Perfect for standard 4'x8' sheets, the greenBull 4X Heavy Duty CNC machine is great for all you machining needs. Don't let the wooden structure fool you. The greenBull can tackle almost every job you throw at it with precision and accuracy. Great for wood, acrylic and even light aluminum. We also offer a Long Z option that has the capabilities to machine thick foam.
Table or Torsion Box Not Included
Big Business Production. Small Business Cost.
The greenBull Heavy Duty CNC is a fully equipped CNC machine kit that will allow you to mill full length 4' x 8' sheets. We stand by our conviction that this machine is the most affordably priced, heavy duty CNC kit on the market today.
How do we know for sure? Because we use it every day in our shop. That's right. Our greenBull 4X self-replicates daily, building a clone army to equip the masses with the tools to achieve industrial dominance across the globe.
The greenBull series, like all our machines, is American-made in the great state of Texas. Whether you're looking to automate the process for general woodworking applications, cabinetry, sign-making, construction, or milling other material like acrylic or light aluminum, the greenBull has the power to significantly reduce your production time.
Did we mention we can also throw a laser on it? You bet. All machines in the greenBull series come with the option to equip a 40W CO2 laser tube on the gantry so you can cut and burn on the same machine.
Basic Kit – with 2.2kW Spindle - Includes everything in the basic kit and a 2.2kW Spindle with 220V Inverter. Does not include: Table, Computer, Software, Bits (end mills) Spindle is water-cooled and requires some additional wires and plumbing equipment. We recommend you seek a licensed electrician for installation. Note: If you don’t have access to 220V power, we can provide you with a 110V inverter. Contact us for a custom quote.
Assembled Version – with 2.2kW Spindle - Includes everything in the basic kit – with 2.2kW 110v/220v Spindle. We assemble the gantry for you and ship it to you in a crate via freight carrier (you choose during checkout). You will still need to construct your own table for the gantry and install the aluminum rail on it.
Computer and Control Box Options -
Basic Assembled Control Box redFly – with this option we install and wire the electronics in a custom-made control box. This is a great option if you want to save the time of wiring and mounting the electronics yourself.
Assembled Control Box with Deluxe Computer – Includes the control box option plus an integrated computer built into the control box. The computer features an Intel Pentium 3.0 GHz processor with 2GB of RAM and a Seagate 1TB Internal Hard Drive. This package includes Mach3 CNC software and a Windows 7 Professional license, which we will register in your name and pre-install on the computer for you.
- Actual table dimension for the 4'x8' are 55.25"x123" (this will create a 1 inch overhang on both sides).
- The overall design has increased rigidity for the new routing/milling area but still maintains the aesthetics that are common across all of the machines on this site.
- To guarantee that the gantry doesn't flex at all, a series of ribs were added within the gantry box making the entire gantry very similar to a torsion box.
- The motors selected for all of the axes are NEMA 34 with 1/2" shafts (driven by 6.0 amp drivers).
- The dust shoe is redesigned to provide better dust extraction capability.
Important Things to Know:
- The entire machine kit will take about 10-14 business days to produce and send out under normal circumstances. During busy periods this could increase to 15-21 business days. You can always contact us for an accurate estimate before purchasing. Assembled Machines will take longer as they have to be produced to order. Expect a lead time of 3-4 weeks for assembled machines.
- We include a standard amount of 50 feet of motor cable for the greenBull 4X. The recommended length is for systems in which the computer will be placed right next to the machine. If you plan on having the computer further away from the machine you will need to purchase longer cable lengths. If you are unsure about how many feet of cable you need, please call or email us and we will assist you.
- The Spindle will require 12/3, 14/3, or 16/3 gauge cable for wiring from the inverter to the wall. You will also need 4 conductor wire for wiring the Spindle to the inverter as a 4th wire for ground is needed. It is important to understand the electrical requirements for wiring the Spindle, so for this reason we strongly recommend you check with a licensed electrician before attempting to wire it.
