Air Power Spindle

BIG Kaiser Precision Tooling Inc. (Elk Grove Village, IL) will showcase a number of tooling product lines at Westec.

BIG Kaiser Precision Tooling Inc. (Elk Grove Village, IL) will showcase a number of tooling product lines at Westec. Its air power spindle provides solutions to the endless challenges of micro machining with ultra high speed and precision, offering variable spindle speeds up to 80,000 RPM. The device is an air-driven tool that can be used on existing machining centers to provide dramatic enhancements to surface finish quality, extended tool life, and reduced wear on high speed spindles. Used as an additional spindle on a normal machining center, the device eliminates the need for an expensive, high-speed machine. The device also minimizes thermal displacement in the Z-axis for top precision. When compared with a standard machining center spindle with up to .012mm of displacement, it remains constant at less than .001mm. The micro collet allows a clamping diameter of .018”-.159” and guaranteed runout of less than 1µm (.00004”) at the nose. Also on display will be the new Fullcut Mill FCR, which features extremely sharp cutting edges, with both high radial and axial rake angles, to achieve smooth and quiet end milling in all materials. The sharp cutting edges of this insert retain high strength and toughness due to the optimized eccentric relief angle for each cutter diameter. The cutter is available in diameters 5/8”, 3/4”, 1”, and 1 ¼” in various length configurations with BIG PLUS integral shanks CAT40, BT30, and BT40 as well as HSK-A50 and A63 versions. Also showcased will be the integral-shank design for the EW2-50XL precision finish boring head. The integral design will be available for CAT40, BT40, HSK-A63 and Capto C6 size spindles and provide a shorter tool than the modular shank/boring head combination. In the case of the CAT40 taper, the tool is shorter by more than 1.3 inches. This translates into a lighter and more rigid tool that can operate at higher cutting speeds and feeds. For use with existing center-mounted boring bars (Ø.078”-2.125”) and side-mounted insert holders (Ø3.15”-6.00”), these heads can be used for precision finish boring with a large adjustment dial displaying increments of .0002”/div. and Vernier markings to accurately adjust to .00005” on diameter.
