    Modular Endmill Extension (screw on head) Brand Compatibility

    Seems the vast majority of exchangeable head endmills we buy fit on the handful of ISCAR Multimaster shanks that we keep in the tool crib here. I recall some time ago seeing a cross compatibility chart that showed there were several brands that were all essentially the same interface, but...

    2.375in hole in 17-4

    I have a stack of 17-4 (A condition) round slugs here. They need a bunch of milling done, but there is a through hole in the center of the part that is 2.5in diameter by 4.5in deep. What's the best way to generate this hole? It's on my Okuma which is ~30HP, 40 taper, dual contact. Right now...

    Mikron UCP 600 - Heidenhain iTNC530 dead pc?

    About an hour ago, the screen on our Mikron just went black, and it e-stopped in the middle of a cut. Machine has been running 24/7 for about a week. No signs of anything out of the ordinary. When I boot the machine, everything looks normal, lights come on, etc... But the main drive shows...

    How to stop Telemarketing at the Business

    Somehow our business landline has gotten locked into the sights of telemarketers, and it has gotten absolutely insane. We easily get 2 telemarketers an hour on average. Anyone successfully combat this? I am thinking perhaps a screener voicemail "press one to speak to sales" type of system...

    Honing Shop

    I've got some really high value parts with a ~2in diameter x 4in length hole that needs to be honed to size. Currently they have TYPE III black anodize that is too thick. Would like to hold +/-.0002 (or better) on the finished diameter. Overall part size is ~ 20 x 5 x 5. QTY 75 Due to cost...

    Spot Treat or Touch Up Hardcoat Anodize?

    Anybody know if it is possible to touch up or spot treat hardcoat anodize? I don't think this can be done, but figured I'd ask the experts over here, and explain my dilemma. We have a stack of really high value parts in inspection ~ 20in x 6in x 6in. 6061 AL. They were bead blasted and then...

    ISO9000 and AS9100

    Anybody have recent experience getting through AS9100 and ISO? We just hired a full time quality guy, and I'd like him to help facilitate the process, but not carry all of the burden. Hoping to get a recommendation for consultants, etc... I was hoping to handle this with our ERP integration...

    Assembly Welding Recommendation for Portland, OR

    Can anybody recommend a good welder in the Portland metro area that can do machined parts? I have some very high value 6061 assemblies that need to be welded together after we do assembly. It's a relatively easy job by my estimation (probably only a few hours total). I'm just a mediocre TIG...

    Solidworks Dropped Online Licensing - Gouging Customers

    SOLIDWORKS Online Licensing Discontinuation So I've ranted on here a few times about how insane it is that our annual maintenance for ~10k in Solidworks seats is about 5k. They are gouging the heck out of customers and offering essentially no improvements or support for the cost of staying...

    Recommendation for large(ish) EDM Work

    Any recommendations for a good WEDM shop that can fit a slightly oversized part? We have a 17inch cube of 6061 that needs an extrusion shape cut all the way through it (+/-.003). The slug left in the middle will be about 90% of the weight. If we can find a way to squeeze this onto an EDM, I...

    Tool Length Measurement on Surface Plate

    So I don't trust the laser on one of our machines, and would like to set tool heights on the granite until we get everything recalibrated. Surely somebody makes an adapter for this? This morning we just dropped the HSK tools on a pair of 1-2-3 blocks. Even a ground block with a big hole in...

    Mikron Service Techs

    Anybody have a good Mikron service tech? West Coast or Pacific Northwest preferred. :D I have always had positive experiences with Ellison, but when I got on their website this afternoon, it appeared like they may no longer be the distributor. :confused: Haven't called around yet. We...

    Source for C110 copper plate

    Anybody have a good source for large(ish) sizes of copper? I'm having a really hard time finding some C110 plate. (Sizes 2.50 and 3.00 inches). We can order it in, but the lead time is 4 weeks, and that won't work for my customer. Surely somebody out there stocks this stuff. Recommendations???

    Finding an Auction (used machines)

    Here's a dumb question. How do I find out about any upcoming auctions on a national level? I'm frantically searching the used market for a Mazak Variaxis, and twice now I've seen machines get scooped up by "local" auction houses. I think I get spam emails from MMI, and it looks like they are...

    Business Insurance

    Who are you folks using right now for business insurance? I have myself plus 3 employees in a 6500sqft leased facility at the edge of Portland. No crazy requirements, but our landlord does have a specific set of criteria for coverages, and we are not currently compliant. I hooked up with...

    Ball Endmill in Aluminum - 3FL vs 2FL

    So I have always been a fan of 3 flute tools in aluminum. They seem to have a little better rigidity than 2 flute, lower chipload at same feeds, plus they can be variable pitch, etc... But when it comes to ball endmills, it's a little harder to find 3 flute tools. In fact, most of the really...

    Metric Cat40 Dual Contact Facemill Arbors

    Just picked up a new ISCAR high feed mill. I love the thing, but it's got a 22mm arbor. ISCAR makes a CAT40 arbor that size, but not with dual contact. Does anybody have a good selection of dual contact CAT40 facemill holders that include metric sizes? I know it's a bit of a goofy...

    Who Makes the Best Corner Rounders?

    Dumb question. Who makes the best corner rounders? We do mostly low quantity parts, and only break out the corner rounders once or twice a year. I'm going to setup a few permanently and add them to the digital tool database, so it's less painfull when we do put them in action. Who's...

    Best Mild Steel for Machinability

    I'm sure it's been asked, but a quick search doesn't return anything. What is the best mild steel for machinability? Specifically we are milling some fixture plates, roughly 1in x 18 x 18. Punching a large hole in the middle, drilling some bolt hole patterns, doing some surfacing, and some...

    Moving to a new Location

    Well, after an insanely long and arduous process, we finally got the keys to the new shop on Friday evening. Covid made dealing with the leasing company (an already ugly process) exponentially more difficult than I ever expected. But it's done now, and we're ready to get to work. We were in...
