Pneumatic and electric screw driving

The open interface adapts to a variety of drives, e.g. Atlas Copco products.

Characteristics

Pneumatic drive

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

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

  • Toolbuilding

    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.
  • UNIQUICK® Advance Electro

    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.
