"Now our in-house costs compare favorably with those of offshore suppliers on a larger percentage of the molds we make," Hunt says. "The more we can economically do here in Ontario, the better we can serve our customers." info@cumsausa.com www.cumsa.com From the original Sprung Core to the most advance double rack, CUMSA vertical lifters offer a variety of solutions to resolve your particular job.

A trial on a hardened P20 mold component several weeks later confirmed Poirier's suspicions. Speeds and cutting depths were left unchanged, but the tool ran at 300 ipm—twice the previous feed rate. The process ran quietly, chips came off smoothly, and the as-machined surfaces looked just as good after three hours as they did after six hours with the previous face mill. Reko and Ingersoll then repeated the test at the same parameters, but on soft tooling. Throughput tripled, and projected tool life improved to 10 hours in the cut, compared with only 4 hours before. What's more, during both trials, Hunt noticed that spindle load dropped from 60 percent to 20 percent, despite doubling the material-removal rate. "Now that's free cutting," he says, crediting the smoother, slicker IN 4030 coating for the improvement. Finally, just as he did with the new tooling on the five-axis machine, he verified that the Hi-QuadF would outperform other, similar tools prior to committing. More Than Meets the Eye "These two applications show two things about high-feed tooling," Poirier says. "In the semifinishing case, we see that there are real performance differ- ences, even though both tools were clas- sified 'high-feed.' In the roughing case, a nominally high-feed tool improved a standard-feed application. All high-feed tools are definitely not the same." Reko has leveraged both improve- ments to offer tighter delivery sched- FOR MORE INFORMATION: Ingersoll Cutting Tools / 815-387-6600 / ingersoll-imc.com Reko International Group / 519-727-3287 / rekointl.com VIDEO: Close Footage of the High-QuadF in Action short.moldmakingtechnology.com/highqf
