Power clamping spindles
How to clamp the largest and heaviest workpieces
Workpieces up to around 50 cm are usually clamped mechanically and manually using three- or four-jaw chucks, or automatically using pneumatics or hydraulics.
However, if the workpieces to be machined are larger, face plates are used. Using claw boxes and clamping spindles, they also hold much larger parts securely in place. Users can choose between 7 standard thread sizes from TR 50 to TR 200, with which clamping forces of up to 500 kN can be achieved thanks to the proven principle of force multiplication using a wedge clamping system.
This also achieves self-locking in every clamping position and a high degree of rigidity. The power clamping spindles are equipped with an internal automatic switchover to allow switching between external and internal clamping. The MSP/MSPD power clamping spindles from Jakob Antriebstechnik impress with very high clamping forces, a large power clamping stroke and simple operation and assembly. This ensures maximum operational safety.
In order to guarantee this in the long term, Jakob recommends (depending on the frequency of the clamping cycles) that they are checked regularly once or twice a year. This is particularly easy with Jakob force measuring systems, such as the hydraulic, self-sufficient force transducer HMD. If the clamping forces deviate from the specified target values by around 25 to 30 percent, an overhaul is advisable. Maintenance can be carried out directly by Jakob. Alternatively, Jakob also offers training courses to certify participants as operating or maintenance personnel. This means that installation and maintenance can be carried out in-house in the future to save time.
