Valve Seat Abrasive Grinding Wheel General Purpose Valve Grinder Grinding Wheel

Short Description:

Valve seat grinding stones used to only come in coarse and fine grinding stones. This was because valve seats were typically made of plain cast iron or hardened steel at the time. Only two abrasive specifications were needed to properly grind valve seats.Today the situation is completely different, as valve seat materials have become very specific to the application on today’s engines – alloys of multiple metals, powdered metals, super-hard materials, all designed to extend the seat’s ability to seal against the valve head.
To meet these various needs, RUIZUAN offers six different abrasive formals for grinding valve seats:General Purpose,Stellite,Nickel ,Chrome,Cool Blue,Finishing,Ruby

1.Stellite is used in many various components and is composed of 75 to 90% Cobalt and 10 to 25% Chromium with or without small amounts of other metals added. It is used especially for cutting tools, hard wear-resistant surfaces, surgical instruments, and cutlery.

2.Nickel Chrome is defined as a stainless steel containing 8% Nickel and 18% Chromium. Nickel Chrome is very resistant to wear and chemical reaction. It’s used in valve seats where we have a severe duty application such as air compressors, diesel earth movers and even some over the road trucks.

3.Cool Blue is an abrasive spec created by specifically for grinding the Copper Beryllium valve seats found in high-performance applications.

4.Ruby Stone is our best aftermarket replacement for the original Black and Decker spec. This spec was designed for use as a general purpose wheel to grind most seat alloys from the late 60s to the early 80s.
