1.2.2 Intended application
Purpose
Machining of shafts by:
–deep hole drilling with BTA (push boring/pull counter boring/roller bur-
nishing/skiving)
–Deep-hole drilling with single-lip drilling (ELB)
–Bottle boring
The machine is not suitable for any other applications.
Every constructional modification of the machine to use it for other purposes
is permitted only after consulting and approval by TBT - Tiefbohrtechnik
GmbH+Co. Only workpieces determined for the respective application may
be machined.
It is forbidden to make any modifications of safety-relevant components
without written approval by TBT - Tiefbohrtechnik GmbH+Co. The safety
responsibility of the manufacturer (product liability) otherwise becomes void.
Machining is permitted only within the power limits. For this, the specifica-
tions in the section Technical Data (section 1.3) are authoritative.
1.2.3 General hazard potential with this machine
The machine was developed, designed and built according to technical safety as-
pects. Usage contrary to that intended or usage by unqualified personnel may result
in danger
to life and health of the operator
to the machine itself
to other property of the operator
to the performance of the machine
and consequently to its economy.
Should the work sequence and intended use of the machine allow for it, all hazard
points must be clad as to prevent danger for life or limb of the operating personnel
during proper and careful handling. During operation it is not necessary and there-
fore prohibited to tamper in the working area or remove protective devices in order
to be able to interfere with the operation.
On machines, where for contractual reasons it was possible to provide a protective
device not corresponding to the EC directives (e.g. attachment of clamping/loading
devices, etc. by the customer), the end customer shall be responsible for the provi-
sion of guards or other safety devices as part of the overall safety of the system.
These devices and safeguards must correspond to the applicable EC directives.

The general hazard potential in improper and careless use of the machine consists
of:
Mechanical danger through
impact, due to the kinetic energy of the moving masses
pinching, shearing and cutting
grabbing and wrapping and drawing-in
penetration or piercing
sharp edges and corners
fluids under pressure
freely movable parts.
Electrical danger through
electrical contact (direct or indirect).
The plant is equipped with an overcurrent protective device according to EN 60204.
It prevents that the plant will be damaged and persons be endangered in case of
short circuits. It is compulsory to always use original fuses (with the appropriate re-
sponse time and amperage).
Combination of dangers through
faulty assembly
incorrect clamping of tools
tool wear
failure and/or incorrect application of protective measures.
Danger through centrifuges
The electro-automatic cover lock or screwed covers must only be opened if drum
is out of operation. Do not climb on the centrifuge during operation, do not reach
into the feed opening or poke in it with other items.
Danger due to laser radiation
The machine is equipped with a laser unit / optical sensors:
Avoid any contact with your eyes!

Danger through pumps
Protective devices and mountings may only be removed when
the pumps are emptied,
motors and driven machines are stationary,
the plant is electrically dead and protected against restarting.
Danger through emission
The equivalent continuous sound pressure level of the deep-hole drilling machine
is less than _ see Noise level measurement report _dB(A).
Any generated oil mists, depending on the oil grade used, have the danger class
according to the respective safety data sheet (DIN 52900).
do not inhale oil mist!
Oil mist is harmful and may contain carcinogenic substances
Hydraulic oils and lubricants may easily cause slipping on the floor and in the plant.
For reasons of accident prevention, therefore, irreproachable cleanliness must be en-
sured when handling these liquids.
Danger through fluids
The plant is operated with materials which can pollute water. The plant operator
is responsible for complying with the regional and national statutes (e.g. water re-
sources act).
Pay attention when using hot process materials (burn hazard).
Fire protection
Keep combustible and easily flammable substances away from the working area.
Combustible substances are:
Paper
Cleaning rags
Oil
Naphtha or colours.
In contact with oils, greases and glycerines oxygen leads to explosion.
