Creep feed grinding is a competitive operation for PGM while providing our customers with close tolerance grinding at machining costs. It truly is a cost saving operation when used correctly. PGM has been using creep feed grinding since the early 80's to manufacture critical parts with uncompromising reliability and repeatability. Specializing In
The grinding wheel speed, grinding wheel grade, depth of cut, grinding wheel material and feed rate are the important parameters that affect the surface finish, which in turn affects the productivity and cost of the component. The grinding parameters used for both surface and cylindrical operations are tabulated in table 1.

The principal defining characteristic of creep-feed grinding is a depth of cut that is high for grinding, but opinions differ on precisely what depth marks the transition. In his work involving aircraft-engine-related grinding applications, he has noted that engineers in this sector frequently mark the beginning of creep-feed at 0.015 inch.
Feed mills receive incoming ingredients by both rail and truck (including hopper-bottom, bulk-solids and liquids trailers). Rail receiving hoppers should be designed to provide maximum capacity, but are usually relatively shallow, which constrains carrying volume. Rail and truck hoppers between 1000 and 1200 bu in capacity are common.
grinding wheel. These wheels have good grinding capacity at higher speed. These are used for precision grinding of cams, rolls and other objects where high precision of surface and dimension influence the performance of operation. A resinoid bond is denoted by the letter 'B'.

In the case of precision surface grinding, feed refers to the rate of the three axes. Arguably, feed is the major deciding factors for achieving the desired surface finish. Speed refers to the wheel RPM, although interestingly, the wheel RPM is usually constant in surface grinding. This is because even though a grinding wheel does wear — a ...
