Advantages:
Extremely short machining time!
No abrasive dust!
No noise!

Working Principle:
The valve seat is refaced to the preset depth by the simultaneous application of both a rotary and a transverse feed motion to the single point cutter.

While the cutter rotates in a circle around the valve seat, a feed gear mechanism ensures a continuous outward transverse feed motion under the proper seat angle. This angle is defined by an inclined slideway provided for the tool slide in the exchangable adapter head. The lathe-type refacing action provides a flawless concentric seating surface texture for a complete valve seal.

Handling:
Setup is fast and easy.
First, lock the pilot with mounted centering spider in the valve guide. Then, lower the machine over the pilot and position the cutter in front of the inner edge of the valve seat. Turn micrometer downfeed to set the desired depth of cut.
Refacing is automatic. Pressing one button is enough to start both the rotation and the transverse feed of the cutter.

Features:
Power drive unit includes two low voltage motors providing smooth cutting action.
Exchangeable adapter head with built-in slideway for cutter travel ensures precise seat angle. Roundness, concentricity and surface finish are within manufacturers’ specifications or even better.
The machine has been tested and approved by the leading engine manufacturers.
