Dressing Diamond Aligning Tool

A dial micrometer identifies the center line of the radius of a dressing diamond for alignment with a head grinding wheel.

A magnetic read/write head surface contour is shaped by the complementary contour of a grinding wheel. Repeated use of the same wheel requires that the wheel be dressed to restore its accuracy. This is accomplished with a dressing diamond mounted in a holder attached to a controlled-motion dressing arm.

It is essential that the diamond be replaced in exactly the same position relative to the tape head surface contour during dressing operations. This is accomplished away from the grinder by aligning the diamond, with respect to the base, while the base is mounted on a pedestal. A dial micrometer fixed to a rotatable sweep arm indicates when the diamond's radius is exactly aligned with a line through the sweep-arm pivot. Since the base has a fixed position relative to both the pedestal and the grinder pivot arm, alignment of the diamond high point assures repeatable wheel dressing.

A micrometer reading of zero at both ends of the sweep indicates proper alignment of the diamond and holder in the base.
