+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.
- Mitsubishi PLC control uses a menu-driven LCD touch screen is
easy to learn and easy to set.  Simply fill in the blanks to set
