POWER-GRIP ZERO POINT CLAMPING SYSTEM Palletising and Clamping Devices from a Single Source

POWER-GRIP ZERO POINT CLAMPING SYSTEM Clamping the workpiece can be a time-consuming and cost-intensive factor especially when manufacturing individual parts and small series. This requires effective strategies to increase productivity through reduced set-up times. Palletising systems such as the Power-Grip zero point clamping system from RÖHM achieve a considerable productivity increase. This modular system meets the requirements of customer-specific solutions with the best-possible utilisation of machine capacity. Although the machine tool had to stop for the setting up time until now,...

THE BENEFITS AT A GLANCE INCREASED PRODUCTIVITY Free machine capacity through reduction of setting up time by up to 90% Minimum cleaning and maintenance work without zero point loss due to clamping mechanism on the outside HIGHEST PRECISION Repeatability of 0.002 mm over 750,000 clamping processes through cushioned, conical centring with levelling system No zero point shifting due to compensation for thermal expansion INCREASED PROCESS RELIABILITY Large pre-centring for reliable feeding of the pallets - also with automatic loading Air-flow system for cleaning and checking the levelling...

PALLETISING AND CLAMPING DEVICES FROM A SINGLE SOURCE THE SYSTEM SOLUTION As a system supplier, RÖHM doesn't just offer high-quality clamping devices, but also the matching palletising with zero point clamping. Matched to each other, the base carrier and prefabricated pallets facilitate a great variety of combination possibilities with RÖHM vices, lathe and collet chucks as well as pneumatically operated collet chucks and centric vices. Through the specifically placed tap holes, numerous RÖHM clamping devices can be mounted on the prefabricated pallets without additional reworking. Other...

RELIABLE FEEDING OF THE PALLET MISS Large offset to the side. Feeding the pallet is possible without damaging the reference surface. NEAR MISS The pallet will find its place though the positioning aid. HIT - THE PALLET IS SEATED The pallet is pre-positioned. Due to the lifting function, no reference surfaces are in contact yet. LIFTING FUNCTION Damage to all reference surfaces is prevented with large pre-centring via the outside ball cage. The pallets are raised by ca. 2 mm by the lifting function. That way, the reference surfaces only come into contact during the clamping process.

NO ZERO POINT SHIFT DESPITE THERMAL EXPANSION Classical clamping system Power-Grip system Machine table rotated by 180° Machine table rotated by 180° System zero point Workpiece zero point System and workpiece zero point CLASSICAL SYSTEMS The workpiece zero point shifts away from the system zero point through thermal changes. This shift is doubled when the machine table is rotated by 180°. Power-Grip always clamps on the system zero point in the event of thermal changes. The system zero point is maintained even when the machine table is rotated. Loss of the zero point through thermal...
