MAPAL Introduces Hydraulic Chucks For Tool Grinding

MAPAL Introduces Hydraulic Chucks For Tool Grinding

Added to MTDCNC by MAPAL on 31 May 2017

The new hydraulic chucks ensure remarkably high-precision clamping and repeatability during grinding. The impressive line of  hydraulic chucks are manufactured for the shank tolerance h6 band and this new MAPAL line also demonstrates exceptionally low wear characteristics that makes the HydroChuck Grind-A and the HydroChuck Grind-M extremely cost-effective for end users.

In addition to the high radial run-out accuracy, the automatic workpiece clamping of the HydroChuck Grind-A is characterised in particular by its energy-efficient function. The workpiece is clamped by means of an innovative cup spring pack. This ensures the hydraulics of the machine are only required for releasing the workpiece. The hydraulic chuck can be rapidly set and adjusted in just a few minutes to micron precision using two dial gauges. 

Any 'wobble' can be compensated and this results in maximum workpiece precision. In addition, a uniform material removal and high surface finish quality is guaranteed. In designing this new HydroChuck line, MAPAL has paid particular attention to minimising access restrictions to the tool and achieving the best possible grinding wheel run-out. The new chuck significantly reduces the wear upon the grinding wheel whilst delivering a constant quality and form/dimensional accuracy of the workpiece. 

In addition to the HydroChuck Grind-A, MAPAL also offers the new HydroChuck Grind-M for manual workpiece clamping. With the HydroChuck Grind-M, the tool to be ground is clamped manually using a hexagonal head screw. This chuck also allows the benefits of the hydraulic expansion technology to now be used for tool grinding.

The HydroChuck Grind-A is available for the clamping of tool shank diameters of 20mm whereas the HydroChuck Grind-M has been developed for 12, 20 and 32mm tool diameters. To make the HydroChuck Grind-A and the HydroChuck Grind-M completely flexible, reducing sleeves are available to accommodate common tool shank sizes.
