One of the two Miyano Citizen Swiss screw machines is dedicated solely to this hand grip used in exercise equipment while the other runs every other Swiss job.
15,000 RPM Spindle, X=30 in., Y=20 in., Z=20 in., and a 40-tool changer. “The UMC750ss outdoes everything we had hoped it would do,” touts Jon. “The aerospace part on it right now is similar to ones we’ve done before. Our programmer/operator really pushes himself to keep improving processes to make better parts faster. Honestly, we struggled in the beginning to achieve true 5 axis simultaneous machining. We went back to Haas, and to Gibbs, looked everywhere for a solution. Once we got the answer, everything opened up for us. We do so much
more with it today than we did even 6 months ago. Our success with the UMC has been so great that we are only investing in higher complexity machine tools right now.”
Since purchasing the UMC750ss, M&M has added a 5th axis trunnion to one of their new VF3 machines and acquired a new 4 axis HRT210 rotary. They’ve also expanded with a second Miyano Citizen BNA-42MSY dual spindle Swiss turning center and a Hwacheon High- Tech 230CL, both with dual spindles and live tooling. “We sat down and looked at what we had capability wise
and what we were missing,” explains Jon. “We have 3 axis and 5 axis so a dedicated 4 axis machine seemed logical. Combine that with the 5th axis trunnion and 70% of the parts we run on the UMC can also be run on one of those two machines. Only the larger and more complex parts need to be run on the UMC. We’ve been able to take on a lot more 5 axis work because of it.”
The 5 axis is also directly responsible for M&M’s latest lathe as well. Already familiar with complex turning work from their Swiss experience, M&M knew the time to foray into a larger live tooling lathe was a top priority. “We purchased a Hwacheon Hi-Tech 230CL from Selway and honestly we are nowhere near reaching the potential of that machine,” tells Jon. “It has a 10” chuck, good horsepower, sub- spindle, Y axis, 24 tools and everything you could ask for, but we are sneaking up on setting it loose. Slowly we are reprogramming jobs to match the capabilities
