High level precision angle indexing devices
This indexing device indexes by means of 720 top and bottom, fully coupled serrations.
After each individual serration is precisely ground, they are lapped until they make full contact.
Therefore, accurate indexing is possible because each individual top and bottom serration coupled accurately and uniformly.
Moreover, deterioration of precision indexing is difficult, and precision is maintained for a long time.
Furthermore, SPID-720 is manual, and SPID-720A is motor-operated.
