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
Optional hydraulic tailstock with food pedal is available for easy loading and unloading.
Cartridge type wheel spindle is equipped with four super precision class 7 ( ABEC) bearings incorporated with 7.5 HP spindle motor ensure high accuracy.
One V and one flat hand-scraped guideways are Turcite coated and incorporated with an automatic lubrication system and micro-stepping motor. Smooth movement of the wheelhead delivers longer way life with superior positioning accuracy and repeatability.
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
