  • Getting Centered With Centerless Modern Machine

    2007-12-14 · Even though the shop deems OD grinding as the best means by which to achieve roundness between 10 to 20 millionths while accurately holding features relative to other features, this method is not a match for all of its incoming jobs. Mr. Shegda finds that customers often mistakenly think that they need to grind between centers, when in fact they need the capabilities of centerless. OD grinding can be problematic for parts with high length-to-diameter ratios, for example.
