CNC Router


Summary

A CNC router is a computer controlled shaping machine. These are related to the hand held router. Instead of hand held routing, the tool paths can be controlled via computer numerical control. It is a computer-controlled machine for cutting various hard materials, such as wood, composites, aluminum, steel, plastics, and foams. It is one of many kinds of tools that have CNC variants. A CNC router is very similar in concept to a CNC milling machine. The CNC router is controlled by a computer. Coordinates are uploaded into the machine controller from a separate CAD program

  • Capacity: 1200 x 1200 x 120mm
  • Rate (X,Y): 6000mm/min (Max) 5000mm/min (Working)
  • Rate (Z): 30mm/sec
  • Spindle Speed: 4500 to 24000rpm
  • Mechanical Precision: 0.01mm
  • Spindle Power: 1.5KW Variable Speed, Water-cooled
  • Blade Diameter: min 3.175mm, max 12.7mm
  • Order Format: HPGL, G code, u00, mmg, plt
  • Control System: DSP with USB connection

Here are some examples we've made on the CNC router (please add a photo of yours any time you do a job!)

Using the CNC Router

Owners

The Owners are those who have volunteered to be in charge of the equipment, organising maintenance, training others to use it, and generally being a point of contact. The current Owners of the CNC Router are:

  • Stephen Woolhead
  • Chris Abri
  • Mark Mellors
  • Dave Ansell
  • David Bebb
  • Simon Stirley

If you have any questions, problems or concerns around the CNC router, please use the mailing list thread:

Training

YOU CAN ONLY USE THE CNC ROUTER IF YOU HAVE BEEN TRAINED
and have been added to the Trained Users list by one of the Owners

To get trained on the CNC router and be added to the qualified user list, you will need to arrange for a training session with one of the Owners.

If you'd like to arrange training, please see:

Health and Safety

The CNC Router is a potentially dangerous piece of equipment which must only be operated by members who have received appropriate training and who take due care. The top things to always remember when using the CNC Router are:

  • ONLY USE THE CNC ROUTER IF YOU ARE ON THE LIST OF TRAINED USERS
  • NEVER LEAVE THE CNC ROUTER RUNNING UNATTENDED

As a trained user, you should be very aware of the following risks and how to deal with them:

FIRE - Cutting with the wrong settings could result in the material igniting.

TRAPPING - Stand clear of the machine while in motion.

DUST - Ensure extraction system is working.

NOISE - Ensure that you wear the correct PPE when working with the machine for prolonged periods.
