What Supertec Machinery does

Supertec Machinery is a precision grinding machine manufacturer founded in 1954 in Taiwan, with US sales and service operations established in 1997 in Paramount, California. The company designs and sells a comprehensive portfolio of grinding machines spanning seven major categories: surface grinders (saddle, column, over-arm, and double-column types), cylindrical grinders (NC and CNC plunge, angular, universal, CAM, compact, and roll configurations), universal ID/OD grinders, centerless grinders, vertical grinders, rotary grinders, and double disc grinders. Core technology centers on mechanical precision engineering, including cartridge spindles with class 7 (ABEC) bearings, Turcite-coated slideways, Heidenhain linear scales with 0.000002 inch resolution, Fanuc/Mitsubishi/Siemens/Bosch Rexroth CNC controls, and a proprietary i-Grind conversational programming interface that lowers the barrier to CNC operation. Machine tolerances of 0.0001 inch or better are achievable across the product line.
