**FEATURES**:
- Heavy ribbed box-type base is made of Meehanite castings, providing excellent rigidity to ensure machine stability.
- Hydraulic, coolant and lubrication systems are separated from machine to eliminate vibration and dissipate heat.
- Sturdy rigid-designed workhead is electronically controlled giving variable spindle speeds range from 30 to 350 rpm.
- Workhead swivels 90 degrees CCW to 90 degrees CW for various grinding operations. A dual oil seal and cover prevents coolant seepage into the workhead
- The design of the tailstock is both rigid and robust. Housed is a cast body, the hardened Nitrally steel sleeve is designed to carry a MT4 center

- A special upper slide design adds 180 mm ( 7”) in total wheelhead travel and increases grinding capacity.
- Rigid table with box-type structure travel on a cushion of oil with no metal-to- metal contact.
- Table is fully supported in the full travel to avoid overhang. A swiveling able dial indicator enables rapid 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.
- The hinged, swing-down internal grinding attachment ( optional item) swinging down into working position easily and quickly.
- A patented locking device adds safety as it prevents the ID attachment from swinging down abruptly.
- 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, find increment, sparkout passes, feeding direction, parking position, retracting clearance and press cycle start to complete automatic grinding cycle.
- Optional manual level 5C lever type collet closure for quick and precise holding of work piece
