The difference between tapping machine and rubbing machine and its working principle
Dec 27, 2018

The working principle of rub silk: it is two identical, rub silk face to have the tooth shape that has the same helix Angle as bolt thread same tooth shape, the bolt billet between two rub silk board when rub silk board mutual motion gives thread. A screw thread is machined by a round trip of the rubbing board at a high speed. Rubbing wire is mainly used for small bolt processing. Conclusion: tooth rubbing is the processing of the outer surface of cylindrical workpiece.

The working principle of the tooth rubbing machine: processing oblique tooth grain on the tooth plate, tooth spacing is equal to the tooth spacing to get the thread. The Angle of tooth grain is equal to the tooth rise Angle of the thread.

Tapping machine refers to the inner wall of the hole thread processing; His job is to make threads. The working principle that makes corresponding bolt or screw can join rub silk with it the working principle is two identical, rub silk face to have the tooth shape with bolt thread same same helix Angle same tooth shape, the bolt blank between two rub silk board is rubbed when rub silk board mutual motion thread. A screw thread is machined by a round trip of the rubbing board at a high speed. Rubbing wire is mainly used for small bolt processing. Conclusion: tapping is the processing of the empty inner wall, while rubbing is the processing of the outer surface of cylindrical workpiece.

Rub tooth machine is to use two identical, rub silk face to have the tooth shape that has the same helix Angle with bolt screw thread is same the tooth shape, the bolt billet between two rub silk board is rubbed the machine that gives thread when rub silk board mutual motion. The thread of a bolt is processed by rubbing the tooth plate back and forth once, and the speed is quite high. Rubbing teeth for small bolt processing.
