APPLICATION
The Universal Milling Machine is meant to fulfil various milling operations for the
needs of general engineering, which are done through circular, disk-type, form end
milling, gear and other types of cutters.
Various planes, grooves, gear wheels can be machined, it is capable of boring in
steel, cast iron, nonferrous and plastic parts.
The machine can carry out automatic pendulous and semi-automatic linear cycles.
The processing possibilities of the machine can be expanded by using a vertical
milling head, an universal milling head, universal indexing device, rotary index
table, slotting head, rack toothing device and other accessories.

SAFETY PRECAUTIONS
Any type of incorrect use of the machine may result in serious personal injury for
the machine operator. We suggest therewore that the advice and information of-
fered should be througly digested and adhered to as closely as possible so as to
guarantee your saafety and for the operator's safety ass well as to prolong the life-
span of the machine.
GENERAL PRECAUTIONS
* Never leave the machine working without being watched by an operator.
* The operator must be trained to operate milling machines. Training should be
done by manufacturer's or supplier's expert.
* Do not operate this machine without having previously read and fully understood
the safety precautions in this chapter.
* Do not operate this machine without having previously read and fully understood
the Instructions Manual.
* Make sure a supervisor or instructor is present the first time you work this
machine.
* Never attempt to operate the milling machine while your senses are impaired by
medication, drugs, alcohol or other substances.
* Always use safety gear (safety glasses, shoes, etc.)
* Never use gloves which could become caught in the moving parts of the
machine i.e. gloves which are too big and/or are damaged. Only use gloves which
are in good condition and are the right size for the operator. Gloves should also
be used when handling tools / components because they may be sharp.
* Always keep the machine and equipment clean.
* Do not remove nor modify safety systems or their functioning.
* The handle for manual motion of the transversal and vertical feed is to be
removed from the machine before putting on the automatic feed and the rapid
traverse.
* Position yourself at a safe distance from machine so as to avoid getting caught
in the moving parts of the machine. Do not wear watches, rings, necklaces, ties,
etc. and roll up long sleeves to your elbows, long hair should be tied back.
* Provide an adequate light source. If additional lighting is needed do not hesitate
in asking for it.
* Make sure the network voltage corresponds with the voltage marked on the
machine by the manufacturer.

* Be aware of the position of the emergency stop.
* Protect your hands. Stop the main spindle before proceeding to change tools
or workpiece, adjusting a new workpiece, measuring, changing or adjusting belts,
puleys or gears, removing swarf or oil, etc.
* Before starting operation make sure that the workpiece and the cuttters are well
tightened.
* Loose objects on the table may be catapulted into the air. Before starting to
work remove all loose objects such as tools, mandrels, clothes, etc.
* Arrange all tools in order of use.
* Damaged or weakened tools break easily. Keep all tools sharp. Check tools and
toolholder on a regular basis. Insert the tool as far as possible into the toolholder.
* Avoid tool breakage.Use suitable machining feeds and speeds. Reduce speed and
feed when unusual noises are noticed. Avoid unnecessary damage to tool and/or
workpiece. Never start the machine when the tool is touching the workpiece. After
mounting the tool, carry out a trial run. Do not operate the machine in automatic
mode in the beginning.
* Do not use compressed air to clean or remove dust and swarff from the
machine and its surroundings. Use a brush or chip scraper.
* Certain materials, such as magnetisium are highly inflammable in powder or
chip form. Always consult a supervisor before working with these materials.
* Prevent fires. Keep inflamable material and liquid well away from the work area
and hot swarf.
* Make sure the machine is disconnected from the mains before procceding with
any type of repairs or maintenance.
* Maintenance should be carried out by qualified staff.
WARNING: All electrical connections must be performed by a qualified electri-
cian or service engineer.
