    wEDM noob - surface finish in practice

    If it was just about a few parts I would definitely not be looking into buying a machine for them 😅 I was hoping to prototype and maybe sell them too, but I have also more stuff that I thought would be a good fit for a wire EDM. At least until I learned operating them is much more expensive...

    wEDM noob - surface finish in practice

    Sounds interesting. Not saying it's definitely EDM cut, but that's what I found in their brochure at PWT: https://pewetools.de/wp-content/uploads/Special-features_pewetools.pdf.pdf. Might be the information is old? Maybe they started with EDM and moved to sth else.

    wEDM noob - surface finish in practice

    I think you can totally change my mind - that's why I was asking! It was one of the ideas, definitely not the main one and definitely not something I envisioned as a main source of income - I just had an idea for some specialized holders for some things that otherwise you would have to cut from...

    wEDM noob - surface finish in practice

    Thanks for a detailed answer. I've read about lack of support for Brother, but I wasn't fully aware of the differences between an EDM machine and a CNC mill or similar machines. It would definitely be a risk, but my hope would be to use it at least for some time and then hopefully if I'm able to...

    wEDM noob - surface finish in practice

    I have no experience with EDM, but I know that PWT from Germany cuts multifix tool holders on a wire EDM machine. I think it's because of the teeth profile on the back. I don't have much production experience, but for me it would be quite a hassle to cut it on a CNC milling machine. I guess if...

    wEDM noob - surface finish in practice

    Hi, I am setting up a small prototyping shop on a budget and I was wondering about buying a wire EDM but my main problem right now is floor space. I heard a lot of good things about Brother HS-50A and it’s pretty much the only machine I found that is both cheap on the used market, well regarded...

    Internal cylindrical grinder spindle lubrication

    Thanks for all the answers, I'll try to get an oil like types mentioned here.

    Internal cylindrical grinder spindle lubrication

    A while ago I bought a spindle from a cylindrical grinder to use it on my lathe. I'm setting up a prototyping shop and I don't have space for a proper cylindrical grinder, so this is the next best thing. I have no idea, however, how to lubricate the spindle. It's KR40-250 model from a company...

    Jones and Shipman 1400 - spindle doesn't turn on

    Thanks for the replies! And also the problem is really embarrassing, I'm hoping you don't ban for being an idiot :D I wrote that post after leaving the workshop as I didn't have time to troubleshoot further, but for some reason I assumed it must be something in electrics. After I got back to...

    Jones and Shipman 1400 - spindle doesn't turn on

    I'm trying to turn on the Jones and Shipman 1400 I scored on an insolvency auction. It's visually in a good condition and so far most of the stuff worked, but suddenly spindle doesn't turn on anymore. After I connected the grinder I turned it on and I turned the spindle on for a few seconds (I...

    Moore G18 or Hauser 3SM jig grinders capabilities

    Sure, I know the reason - Wire EDM is taking over most of the uses of jig grinders and jig borers. That said, most of the wire EDM machines are too big for my workshop *and* I'm starting with a relatively low budget.

    Moore G18 or Hauser 3SM jig grinders capabilities

    Hi, I'm setting up a shop for prototyping, some restoration and fortunately some client work in the future too. Prototyping would be for my own products and some of them would require a good precision for some of the features. I think most of the time I could do just fine with a milling machine...

    Variable belt drive vs a gearbox

    I totally agree that a VFD is better than a mechanical system, but then a gearbox can break as well. And then repairing a gearbox is also expensive, especially if you can't order a replacement gear. But I guess what I'm asking is: what exactly makes variable drive systems more expensive, more...

    Variable belt drive vs a gearbox

    Sure, but my question only concerns manual machines with a mechanical transmission. I know that a VFD with a strong motor is much easier to maintain than a manual transmission, but I wanted to compare two types of manual transmission systems - a gearbox vs a variable pulley system. To make it...

    Variable belt drive vs a gearbox

    That's the part I don't fully understand. I mean, yes, if the variable drive is controlled by a DC motor or hydraulically then I undersand it(now I realized one more company doing this kind of thing was Cazeneuve - the Cazeneuve 360 toolroom lathe had a hydraulic control for the variable drive...

    Variable belt drive vs a gearbox

    That's a weird comparison, what does a car have to do with a machine? In my post I listed 5 companies that produced lathes and milling machines with variable speed drives. All of them more than one model, with some companies definitely having more than a few - like even Schaublin - Schaublin 13...

    Variable belt drive vs a gearbox

    Hi, I've been thinking about a design consideration for milling machines and lathes, specifically ways to change speeds. In CNC machines these days there is often only an electrical control of the spindle speed, but in many manual machines a gearbox or another mechanical transmission is used. I...

    Forklift battery cleaning - rust-like residue?

    Hi, A while ago I bought an old electric forklift with a working battery, just enough for my needs as I could easily rearrange and move machines in the shop for a few hours without any problems. The problem is that the battery had quite a lot of oxidation on some of the contacts, so I wanted to...

    Aral Sumurol CM 46 equivalent - hydraulics for a CNC milling machine

    Hi, I bought a CNC milling (Stanko SMO 32) and the manual calls for Aral Sumurol CM 46 for the hydraulics (I think only tool clamping, but I haven't gone through the entire manual yet). I can't find it anywhere online and I can't find equivalents. Is anyone aware of equivalents for this type of...

    TOS SV18RA lathe

    Thanks for all the help! And as zephyrous mentioned there are indeed holes for a lifting bar that are accessible after removing the panels on the front and the back under the headstock. When lifting it we also used the ribbing of the bed and it worked good. I already sold the lathe, but if...
