Equipment / CNC Router

CNC Router

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

Summary

Basically this machine imported/modified/upgraded by HPC:

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

Others
