    The ones designed to hold different shapes of inserts are probably the worst of all...

    The locating surfaces in the pocket get smaller as the number of edges goes up, and when you design it to...

    If surface finish is your primary concern then you should stick to square inserts. They have significantly better insert location repeatability than any of the 8+ sided systems, which means more...

    If you use this vendor otherwise and are happy with their work, then call them directly and explain that your customer is an arsehole, apologise for his behaviour, and promise that you won't send...

    A word of caution about those; I don't have any first hand experience with those particular holders but...

    I use a lot of anti-vibration tools and they are very expensive, so when these appeared...

    I do agree with the rules and efforts to maintain this place as a professional forum. I do agree that hobbyists are better off elsewhere.

    However, there is definitely a sub-demographic who are...

    I have a super cheap and nasty desoldering gun, one of these:

    Typing cam generated programs into a control is tedious operation, fraught with error.

    You appear to have a card slot there to the left of the screen.

    Get yourself a CF card, a PCMCIA adapter...

    So I got around to this finally, and the lathe has been running without problems for the last week or so.

    Following Vanc's and Hu's advice I fitted the new angular contact pair to the spindle and...

    In the 90's and early 2000's (maybe still idk) Autodesk had a policy of using token copy protection methods only, leaving their software trivial to pirate.

    The rationale being that making it easy...

    That's a lot more severe than what I envisioned from your original comments.

    That's how Ti turns when you use an unsuitable geometry insert, like one with a micro-radiused edge for steel, and/or...

    As you mentioned it, Linux CNC is what I used on mine. The specific reason being that I needed the ability to write custom motion control / axis synchronisation routines for a custom process...

    Could well be from an M series machine, but those are servo amps, which were specified by the MTB, not Anilam. TBH Seymour I didn't know Anilam even made their own servo amps until you spoke about...

    These things are tightly regulated over here unfortunately. Industrial wood burners need a license I'm pretty sure. Waste oil for sure, and massive amounts of red tape to wade through.

    I have nothing to offer about your machine, but I'm curious what your gripe is with Lathes UK?

    I have bought from him a couple of times and always got what I paid for, thought he was quite well...

    We heat our machineshop, but I will say that it costs us dearly to do so. If it were purely for the comfort of the guys on floor I doubt I'd be able to make a case for it.

    Our shop is about 60m x...

    This has been my experience too. When you encounter a piece of Gr5 that does this, you also cannot polish it out. That's the way it looks and that's that.

    It is running in polar, G12.1 is there, a little bit after the tool call.

    Doing some small moves very close to the centreline, I imagine the error is from the C axis failing to keep up - i.e. very...

    If you have ball retention and your drawbar has any real pull, then your pullstuds will get dimpled. It's normal.

    Like Frank said near the start of the thread, those pullstuds are simply past...

    Mount an indicator on the spindle housing, with the stylus on the side of the spindle nose.

    If you can measure movement between the spindle nose and the spindle housing, then see my post #8.

    Had a quick scan over the Centroid offerings, it sure looks like the Oak should do everything you need it to do.

    Unless your CII was significantly different to mine you need analogue voltage...

    I retroed a CII lathe years ago for a special purpose. Won't tell you what I used as it probably falls into your don't want to hear it category.

    Anyhow, CII takes bog standard TTL quadrature input...

    I'm pointing out the obvious here, but nobody else mentioned it - if the movement is always in line with the Y axis, then unless you're testing with the spindle oriented every time, it's not the...

    My comment above about "only ever run aluminium" meaning worn out was more of a passing comment on peoples perceptions, rather than actual fact.

    Collet is twisting for sure, it happens when you are working in the collapse range and overtighten. The closer to the bottom of the collapse range to more they tend to twist. I have a rule in the...
