THE VR-T DELIVERS MAXIMUM STOCK REMOVAL FOR YOUR INVESTMENT DOLLAR!

 

The vertical spindle/rotary table design provides a high wheel-to-part contact area. As a result, the VR-T removes stock faster than standard surface grinders.

The VR-T's outstanding accuracy means you'll have confidence you can work to the most demanding standard. Because the downfeed is controlled by our proven Incrematic Downfeed System, you can count on years of "tenth" repeatability. And Gallmeyer & Livingston's legendary machine tolerances will enable you to hold tight flatness, parallelism and finish specs. The above parts were tested to the following tolerances:
