    Default A new 6230A and a question

    I am very happy camper having managed to pickup, move and install my new lathe. A brand new unused, 2 year old Toolex CQ6230A. Even the runin had not been done.

    Anyway the lathe was installed, leveled and the run in procedure performed while I figured out the gear changes, controls and preferred change gears.

    I have to say, I really, really like it. As it had never cut steel before, I had to start facing the turning down a test bar to commence the measurement etc. learning speeds and feeds etc and using an Eccentric tool holder. Very nice, just cuts turn the post a little and it faces. i can see some people use nothing else.

    I have a question though. I have a quick change AXA on the way with many holders, but as the new lathe also came with a set of index carbide cutters, i though I check the fit. My question relates to adjusting the tool height. I have searched the forums and could not find how to raise the heigh of the tool holders about 3 mm in the tool post. Do I have to make up a shim plate?

    I used the facing method to set the tool height on the Eccentric, but can't see how to set the carbides other than a shim.

    I have to say, I did tests at very slow, facing and finishing, and every thing work the it should. Thought nearly broke my back carrying the four jaw chuck.

    Cheers, Guys..

    PS how do you get grease marks off your keyboard? damn, just too excited with the new toy.

    Hi,
    On the standard tool post you will have to shim it up, with the axa you just adjust it by screwing the knurled height adjustment nut.
    Just remember to keep safe around it as they are unforgiving if you get something caught up. Also remember to not leave the chuck key in at anytime at all.

    Hey Dave, I hope you are well. Yes there is a lot of power in this unit, and acknowledge that the AXA removes the problem.

    I have been watching some of the chuck key threads and youtube examples. Right know I tread very carefully around it, but i can see how one could get complacent and then accidents happen. Just like with firearms and reloading, some habits need to be burned in.

    I don't think I will worry about the shims as i was only curious about the cut of the carbides, as the tangental tool is really very nice to use and cuts very nicely. It doesn't have a chip breaker in stand grind, so when i used a too slow feed cut, I think I had a continuos swarf about a meter long. I just have to play with the the feed speed as they were a little blue. But it was O1 tool steel in the chuck, annealed but still hard.

    Cheers, time to sign off. It been a big day with new toys.

    Default eccentric

    I am a new return to lathe work and have a similar sized machine.

    I also find that the tangential tool is fantastic. It is easy to set up and not so critical for speeds. I much prefer it to carbide for my use.

    Shame that there isnt a right-hand tool 'tho

    I have recently fitted my AXA and am reasonably happy - especially with the HSS parting tool and holder

    Shims are simple. Just use a cheap set of feeler gauges from supacheap or equivalent.

    Hi Roulston,

    I have the CQ6230, and it does everything I want. The QCTP solves the problem of getting different height tools on center. I went for the QA150 from Hare&Forbes, and now I'm stuck with paying $75 per tool holder. (Until I get around to making my own at least) I think you will be happy with the AXA.

    The other upgrade, I can recommend is to fit a DRO, I got a Meister from ebay and now wouldn't be without it.

    The main problems I have had with mine are.. The el-cheapo bearings in the chinese motor had to be replaced at one stage. The cast gear selector lever broke and jammed up the gear train, stripped the nylon idler gear Had to make a new idler gear and a new gear selector lever.

    I have a Danfoss VFD and new WEG 1.5kw motor to put in in the next few days. Although I will still mostly use the gear box as normal.

    Congratulation on your new lathe, I think you will be happy with it.

    Regards
    Ray

    +1 on the DRO, transforms the use of a lathe.

    In fact I am so impressed with mine that it will probably be the first mod for my new DM45 mill.

    Default Thanks all.

    Mine doesn't have cast gear selectors. I think I have seen five gear box options on these CQ6230A ranging from the Norton gearbox version upwards.

    Even the attached photo of the Crusader is not quite right. The four drums on the crusader are served by two drums on mine that have a dial (knob) and lever. to make the lateral or cross speed selection and lead screw speed.

    The only other difference is that mine does not have the lead screw covers should on the crusade.
    But I take your point. If i work it hard enough to need spindle bearing change, i would be surprised.

    On the other comment about the left and right version of the Eccentric i was not sure if this was a joke or not, but the one works at most any angle to the piece.

    cheers, Tony

    Hi Tony,

    On mine it was the bearings in the electric motor itself that failed, not the spindle.

    There are lots of different models of this particular machine, and badged with different dealers names.

    Mine was probably made by Shaoxing in 1993, I see that they list the CQ6230A on their web site.. but it wouldn't surprise me if there are others making the same model.

    Hi Tony,
    I thought I read somewhere that yours had the 4 dials, might be old age setting in,lol
    Is yours set up the same as mine like in the picture below?

    I wouldn't worry about the lead screw covers, their is a bloke in the UK that bought one of those lathes and then complained to the company because they advertised the lathe as having a certain travel, but because the lead screw covers where on it, it limited the standard advertised travel.
    I would prefer to not have them as I can see the lead screw and if there is anything on it, it's also easier to keep lubed. As can be seen in the picture, I have made a small cover for it at the headstock end to stop chips falling on it, which helps a lot and doesn't restrict travel.
    As Ray said it was his motor bearings that went after years of service. I have not heard of anybody needing to put new bearings in these type of lathes from new or old for that matter.
    Mine is a 2004 model and gets used a lot with some really deep cuts on some jobs, and is still running fine with no issues at all with the bearings.

    This thread from Will should give you some good information about setting up a new lathe, oil changing, bearing pre load and stacks of other info.

    Cheers, Dave, mine is the exact same one. Which is also the same model still on show in the Gasweld shop.
