Running at 4,800 RPM with a feed rate of 10 IPM, they were getting 10 passes per part and producing 10,000 parts per year. The end mill had a 0.015” corner radius, slotting at 0.0625” depth of cut per pass. At the time, they were using a traditional 5/16” diameter, 4-flute TiAlN coated end mill from a competitor. The 15-5 stainless aircraft part required a 4” long slot at 0.587” deep. Recently, one of my customers from Minneapolis, MN was running into some issues with a part they were machining. Unlike traditional geometry end mills that have a difficult time with harmonics and chip removal, the unique 4-flute variable helix design of this UVX end mill allows for chatter-free milling and facilitates excellent chip evacuation, leading to improved tool life. One such innovation is the EXOPRO ® UVX-SUS End Mill, designed for maximum metal removal rates in stainless steel, titanium and high nickel alloys.

Meghan also enjoys drawing natural landscapes as well, finding it has a calming effect, but her other true passion is animals. “It’s our favorite hobby in the fall months as the leaves turn to brilliant colors of yellow, orange, red and purple.” We have tried anything in between S3555 and S300, thinking that might help.Having been with OSG 2 ½ years now, Meghan has learned a great deal from her previous experience in customer service and her participation in continuous training classes offered by OSG.īut when Meghan is not exercising her mind at work, she enjoys small weekend getaways with her husband, especially anything involving the great outdoors.įrom horseback riding to long walks and bike rides through the forest preserves of DuPage, Cook and Lake Counties, she delights in the fresh air and tranquility that comes from being one with nature. The recommended RPM for a Balax M2 is S3555. The speeds and feeds in this code are generic. So it is not just that individual mill that can't tap. Additionally, most of the parts have M3 STI holes in them that we cut tap. These parts run in multiple locations throughout the shop. Some have may six M3 holes, some may have fifty eight M2 holes and eighteen M2.5 holes. This is a package of parts that gets assembled by our customer. So the breakage is likely related to the tap diameter. As the taps increase in size, the tap breakage is less often. Mostly we cut tap or thread mill on parts for other customers. M2, M2.5, and M3 are the only 3 form taps we are struggling with for this customer. Thanks everyone! A lot of great stuff here! Any help or advise would be appreciated, Thanks Maybe there's something I just don't know about. Maybe there's something simple that I just haven't thought of. And some other off-brand, thick as molasses, tapping compound. We've tried Tap Magic for aluminum - comes in a red/white spray can and is supposed to be cinnamon scented. I'm not a fan of the coolant, but there's no getting away from it. The coolant we use is a local brand I think, AFT (Advanced Fluid Technology) 619M2. We have purchased an Emuge Softsynchro high performance tap holder. Probably another 5 or 6 brands that I can't remember.
