Centerless Grinding (Thru-Feed Grinding)

Midway Grinding Inc. offers thru-feed centerless grinding for applications where only the largest outside diameter is to be ground. Thru-feed grinding is best suited to grind straight, cylindrical parts with minimal slots and no interfering projections.

Parts are ground by being fed in and out through the regulating and grinding wheel in a straight line to ensure maximum grinding efficiency and therefore minimum cost. Due to the low lead times of thru-feed grinding, we can often produce lead times of less than 24 hours.

We are equipped with Cincinnati Milacron TWINGRIP models of centerless thru-feed grinders as they provide the best in stability, performance and repeatability.

We can handle dimensions ranging from .050 to 5 inches in diameter and lengths up to 12 ft.

  • Tolerances to .00080
  • Low cost, high speed, precision OD grinding
