Large Diameter Finish Boring

Series 318

Boring Range: Ø7.795" - 118"

The 318 large diameter boring system is designed for precision finishing of bores from 7.795" to 24.488" - and a special adapter can extend the system up to 118". The lightweight and secure 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 finishing system consists of a small number of modular components, including a steel flange, aluminum extension slides, aluminum counter-weight, aluminum precision boring head and a steel insert holder. 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.

Large Diameter Finish Boring

System 318 for Finish Boring

This super light system provides highest precision and performance, and features through-tool coolant supply to the cutting edge. The mounting components are "pinned to fit" onto specific locations on the slides, and secured with steel bolts. The precise positioning of the components on the slide along with incremental adjustment scales for insert holders permit diameter and length setting without a tool presetter.

The 318 system utilizes the new KAISER CKN modular connection.

EWD 200 digital option now available for the entire range of Ø7.795"-118.150". All 318 components remain the same when switching out the analog head for digital option.

 318 XL for Finish Boring

Five aluminum bridges and five sets of extension slides can be combined in different configurations to offer boring assemblies for the range of ø24.47"-118.15". Rough boring clamp bases and insert holders, as well as finish boring heads and counterweights, are used from the light weight boring system Series 318. Optional coolant pipes offer through-tool coolant supply directly to the cutting edge.

Available for the entire range of ø24.47"-118.15"
