THE TRI-MOUNT TM BALL BAR COLLAR IS AN IMPROVEMENT IN THE TOOLS FOR COORDINATE MEASURING MACHINE EVALUATION. THE FUNDAMENTAL DESIGN OF THE TRI-MOUNT ALLOWS IT TO HOLD THREE OR MORE SEPARATE BALL BARS ALL AT THE SAME TIME.

IT IS MACHINED TO FORM A COLLAR THAT WRAPS AROUND THE VERTICAL POST OF THE STAND. A SLOT IS USED TO LOCK THIS REAR BLOCK IN PLACE.

IT IS CAPABLE OF HOLDING AS MANY AS THREE BALL BAR CLAMPS AT THE SAME TIME, ALSO REFERRED TO AS THE FRONT BLOCKS. USING THREE DOUBLE BALL BAR CLAMPS, THE TRIMOUNT COULD POTENTIALLY HOLD AS MANY AS SIX BALL BARS.

WITH ONE BALL BAR HELD VERTICAL, ONE HELD HORIZONTAL AND ONE HELD AT AN ANGLE, ALL OF THE TWENTY POSITIONS SPECIFIED IN THE ANSI B89.4.1-1997 STANDARD CAN BE ACHIEVED. A UNIQUE FEATURE OF THIS NEW DEVICE IS THAT IT TOTALLY ELIMINATES ANY HAND CONTACT WITH THE BALL BAR (DUMBBELL) BY THE CALIBRATION TECHNICIAN. THIS IS ESPECIALLY IMPORTANT BECAUSE ALL BALL BARS ARE RATHER LONG DEVICES WHICH MAKE THEM VERY SENSITIVE TO TEMPERATURE CHANGE.

THE LOCATION PORTS ON THE TRI-MOUNT WILL ACCEPT THE SINGLE BALL BAR CLAMP (PART #FS-1BB), THE DUAL BALL BAR CLAMP (PART # FS-2BB), THE SMALL BALL BAR CLAMP, (PART #FS-1BB-S) OR ANY LENGTH OF THE WAY OUT BALL BAR SUPPORTS.
