Boring tool system supports spindle speeds up to 6,600 SFM

Big Kaiser has introduced the new, large-diameter Kaiser 318 series, a complete tooling system supporting aluminum and steel components for twin-cutter rough boring, precision finish boring, and precision OD turning operations.

The system bores from 7.87 to 13.39 in. OD for ISO40/HSK-A63 tapers, and 7.87 to 24.41 in. OD for ISO50/HSK-A100 and larger tapers. Special components allow the system to extend up to 118 in. OD. The mounting flanges feature the company’s new CKN modular connection with a three-screw interface, developed for high-torque transmission with lightweight tools.

The system supports spindle speeds up to 6,600 SFM. The high-strength aluminum components are hard-coated to protect against wear and corrosion, and all assemblies deliver high-pressure coolant through the tools to cutting edges.

The series features aluminum extension slides that allow for diameter- and length-setting adjustments without a tool presetter.
