BIG Kaiser Precision Tooling’s CKN modular connection utilizes both steel and lightweight aluminum components. The system offers high clamping forces for maximum torque transmission.
Designed for large boring tools, the connection features a three-screw interface between steel double-connector couplings and aluminum extensions. When tightened, the slotted male connector expands to give additional rigidity.
The system offers reduced weight with equal cutting performance compared to tool combinations made solely of steel, the company says. The weight reduction is said to improve machine performance, ease handling and eliminate manual tool changes in many instances. Additionally, the use of multiple materials helps damp tool vibrations.
For large, heavy-duty roughing applications, various components are available for optimized tool assemblies. However, the connection is almost entirely compatible with the existing Kaiser KAB system, the company says. Therefore, existing modular components from the company can be incorporated for lower-torque operations such as finish boring.
A set of donated boring bars that can be used in a 1954 boring head will enable volunteer machinists to recreate a pair of binoculars for the USS Pampanito.
