Equipped with:
Optidress Model E - SN 7112552 A unique optical and electronic system for precision form profiling grinding wheels, functioning independently of templates, crushers and angular setting devices. Designed to increase the output and skills of the expert, and boost the confidence and productivity of the less experienced operator, by allowing him to see, and measure exactly what is happening at all stages of an otherwise complicated operation.

PG System 620 - SN 721-105 System 620 - Non-contact, on-machine precision measuring unit which overcomes skill shortages and enables operators to control to high accuracies during machining process with magnified image of 10X, 20X, 25X, 50X and 100X viewed on a high definition monitor.

Digital readout system to -.00005 and provided with reticles which show angular radial and grid graduations for direct measurement of the workpiece. This unit, when fitted to a surface grinding machine, enables constant viewing of both workpiece and grinding wheel and provides the operator with facilities normally associated w/inspection departments, thereby ensuring a higher accuracy, zero scrap, more profitability.

High Resolution Measuring Module This incorporates a high resolution CCD camera and optical lens system with reticles when coupled with the high density monitor image of workpiece can be viewed. Unit is ideally suited to a variety of machines and inspection facilities such as tool setters, cylindrical grinding applications, turning, etc. When fitted to XY slide movement coupled to a digital readout, precise movements can be achieved for accurate measurement for in-process gauging. 6 x 18

This machine came from an IBM model making shop. This tile floored and climate-controlled laboratory facility was one of the cleanest and best equipped we have seen. Those of you who have experience with IBM's manufacturing facilities will have some appreciation for the quality and condition of these goods.
