Machine tools safety. Machining centres, Milling machines, Transfer machines. Safety requirements | Status: Current

1 Scope This document specifies the technical safety requirements and protective measures for the design, construction and supply (including installation and dismantling, with arrangements for transport and maintenance) of:

• — milling machines (see 3.1.1), including machines capable of performing boring operations (see 3.1.2);
• — machining centres; and
• — transfer machines (see 3.1.3)

designed for continuous production use, which are intended to cut cold metal and other non-combustible cold materials, except wood or materials with physical characteristics similar to those of wood as defined in ISO 19085‑1 and glass, stone and engineered/agglomerated materials as defined in EN 14618. This document covers the following machines (referred to as "machines" in this document):

1. a) manually, without numerical control, operated boring and milling machines (see 3.2.1, Group 1), e.g. knee and column type milling machines (see Figures C.1 and C.2);
2. b) manually, with limited numerical control, operated boring and milling machines (see 3.2.2, Group 2), e.g. profile and contouring milling machines (see Figures C.3 and C.4);
3. c) numerically controlled milling machines and machining centres (see 3.2.3, Group 3), e.g. automatic milling machines and milling centres, e.g. multi-spindlemilling machines, gear-milling machines (see Figures C.5 to C.7);
4. d) transfer and special-purpose machines (see 3.2.4, Group 4), which are designed to process only pre-specified workpieces or limited range of similar workpieces by means of a predetermined sequence of machining operations and process parameters (see Figures C.8 to C.13).

1. e) machines fitted with the following devices/facilities, whose hazards have been dealt with:
   • — tool magazine(s);
   • — tool changer(s);
   • — workpiece handling mechanism(s);
   • — powered workpiece clamping mechanism(s);
   • — swarf/chip conveyor(s);
   • — power-operated door(s);
   • — moveable operator cabin(s);
   • — additional equipment for turning;
   • — additional equipment for grinding.

This document deals with all significant hazards, hazardous situations and events relevant to this type of machinery which can occur during transportation, assembly and installation, setting, operation, cleaning and maintenance, troubleshooting, dismantling or disabling according to ISO 12100, when the machinery is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This document presumes accessibility to the machine from all directions and specifies access conditions to operator positions. It also applies to workpiece transfer devices including transport devices for loading/unloading when they form an integral part of the machine.
