    Very impressive to get that much depth of cut out from a mini lathe. I started using the aluminium inserts on my ancient 1930s benchtop lathe and they are so much better then the regular steel cutting inserts. The best thing about them IMO is not how deep you can go, but how shallow a cut you can take; the regular steel cutting inserts just rub the surface if you try a really fine cut.

      @@taxicamel _"If you have failed to machine the correct dimension, "_
      Has nothing to do with this. As an "expert" you should be aware that small lathes simply don't have sufficient power (or rigidity) to take deep cuts. That's fine with HSS, but not so much with conventional inserts which is why they aren't well suited to small lathes. The aluminium inserts do work on small lathes however.

    This is a very interesting video, because most people say you can't do much machining on steel with these mini lathes. this method seems to work pretty good. it shows that mini lathes can machine steel providing a person is patient. which is really all a person can ask since these lathes are hobbyist grade and not professional grade lathes. something that I noticed, is the cuts seemed to get easier and cleaner. the smaller the diameter the stock got. which makes sense since the smaller the diameter. the easier it would be on the lathe and the cutting tool. for me I think they are very suitable for making bushings and other things like that. however I'm curious how they would do on stainless steel. I'm going to have to watch the other video to see what the outcome is.

      I've been using my mini lathe for about 4 years now, and have turned stainless, mild and cold rolled steels, bronze, brass, aluminum, plastic, lead, cast iron, and the only thing I failed on was a mystery metal that broke 3 inserts (turned out it was piece of a hydraulic shaft, that was case hardened). I've never done that depth of cut on mine though.

  • @machinist_matt
    @machinist_matt 2 роки тому +2

    I think people worry way too much about "chip breaking" does it even matter for the home machinist? Whenever I get that long curly swarf the cut "feels nice" so surely you're doing something right!? I suppose there is a safety factor to consider.
    Anyway that's a great DOC for a mini lathe! I did some experimenting with carbide a while ago and my findings match yours, although I didn't dare go all the way to 3mm. It seems carbide likes being pushed, but only if you have the power and rigidity.
    I was amazed recently at my Cowells lathe taking 1.5mm (total) off a relatively large diameter of steel! Albeit with a very sharp HSS cutter and very slow rate. But still impressive. If you're not familiar with the Cowells lathe it's a tiny micro lathe more suited to watchmaking! Sometimes I wonder if we are too timid with our machines?

    During my apprenticeship the machine in the shop we had mostly used was exactly the same model as the one in the job-school. The difference was that the switch for the direction on the shop machine was the opposite of the normal setup for that machine so if you turned the one in the job school on with the habit built up in the shop you'd run the machine in revers. Took one guy 2 broken inserts and serious confusion from the teacher before the mistake was found

    Outstanding stuff! I use the ground inserts more than half the time I am cutting on the lathe. When you are experimenting for best surface finish, take a look at different cutting oils. Every machinist has their own favorites, but I have been surprised by how much performance can change with different types. For steel, my current favorite is made by Rigid, but I would recommend you try several. You will find your own favorites quickly.

  • @smallcnclathes
    @smallcnclathes Рік тому

    I tend to use moulded inserts in the manual lathe too. Ground inserts are a bit fragile,. However never a problem in the cnc unless I do something quite daft. The inserts for aluminium certainly make a lathe think it has had a motor transplant. I think if you want the chip to have a chance of breaking, you may need to double the feed and halve the depth of cut. That works for me. Although that long spiral is at least able to be controlled, not like it is a long straight continuous knife edge waiting to bite you.

  • @robertburns2415
    @robertburns2415 2 роки тому +2

    That was a good assessment of what your tool is capable of doing although there are a couple of factors I think you didn't consider. number one volume of material removed in cubic centimeters per minute the larger the diameter the more material you remove per minute stated in cubic centimeters. Such as 1 mm deep cut on a 50 mm diameter removes more material than a 1mm deep cut removes on a 25mm diameter for the same length of cut.
    Number two the absence of coolant. Coolant can greatly increase the efficiency of a tool by putting a barrier between the tool in the material also the coolant causes the chip to take the heat of the cut and the chip reacts differently when it's hot rather than when it's cool try these and tell me what you think.
    my best wishes

  • @gabster118
    @gabster118 2 роки тому +1

    I mean yes it can be done, but there are a few things to consider here. 1214 is a free machining steel, which machines like butter compared to 4140. While the mini lathe is managing that depth of cut, the feed rate is really slow and you would be better off taking smaller depths of cut at a faster feedrate. I know my 650kg hobby lathe will happily do 3-4mm DOC at 0.2mm/rev in 1214. A “fullsize” lathe wont just do a 2mm depth of cut, it will go much more.
    The inserts you are using aren’t brittle per se, they are the same carbide just with super high positive rake and razor sharp edge for machining soft materials. They just don’t hold up because both of those things lead to highly reduced edge strength.

    High Speed Steel calls for lower cutting speeds and heavier depth of cuts. I prefer tangential HS tools on my lathe.
    Originally my lathe came with a 550 W single phase motor, but I bought a three phase 1.5 kW motor and a one - to three phase frequency converter after I discovered the motor to stall when turning with carbide inserts.
    Since then I've only had a few occasions with belt slipping instead and only turning with HS steel.

    There is a video somewhere on youtube where a guy takes a 25mm depth of cut with a mini lathe if I remember correctly. He’s done loads of modifications to the machine to stack everything in his favour and it did work.
    However when comparing cuts, depth of cut is far from the only metric. If you want to see how quickly you remove material you should calculate volume of material removed per unit of time. (Inch^3/minute or mm^3/second). Comparing depth of cut while slowing down the spindle and feed is usually not faster than regular roughing strategies because of the compromises involved.

    Is that 1214 or 12L14 ? The chipbreaker is designed for aluminium. I find they break steel chips if you reduce the DOC and increase either feedrate or rpm or both.

    Stupid question - what's the issue with one long chip? Is it just cumbersome to deal with?

    • @vinland5558
      @vinland5558 Рік тому

      A bit late, but one of the risks of a long chip like that is it wrapping around the part - marring the finish - or even getting wrapped around the chuck, spinning around and picking up more long chips like that. A long whip of very thin very sharp steel flying around at hundreds of rpm is dangerous for the operator.
      If it doesn't pick up like that and instead continuously feeds downward, you may find yourself grabbing sharp steel line when trying to stop your feed too.

    Anyone have an idea of the rigidity difference between this lathe and a 9x20 lathe? I have a 9x20, and I've always assumed it was just a bigger heavier 7x14 with similar rigidity, but now I'm thinking it may be quite a bit more rigid. Not that 3mm doc is bad for a mini lathe, it's incredible.

      I'm feeding it manually, and how much I push it really depends on how much the motor can take. You get a good idea with feeling when the motor is maxing out, so I can't really give you a quantified feed rate. Cheers

    well it's a lathe ua-cam.com/users/postUgkxN9zrzkkhnjUF5PQbuA_B1gYdsfCu9k6z but it wasn't what i would have anticipated. Headstock, tailstock, carriage apron are manufactured from aluminum now not cast iron. The spindle diameter for the bearings is too small allowing for a few play in the spindle so I am using some blue Loctite to take out the play.

    Correction.
    Depth of cut has nothing to do with the amount of material removed.
    You could be 2mm into the part while removing less material with an edge of the cutter.
    To make this test anywhere a curate, you have to compare results with a power feed.
