PRECISION SURFACE GRINDERS

SUPERABRASIVES GRINDER The VC612 machine was developed especially to rough and finish grind friable materials such as carbides. fer- rites, alumina, ceramics, quartz and other exotics. It deep grinds in one pass with no electrical assist and no corrosive salts. A three phase spindle power controller monitors power consumed to prevent overfeeding which could cause wheel damage. The slow range table speed adjusts by a micrometer valve for precise and repeatable settings. A two-speed spindle allows for standard and heavy stock removal grinding.
