Slotted precision turned sleeve in bright machined metal, from a range of turned parts made in diameters from 1 mm to 50 mm. A deep cross slot splits one end into two prongs, and the other end carries a centre bore with a turned groove just above it. Fine turned grooves run around the slotted end. The parts are produced from ferrous and non-ferrous metals in lot sizes from 1000 to millions of parts. Turning runs on CNC Swiss type sliding headstock turning centers, CNC single spindle turret machines, CNC turn mill centers, 2 axis CNC turning centers, multi spindle machines and cam operated Swiss type automatic lathes. Centerless and cylindrical grinding and honing are done in-house; heat and surface treatment are outsourced.
