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. Accessory insert holders allow the system to perform face grooving.

Please note: We have decided to change our tool connection description of KA/KAB to CK/CKB to be consistent with how the product is referred to globally. There is absolutely zero geometric difference between a tool marked KA/KAB and CK/CKB, it was simply a way to differentiate North American inch tools from metric tools sold throughout the rest of the world.

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 BIG 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.
