BIG Kaiser's 319 SW series is a rigid, new style, twin cutter rough boring system. These corrosion-resistant boring heads offer a unique feature by simply reversing the insert holders users can switch between balanced and stepped cutting. The Kaiser 319 SW series will replace the older 314 RW series.
By not introducing additional components or having to manually adjust insert height for different roughing methods, the 319 series reduces setup time and eliminates the need for a presetter due to fixed tool heights and a diameter scale on the tool.
"These tools are fully compatible with our existing KAB and CKN modular systems and offer much larger variety, versatility and capability to our rough boring program." says Jack Burley, BIG Kaiser vice president of sales and engineering. "Although the current 314 series will be phased out, our customers will maintain the same roughing methods from one head using the 319 program, but now with greater ease of setup and higher performance."
The tools, with a diameter range .787"-8.000", utilize standard carbide inserts (CC, SC, and SP) and provide coolant-through direct to the cutting edge to improve chip evacuation and lengthen tool life.
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
A new deep-hole microdrill from BIG Kaiser's Sphinx line provides a time-saving option for creating wire EDM starter holes, averaging 5X faster per hole according to testing.
