Equipment / CNC Router
On Order, Not yet installed : Our 1200x1200/4'x4' CNC Router
Contents
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

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
Original Requirements Notes
- CNC Controlled
- Minimum 4' x 4' cutting bed
- It was generally concluded whilst 8' x 4' would be attractive, it may have limits in terms of floor space and also materials storage and handling - storing and moving 8' x 4' sheets on to a flatbed machine is a pretty impractical task in a full workshop, and certainly not a 1 man job.
- We concluded we could store a lot of sheet material in 4' x 4' and 600 x 900 for the router and laser respectively (and for general use), making storage much more tractable and avoiding the need to cut down such large sheets.
- decent software
Maybe a Vacuum bed
- Would make jobs quicker to setup (except vacuum beds sometimes require a custom 'mask' cutting to cover all the unused holes)
- avoids risk of hitting clamps/bolts
- Will be more expensive (new mask needed for each job?)
- Unsure how "magical" a solution it is
Options
Shopbot
- The defacto FabLab CNC router
- Would be from the [PRS Standard Range]
- Prices are roughly $11500 and $13000 for the 4x4 and 8x4 models
- Ship from US (no distributors), by air or sea, and import duties etc payable
- Quote from Shopbot: approx $15k/£10k + shipping/taxes for 4x4, 8x8 would be approx £2k more
Piranha
- Look like imports, sold by radecal
- Include internal vacuum bed
- Available in 4x4 and 4x8. 4x4 and 4x8 both listed as weighing 800kg.
- 4x8: http://www.radecalmachinesales.com/product.asp?cid=2&scid=&pid=18
- 4x4: http://www.radecalmachinesales.com/product.asp?cid=2&scid=&pid=70
- Quote from radecal: TBC (guessing about £13k and £18k)
HPC Laser CNC
- Not clear what is available or specs; assume it is china import again, but could be interesting to go with HPC given great service
- 1200x1200 looks like it might be: http://www.ebay.co.uk/itm/HPC-CNC-router-1200-x1200-engraver-CNC-Machine-sign-making-UK-stock-/150966295622
