Indexing Tables with hirth couplings

Servopress Automatic Indexing Tables

Servopress Indexing Tables offer superior indexing accuracy and repeatability, extremely rapid index times for high-production applications and precise locking with Hirth or Ball couplings. Drives are available in electric, pneumatic, hydraulic or combination. The potential applications for Servopress tables are endless. Tables may be utilized in environments ranging from assembly to machining; from computer assembly, to printing, to special machinery builders. They are also great for square block grinding.

For most shop and production applications, the pneumo-hydraulic models will be sufficient. They are easy to install, easy to interlock to outside commands, and are the most economical models. A compressed air outlet (60-120 PSI) is all that is needed for hook up. If loads, cutting pressures and forces become too great, a hydraulic model should be considered. These models can either be connected directly to the machine tool's hydraulic supply or can be supplied with their own independent power supply. Please contact DAPRA for assistance in selecting the indexing table that will be most appropriate for your application and budget.

Accessories

There are many options available to customize the table for your application, including: angle bases for vertical applications; special seals to keep contaminants from entering the table; position interlock return signals; pneumatic tail stocks; chucks; and more. Please contact DAPRA for a solution that is customized for your particular needs.
