Sunnen's VR-7000 sets new standards for concentricity. The durable VR-7000 Valve Refacer features a patented centerless grinding system that is so accurate it produces concentricity to within .0004" (0,010 mm). Not only does it set new precision standards, but the VR-7000 does away with the need for chucks and collets. It is the ideal heavy-duty grinder for small, high performance and PER valves performing a variety of operations including valve facing, chamfering, and butt grinding.
Top of the line VR-7000 makes used valves "new" again...in every way: valve face roundness, face-to-stem concentricity, face finish, face angularity, stem length and tip finish.
