THRUVAR 8 - ID GAUGE HEAD FOR GRINDERS

The Thruvar 8 gage mounted inside the workhead spindle measures plunge ground workpiece internal diameters (ID). allowing easy access for workpiece load/unload. The gage features a Quick setup mechanism to reduce setup time to less than 30 seconds. also minimizing part changeover costs.

The Thruvar 8 measures workpiece inner diameter as the part is ground. and the measurement of workpiece size is monitored in realtime. The relay outputs are used to control wheelslide infeed for improved part size and finish consistency. Improved size control translates into improved gr inder productivity and reduced direct labor.

The gage consists of a housing with two exterior gaging fingers attached to shaf ts extending from the inside of the housing. Tension arms inside the housing are attached to the shafts with soft metal clutches. Gaging finger movement is transmitted through the shafts to the interior tension arms.

The shafts are mounted on pre-lubricated ball bearings, and are double sealed where they pass through the case. All parts inside the gage, except the clutch, are either stainless steel or aluminum to minimize corrosion due to condensation.

The gage also includes three finger retraction settings with a fine adjustment feature.
