Vibration-Free Solution for Deep-Hole Boring

Ultimate solution for overcoming tool overhang challenges of up to L/D = 14

Applications & Features

Internal turning

1. Vibration Dampening Mechanism

When cutting forces create vibration on a boring bar set up with long overhangs, the bar’s dampening mechanism counters the tools motion and cancels the vibration. The dampening mechanism consists of a weight supported by spring elements. The vibrations die out quickly eliminating noise and chatter marks.

2. BoreMeister head

BoreMeister is comprised of the anti-vibration bar and interchangeable boring head, featuring serrated interfaces for high precision indexing. They are connected by screws, allowing the fitting of a wide range of cutting heads for increased flexibility.
