Big Kaiser has added the Dyna Contact to its product offering. The ceramic taper gage enables at-a-glance inspection of machine spindle tapers. 

Dyna Contact is a precise gage used to check the geometric accuracy of a machine spindle taper by visually comparing the contact of the gage to the spindle. A layout dye is applied to the Dyna Contact before inserting into the machine spindle. Upon removal, an operator can check for taper contact and determine if the machine spindle will have proper contact with toolholders. The product is compatible with all steep taper specifications, including CAT, BT and DIN.

The ceramic material of the Dyna Contact makes it more thermally stable than steel. It is also rustproof, 10 times more wear resistant than steel and not subject to age deterioration, according to the company. 


  • Measuring Part Geometry On The Shop Floor

    Measuring workpiece dimensions is relatively simple for machine operators but measuring workpiece geometry which involves more complex comparisons of part shape to an ideal shape--is now also practical on the shop floor. The gaging equipment for doing this is coming down in price while becoming easier to use.

  • Standardizing The Measurement Process To Find The Right Gage

    Guidelines used to standardize the measuring process can provide a good basis for making gage decisions.

  • Surface Finish: A Machinist's Tool. A Design Necessity.

    Simple "roughness" measurements remain useful in the increasingly stringent world of surface finish specifications. Here's a look at why surface measurement is important and how to use sophisticated portable gages to perform inspections on the shop floor.
