2 icense Unique feature to compensate for synchronization errors. Improves threa quality an tool life by reucing thrust loas cause by synchronization errors up to 90%. MGT Set Screw Working Principle of Error Compensation Unique feature absorbs the pitch ifference between the tap an spinle when using rigi tapping cycle to minimize thrust loas. Wie Variation of 41 Boies an 45 s Various combinations of tool an offers ieal projection lengths for any machine. Secure Drive an are fixe with a rive key in the rotation irection as well as the square of the tap.

Coolant Through Center Capability for All Moels Coolant is supplie both through the tool an to the tool periphery simultaneously.

4 compensates for synchronization error. Synchronization errors still exist with rigi tapping. A small gap is cause by the timing uring the change between forwar an reverse spinle rotation an the fee irection from minus to plus. In aition, pitch tolerances on the tap also cause error. Some taps have stronger cutting resistance epening on the shape. BIG Mega Synchro compensates for synchronization errors with any type of tap. Minimize thrust loa to both the tap an workpiece improves threa quality an tap life. oa to Tap Measure by Kistler ynamometer Spiral Tap AU1/4-20 N=1,000 RPM Twiste grooves on a spiral tap cause loaing in the reverse irection, similar to an en mill. Thrust oa (lbs.) Time (sec) Approx lbs Collet Chuck Approx lbs BIG Mega Synchro forwar stop reverse BIG Mega Synchro reuces force loa to approx lbs. This is less than 1/10th of the loa compare to a collet chuck. Approx. 165 lbs of reversal force loa is applie to a tap hel with a collet chuck. Point Tap AU1/4-20 N=1,000 RPM Roll Tap No.2-56 N=3,000 RPM Thrust oa (lbs) Approx. 66 lbs Collet Chuck Approx. 4.4 lbs BIG Mega Synchro forwar stop reverse Time (sec) Thrust oa (lbs) Collet Chuck Approx lbs Approx. 6.6 lbs BIG Mega Synchro forwar stop reverse Time (sec) Thrust loa is cause in both the forwar an reverse irections with a point tap, while a spiral tap has only reversal forces. However, BIG Mega Synchro minimizes thrust loas in both irections. Thrust loa in the forwar irection is continuously applie to a roll tap, reaching its peak at the moment when rotation is change to reverse. BIG Mega Synchro eliminates the loa effectively. 3

5 Variation in oa Between Machines Synchronization performance, tap loa an cycle time will vary between machines. BIG Mega Synchro minimizes the thrust loa, even with machine builer A which has the largest thrust loa. Machine A + Collet Chuck Machine B + Collet Chuck Approx. 108 lbs Approx. 143 lbs Spiral Tap AU1/2-13 N=500 RPM Machine C + Collet Chuck Approx. 66 lbs Machine A + BIG Mega Synchro Approx. 18 lbs oa in Tension (lbs) Spiral Tapping with Coolant Through Slits BIG Mega Synchro is capable of supplying coolant through slits to the tap periphery. High pressure coolant up to 1,000 PSI is possible with no effect on the minimize loa to the tap. Spiral Tap AU1/4-20 N=1,000 RPM Point Coolant is supplie to the Tap Holer in a raial irection at 2 symmetrical positions. This allows for the to be free from the axial pressure of the coolant. BIG Mega Synchro External coolant supply = Coolant from nozzles on machine spinle flange. Collet Chuck + external coolant supply Approx. 88 lbs BIG Mega Synchro + external coolant supply Approx. 6.6 lbs BIG Mega Synchro + internal coolant supply through slits 1,000 PSI Approx. 8.8 lbs oa in Tension (lbs) Comparison of Surface Finish Tapping of exotic materials tens to cause a compresse burr on the threa surface. BIG Mega Synchro compensates for synchronization errors an minimizes cutting loa. Fine surface finish of threas is achieve. Spiral Tap No Material: 4130 Collet Chuck BIG Mega Synchro 4
