Precision screw machining of complex parts to close tolerances has been our specialty service since 1964. With a total of 35 single- and multi-spindle screw machines, we are able to service our customers with a range of small and large quantities. Unlike CNC machines, the Brown & Sharpe (single-spindle) screw machines can perform up to five operations at one time, and the multi-spindle machines up to 18 operations at one time, all while holding a tolerance of .001 (one thousandth) of an inch. Machines are also equipped with cross drilling and milling, eliminating the need for second operations.

Our machines have diametrical capacities that range from .032 to 3 1/4 inches. Some of the special operations our Brown & Sharpes perform are drilling, turning, internal and external threading, roller burnishing, broaching, recessing, forming, cross drilling, and milling. In addition, we have a full compliment of machines, including Hardinge lathes, Bridgeport mills, centerless grinders, lathes, and drill presses, to perform secondary operations for specific requirements.

M.A.R.'s machines parts for heat detection units used in the aircraft industry and food processing equipment, as well as several other products.

A wide variety of materials can be screw machined, including all steels, hastelloy, brass, aluminum, and several other exotic materials in round, square, and hexagonal bar stock. Parts can also be treated with a variety of finishing operations, including anodizing, hard chrome plating, nickel plating, zinc plating, and more, depending on client requirements.
