Description of 20/30378684 DC 2020

This document gives the safety requirements and measures for numerically controlled (NC/CNC) boring machines, NC/CNC routing machines and NC/CNC combined boring/routing machines (as defined in 3.2 and 3.3), designed for continuous production use, hereinafter referred to as "machines".

This document deals with all significant hazards, hazardous situations and events, listed in Annex A, 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.

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:

1. additional working units for sawing, sanding, edge banding, assembling or dowel inserting;

2. fixed or movable workpiece support;

3. mechanical, pneumatic, hydraulic or vacuum workpiece clamping;

4. automatic tool change devices.

Machines covered in this document are designed for workpieces consisting of

1. solid wood,

2. material with similar physical characteristics to wood (see ISO/DIS 19085-1:2020, 3.2),

3. gypsum boards, gypsum bounded fibreboards, cardboard,

4. matrix engineered mineral boards, silicate boards,

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

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

7. aluminium light alloy profiles,

8. aluminium light alloy plates with a maximum thickness of 10 mm,

9. composite boards made from the materials listed above.

This document does not deal with specific hazards related to

1. edge-banding equipment fitted to the machines,

2. use of grinding wheels,

3. ejection through openings guarded by curtains on machines where the height of the opening in the enclosure above the workpiece support exceeds 600 mm,

4. 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 847-1:2017 and EN 847-2:2017,

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

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

This document is not applicable to:

1. single spindle hand fed or integrated fed routing machines,

2. machines designed to process aluminium light alloy only,

3. machines intended for use in potentially explosive atmosphere,

4. machines manufactured prior to its publication.
