TO 220 torque rotary tables.

Marca

Direct drive rotary table with impressive dynamics and extremely high degree of repeat accuracy. Freely programmable and also suitable for use in clean rooms. The direct drive rotary table allows the shortest switching times with the greatest precision. Its ability to cover a significantly more versatile range of tasks – including repeat use – helps you tap new added value potential.

Example of Application

Out with pneumatics, in with the direct drive
Cycle time cut from one second to 0.3 seconds: torque rotary table replaces pneumatic solution in test bench for precision turned parts

Challenge
Significantly reducing the cycle time – that was the key requirement demanded by the custom machine builder Gießler from their test bench performing the final quality check of tension screws used in common rail injection systems. The pneumatic rotary indexing table used previously had reached its limits.

Solution
Faster, more cost-effective and virtually maintenance-free. The arguments for switching from the pneumatic solution to the direct-drive TO 220 rotary indexing table were simply compelling. For instance, it was possible to reduce the switching time from one second to 0.3 seconds – saving time and therefore costs. In addition, the direct-drive rotary table is maintenance-free and there is also no need to regularly replace the shock absorbers of the pneumatic rotary indexing table.
