Sharp Industries Cylindrical Grinders

Sharp Industries Cylindrical Grinders

• Study rigid-design workhead offers variable speed from 30 to 350 rpm swivels +/- 45 degrees for various grinding operations.
• The design of the tailstock is both rigid and robust. Housed in a cast body, the hardened Nitrally steel sleeve is designed to carry a MT3 center.
• Cartridge type wheel spindle is equipped with our super precision angular contact class 7 ( ABEC) bearings ensure high accuracy
• One V and one flathand-scarped guideways are Turcite costed and incorporated withan automatic lubrication system and micro-stepping motor. Smooth movement of the wheelhead delivers longer way life with superior positioning accuracy and repeatability
• Universal table with variable speeds can be swiveled up to 7 degrees in either direction for cylindricity corrections and taper grinding applications
• Slideways, leadscrews are continuously lubricated by an auto-lube system to ensure long service life and maintain maximum accuracy
• Optional internal grinding attachment swings down into working position easily and quickly. It can grind workpieces with bores ranging from diameter 24 to 70 mm ( 0.94”- 2.76”) and depth up to 70 mm ( 2.76”)
• Optional hydraulic tailstock with footpedal is available for easy loading and uploading of parts.
• PLC control uses a menu driven LCD touch screen is easy to learn and easy to set. Simply fill in the blanks to set total grinding amount, rough increment, fine increment, sparkout passs, feeding direction, parking positon , retracting clearance and press cycle start to complete automatic grinding cycle( SE version only)
