Simply fill in the blanks to set total grind amount, rough grind amount, fine grind amount, dwell times, and retracting clearance, then press cycle start to complete the automatic grinding cycle. - Both grinding & regulating wheel spindles are made of NI-CR-MO alloy steel, which is normalized and carbonized hardened and ground for longer life and better accuracy. - Hydrostatic Babbitt bearings type spindle with a 3-point support design, surrounded by a high pressure oil film, eliminates metal-to-metal contact to provide heavy duty grinding capability as well as high vibration damping performance. - A pressure switch interlock prevents spindle start-up until oil pressure is established. - This pressure switch interlock also stops the spindle if oil pressure fails for longer spindle life. - The regulating wheel travels on double V ways are hand-scraped and Turcite coated for precise and smooth movement to ensure high accuracy and longer way life. - Both grinding & regulating wheels equip with hydraulic dressing unit. Dressing speed is infinitely variable. Various profile dressing can be achieved with optional template. - Hydraulic dressing unit for the regulating wheel can be rapidly and precisely swiveled up to ±3° for grinding taper in infeed grinding and for providing better contact between workpiece and grinding wheel to achieve better surface roughness, roundness, - All gears in the gearbox are made of Chrome-Molybdenum alloy steel (SNCM-21), are hardened and precision-ground for smooth - The hydraulic system is air cooled to maintain constant oil temperature and separated from machine to eliminate vibration - The optional servo driven variable speed regulating wheel helps to achieve optimal surface speed for a better cutting capability and a superior surface finish. - Optional automatic loading & unloading for infeed & thrufeed can be custom-built to meet your requirements, allowing the machine to be run unattended, at a high production rate, while maintaining a Work diameter (with standard workrest): 0.04~1.18 Work diameter (with special workrest): 1.18~2 Wheel size (Diameter x Width x Bore): 12x 6x 5 Dressing increment (per graduation): 0.0005 Dressing increment (per revolution): 0.05 Wheel size (dia x width x bore): 8x 6x 3.5 Spindle speeds (10 steps): 15~310 rpm Handwheel per graduation: 0.002 Handwheel per revolution: 0.2 Dressing increment per graduation: 0.0005 Dressing increment per revolution: 0.05" Rapid feeding of saddle handwheel Micro feeding of saddle handwheel - Grinding wheel with flange - Coolant system - Regulating wheel with flange - Diamond tools - Wheel balancing arbor - Standard thrufeed blade - Levelling bolts with blocks - Standard thrufeed workrest - Maintenance tools & tool box - Wheel extractor - Heat exchanger for hydraulic system Options & Extras (call for pricing): - Hydraulic auto infeed attachment - Std. auto vibration feeder (dia. 400mm) - Automatic loading & unloading attachment for infeed - Automatic loading for thrufeed - Outgoing conveyor & receiver - Coolant system w/mag. sep. & paper filter (20L/min, 80L) - Coolant system w/mag. sep. & paper filter (60L/min, 140L) - Coolant system w/magnetic separator (20L/min, 83L) - Coolant system w/magnetic separator (40L/min, 172L) - Coolant system w/paper filter (20L/min, 80L) - Coolant system w/paper filter (60L/min, 140L) - Grinding wheel (12"x6"x5", 38A) - Regulating wheel (8"x6"x3.5", A) - Thrufeed workrest (0.04" - 1.18") - Special thrufeed workrest (1.18" - 2") - Infeed workrest (0.04" - 2") - Thrufeed blade (various sizes) - Infeed blade (various sizes) - Balancing stand for STC-12 (straight type) - Input rail & output rail (L: 8"/ea) - Long thrufeed guides (6ft/ea) w/stands - Servo driven variable speed regulating wheel Machine Location: HARRISON, NJ Click Here For More Supertec Machines Click Here For More Grinders, Lappers & Hones - CENTERLESS GRINDERS(s) Call Kori at ext 7555 Call Alex at ext 7613 Finance This Equipment For Your Business - Click Here Finance Equipment For Your Business - Click Here * Machinery Values is one of the world's largest machinery dealers, in business since 1971. * New machines are covered under their own warrantees.
