RevCut Reverse Chamfering Tool:
Chamfering Bore Exits

Defined chamfering of bores on the rear side from a drill diameter of 1.00 mm

YOUR BENEFITS

  • Eccentric pass-through of the bore achieves backside chamfering or countersinking (chamfer/countersink diameter up to 2x bore diameter)

  • Robust and stable tool:
    -> No vulnerable hinge or spring mechanism
    -> No risk of chip jamming

  • Fast machining without direction reversal or spindle stop

  • Quick and easy cutting edge change – even directly on the machine

  • Efficient tooling system through modular design and low cost per solid carbide cutting edge

  • Requires programming of 2 axes plus spindle orientation

  • Fast delivery of customer-specific cutting edges through semi-standard

FUNCTIONAL PRINCIPLE

RevCut functional principle

 

 

 

1. PASS THE BORE ECCENTRICALLY

The tool passes through the bore without rotation, stationary and offset by the eccentricity e.

 

2. BACKSIDE CHAMFERING

The tool and its basic holder are repositioned back to the bore center.
Now, with spindle rotation (clockwise), the chamfering operation is performed during retraction.

 

3. WITHDRAW FROM BORE

The tool is again offset by the eccentricity e with the cutting edge oriented and withdrawn from the bore without rotation.

 

APPLICATION EXAMPLE

RevCut countersinks on 400 stainless steel bores

Component: Power plant component
Workpiece material: 1.4901 (high-temperature resistant stainless steel)
Bore Ø: 6.3 mm
Countersink Ø 10.0 mm

On 400 bores Ø 6.3 mm of a power plant component, 120° countersinks up to countersink Ø 10.0 mm had to be applied on the bore exit side. Conventional back countersink cutters are not suitable due to the large countersink-to-bore diameter ratio. No problem for the KEMPF RevCut solution.
