    It's out there but your not going to find it working as an employee. Whenever talking with a prospective or new customer I would always ask for their problem parts. Often their "problem" parts really...

    Compared to ER collets my indicator disagrees with you. Same diameter tools measured on the shank, .0002"-.0003" tir for the collets, .0002"-.0004" for the side locks. All tools torqued to maximum...

    In the first window of the toolpath creation box, you can choose local or system tools so you can limit how those tool paths update with tool modifications. This may or may not be what you are asking...

    I started out doing plastic injection molds and product development and now only do simple aluminum parts, mostly skim all sides of a rectangle. The simpler my work got the more money I made. Granted...

    It's hard to beat the flexibility of a 6 axis robot. While I have a fixed table mill just sitting, I haven't turned it on in 7 months since its dedicated product line died from Covid, I am going to...

    Shimming the blocks is pretty standard procedure and nothing to be concerned about IMO. Since you are using linear rails and blocks vs box ways it's not really any more of a compromise. I have...

    Personally I don't like the stone I use on my table or vises to be clean and sharp. I like it to be glazed and clogged so I don't remove any metal checking for nicks. If I do find a nick I then flip...

    Pacific Machinery and Tool Steel in Portland Oregon might be worth a try. I have bought cut pieces of A2 from them and had it shipped a few times. The last was 2" diameter x 3/4" long, around 30pcs....

    You really need the Matsuura manuals too as a lot has to do with how the control was integrated. Does your mill have a JCP05 card in the cabinet? This would be for the high speed machining option,...

    The tool in the spindle isn't good but other than being hard on the bellevilles it shouldn't be a problem, as long as it comes out.

    The bad washers came out in pieces. They probably started...

    Nope, crashes were extremely rare. If there were I would know it since I made all the fixtures. Most of the time the stub 1/4" mill was the biggest tool being pushed hard and I used a 3/4" mill as a...

    I use a 1/4" gage pin, broken end mill shank, to touch off my tools, and have done many .005"-.02" end mills with no problems. Start low and raise the tool .0001" at a time until the pin just rolls...

    It depends on what you consider "contaminate" means. Short of removing the coolant and a full wash after the organics there will be some contamination.

    IME the Harvey aluminum specific 5 fluters don't really leave any better finish than 3 flute Destiny Vipers run at the same feeds and speeds, but they are way stiffer when cutting deep! I also have...

    Loctite would be my pick, something like 263 or equivalent.

    On second thought it depends on the fit, 263 likes a .003" gap. If it is much closer then go with a thread locker for press fits.

    Say maybe 8 ounces of concentrate for every 20-30 gallons of makeup, at most. I use Trim C320 which is a full synthetic at 7.5% +/-.5% checked every few days with a refractometer.

    Since you are rotating the part to drill a hole it will naturally seek to center the tool. It sounds to me that your tailstock is not centered to your spindle.

    I see no problems with what you are wanting to do. My only reservation would be the extra time it will take if your tools are not next to each other.

    The anodizers will not want your parts to be oily, no need to ask. If you have this much oil in your coolant you need to deal with it.

    Here is some interesting info on Simple Green, it's their FAQ...

    North of 95% of the "granites" at countertop shops is not granite, not enough quartz. You will have better luck at a monument shop. If it were me I would just cut up a surface plate for parallels,...

    Well there you go! Stick some scraps in your Simple Green for awhile and you will see why it's a bad idea. First keep the oil out of your coolant, the less oil in your coolant the easier it is to...

    I started rinsing my chips with the water I use to rinse my parts off a couple of years ago. I hardly add coolant concentrate anymore, it's made a huge difference.

    Keep the ones you don't use and get more of the ones you do. Once you get rid of the odd balls you will immediately need them, Murphy's law.
