    Default About to buy a cnc router. Has anyone herd of this one?

    I am looking for a 4x8 cnc router and came across this one. The price is great, but does anyone with experience think this is worth buying? I am new to cnc, but I am dead set on purchasing a 4x8 machine. I have been looking at industrial pro series, and laguna swift series, but this is half the price. I am also speaking to someone about building me one but he said it would weight 500 lbs. So that concerns me. Since all the other machines I have looked at weigh closer to 2,000 lbs. Should I be concerned with that?
    The guy who said he would build me one told me he uses nema 34, y axis is rack and pinion, x and z ball screw. 6" gantry, welded steel tube and aluminum gantry, a 3kw water cooled spindle.all for about 8 grand. Does this sound good?

    What about the DIHORSE? this one weights a lot more so I am thinking it is much more sturdy but appears to be Taiwan parts, not sure if that matters. here are some specifics.
    Traveling speed: 25m/min( 984.3in/min )
    Cutting speed: 15m/min( 590.6in/min )


    Control system: DSP A11 hand controller
    Drive system: CW stepper motor and JMC driver
    Guide rail: Taiwan 20mm rail guide
    Spindle: 3.0KW water cooling spindle
    Machine frame: Heavy duty frame
    Table: Aluminum T-slots table
    Dust collecting system: Double bag 3kg dust collector
    Software: Type3 and Artcam
    Carving Instructions: G code
    Working voltage: AC220V/50-60HZ

    I am looking for a heavy duty cnc machine but I would love to keep it under 10,000. Is this realistic? Any advice would be appreciated. Thanks

    The first thing to keep in mind is that in best case you will get what you pay for.
    I would ask the manufacturer to send some closeup pictures of the machine construction. expecially about the surface finish at the rails.
    I don't think any chinese companies build Taiwanese rails and screws etc into their machines unless they are asked to do that, then they may do it for extra cost,
    but they often telling that even when they using Chinese parts. Nowadays you can't really distinguish between chinese and tiawaniese rails and screws, the only difference is often only the quality.
    Chinese often even place hiwin marks on the rails, because they have the equipment to do the marking, they just don't have authorization from Hiwin and quality control by Hiwin.

    It's hard to give you an answer if it will worth to buy a machine or not. The heavy weight is a good sign, but it is not the only thing, because weight put in the wrong places make a machine even worse then if it was light weight. high weight is usually good, but only if the design is good.

    "Heavy Duty" means different things to different people. I would say no, it's not realistic.

    Can you post some links to what you are looking at?

    You have to be careful with chinese machines, as you don't really know what you are getting. If the machine is really cheap, I'd expect the quality to be fair to poor.
    And if you are buying direct, you can expect customs fees in the $1000-$2000 range. There are several posts from users hot with these unexpected fees.

    And keep in mind the included software is likely to be illegal pirated copies.

    A list of a few components tells you nothing about what you'll end up with. Someone can build a really bad machine with good components, or a decent machine with average components. It all comes down to the skill of thebuilder, and whether he knows what he's doing.

    One option that would be close to your budget is a CNC Router Parts Pro series kit.I wouldn't call it "heavy duty", but it's a quality machine with excellent support, for the price.

    http://www.dihorse.com/dh-1325-cnc-router This is the router I was talking about. It says it ships free in the USA.
    This is the website of the person Ive been talking to about building one. https://www.dbcncrouters.com/
    The DB routers builder seems very helpful and will not only deliver the machine but provide training upon arrival.

    The chinese machines can get you a lot for the money, but again, at that price, I wouldn't expect a high level of quality. I've helped several people in the last year that purchased large chinese machines that didn't work well at all, and needed a lot of work to get them up and running. Poor fit and finish is common, as are sub par electronics. You're paying 1/3 what an american company would charge, and in a lot of ways, you get what you pay for.

    As for the DB machine. I wouldn't recommend any machine that uses round linear rails. And I'd want to see the machine running in person. You just don't know what you're getting.

    If your set on buying a big machine for the lowest price, it's almost guaranteed that you are going to run into issues of some sort.

    Ships free means for Chinese that they put the machine for free on the board of a vessel and then when the machine arrives you pay for the vessel shipping anyways. You also pay customs and you pay the port fee when they move your machine from the vessel and you also pay for the rest of the transport, crane fees and other things. I would separate 2000-2500 dollars to pay these if you select the "free shipping option".
    I'm in Europe so I can't tell you what are the exact fees in the USA, but when we import heavy and large stuff from China shipped on vessel then it is still cheaper if we ask a local company who do international shipping and make a contract with them for the whole shipping, that is still much cheaper than if Chinese "ship it for free".

    Round rails are great for woodwork, because they wear out from dust slower than rectangle rails and usually high precision is not required to cut wooden boards and to do works like that. But for applications where you need precision rectangle rails are much better, because they hold the geometry better, but for them to be better you need a precisely manufactured machine frame geometry, otherwise they will strain and will wear out fast.

    Sorry, but I disagree completely. Round rails are not nearly as rigid as profile rails, and often result in a "loose" machine.
    And profile rails should last a lifetime for a hobby user. They don't wear out from wood dust.

    Thank you all for your reply. Could you elaborate on the round rails verses rectangular rails. For instance why would round rails be less precise? With all this being said, What do you guys recommend? industrial sells their pro series last year model for 14,999$. thats about the highest I could go. Any recommendations?

    The DB CNC said he could use rectangular rail on mine if Id prefer for added cost. He uses the circular to keep cost down I guess. Is this something worth investigating? He also said I could come buy and take a look at his.

    What about the industrial pro series?

    I have to partly disagree.
    Round rails are not as rigid as rectangular rails, this is the same what I wrote, but for them to work properly the machine frame has to be squared properly, otherwise they will jam and lock and wear fast.
    Profile rails do wear out from dust easier, because the carridge is more tightly packed with balls and is better sealed, so if dust once gets in it will destroy the balls for sure.
    With round rails the balls are not that tightly packed and so dust can come out as it went in.
    I destroyed a few square rails on my plasma machine. the plasma dust ate the balls and the rails. finally I put on some SBR round rails which are still working fine.
    For the lower rigidity is why I adviced the round rails for wooden work only and I can add plasma work too.

    When you buying a complete machine I also advice to get it with rectangle rails possibly with way covers on them, so dust can't get in.
    Assuming that the manufacturer knows what they are doing and can make the frame perfectly square and straight then the rectangle rails will really last forever and will give you high rigidity.
