Are you using a synchronous feed mechanism and a float type tapper at the same time?

Even if the machine adjusts the pitch of one revolution, the Tupperware will float due to the load during machining, and the feed of the tap will be shifted.

When tapping with equipment with a synchronous feed mechanism, a direct chuck that does not float or

Consider using a dedicated tap holder for equipment with a synchronous feed mechanism that is adjusted to a small amount of float that does not interfere with synchronous feeding.

OSG offers a maintenance-free and long- tool life tap holder "Synchro Master" for equipment with a synchronous feed mechanism.

It is an excellent match for A-taps, which can be used in a wide range of ways, and can aim for stable tool life of the length of the tap and the stability of the twisting length.
