An Analysis of the Causes of the Thread Cutting in
If the workpiece through the heat treatment before the processing of wear holes, cut from the inside of the workpiece to avoid internal stress caused by broken wire.
When the cutting is complete, you can use the magnet at the same time to suck the waste and the workpiece, or with a fixture (such as pressure plate), waiting for processing and then remove the waste.
(2) cutting the workpiece, because the waste weight itself, in the fall moment caught the key wire caused by broken wire.
(3) Casting parts in the casting process may cause trachoma, pores, the workpiece has no conductive impurities inside the cutting process may be broken wire.
(1) the workpiece after the heat treatment of the workpiece internal stress, in the cutting process caused by stress relief, clamping the key wire caused by broken wire.
