These Add-ons include the electronic system that will control the machine, cable management, and the tool that will be mounted to the machine.


About the OutBack CNC

The OutBack CNC Machine is our strongest, most rigid CNC Router model. The OutBack has upgraded the motion system on all Axis from our tried and tested wheel system to heavy-duty HGR and MGN linear rails with recirculating ball bearing sliders. The HGH15CA Bearing is commonly seen on larger automation systems and CNC Machines with heavy duty linear actuators. By securing steel linear rails to the aluminium extrusion, as well as replacing roller wheels with recirculating captive bearings, the rigidity and overall dynamic strength of the OutBack CNC model have been immensely increased.

The OutBack CNC has also an upgrade to the X-Axis and Y-Axis C-Beam Extrusions to our famous C-Beam HEAVY which has a 72% improvement when compared to a standard C-Beam under the same conditions.

The OutBack CNC is designed to be capable of machining wood and soft metals with a heavier more powerful spindle. Deformation and chatter are minimised with the improvement of the C-Beam HEAVY extrusion paired with the installation of steel linear rails.

About the Tool Mounted to the Machine

The Spindle weight and size were a key scope that was addressed when designing the OutBack CNC. The OutBack Z-Axis is designed to easily carry up to 9kg. This is perfectly suited for a range of Spindles as well as Lasers, Plasma Torches and most Routers and Trimmers (Makita, Dewalt, Bosch etc…). When using a Router/Trimmer we generally recommend the worktime to be up to 1.5 hours continuously running.

Approximate Cutting Area (mm)

X-Axis: 1275mm
Y-Axis: 815mm

Z-Axis: 135mm (with 12mm spoiler board)

On the X and Y-Axis, you can also subtract the diameter of your Tool for the Travel Area with a specific tool.


Key New Features

Below are some of the Key Features of the OutBack CNC.


HGR Linear Rail on Y-Axis and X-Axis

Both the X-Axis and the Y-Axis use HGR Linear Rail for their motion system.

The HGR Rail is made from strong steel and is secured along the length of the aluminium extrusion which creates a very rigid actuator.

Chatter when working on composites and metals is reduced with the installation of the steel rails.

Another feature of the HGHCA Bearing Blocks is the high deflection tolerance. This allows for heavier weight and larger force to be applied to the moving gantry on the machine which in turn allows the machine to use a heavier tool such as a 2.2kW Water Cooled Spindle.


Increased Working Height

The working height on the OutBack CNC has a working height of 150mm or approximately 135mm if a 12mm base-board is installed. The taller height is achieved without accuracy loss due to the strong X to Z mating and linear rail being used on both the X-Axis and Z-Axis.


Stepper Motor Mounting Brackets

New Stepper Motor Mounting Brackets are used on the OutBack CNC to create a stronger, more secure fixing for the Stepper Motors.

C-Beam HEAVY

Our famous C-Beam HEAVY is installed on the X-Axis and Y-Axis. This upgraded extrusion makes the entire machine significantly stronger, especially in the X-Axis.

X-Axis ‘twist’ that is experienced on 1500mm X-Axis that has a heavy 2.2kW Water Cooled Spindle is reduced with the installation of the thicker C-Beam HEAVY with a 72% improvement when compared to a standard C-Beam when inputted into a computer simulation to determining machine deformation under different forces and loads.


Spoiler Board Design

 

The OutBack CNC uses a new Spoiler Board design that secures the two Y-Axis actuators together in 5 places on a 1000mm length and 7 places on a 1500mm length. This makes the Y-Axis incredibly rigid under heavier loads.

Another great feature of the Spoiler Board design is it secures the baseboard along the entire length and makes it easier to hold down the baseboard which is particularly helpful if working with composites or metals.


Slimline Z-Axis with MGN 15 Rails and Bearings

MGN Rails are a low profile version of the well known HGR rails. The New Z-Axis uses High-Quality MGN Series Linear Rails and MGN15C Bearings. This combination of rail and bearings offers high rigidity and precision accuracy in linear motion.

The OutBack CNC takes advantage of the low profile MGN rails that are responsible for keeping the centre of gravity as close as possible to the X-Axis gantry. This simple “trick” mitigates the X-Axis from twisting and causes less stress on the Y-Axis wheels.


Cap Head Screws – Also known as Socket Head Screws

The OutBack CNC has upgraded any screw that does not need to have the Low Profile Head to the Stronger Cap Head Screw.

This simple upgrade makes the assembly of the machine much easier as it minimises the risk of stripping the head of the screw.


Jaw Couplings

Jaw Couplings have been used to connect all Stepper Motors to Lead Screws.

Jaw Couplings are stronger and longer-lasting by design when compared to their Flexible Coupling cousins.

Jaw Couplings are more precise in acceleration and deceleration.

Jaw Couplings have less backlash than Flexible Couplings.


Lead Screw Tensioning Nut

The OutBack CNC has upgraded the outer locking collars that hold tension on the lead screw to the new Lead Screw Tensioning Nuts.

This specially designed nut when installing a Lead Screw in tension helps reduce Lead Screw ‘whip’ which occurs in Lead Screws with lengths greater than 1000mm. Installing the nut onto a Lead Screw helps ensure your machine runs smoothly at higher feed rates.

Lead Screw Transmission System

Lead Screw machines are designed to achieve high-resolution levels and great repeatability. It also requires little ongoing maintenance, with nut-blocks often having a functional life of longer than 3 years if the machine is taken care of.  Lead Screw transmission combined with a bipolar stepper motor has a resolution of 0.04mm without any microstepping settings. Considering 1/4 set in your microstepping settings, the same Lead Screw can provide 0.01mm resolution.

All of our Lead Screws are specialised ACME thread TR8x8(P2), in basic terms, this means one revolution of the Lead Screw will make nut-block travel four times further than a standard threaded rod which is only a single start. Furthermore, this precision trapezoidal (metric) lead screws’ pitch and diameter are a perfect combination of high torque and speed.
