NEW SUPERTEC UNIVERSAL CYLINDRICAL GRINDER

15" x 24" MODEL G38P-60NC w/Automatic Infeed

NOTE:  PHOTO MAY BE OF A DIFFERENT SIZE MACHINE

FEATURES:

- 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 90°CCW to 90°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 in

a cast body, the hardened nitralloy steel sleeve is designed to

carry a MT4 center.

- Optional hydraulic tailstock with foot pedal is available for

easy loading and unloading of parts.

- 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.

- The hinged, swing-down internal grinding attachment (optional)

swings down into working position easily and quickly.  A patented

locking device adds safety as it prevents the ID attachment from

swinging down abruptly.

- 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.
