Auto indexing chuck workpiece can be turned around at both ends with only one clamping.
Indexing operates during the spindle rotation and can perform a quick change between multiple working axles.
All parts of the chuck hardened ground and lubricated directly.
Sealed against swarf, chips, and coolant.
High rigidity and high repeatability precision.
Unique indexing system and hydraulic system, with pressure detection device in the chuck, high reliability.
Indexing lathe chuck shortens the clamping time of the workpiece, and solves the problems of low manual operation efficiency and poor accuracy.
indexing chuck can improve the processing quality of the workpiece, and reduces labor strength, reduces production costs.
