Perje made this gage from scratch and used it while grinding the parts to within .000,050"

Our new face gear attachment shown can mount, among other things, a dressing diamond directly to the side...

Another demonstration of the Newbould face gear repeatability using the Wireone tilt setup.

Repeatability is critical in our industry, and we provide it.

As smooth and accurate my air spindles are, they are also strong and easy to service. Made entirely of stainless steel, and shop tough. This movie was made with 80 to 90 lbs PSI of air pressure to ...

Using a sensitive indicator graduated in 20 millionths inch increments (0,0005 mm) there is no discernible variation in the faceplate runout.

I.D. grinding on a Newbould workholding air spindle. The rotation is driven by the grinding wheel. A drive motor on the workholding spindle is not needed.

When locked by air pressure, the Newbould air spindle is solid enough for many types of milling. In this video, I'm milling a hardened stainless steel rotor.

My wife's slightest touch makes their heads spin.. :O)
