tolerance requirements for grinding machine ways
Feb 07, 2018 · tolerance requirements for grinding machine ways There is a mixture of mystique and magic around these machines but I would like to get a good handle on the facts without the BS. What do I need to require of the grinding house to achieve the performance this machine is capable of by design.
Machine Processing and Tolerance Grades
A tolerance is the total permissible variation of size. where the tolerance is the difference between the limits of size. Range of tolerance grades that various machine processes may …
How We Hold Tolerances - Nelson Grinding
How We Hold Tolerances Most grinding is done by abrasive wheels that rotate at high speed, or by power-driven cloth or stone belts coated with an abrasive. In precision grinding the same methods are used, but with extreme precision in the grinding process.
grinding tolerances - Practical Machinist
Nov 17, 2003 · Cant speak for grinding shops around the country, but I would never expect the grinding shops I deal with to hold size to +/- 1/2 a tenth. About +/-.0002 is the best I would expect. Wouldnt a part need lapping to get that tolerance?

Grinding machine - Wikipedia
Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns.
Grinding (abrasive cutting) - Wikipedia
Tolerances for cylindrical grinding are held within ±0.0005 inches (13 μm) for diameter and ±0.0001 inches (2.5 μm) for roundness. Precision work can reach tolerances as high as ±0.00005 inches (1.3 μm) for diameter and ±0.00001 inches (0.25 μm) for roundness.
Blanchard Grinding | Precision Grinding, Inc.
Grinding Tolerances. Flatness tolerances are met by shimming the work piece, flipping the work piece, and sparking out until tolerances are met. Common parallelism tolerances for Blanchard grinding range from within .003″ to within .010″, often times depending upon the size of the part.
