Zero point clamping system
- January 14, 2019
Röhm has introduced the Easylock zero point clamping system.
With this system the draw bolt system serves as a precision interface between the pallet carrier and the receiver unit. The pallet carrier can be fitted with vises, stationary lathe chucks, collet chucks and customized fixturing solutions. The Easylock system offer repeatability of less than 5 µm.
As a practical example, Rohm offers the situation where the setup operator has to set up a new job on a vertical machining centre. Normally, the prep needed to set up the job could take as long as two hours if all the steps are taken into account: tearing down old setup, cleaning the table and T-slots, stoning the table to remove nicks and burrs, retrieving new workholding, determining new layout, using a dial indicator, finishing the alignment, entering fixture offsets into the CNC control, entering the program, clamping the workpiece, bringing the tool to proper Z position and carefully stepping through the cuts. With the Easylock zero point clamping system, all these steps can be eliminated. This method maintains an established zero point, ensures considerably shorter setup times for the machine, and is completely automation-ready.
As a system supplier, Röhm offers palletizing as well as clamping devices from a single source. The Easylock zero point clamping system can be actuated pneumatically or hydraulically. The prefabricated pallets can be combined in a modular system with a multitude of standard clamping devices. Different sizes with diameters between 62 and 138 mm (2.44 and 5.43 in) are available. All clamping units consist of stainless steel; the receiver carrier and pallets are designed with high strength aluminum. The system is suited for manufacturing processes such as milling, grinding or drilling as well as for measurement related processes.
