Problem/Question

Service punch deforms the hole when running automatically with the rollformer but works correctly in manual mode.

Deformed holes

Possible Causes

  • Punch not fully seated or tightened.
  • Hydraulic oil pressure too low, causing slow punch retraction.
  • Cold oil conditions increasing viscosity and slowing punch speed.

Possible resolution

  • Verify that the punch is fully seated and locked in place.
  • Inspect the hydraulic pressure gauge while running a service punch operation.
  • Ensure system oil pressure matches factory specifications.
  • If operating in cold environments, warm up the oil before starting production to restore correct punch speed.

Quick Tip

  • Always check oil level first if drive errors appear.
  • Loose wiring in the E-stop circuit can mimic drive fault conditions.
  • Verify both hardware (drives, wiring) and software (ScotRF error logs).
