High and adjustable clamping force

High clamping forces ensure a secure hold, but can also lead to deformation of the workpiece. For this reason, the PMC series offers the best solution. When the PMC is operated at maximum pressure, the centre clamping device ensures high clamping forces. If these are too high, the clamping force can be individually adjusted to suit the workpiece via the built-in differential pressure valve.

Triple clamping security

The internal design of the PMC series ensures that the workpiece remains securely held even in the event of a pressure drop. Only the pressurised operating medium can move the mechanism and thus the jaws. This effect is further enhanced by the built-in springs. This makes it impossible to move the clamp without the control medium.

Accessibility

In the PMC series, care has been taken to ensure that the workpiece is accessible from all sides. The external contour even allows the underside of the workpiece – between the workpiece and the centre clamp – to be machined using a shank cutter.

Compact

The compact design of the PMC series allows it to be used on all machining centres. Suitable centre clamps are available from Gremotool for PMC outer diameters ranging from 150 mm to 350 mm.

Low-maintenance

The chip- and water-repellent design of the PMC series prevents foreign particles from entering the mechanism. This ensures that lubrication is maintained and extends maintenance intervals. Care has been taken in the design to ensure there are no recesses where chips and water can become trapped. This allows the centre chuck to be easily cleaned using an air gun, a water gun or automatically via the machine spindle itself.

Extensive range of jaws

The entire Gremotool range of jaws can be used on the PMC series. From gripping jaws to soft aluminium jaws, all workpiece clamping requirements are catered for. The jaws are fitted with the standard Gremotool jaw system, allowing you to change them in no time at all.

Pneumatic or hydraulic

The PMC series is pneumatically operated. Alternatively, the HMC series can be used, as it has the same dimensions.

Centring accuracy

The robust construction of the PMC series prevents any displacement and guarantees precise centring of workpieces to within +/- 0.02 mm. This means there is no need to reset the zero point, thereby saving you machining time.

Short set-up times

The various mounting options for the PMC series allow you to position the clamping device precisely on the machine table in no time at all. You are free to use it on a slotted table, a perforated plate or a zero-point pallet. Media transfer is also facilitated via a quick-connect interface.

Automation solutions

Gremotool offers a range of solutions for controlling the PMC series. Whether you wish to have a robot guide a media coupling to the PMC, or control it manually via a hand valve or via the machine through a rotary joint, the choice is yours. We have solutions for the most common interfaces.
