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.
