centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels and the speed of their rotation relative to each other determines the rate at which material

if 75 percent of critical speed is considered desirable for efficient grinding in a 2.4 meter (8 foot) diameter mill then the same will be true for a 5.0 meter (15½ foot) diameter mill.
creep-feed grinding is a milling process. however because the work is grinding instead of milling (milling in the conventional sense that is) the machine had to deliver the sort of stiffness that is a key strength of the traditional horizontal platform. unlike a typical vmc the rigid cast iron base of this machine weighs 30100 pounds.
milling is using carbide burs to cut into the block with a punching motion. a large carbide does the majority of the work and then a finer finishing bur completes the details. there may be multiple sprue connections. it is currently limited to bi
