Anotace textu normy ČSN EN ISO 19085-3   (496072)

This document gives the safety requirements and measures for numerically controlled (NC) boring machines, NC routing machines and NC combined boring/routing machines (as defined in 3.1), hereinafter referred to as ´machines´.

This document deals with all significant hazards, hazardous situations and events, listed in Clause 4, relevant to the machines when they are operated, adjusted and maintained as intended and under the conditions foreseen by the manufacturer including reasonably foreseeable misuse. Also, transport, assembly, dismantling, disabling and scrapping phases have been taken into account.

NOTE: For relevant but not significant hazards, e.g. sharp edges of the machine frame, see ISO 12100:2010.

This document is also applicable to machines fitted with one or more of the following devices/ additional working units, whose hazards have been dealt with:

- additional equipment for sawing, sanding, edge banding or assembly units and dowel devices,

- fixed or movable workpiece support,

- mechanical, pneumatic, hydraulic or vacuum workpiece clamping,

- automatic tool change facilities.

Machines covered in this document are designed for workpieces consisting of

- solid wood,

- material with similar physical characteristics to wood (see ISO 19085-1:2017, 3.2),

- gypsum boards, gypsum bounded fibreboards,

- composite materials with core consisting of polyurethane or mineral material laminated with light alloy,

- polymer-matrix composite materials and reinforced thermoplastic/thermoset/elastomeric materials, and

- composite boards made from the materials listed above.

This document does not deal with specific hazards related to

- edge-banding equipment fitted to the machines,

- use of grinding wheels,

- ejection from milling and/or sawing tools through openings guarded by curtains on machines where the distance between the workpiece support surface and the lower edge of the partial enclosure exceeds 600 mm,

- ejection due to failure of milling tools with a cutting circle diameter equal to or greater than 16 mm and sawing tools not conforming to EN 847-1:2013 and EN 847-2:2013,

- the combination of a single machine being used with other machines (as a part of a line),

- the necessity to step onto or into the machine body due to its large size, e.g. to adjust clamping elements on machines for wooden walls, and

- integrated workpiece loading/unloading systems (e.g. robots).

This document is not applicable to single spindle hand fed or integrated fed routing machines, machines intended for use in potentially explosive atmosphere, or to machines manufactured prior to its publication.
