The CNC milling machine has a maximum travel of 250mm x 120mm and a vertical travel of 180mm, the spindle is speed controlled from 0-3000rpm. It's suitable for use with Aluminium, Brass, Mild steel (with caution), stainless steel (very, very slowly) and most Plastics. The Boxford mill requires [[tools/boxford/induction|induction]] before you can use it as it is a complex and challenging to use tool. The boxford is kept downstairs on the west wall between the drill press and the linisher. The lab does not keep a regular stock of milling cutters, although you might find some around the place from time to time. If you have a specific job in mind then it's recommended that you bring your own tooling, we do this because a clumsy operator can easily break hundreds of pounds worth of tools in a few minutes and it wouldn't be fair to other members for the lab to have to pay for that. At the moment we're recommending a maximum speed of 800mm/sec for travel moves (although speeds up to 1000mm/min are available) and 300mm/sec for cutting moves, although the exact speed you want to use will depend on many factors (see the [[Workshops/boxford|induction]]). The boxford is protected from damage by [[Prudence|Prudence, the safety goat]].
