Advance Hydraulic Pressure ON → Contact Workpiece (Fixing Completed) → Lock Hydraulic Pressure ON →Advance Hydraulic Pressure OFF → (Lock Completed).
When lock action is completed, do not retain hydraulic advance pressure supplied. Otherwise, if the workpiece is dislocated,

All-In-One High Precision Locating and Powerful Clamping!

C en t er i ng Pa lle t C la mp
3μm Repeated Locating Accuracy
Just one datum clamp enables both X and Y locating and clamping.
The clamp includes seating surfaces, built-in seat check valves andair blow capabilities.【Locating Repeatability：3μm】

Clamping Function
Spring clamp and hydraulic release.

Self Absorbing Taper Sleeve
Marginal error absorbed by the taper sleeve.
The clearance between the clamp, taper sleeve andfemale block is eliminated. This enables the repeatedlocating accuracy and stabilized clamping force.
