    Has Anyone Had Luck With Staffing Agencies?

    That’s a lot harder to do with the current state of the industry. Many coffee shops pay $20/hr plus tips for slinging coffee, enjoying the air conditioning, talking to women, and coming home smelling like Java. Hard to get somebody to leave that for a couple more bucks an hour (maybe), and the...

    Seemingly Impossible task, Any Tips?

    In 6061 you don’t even have to neck the tool back. It will burnish the top of the hole, but unless the runout is really bad should not hurt anything. Just have to find a tool that’s long enough. Usually I can source something off the shelf, or cobble it together with an exchangeable head on a...

    Seemingly Impossible task, Any Tips?

    We interpolate 15XD at +/-.0005 all the time in aluminum. Just takes a while. Getting the chips out is the hardest part. I try to leave only a few thou on the walls after drilling. Have gone up to 20XD on interpolated holes, which sucks, but is do-able. Finding endmills becomes challenging...

    Seemingly Impossible task, Any Tips?

    Drill close to size and interpolate with a .625 end mill. Takes forever, but works. That stick out is rough, but not crazy, esp in 6061. You can also use an ISCAR chamdrill flat bottom, then come back and remove the chamfer by interpolating just at the bottom, staying .001in off the walls. My...

    HSK63A endmill holders

    I don’t use sidelocks for endmills in the HSK machines. Never have. We do have a couple sets of HSK63 sidelocks for all the other potential uses though - drills, fans, brushes, saws, indexables… They see a ton of use even if zero endmills go in them.

    Modular Endmill Extension (screw on head) Brand Compatibility

    Gregor - I get it. I was asking about both styles at the same time. My confusion stemmed from the fact that our ISCAR bodies see a lot of use (including indexables from ISCAR that are a multimaster interface). Our ISCAR bodies do fit Ingersoll (which we have), and I thought they fit Sandvik...

    Modular Endmill Extension (screw on head) Brand Compatibility

    Yes. It was a Mits indexable head that started my confusion. We mix and match brands of solid carbide heads with some frequency, and I never give it any special consideration. Almost everything we have here is compatible with the multimaster. I've gotten so used to it, that I was surprised...

    Modular Endmill Extension (screw on head) Brand Compatibility

    Thank you! This is probably the same list I saw a few years ago, but couldn’t find last night. Very helpful! Looks like with Iscar the options are multimaster or flexfit, with the latter being the standard shown in the Maritool document. I found an Ingersol shank that is exactly what we...

    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...

    What's my worth?

    LOL - Where do you get this?! Their wages are publicly available and listed on job postings... This is the Washington/Oregon pay scale for hourly. Machinists are normally grade 8 or 9... https://www.iam751.org/?zone=/unionactive/private_view_article.cfm&HomeID=452936&page=Information

    When does NET30 start?

    The problem is the big customers are gonna pay at NET30, and then take the 10% discount anyways. Good luck beating that extra payment out of them, because they have all the leverage, and the offsite AP team is never going to pickup the phone.

    15K Spindle Warmup Dilemma

    This topic frequently gets beat to death. I don’t understand why so many folks find it impossible to just look in the manual for their machine, and run the warmup procedure as specified by the manufacturer. Not all spindles are the same, so there is no one-size-fits all warmup procedure. I...

    What’s going on at Boeing

    Agreed. It is almost entirely driven by Wall Street, because the people in charge of these companies get compensated for stock performance, and not for product performance.

    What’s going on at Boeing

    McDonnel Douglas brought most of the defense work. Before the merger Boeing was pretty focused on passenger jets. They've already parsed out as much commercial manufacturing as possible to Spirit, Triumph, and Warren Buffet's legion of suppliers. It's generally acknowledged that a lack of...

    What’s going on at Boeing

    Muilenburg was an engineer. Shit wasn't Jack Welch an engineer? I'm all for getting technical people in charge instead of money people, but the engineering degree doesn't make them immune from C-Suite shenanigans.

    What’s going on at Boeing

    Seems alarmist to me. Very few engineers are super intimate with the assembly process. Sounds like this guy was a PITA that made problems on one line while he was gawking at the mechanics, and then got moved to another when the assembly crew wouldn't cooperate with him anymore. Fighting gaps...

    When does NET30 start?

    Most of my customers won't start NET30 until the invoice is in their physical or digital possession. So we send the invoice at the same time the pack slip is generated. Most of my customers who are on NET30 pay more like NET45. The ones on NET45 just pay whenever they feel like it...

    Mastercam Automation

    I find a lot of folks struggle with moving from MCAM to Esprit, because you basically have to use features. It's built around feature recognition, and is already doing half of what you want right out of the box. Esprit is not my favorite software for all things, but if I was looking for...

    Have you ever met a machinist that was better than you?

    It was clear to me that by "a machinist that is better" you meant "a machinist that is better at what you do". Otherwise it's entirely subjective.

    2.375in hole in 17-4

    One of the few performance advantages a vertical has over a horizontal or lathe is that they tend to have a lot more z axis thrust, because they have to support the head. The Okuma is a bridge style machine, and the traveling column weighs a lot. Z axis load dropped from 70% at idle, to about...
