Power Indexing Chuck

Auto Indexing Chuck

Indexing Chuck for CNC Lathes, Milling Machines

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.

The maximum rotational speed can only be achieved when the hydraulic pressure is at its maximum. Additionally, the operating pressure and the weight of the clamping fixture must not exceed the values shown in the table above.
Indexing can be performed while the spindle is rotating. However, when indexing at high rotational speeds, it is recommended to reduce the speed by 50% to avoid vibration caused by imbalance when the workpiece is in an intermediate position. Furthermore, depending on the shape of the workpiece, indexing during spindle rotation may not be possible.
The "*" model is produced upon order, with no stock available. *Index Angle 8x45o or Specific Angle, Please contact AUTOGRIP for more detailed information.Thanks.
