Dyna Contact gauge from Big Kaiser inspects machine spindle tapers

BIG Kaiser Precision Tooling Inc. has developed the Dyna Contact ceramic taper gauge, which allows inspection of machine spindle tapers at a glance.

This precise gauge is used to check the geometric accuracy of a machine spindle taper by visually comparing the contact of the gauge to the spindle. A layout dye is applied to the gauge before it is inserted into the machine spindle. Upon removal, the operator can easily check for taper contact and determine if the machine spindle will have proper contact with the toolholders.

It is compatible with all steep taper specifications, including CAT, BT, and DIN.

The ceramic material of its construction makes it more thermally stable than steel, the company states. This taper gauge is also rustproof.
