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):
-
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);
-
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);
-
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);
-
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).
-
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.
