roughing boring head / large-diameter

The 317 boring system is designed for heavy roughing of bores from 5.91" to 46.46". The compact rugged configuration makes it ideally suited for use on production machines such as boring mills and machining centers with spindle taper sizes of 40 and larger.

The 317 system consists of a small number of modular components, including a flange, extension slides, and high precision dual insert holders. Most components are universally utilized with the specific bore diameter being dependent only on the selection of the appropriate slide. Each extension slide has an adjustment range of over 2.75" in diameter.

The 318 boring system is designed for heavy roughing of bores from 7.87" to 24.41" with standard components, and up to 118" with special adapters. The lightweight and secure "pinned-to-fit" configuration makes it ideally suited for higher speed operations-up to 6600 SFM! For use on production machines such as boring mills and machining centers with spindle taper sizes of 40 and larger.

The 318 roughing system consists of a small number of modular components, including a steel flange, aluminum extension slides and clamping bases, and steel insert holders. Most components are universally utilized with the specific bore diameter being dependent only on the selection of the appropriate slide. Each extension slide has an adjustment range of over 2.75" in diameter.
