THRUVAR™ 8

IN-PROCESS GAUGE FOR ID GRINDERS WITH MANUAL QUICK SET-UP

The Thruvar 8 Thru-Spindle Gage measures plunge ground workpiece ID’s. The Thruvar 8 gage is mounted inside the workhead spindle, allowing easy access for workpiece time measurement of workpiece load/unload.
The gage has a patented slip-clutch mechanism to cut gage setup time to less than 60 seconds.
Quick setup also minimises costly part changeover cost.
The Thruvar 8 measures workpiece inner diameter as the part is ground. The gage signals are processed by a gaging monitor and relay outputs are sent to the grinder based on real size. Feedback I/O's are used to control wheelslide infeed for improved part size and finish consistency. Improved size control translates into improved grinder productivity and reduced direct labour.
The gage consists of a housing with two exterior gauging fingers attached to shafts extending from the inside of the housing. Tension arms inside the housing are attached to the shafts with soft metal clutches. Gauging 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 aluminium to minimise corrosion due to condensation. The gage includes three finger retraction settings with a fine adjustment feature.


This measuring head is to be connected to P7 or P7ME or  P3ME  electronic units.
