We are looking at performing a CNC conversion kit on the mill in the space

The item

  • CNC Fusion X2 conversions - Kit #4 at $559 (approx £354)- excludes motors, controller. Requires no physical changes to the mill so can be easily reverted. This kit provides 3 axes of control with upgraded ballscrews - presumably to reduce backlash.
    • Motors/Controller/Software must be purchased separately.
    • The ballscrews are imperial - but this shouldn't matter

From CNCFusion:

 Hi Elliot, from the specs listed, I believe the ChesterUK mill is the same as this one...
 http://www.littlemachineshop.com/3900 the specs are the same, maining travels and table
 width. There is an option at bottom right of X2 page, to add an LMS High Torque upgrade.

Budget estimation

(Note: the parts in this section were looked up by bluekieran, who doesn't know anything about this stuff, just to help estimate the total budget.)

Specification

  • Must be reversible - so that we can potentially return the mill in the condition that it was lent to us. It doesn't have to be in the same condition, merely still usable without the CNC, drilling mounting holes etc. is fine. Nigle
  • Axis: 3 would be a good starting point. But it would be a good idea if the chosen electronics had the capability of driving the rotary table and controlling spindle speed at a later date without having to be replaced. Nigle
  • Max purchase cost: £?
  • Construction: A kit solution looks best. Otherwise we'd need to machine adapters and various parts to couple the mill with the motors - harder still if we want to avoid modifying the mill itself.

Mill

Kits that we considered

  • KDN conversion kit. - Requires modification of the mill. I have no problem with that modification, if this is the best kit then go for it! Nigle
  • Plans for X2 conversion - Not free - It will be a lot of work to convert the mill ourselves so we should probably just stick to a pre-fabricated kit.
