UCCNC CONTROLLER

The StoneyCNC spec i2rA CNC Router for the European market is fully PC based controlled by UCCNC industrial controller and software. This PC based control allows for real time feedback of machine position to minimise mistakes. There is unmatched graphical user feedback to the operator. It is compatibile with a range of common CAM packages. Most importantly it is very intuitive operation for fast learning. 

SUPPORTED LINEAR GUIDEWAYS

Our linear guideways utilise recirculating bearings between a prismatic rail and a bearing block. The coefficient of friction on our linear guides is only a small fraction of what is created by traditional round guides, and are able to take loads in all directions. With these features, our CNC machines achieve high precision and greatly enhanced moving accuracy.

CAST GANTRY SUPPORTS

Heavy components travelling at a high rate of speed generate high forces of inertia. The horizontal gantry support (located beneath the table), and the vertical gantry legs take the brunt of that force. Each gravity cast aluminium component is powder coated and engineered to be completely overqualified for their job.

STRUCTURAL STEEL FRAME

You wouldn’t build a home on a compromised foundation… Nor should you build a CNC router on one.  Our welded, structural steel frame is heavy, rigid, and accurate. It supports the weight of your i2rA machine with ease.  It also offers mounting flanges in each corner to secure your machine to an optional i2rA stand, or your work surface.

INTERLOCKING ALUMINIUM TABLE

This is a seriously strong table.  The massive 30mm thick extruded aluminium table provides a strong, flat surface to support your material.  Integrated T-slots allow placement of hold-down clamps in any location, and a sacrificial MDF spoil board ensures that your table will always remain flat and damage free.

HIGH PRECISION BALL-SCREWS

Motion on every axis of every i2rA machine is controlled by high-precision ball screws.  These ball screws utilise recirculating ball bearings to provide close tolerance and offer unmatched accuracy.  Their ability to create low internal friction, while withstanding high thrust loads at high rates of speed, is paramount to the accuracy of each i2rA CNC machine.

HIGH TORQUE STEPPERS

Each axis is controlled by a 57mm, NEMA 23 equivalent high-torque stepper motor. Each fast, device is rated for high duty cycles, and will provide thousands of hours of trouble-free precision.

INDUSTRIAL CONNECTORS

The performance of your machine relies upon accurate transfer of data to the stepper motors. Every wire connector found an an i2rA machine is of the highest quality available. Where available, we use aerospace quality components with metal body, copper terminals, and threaded locking rings.

ONBOARD COOLING SYSTEM

Every i2rA machine offers the option of a liquid-cooled electro spindle.  Our innovative system replicates an automotive cooling system, where a high-volume pump pushes coolant (or antifreeze) through through the electro spindle, and dissipates the heat with a radiator and fan assembly. No buckets, no hoses, no aquarium pumps.  No Drama.

CABLE TRACK CHAIN

A loose bundle of wires almost always results in abrasion, stress and broken leads. Our power and data cables, as well as cooling hoses, are contained within lightweight, flexible nylon track chains to ensure that data is never interrupted by a broken wire.

TOOL TOUCH-OFF SENSOR

Each time you install a bit in your i2rA CNC machine, you’ll need to accurately determine the length of the new tooling. Simply slide the tool touch-off device beneath the bit, initiate the ‘Auto Touch-Off’ command on your UCCNC interface, and the bit length will automatically be determined and stored in the UCCNC software.

PROXIMITY SENSORS

These magnetic sensors act as the CNC’s eyes. They allow you to ‘home’ your machine so it knows where the spindle is in relation to the working envelope.  Noticeably absent in many of our competitor’s machines, these sensors prevent the gantry from colliding with the stops when you run it to the extent of its travel.
