Application Details

  • 3x Through bore: Ø3.0 mm
  • Deburr size max.: Ø3.4 mm
  • Main bore: Ø11.5 mm
  • Ring groove diameter: Ø24.0 mm
  • Outer diameter component: Ø29.0 mm

COFA deburring tool, automated deburring tool, manual deburring solution

Solution: 

We have suggested the proven COFA tool system which was the first tool worldwide featuring the ability to deburr even and uneven bore edges forward and backward in one single pass. It removes the burrs radially from the bore edges without requiring to turn the work piece or to stop the spindle.

Our answer to the task: A COFA C3/3.0 standard tool with a Z spring.

Machining parameters:

Working speed of 1800 rpm, Cutting speed vc of 20 m/min.
Working feed of 0.02 mm/rev.

Results: 

The customer's main focus was the automation of the manual deburring of the cross bores.

By using the COFA tool for the automated front and back deburring of the cross bores the resulting time savings per workpiece amounted to 15 minutes.

The customer is satisfied by the deburr quality and the achieved time savings. The tool fulfilled their expectations to the full extent.
