Valve Refacer

VG100 VG100A

1.Air – operated, Six – Ball chuck design for perfect alignment and grinding, only five minutes from the clamping to finish grinding, and can get a very good roundness and finish.
2.Variable valve speed allows the operator to adjust surface speed when working with different size of valves 
3.High accuracy dovetail guide of grinding wheel moving, manual scraping to reach super smooth, it can effectively absorb vibration.
4.Valve steam depth stop is a practical device, especially when you need to process several of the same valves, and allow valves to ground to the exact same length.
5.Casting iron base reduce the vibration, sturdy and durable.
6.Centralized lubricating system to avoid the cumbersome manual multi – point add oil.
7.The valve head grinding wheel and the valve steam grinding wheel are equipped with diamond dresser, very convenient dressing of grinding wheel.
8.The optional tools cabinet has a extra 2 liters coolant tank, of course, there is enough space you can change more bigger coolant tank, if you want to more coolant water. 
9.The V rest of Stem/Butt End Grinding device allows all valves in a set to be ground to the same distance from valve seat to stem end - essential for overhead camshaft type cylinder heads. Exact amount of material removed from the stem end can be measured with the micrometer adjustment system.
