The company reports that its SynchroFlex can increase tap life by as much as 100 percent. The tap driver uses a customized precisely-machined, steel alloy, double flexure between the mount and the chuck. This compensates axially and radially for the unavoidable discrepancies between the machine’s programmed rpm, feed and traverse, as well as the exact thread pitch and precise hole location, the company says. Discrepancies cause extra wear on taps, and the SynchroFlex allows the tap to reproduce itself exactly under the sole influence of rotation.
SFT tapping units are available with a range of shanks, capacities and tapping holding systems, and with or without coolant-through to adapt to various applications.
