knives and then remove the remaining material, to ensure that the balance is consistent before the light knife.
5. flat application flat bottom knife processing, less ball knife processing, in order to reduce processing time.
6. brass work to clear the corner, first check the corner on the R size, and then determine how much to use the ball knife.
7. calibration table plane four corners to gong flat.
8. Where the slope is an integer, apply the slope knife processing, such as the pipe position.
9. before doing each process, think clearly about the amount of spare capacity left after the previous process, in order to avoid empty knives or
processing too much and knives.
10. try to take the simple knife path, such as shape, grooving, single-sided, less go around the same height.
11. take WCUT, can take FINISH, do not take ROUGH.
12. when the shape of the light knife, first rough light, then fine light, the workpiece is too high, first light edge, then light bottom.
13. Set the tolerance reasonably to balance the machining accuracy and computer calculation time. When roughing, set the tolerance to 1/5 of
the margin, and when varnishing, set the tolerance to 0.01.
14. Do more processes to reduce empty tool time. Do a little more thinking to reduce the chance of making mistakes. Make more auxiliary lines and surfaces to improve the machining condition. 15.
15. Establish a sense of responsibility and check each parameter carefully to avoid rework.
16. Be diligent in learning, good at thinking, and keep improving. Milling non-planar, use more ball cutters, less end cutters, don't be afraid to join the cutters; small cutters to clear the corners, large cutters to refine; don't be afraid to make up the surface, proper making up the surface can improve the processing speed and beautify the processing effect.
