Valve Grinding Machine Model: VG100 series can complete following work in five minutes: Clamping of valve stem and keep high accuracy positioning at the moment; Precision grinding of the conical surface of valve, roundness can be achieved 0.005 mm, finish can be achieved Ra0.32. The whole process is simple and perfect, very easy to use the machine, do not need specialist training, you can do that perfect work, depended on the 2×3 ball high precision pneumatic chuck. The VG100 series is new standards in speed and accuracy for valve grinding.
Centerline System is the only way to correct and align valve faces to that portion of the valve stem operating in the guide. Unless a valve is scientifically aligned, the valve face will be ground eccentric to its true center. A new valve is true and mechanically accurate in all its proportions. The valve face and stem are concentric with the same centerline.
Warping occurs only in that part of the valve that is subject to extreme heat – the portion above the guide and in the valve head. To correct a warped valve so it will function properly when replaced in the engine, the valve face must be restored to concentricity with the portion of the stem that operates in the guide. The Centerline System assures this alignment and accuracy.

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 /ButtEnd 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 .
