    Industrial Grade CNC For Pergolas

    Hello all, I'm new here and this is my first post. I joined this site primarily because I'm seeking the opinions of some experienced CNC woodworkers. I recently started a small business out of Denver, CO after four years in the Marine Corps. Right now, we are operating on a 4x8 EZ Router with a 3HP Porter Cable Router. I'm meeting with a potential investor soon who wants to fund my company to start our own shop and purchase our own machine. Right now, the front runner is a Legacy CNC 4x12 or 5x12 with 7HP water cooled, auto-tool change spindle and at least 9 in of plunge on the Z axis. The auto tool change capability will save plenty of time as we machine many different components for a single Pergola, and some components need two different cuts with different tools before they're finished.

    I'm curious to see what else is out there though. We will be looking at about $40,000 for the aforementioned machine. Are there any more affordable options to procure a similar CNC router which is built to run industrially? (linear bearings are a must)

    Any suggestions or comments are greatly appreciated.

    Hi there and welcome to the forum.

    There are a lot of manufacturers out there in the industrial world.

    CR Onsrud, Techno, CamMaster and MultiCAM are just a few.

    There are many more.

    I would suggest doing an internet search of CNC routers and do a pile of due diligence.

    pending on what thickness you plan to cut from one side..
    generally 1:6 what said rigid solution yet..


    means with 1 in diameter you can cut safely 6 in depth..


    for a 1 in diameter tool you might need 5-7 kW ..
    actually what you see spindle power means for single phase most time..
    means counting on 1 phase it comes 7kw, but its actually 3x 2.5 kw..


    make a quote on onsrud, and thermwood


    they make you a router with moving table and a decent gantry..


    there are one more manufacturer, Haas ... they also make router and that's so heavy that almost like a gantry mill..


    I saw youtube video dealing with beams.. using circlesaws and long bits..

    Re: Industrial Grade CNC For Pergolas

    thank you Jason


    I knew im still nubie for computer :-)


    I typed into wordpad, and now just simply copy...


    =============================================


    thinking over this..


    in the past i worked as ""installer"" at a building supply


    means window, door and practically everything..


    we built pergolas of 2x8, 2x10.. and used 4x4..


    on my own i made of cypress a ""tent"" a freestanding roof front of a house using 10x10 8x8 and 3x6 material..


    i built it with chainsaw, chiseld out the mortising, and cut tenons with skilsaw and sawzall where hard to reach..


     


    so for 2x10 and 4x4 i think any router will work with a decent spindle.. not 5 hp spindle.. that just cant hold the required tool..


    to cutting affordable trough a 2x material, youll ending up a 1 in dia tool.. to cut the curve out on the board end..


    on the other end, the industry pretty much prepared for working with lumbers, working with beams..

    and an italian, and i think taiwanese too...




    https://www.youtube.com/watch?v=rZGOJYUtTbU


    http://www.uniteamcnc.it/all-product...roducts/artek/






    but these above i think way more than planned 40K


    if i were you, i would check first what chinese offer..




    http://www.alibaba.com/product-detai...053986769.html






    this is the first i found.. there are hundresds of offers..


    about 24K you get a machine.. but you have a lot more cost coming for this.. power in your shop, possible forklift and other things you might dont thinking right now


    any american manufacturer you go.. for 40K not looking possible a 12 in Z and 9 or more kw spindle to work..


    just an example, multicam 3000 router with a 4kw spindle, atc about 55K at the texas plant, but you have to buy trough on reseller and you might ending up at 100-120..


    if you go to lowes, a stringer cost about 9 dollar..


    you cant cut with 3-4 kw spindle a stringer affordable


    also if you plan deep cuts.. the atc might dont work for you, because the tooling held in a din or iso chuck, and you might cant put into a 10 in long 1.5 in dia tool


    so just think twice... before you go out for anything..


    it can spiraling in very high expenses..


    just my two cent on this..

    Re: Industrial Grade CNC For Pergolas

    Thanks a bunch gents! Currently, the two front runners are Lone Star Cutting Solutions' EZ Router Scorpion with a HSD 4kw, 5.5 HP auto tool change spindle and plenty of Z clearance. Quoted at about 41k for the full setup.

    Also, I'm still waiting on a quote from Legacy CNC for their Criterion machine with a similar spindle and auto tool change capability. I expect it may come out to around the same price.

    Cutting crossbeams and rafters is fairly simple as they are 2x8 material which is only 1.8 in thick. The posts are 6 in thick and we need to machine 1.25 in notches out of each side and drill 3 in deep for the bolt holes. This requires that extra Z height. By far, the most difficult cut (in terms of potential for mistakes) is cutting arched braces out of 3x12 material. The bit tends to bog down a bit with our current 3.5 HP Porter Cable Router, so we've had to make an extra toolpath about .3 in around the original cutout to allow the bit some breathing room, and so the chips have more area to exit the material. I think this problem would be mitigated with the right bit, a 5HP spindle, and having the dust skirt on.

    Thanks again for the advice! Cheers
