VD4E Valve Seat Refacing Machine
| Valve seat diam. range
| Valve seat angle range
|Rotary speed range||120-250rpm|
| Transverse feed
| Supply voltage
| (1ph 50/60Hz) or
|Max. operating voltage||50VDC|
Very short refacing time!
No dust! No noise!
Powered by low operating voltage!
The machine is fitted with two motors providing a smooth cutting action. The operating voltage supplied to the motors by a compact power supply unit is of the low voltage type to eliminate electric hazards.
The exchangeable adapter head with the built-in slideway for cutting tool travel ensures a precise seat angle eliminating faulty setting operations.
Roundness, concentricity and surface finish of the refaced valve seat are within manufacturers’ specifications or even better.
Facing adapter heads are available to convert the VD4E to a
VD4E/0° Refacing machine for refacing flat landing surfaces.
A cone refacing adapter head is available to convert the VD4E to a
VD4E/-30° Refacing machine for refacing the conical landing surface on valve seat cages.
A counterboring gear head is available to convert the VD4E to a
ADM4E Counterboring machine for machine the valve seat ring bores for oversize seat ring installation.
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 cutting tool 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 the refacing pass.
