Features and Benefits:
Clausing Industrial Inc. high precision cylinder grinders are unmatched in structural rigidity and stability, grinding accuracy and operational convenience. Each machine provides maximum operational flexibility thereby allowing for various grinding operations. You will get extra value when putting Clausing cylinder grinders on your production line. NC computer controlled combined with conversational operation for maximum operator convenience.
The grinding wheel spindle is precision machined from high quality SNCM220 alloy steel normalized and tempered, carburized and sub-zero treated, precision ground and mirror-effect treated to over HRC62 hardness. The wheel spindle runs by using special hydrostatic bearing and is especially ideal for precision work. It features high speed no friction between metals, no heat generation deformation-free producing extra high accuracy for continual use.
Advanced hydrostatic lubrication system for the slideways of the table and wheel head lubricate the ways with an automatic lubrication system to provide extremely smooth movement and superior grinding accuracy.
The optional internal grinding attachment allows the operator to grind inside tubing or bearing races quickly and easily.
