Supertec (Supertek) spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of spindles and motor spindles on Supertec grinders (also spelled Supertek). Supertec is a builder of cylindrical, surface and centerless grinders founded in 1954 in Taichung, Taiwan.
Supertec, a Taiwanese precision grinding specialist
TLDR: Supertec Machinery (founded in 1954, headquartered in Taichung, Taiwan, with a US subsidiary in Paramount, California) builds manual, automatic and CNC cylindrical, surface, internal and centerless grinders.
Supertec Machinery describes itself as a specialist in precision grinding automation. Its catalogue includes surface grinders (manual, automatic, CNC), internal and external cylindrical grinders, centerless grinders and internal grinders. Its machines are sold in Asia, Europe, the United States and South America.
Depending on the listing, the name appears with two spellings, Supertec or Supertek: it is the same brand. The CNC plunge cylindrical grinders come in six capacities, from 500 to 2,000 mm between centres; recent versions use a NUM Flexium+ 8 control, while older machines used Fanuc controls.
Wheel and workhead spindles
TLDR: On Supertec plunge cylindrical grinders, the wheel runs at up to 1,390 rpm and the workhead spindle at 30 to 350 rpm, with wheels from 300 to 430 mm in diameter.
According to the manufacturer, the plunge cylindrical grinders reach 1,390 rpm at the wheel and 30 to 350 rpm at the workhead spindle, with three wheel diameters from 300 to 430 mm. A 2006 G20P-50 is listed with a Supertec spindle limited to 2,000 rpm and 500 mm between centres. Spindle bearings and lubrication are not specified in the sources we consulted: we confirm them in our quote.
