OPERATION
The Bryant Center Hole Grinder produces geometrically correct center holes – a vital requirement for precision O.D. grinding. Ideal for re-centering distorted centers in machine spindles, arbors, center-controlled checking devise & for other salvage work.
It minimizes stock removal and greatly improves work quality and accuracy. Operation of the Bryant Grinder is unique – instead of utilizing plunge grinding, with its inherent faults, it “Generates” to produce fine finishes and precision tolerances similar to those obtained on an internal grinder. High Precision 3-way grinding to the cone-shaped wheels are – Rotary Motion of the Grinding Cone above its spindle axis; Planetary motion of the Grinding Cone about its spindle axis; Reciprocating motion of the Grinding Cone along a line 30 degrees from the vertical.
