At a glance:

Compensation of spindle errors
Easy handling with hydraulic expansion technology
Higher quality and longer tool life
No tool jamming
Dirt resistant and low maintenance
In order to ensure the exact radial run-out of rotating tools it is often necessary to compensate existing errors in the overall system, consisting of spindle, chuck and tool. For this MAPAL is now presenting its new alignable chuck based on the proven hydraulic expansion technology with which the errors of the overall system can be set to zero.

The hydraulic chuck is set using an alignment set with three adjustment elements. This produces high stability and functionality but with simple handling at the same time. The alignment system is sealed by a fixed ring so that it requires minimum maintenance and is dirt resistant. Alignment is made by wedges in the clamping chuck, this preventing any jamming of the tool. The self-locking of the T-nuts ensures that once set, the angle is maintained over a long period of operation.

The hydraulic chuck is ideally suited to workpiece clamping on tool grinding machines and for machining operations with high demands on tolerances and surface finish.
