STANDARD FEATURES:
– Mitsubishi PLC control uses a menu-driven
LCD touch screen – it is easy to learn and easy
to set-up. Simply fill in the blanks to set
the total grinding amount, rough increment,
fine increment, spark-out passes, feeding direction,
parking position, and retracting clearance – then
press cycle start to complete an automatic
grinding cycle.
– Heavily ribbed box-type base is made of
Meehanite castings, providing excellent rigidity
to ensure machine stability.
– Hydraulics, 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 ranging from 30-350RPM.
Workhead swivels 90CCW to 90CW 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 in a cast body, the hardened nitralloy
steel sleeve is designed to carry a MT4 center.
– Cartridge type wheel spindle is equipped with four
super precision class 7 (ABEC) bearings incorporated
with 7 1/2 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 7″ (180mm)
in total wheelhead travel and increases grinding
capacity.
– Rigid table with box-type structure travels on
a cushion of oil with no metal-to-metal contact.
Table is fully supported in the full
travel to avoid overhang.
– A swiveling table 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.

– Upgrade from 7.5 H.P. to 10 H.P. Spindle
Motor.
