Mechanical parts machining refers to the process of changing the size or performance of a workpiece through a kind of mechanical equipment. So what are the precautions in the process?

1. Path sequence: Introduction to Tianjin Machida rough surface ditching knife open rough knives and so high profile rough open bold knife (ball knife) parallel milling cutter knife light knife parallel milling cutter road knife. The front mold usually has its matching copper public, to open the rough knife-based, supplemented by the local curved knife surface.

2. Machining pointed out that with a sub-surface and the pillow surface, to add time, the sub-surface of the pillow surface processing in place, leaving no margin, the cavity part of the remaining 0.2 —- 0.5, in order to sparks. If only young children, leaving a margin of 0.3 can be. Rough children are sometimes, you can leave a margin of 0.5. Before the mold touch through the bit, rub the bit can be left in the margin of 0.1, before and after the mold with the mold.

3. Open rough with large diameter round nose knife (knife handle), the tool is too small diameter knife and knife easily broken. In the knife also try to use.

4. Surface machining in the tool path to the tool center axis of the trajectory was calculated, that is, the actual machining area than the selected tool path range limit frame single side of a knife radius value, to be reasonably set the tool path range limit frame parameters to avoid Processing range beyond the actual processing needs.

5. Before the mold material is harder, before processing must be carefully checked to reduce errors, can’t be easily welded.
