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.
Some representative examples:

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:
Part |

| Stamping Die | ±.0002" | ±.0002" | ±.0002" | 16-24 Ra |
| Pump Seal | ±.0001" | .0001" | ±.0001" | 6-10 Ra |
| Drawing Die | ±.00015" | ±.00015" | ±.0001" | 10 Ra |
| Dovetail Form Tool | N/A | ±.0001" | N/A | 8-12 Ra |
| Die Set Detail | ±.0002" | ±.0002 | ±.0002" | 16-24 Ra |
Standard or custom workholding will make the VR-T adaptable to any job that requires a flat surface. The following are just some ways you can adapt the system:
 | Magnetic chuck
| Vacuum chuck
| Jaw chuck
| Mandrel
| Mechanical, hydraulic, or pneumatic clamping | |
Options such as a variable speed spindle, diamond or CBN wheels can make the VR-T one of your most versatile and productive machines.
The VR-T comes with many outstanding features which will benefit you from the very first operation.
