I pulled this safety information from the Boxford website (http://www.boxford.co.uk/boxford/docs/products/t220.htm#safety accessed on 14/01/2011):

Safety equipment features

• Full perimeter guarding with interlocking switches on access doors arranged in the positive (safety) mode for spindle stop and feed hold.
• Overload cut-out on spindle drive.
• Positive end stops on all axes.
• Mandatory graphics run required for new programs before matching cycle can be commenced and step by step execution of graphics in advance of cut in machining cycle.
• Integrated electrical panel with no volt supply protection.
• Feed rate over-ride.
• Feed hold.
• Latching emergency stop button.
• power on indicator lamp.
• Low voltage control circuitry.

I have found that whilst working with this machine that as long as you double check your measurements (stuck-out, billet dimensions etc) and make sure that the work piece is properly secured then you shouldn’t have any problems in manufacture.
