Recent additions to the Big Kaiser Precision Tooling Inc. digital boring head options cover the middle range and large diameter range—meaning the company now offers a digital boring head to cover the full spectrum of finish boring sizes and series.
All of these digital heads were designed geometrically similar to their analog predecessors—same range, roundness, shape and height—so the user can swap an analog for a digital model without any reprogramming. Also, existing Kaiser accessories such as shanks, extensions, reductions, slides, boring bars and insert holders are compatible with the new digital tools.
Additional features shared across the entire digital lineup include an IP 69K seal rating (highest possible) and a coated body to assure complete resistance to contamination and corrosion. For ease of use, a single button is all that is needed to operate the digital readout and the large, high-contrast display relates diameter corrections with a resolution of .00005"/Ø, or .001mm/Ø on metric heads. The tool carrier's measuring system shows the effective movement of the cutting edge and permits diameter corrections in both directions.
Kaiser Series 310 EWD Precision Finish Digital Boring Heads use existing insert holders from program 310 EWN to allow maximum boring range per head and compatibility with existing special design insert holders. Five heads cover the range of Ø1.614”–8.000”, feature through-spindle coolant capability with directional coolant ports, and can perform back boring operations by simply reversing the insert holder.
The accuracy of a digital display is also now available on the Kaiser Series 318 Large Diameter Finish Boring System. The lightweight system is based on aluminum extension slides to support a variety of aluminum, and some steel, components. The series also features through-tool coolant supply to the cutting edge, for optimum chip making and breaking.
