Work should not start until the risk has been reduced
which may require considerable resource allocation. If
work is in progress urgent action must be taken
Work must not start until the risk has been reduced to an
acceptable level. If it cannot be reduced then the work
must remain prohibited

Description
This Milling Machine is predominately used for cutting metals and less often materials such
as nylon. It is used for a range of one off machining, cutting and shaping. Specialist tasks and
skills are required for each individual setting up system.
System
The milling machine is ONLY to be used by appointed/inducted person(s) . The workshop
Technical Demonstrators provides training and assistance to operate the machine.
Before using the milling machine ensure that it is suitable for the task in hand, with
appropriate mounting devices/ chucks/ mounting plates, tools.
All guards must be in place and chuck keys removed.
Check the operation of the emergency stop controls before setting up the work.
The machine must be electrically isolated before carrying out any setting up or adjustm ents.
Cutting tools should be in good order and user should be inducted on their correct use.
Cutters should be should be correctly fitted in chuck and rigid.
Cutting feeds and speeds must be calculated to suit the material being machined and the
size and type of tools being used.
Particular attention must be paid to secure mounting of work pieces on traversing bed.
When cutting metal is will be more than likely that a cutting coolant will be
necessary to assist with the process. The coolant reservoir will need checking and
the drain hole clear of any swarf. Coolant spillage could result in a slip hazard, to
help prevent this direct coolant flow to eliminate spillage where possible and use
spillage mat (Pigmat) to soak up excess coolant.
Always wear the appropriate PPE, which will include high impact eye protection/full face
shield. Dust masks may be appropriate when machining some woods. Gloves and loose
fitting clothes must not be worn during the operation as they can become snagged and draw
the operator into the machine.
Keep the immediate work area clear of obstructions and maintain high standards of
housekeeping.

Manual handling
Materials milled on the machine can be small but heavy. Special care must be taken in
multiple, repetitive tasks that can include twisting and overstretching.
Control of Substances Hazardous to Health (COSHH)
The cutting coolant that are used in the operation of the machine are documented in the
COSHH file. The substances used do not present a health hazard when used correctly.
However , care must be taken to minimise the risk of spillage and of splashes to the face and
eyes.
Electrical Integrity
The machine was fitted in accordance with The Provision and Use of Work Equipment
Regulations 1998 (PUWER). It is maintained by a competent person on a regular basis. The
isolation switch is next to the machine for maintenance work or in case of an accident.
