Product Description

SUPERTEC STC-1206NC CENTERLESS GRINDER w/Single Axis Automatic Controlled Regulating Wheel The CII model utilizes a Mitsubishi PLC menu-driven LCD touch screen control that is easy operate, along with a servo motor for the regulating wheel.   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. FEATURES: - 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, & cylindricity. - All gears in the gearbox are made of Chrome-Molybdenum alloy steel (SNCM-21), are hardened and precision-ground for smooth running and low noise. - The hydraulic system is air cooled to maintain constant oil temperature and separated from machine to eliminate vibration and dissipate heat. - 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 tight tolerance.
