Grinding workpiece clamping chuck VMCHP

high-precisioncylindricalrotary

The pneumatic diaphragm chucks of the 6VMCHP series clamp workpieces at the highest precision. This chuck repeatably achieves a concentricity of ≤ 0.002 mm. Due to the force distribution over six jaws, plus the elasticity of the diaphragm, this chuck is particularly suitable for clamping low-deformation workpieces. The diaphragm chuck is operated via a rotary feed unit, which is screwed, through the machine spindle, directly into the chuck body. In the center of the chuck is a through-hole, which can be used for direct grinding fluid supply, air purge operation, or workpiece presence recognition. Functions & Fields of Application • For external front-end actuation • Pneumatically front-end actuated • Sealed against contamination • Ideal chuck for all cylindrical grinding machines Advantages • Highest precision ≤ 0.002mm • Sufficient opening stroke enables automated loading • Suitable for fast cycle times • Axial end-stops are directly mounted on the chuck body, ensuring high stability • Grinding fluid supply through the center • Precision interface for top jaws; no regrinding of the clamping position • Retraction effect to axial end-stop during clamping Changing jaws within micrometer tolerances is made easy! All diaphragm chucks feature precision jig-ground locating bores for precision ball positioning. This design feature ensures a quick clamping jaw change, independent of the chuck, without regrinding the jaws. Hence, this saves valuable time and increases productivity. Under optimal conditions, the jaws can be changed with an accuracy of ≤ 0.002 mm.
