Many horizontal mills also feature a built-in rotary table that allows milling at various angles; this feature is called a universal table. While endmills and the other types of tools available to a vertical mill may be ...
Bryant acquired the precision external centerless grinder line from Van Norman Machine Tool Company in 1972. [4] Bryant's Soviet contracts continued to be controversial that same year. Bryant's sale of 45 precision grinders enabled the USSR to improve missile accuracy and MIRV their ICBMs. Objections to the sale were quashed by Henry Kissinger. [8]

A railgrinder (or rail grinder) is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track.
A ball mill is a type of grinder filled with grinding balls, used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
A stump grinder is a machine designed to remove tree stumps by using a rotating cutting disc that chips away the wood. The machine typically features a cutter wheel with fixed carbide teeth. The cutter wheel's movements are controlled by hydraulic cylinders , which allow it to move laterally and vertically to grind through the stump.
