Thinking about synchronous tapping to reduce CNC cycle time?

One of the most common methods of tapping in use today on CNC machines is “rigid tapping” or “synchronous feed tapping.” A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory, a solid holder without any tension-compression can be used.

However the problem with this is that in actual practice it is impossible for the machine to exactly match the pitch of the specific tap being used. There is always a slight discrepancy between what the machine is doing and the actual pitch of the tap. If a solid holder is used, this discrepancy is detrimental to tap life and thread quality because extra axial forces are exacted on the tap.

The Mega Synchro Tapping Holders from Big Kaiser feature a unique mechanism to compensate for synchronization errors during rigid tapping. 

The special feature absorbs the pitch difference between the tap and spindle, which exorbitantly reduces the thrust loads on the tap and workpiece. This stretches tool life, and improves overall thread quality...up to 90%. Mega Synchro comes in a wide variation of 47 bodies and 258 tap holders. The various combinations of body and tap holder offers ideal projection lengths for any machine

The Mega Synchro Tapping Holders will provide you with the variety necessary to create ideal projection lengths from job-to-job and reduce those problematic bottlenecks in your CNC cycle time.
