    Default My new lathe - Need some advise please?

    Hi,

    So after searching for a decent second hand lathe the past couple of months, I decided to buy a new Chinese lathe...

    I just could not get my hands on a decent Colcester or Emco lathe... Good ones are just not for sale that often...

    Anyway... Yes, Chinese... So I did a lot of research, and my take off was the following:

    If you want to buy Chinese, then buy new. That way you can upgrade the problem areas, and also take good care of it. Most Chinese lathes will be sufficient for light duty use as a DIY machine, thus a new one could possibly outlast you. Most of the 2nd hand Chinese machines was mostly used in a commercial environment, and they are thus in very poor condition. ALSO, the bigger Chinese machines (in other words, NOT bench top) are usually of better build quality as well...

    So, I bought an OLD NEW machine... The machine is new, never been used, but was a display model in a shop since 2013.

    I now have to clean it, drain oils and make sure everything is good before I can start using it...

    It is a Micro-Tech branded machine... 320mm swing x 880mm BC. It is a gap bed lathe (I was actually looking for a non-gap bed). The Chinese number: CQ3236E

    It came with the 3-jaw, 4-jaw, faceplate, 4 additional change gears (only needed for some imperial threads, as most threads are taken care off with the gearbox), MT5 to MT3 bush for spindle, 2 x dead centers, 3 x reverse chuck jaws, follow rest, steady rest and tools... So very complete, as a new machine should be.

    Optional extras also on this machine (I think this is to make it CE approved): Emergency foot brake, Spindle guard, lead-screw cover. It also has the suds tank/pump and a work light.

    First question... How to clean the protective/shipping oil from bed/chucks/tools etc. ?? I've done some research, and most seem to agree that WD40 is the way to go.

    Then, I need some help with oils. I have 2 x manuals, and the one manual suggests:

    Headstock: Shell Turbo T-68
    Feed gearbox: Shell Turbo T-68
    Apron gearbox: Shell Turbo T-68
    Bed ways and oiler balls: 20W machine oil


    The second manual states the following:

    Headstock: ISO 32
    Feed gearbox: ISO 68
    Apron gearbox: ISO 68
    Bed ways: ISO 68
    Oiler balls: ISO 32
    Leadscrews: ISO 68


    Then I have read somewhere on the net that you get "special" way-oil for the bed ways...


    So what is available in South Africa, and what should I use for what?

    I obviously want to drain all oils as the machine has been standing for 7 years...

    Please advise...

    Thanks

    Welcome to the world of lathing! Looks like a good machine.

    Many chips I bestow on you ...

    Oil for my Colchester is as follows:

    Currently available:
    Headstock (ISO classification) - Shell Tellus S2 MX32 - 9 pints / 5 litre
    Gearbox (ISO classification) - Shell Tellus S2 M 68 - 2 pints / 1 litre

    Way oil - Mobil Vactra™ Oil


    To remove the protective oil, simply wash with paraffin. WD40 is way too expensive.

    Any industrial lubricant place will supply in 5l containers. This is the way I always buy mine.

    Speak to Rocol Lubricants just round the corner from you.

    Thanks!! This is a very generous offer!! Especially the fact that you are so close to me!

    I do have other help (the likes of mygoggie and Plunger), but their location is not ideal when it comes to physical interaction.

    I will most definitely contact you if I need assistance... I'm very excited to start working on the lathe, but first things first... need to sort out the cleaning and servicing...

    The first lesson you will teach yourself when using a lathe is to remove the chuck key from the chuck before starting the lathe.

    Actually, never leave the key in the chuck.

    Congrats . There is a big step up from the small bench lathes to the one you got now. I wouldnt do much in terms of lubricant for the chucks. If its got lube it just turns the oil into lapping paste when it mixes with swarf .

    I dont think its critical what oils you use as long as you are close to what is recommended. I would buy a one oil does it all. There is a company called Germ lubricants where I buy my oil. I use an oil called dynobear 68 . I cant remember if this was for just the ways or if I used it in my headstock as well
    i think I once put in a oil that was for hydraulics that they use for vacuum pumps in the milking industry but Germ are helpful.

    I think for the ways I also used dynobear 68 but they simply added an stiction additive into the oil so it stays on the ways.

    Some oils eat bronze and brass so you need to stay away from that as there are shoes if you can call it that made of phospher bronze that are used for moving the gears back and forth to mesh.

    Germ will also sell you 5 l of oil.
    Its a splash system so the oil needs to be able to get splashed to the top and into the oil reservoirs so that it can lubricate the spindle bearings.
    At least that is how most of these size lathes work. The more expensive lathes like that Monarch are very different .

    Does it have a camlock chuck. ?

    I spoke to my mentor and guru and he suggests sae 10 or iso 32 viscosity for the headstock but not motor oil as it has detergents for internal combustion engines which will etch your ways. I think dynobear68 is a way oil suitable for the carriage and gearbox and ways

    I found the container of the first time I did an oil change and I used caltex rando HD 68 a five liter container.It says antiwear hydraulic fluid and milking machine vacuum pump oil.

    Thanks
    congrats on your purchase SinWolf, that is a very nice lathe.

    Never use grease in the chuck, ever.. Strip it if you want to, they are not complex affairs, give it a good cleaning and then a light oil on the moving parts, not too much as as with Plunger’s statement, too much stuff eventually builds into a grinding paste.

    I am rather anal about cleaning my machines, probably to my detriment, but I work better that way, so the chucks I have often get stripped for a deep cleaning, in fact my 3 jaw is starting to bind a little, so here we go again...

    If I may suggest next on your list is a quick change toolpost which you can purchase from Adendorff which includes 4 lathe cutting tool holders, and if you need more, which you eventually will, you can purchase the individual holders from banggood.com..
