Safety of woodworking machines - One side moulding machines with rotating tool - Part 2: Single spindle hand fed/integrated fed routing machines

This document specifies all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable single spindle hand fed/integrated fed routing machines with fixed head but allowing only movement along the axis of the tool during machining hereinafter referred to as "machines" designed to cut solid wood, chip board, fibreboard, plywood and also these materials if they are covered with plastic laminate, edgings or veneer when they are used as intended and under the conditions foreseen by the manufacturer. This document does not apply to inverted pin routers and radial arm routers (machines where the work piece is fixed and the tool head is manually moved); NC boring machines and NC routing machines; hand-held routers or any adaptation permitting their use in a different mode, e.g. bench mounting; routing machines set up on a bench or a table similar to a bench, which are intended to carry out work in a stationary position, capable of being lifted by one person by hand. The bench can also be an integrated part of the machine if it consists of hinged legs which can be extended down. This document is not applicable to single spindle hand fed/integrated fed routing machines which are manufactured before the date of its publication as EN.

This document specifies all significant hazards, hazardous situations and events as listed in Clause 4 which are relevant to stationary and displaceable single spindle hand fed/integrated fed routing machines with fixed head but allowing only movement along the axis of the tool during machining hereinafter referred to as "machines" designed to cut solid wood, chip board, fibreboard, plywood and also these materials if they are covered with plastic laminate, edgings or veneer when they are used as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse.
For the definition of stationary and displaceable machine see 3.2.17 and 3.2.18.
Machines which are designed to work wood based materials may also be used for working hardened plastic materials with similar physical characteristics as wood.
This document does not apply to:
a)   inverted pin routers and radial arm routers (machines where the work piece is fixed and the tool head is manually moved);
b)   NC boring machines and NC routing machines;
NC boring machines and NC routing machines are dealt with in EN 848-3:2007+A1:2009.

Ta dokument določa vsa večja tveganja, nevarne razmere in dogodke iz točke 4, ki se nanašajo na stacionarne in premestljive enovretenske navpične rezkalne stroje z ročnim/mehanskim podajanjem s fiksno glavo, ki dovoljujejo le gibanje vzdolž osi orodja med strojno obdelavo, v nadaljnjem besedilu »stroji«, ki so namenjeni za rezanje polnega lesa, ivernih plošč, vlaknenih plošč, vezanih plošč in teh materialov, če so prekriti s plastičnim laminatom, robovi ali furnirjem, kadar se uporabljajo v skladu z namembnostjo in pod pogoji, ki jih predvidi proizvajalec, vključno z razumno predvideno nepravilno uporabo. Za definicijo stacionarnega in premestljivega stroja glejte 3.2.17 in 3.2.18. Stroji, namenjeni za obdelavo materialov na osnovi lesa, se lahko uporabljajo tudi za obdelavo trdih plastičnih materialov, ki imajo podobne fizikalne lastnosti kot les. Ta dokument ne velja za: a) invertne rezkalnike in ročne radialne rezkalnike (stroje, kjer je obdelovanec pritrjen in se glava orodja premika ročno); b) numerično krmiljene vrtalne in rezalne stroje ter kombinirane numerično krmiljene vrtalne/rezalne stroje, ki so obravnavani v EN 848-3:2007+A1:2009; c) ročne rezkalnike ali kakršno koli prilagoditev, ki omogoča njihovo uporabo na drugačen način; d) rezkalne stroje na delovni mizi ali njej podobni mizi, ki so namenjeni delu v stacionarnem položaju in jih lahko z roko dvigne ena oseba. Delovna miza je lahko sestavni del stroja, če ima noge na tečajih, ki jih je mogoče razširiti navzdol. Ta dokument ne velja za enovretenske navpične rezkalne stroje z ročnim/mehanskim podajanjem, ki so bili izdelani, preden je bil objavljen kot standard EN.

foreseen by the manufacturer #including reasonably foreseeable misuse$.
#For the definition of stationary and displaceable machine see 3.2.17 and 3.2.18.
Machines which are designed to work wood based materials may also be used for working hardened plastic
materials with similar physical characteristics as wood.$
This document does not apply to:
a) inverted pin routers and radial arm routers (machines where the work piece is fixed and the tool head is
manually moved);
b) NC boring machines and NC routing machines;
#NC boring machines and NC routing machines are dealt with in EN 848-3:2007+A1:2009.$

d) routing machines set up on a bench or a table similar to a bench, which are intended to carry out work in
a stationary position, capable of being lifted by one person by hand. The bench can also be an integrated part
of the machine if it consists of hinged legs which can be extended down.
#NOTE 2$ Transportable motor-operated electric tools are dealt with in EN 61029-1:2000 together with
#EN 61029-2-8:2010$.

routing machine
C-frame type machine for the moulding of workpieces by means of:
-1
a) one tool spindle located above the table and running at speeds between 6 000 min and generally
-1
24 000 min . The work head is tiltable or not and may be movable only along the direction of the axis of
the tool during machining;

and/or adjustable round the C axis;
c) the tool spindle/work head is either manually or power driven moved vertically during machining or moved
by means of hydraulic or pneumatic devices. The workpiece is normally fed to the machine in a direction
opposite to the direction of the tool spindle either manually or by means of an integrated feed system

shaped work
machining of a curve at the edge or on the surface of a workpiece
NOTE 1 One of the techniques is attaching the workpiece to a jig. On the underside of the jig is a template which is in
contact with a reference pin located in the centre of the table directly below the cutter. The jig is moved past the pin, but in
contact with it, thereby reproducing the shape of the template on the workpiece (see Figures 3 and 4).
