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

Working Principle:
The VD 5E machines the valve seat in a lathe-type facing action.The valve seat is refaced to the preset depth by the simultaneous appli-cation of both a rotary and a trans-verse feed motion to the single point carbide 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 for the tool slide carrying the cutter. The lathe-type refacing action provides a flawless concentric seating surface texture for a complete valve seal.

Features:
The machine is fitted with two motors providing smooth cutting action.The speed of the motors is infinitely adjustable so that the cutting speed can be adapted to the diameter and material of the valve seat.The controls are housed in a separate power supply unit for ease of handling.The exchangeable adapter head with built-in slideway for cutter travel ensures a precise seat angle.The machine has been tested and approved by a leading slow speed engine manufacturer.

Handling:
Set up is fast and easy. First, lock the pilot 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 infeed to set the desired depth of cut. Refacing is automatic.
Pressing one button is enough to start rotation and transverse feed of the cutter.
