Pneumatic drive
- Slip clutch will limit the maximum torque used in order to handle smaller peaks
- Shut-off clutch is very precise on torques. It can handle high quality applications.
Pneumatic and electric screw driving
The open interface adapts to a variety of drives, e.g. Atlas Copco products.
Characteristics
Pneumatic drive
- With slip clutch; suitable for differing conditions of hardness of the material used
- High precision due to shut-off clutch
- Robust
Electric drive
- Short cycle times but maximum efficiency
- Low noise
- Clean air working surroundings
- High-precision driving cycles
- Process monitoring
Choice of the correct drive is being influenced by the following criteria:
- Torque and its precision
- Geometry of the screw and xgaracter of the fastening position
- Number of reolutions needed and their characteristics
- Necessary availability of the unit
- Average offset
- Necessary cycle time
- Assembly and components
- Reproduceability and shut-off accuracy
- Behavior on noise and environment issues
- Necessary control and regulation behavior
- Designated fastening process
- Power and weight, and/or size, type of clutch
- Energy costs
Technology
Types of drives
-
-
Electric drive
- High productivity due to higher motor rotation speed and therefore greater spindle torque
- Electric drives ensure the quality of the assembled products. Torque and rotation angle are being monitored during the screw driving process. Misdriven and overturned screws are recognized by the driver.
