With burrs applied, these machines are able to reach an astonishing surface finish of Ra ≤ 0.2μm and a dimensional tolerance of ±0.001mm. The shaft diameters which cylindrical grinders handle range from 5mm to 500mm, and centerless configurations are offered for bulk production. Surface grinders can handle flat plates 1000mm by 500mm in dimensions. The use of in-process gauging and coolant filtration on these machines helps improve multi-stage performance, crucial for the manufacturing of aerospace bearings or optical lenses, complying with ISO 4955 grinding accuracy standards.
