NEW SUPERTEC UNIVERSAL CYLINDRICAL GRINDER

8" x 20" MODEL G20P-50M w/Manual Infeed

NOTE:  PHOTO SHOWS MODEL w/CII CONTROL

FEATURES:

- Sturdy rigid-designed workhead offers four selectable speeds from

150 to 483 rpm and swivels ±45° for various grinding operations.

- 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 MT3 center.

- Cartridge type wheel spindle is equipped with four super precision

angular contact class 7 (ABEC) bearings 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.  

- Universal table with variable speeds can swivel +3º/-5º (G20P) and

+7º/-9º (G25P) for 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.

- Optional internal grinding attachment swings down into working

position easily and quickly. It can grind workpieces with bores

ranging from 3/5"-2 ¾" and depth up to 2 ¾".

- Optional hydraulic tailstock with foot pedal is available for

easy loading and unloading of parts.
