Big Kaiser has introduced the new, large diameter Kaiser 318 Series-a complete tooling system supporting a variety of aluminum and steel components optimized for twin cutter rough boring, precision finish boring and precision OD turning operations. The new series features a standard boring range of Ø7.87"-13.39" for ISO40/HSK-A63 tapers, and Ø7.87"-24.41" for ISO50/HSK-A100 and larger tapers. Special components allow the system to extend up to Ø118". The mounting flanges feature Kaiser's new CKN modular connection with a 3-screw interface, developed for high torque transmission with light weight tools. The system supports spindle speeds of up to 6,600 SFM thanks to safe and secure "pinned to fit" light weight aluminum mounting components. 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 318 series features aluminum extension slides that allow for diameter and length setting adjustments without a tool presetter," says Jack Burley, Big Kaiser vice president of sales and engineering. "The simplicity of this system virtually eliminates operator error during assembly and promotes safety during operation."
