ELK GROVE VILLAGE, IL—A comprehensive overview of the new EWB-AL aluminum tooling system is now available in catalog form from BIG Kaiser Precision Tooling Inc.

The four-page color catalog provides in-depth specifications for forward and back bore applications, lists the complete line of available extension and reduction adaptors, and offers users thorough information on large diameter flanges and extension slides.

The catalog includes the new EWB-AL auto-balance boring heads, requiring only two different heads to cover the entire diameter range from 3.937" to 8.000", is designed for cutting speeds up to 6,600 SFM. The system offers simultaneous clamping of adjusting cartridge and counterweight to ensure precision accuracy and safe operation at high speeds.

EWB-AL heads, extensions, reductions, and large diameter extension slides are made of high tensile aluminum with hard coating, resulting in a tool weight 1/3 that of steel, and are equipped with a highly accurate self-balancing mechanism. Combined with reductions and extensions made from the same material, tool weight for long and large diameter tool combinations is reduced by more than 50%, eliminating weight problems during automatic tool changing (ATC).

EWB heads are designed for precision boring on modern CNC machining centers, allowing users to perform forward and back boring operations without the need for additional components. They feature micrometric adjustment precision, with dials graduated in increments of .0005 inches. The dial’s design allows for precision adjustments to be made at the machine.

A high precision Vernier scale permits more accurate setting accuracy to .0001"/diameter. Precision balancing occurs automatically with adjustment of the diameter.
