K.O. LEE's VIGOR is a Precision Creep Feed Grinding Center designed for highly efficient full-depth grinding at an economical price.

The VIGOR is equipped with a NUM 1040 CNC color graphics control which provides simultaneous movement of the machine's three (3) axes. The table, crossfeed, and vertical axis are all driven by AC Digital Servo motors via precision ballscrews with standard linear glass scale feedback.

The VIGOR offers a full grinding capacity of 10" (250mm) by 24" (600mm) and is equipped with a standard 10-HP (7.5 kw) spindle motor capable of running up to 22,000 surface feet per minute (110 M/s). A standard frequency convertor maintains constant peripheral surface speed for the machine's 12" (300mm) diameter grinding wheel.

Machine stiffness is increased by the use of pre-loaded linear guideways on the table and crossfeed axis. All linear way bearings, ballscrews, and the spindle are lubricated by a central air / oil lubrication system that also provides positive pressure protection to these critical areas.

The low cost and quick setup of K.O. LEE's VIGOR makes this machine not only suitable for high volume production environments, but also ideal for low volume job shop applications.
