This document does not deal with the specific hazards of edge banding equipment fitted to NC boring
machines, NC routing machines and NC combined boring/routing machines.
This document is only applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are designed to use milling tools with a cutting circle diameter below 16 mm or
milling tools or saw-blades conforming to EN 847-1:2005+A1:2007 and EN 847-2:2001 and boring tools or
sanding wheels.
This document is not applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are designed to use grinding wheels.
This document is not applicable to single spindle hand fed/integrated fed routing machines.
NOTE Single spindle hand fed/integrated fed routing machines are dealt with in EN 848-2:2007+A1:2009.
This document does not deal with the specific hazards of ejection through openings on machines where the
distance between the work-piece support and the lower edge of the partial enclosure exceeds 400 mm.
This document is not applicable to NC boring machines, NC routing machines and NC combined
boring/routing machines which are manufactured before the date of its publication as EN.
