A stump grinder is a heavy-duty machine designed to cut the wood fibers of a tree stump and buttress roots using immense power from a spinning cutter wheel. The idea is to remove all visible traces of the woody tree parts that protrude from the ground after the tree is cut down. Stump grinders are large and expensive, and it would be unwise to …
Chris Koepfer. Editor Emeritus, Production Machining. Hard turning is typically defined as the turning of a part or barstock of harder than 45HRC on a lathe or turning center. Since surface roughness of Rmax/Rz=1.6s can be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process.

2022.11.28. Grinding in manufacturing is abrasive machining that is used to finish workpieces, understanding what the grinding process is, how it works, as well as common types of grinding.
A centerless grinding machine is accurate, simple, and productive; in through-feed centerless grinding of bushes or pins, with a good work-piece feeding system, the work-pieces simply follow each other, enter the grinder, and comes out ground continuously. The machine eliminates the time wasted on clamping and de-clamping the …
The word "topological" is often an over-used and misapplied adjective for design philosophies and manufacturing methods of gears. In the late 1970s, Maag used "Topological Modifications" with their SD series of zero degree dry grinding machines. The Maag zero degree method used single-point contact between the wheel and gear flanks ...
