In profile and round rails, however, the bearings ride on the guide rail and are exposed to any of the contaminants that may settle on the rail. The bearings in a 90° double-vee guide wheel are self-contained and isolated from the environment, so there is no contact between the bearings and the rail.

A double-head grinding machine includes: a spindle driving portion configured to rotate a spindle to which a grinding wheel is attachable; a moving portion configured to move the spindle driving portions toward and away from a wafer; and an inclination measuring portion configured to measure a change in an inclination of the spindle in association with a movement of the spindle driving portions.

Now, the new Guide Rails have a track for the new Carriage System wheels to ride along to ensure a smoother, more precision motion. Due to this, the Guide Rails are not only used for cutting …

A linear guide (or linear bearing) is a mechanical element that allows relative motion between two surfaces, with one surface supporting the other, and minimum friction between the two. There are two basic types of linear guides: plain and rolling element. While their general function is the same, their design and performance differ significantly.
