WTC Trunnion Assembly

The WTC series creates a Trunnion Assembly from an ATC unit and counter-bearings mounted on a base plate.

A range of counter bearings are available to match the ATC sizes and the selected counter-bearing determines the length of the fixture plate. Alternatively, the ATC faceplate and counter-bearing can be replaced by a check plate.

Custom assemblies can be designed and manufactured by Brown and Holmes to suit your specific machine tool application.
