1. Safety Requirements and Rules and Regulations
The following requirements must be met before the NC compact vice is put into operation:
The personnel charged with duties related to the NC
compact vice must have read the operating instructions
and in particular the chapter entitled "Safety Require-
ments".
When machining parts, safety largely depends on proper
use and workmanlike handling of the clamping tool.
Unworkmanlike handling and machining may impair the
function of the NC compact vice. Inadequately clamped
workpieces may be flung out of the machine and cause
injuries to personnel.
1. Proper mounting, operation and maintenance are es-
sential requirements.
2. A NC compact vice which is not handled correctly con-
stitutes a potential source of danger.
3. The operator must satisfy himself of the perfect condi-
tion of the NC compact vice before putting it into ope-
ration.
4. Any operation which is not perfectly safe must be
avoided.
5. Any changes affecting the safety of work with the NC
compact vice must be immediately reported by the
operator.
6. Changes or conversions affecting the safety of the NC
compact vice are not permitted.
7. Only the manufacturer's original space parts may be
used for repairs or reconditioning work. All repairs
must be carried out by skilled personnel.
8. The codes of practice and rules for the prevention
of accidents in force in the country of use must be
observed.
9. The applicable European or national regulations for
machinery must be complied with.
10. The general, legal and other mandatory regulations for
the prevention of accidents must be observed in addi-
tion to the operating instructions.
11. The information and recommendations contained in
the operating instructions must be strictly observed.
12. Unless specified otherwise, the work must be always
be clamped by turning the handcrank clockwise. If the
handcrank is turned anti-clockwise, the work is no lon-
ger held securely and constitutes a hazard for person-
nel and the NC compact vice.
13. The vice must always be ble base
which is not easily deformed.
14. The clamps and mounting bolts must be fitted as des-
cribed in the operating instructions.
15. If the vice has not been used for a prolonged period of
time, it must be checked for proper functioning before
it is put into operation. As a rule, this should include a
check of the clamping force and capacity range.
for the Use of Machine Vices
16. The clamping force must be checked with the aid of a
suitable instrument, such as a hydraulic load cell or
an electronic measuring device. The clamping force
measured should not be less than 80% of the specified
maximum clamping force.
17. For NC compact vice with jaws that can be shifted,
sufficient residual clamping travel must be available in
the final position.
18. If the primary energy of hydraulic NC Compact Vices
requiring a pressure intensifier or hydraulic unit should
fail, the clamping force must be maintained at least
until the machine can be stopped or until the tool can
be removed from the working area.
19. Hydraulically operated NC Compact Vices may not be
clamped mechanically.
20. The hydraulic supply lines for the workholding fixture
must be rated for the maximum operating pressure and
protected against mechanical destruction.
21. If the hydraulic NC compact vice is disconnected from
the hydraulic supply line, such as when working with
pallets, for example, the hydraulic system must be
checked for leakage in the disconnected condition be-
fore the vice is put into operation. The pressure must
be maintained at least for the duration of the machining
operation.
22. When clamping the parts to be machined, special care
must be taken to assure full contact of the clamping
surfaces. If this is prevented by excessive errors of
angularity or parallelism, for example, suitable jaws
from the range of accessories offered, such as floating
jaws or special clamping jaws, will have to be used for
compensation.
23. Flexible workpieces and insufficient clamping forces
may cause injuries if insecurely held parts are flung out
of the machine.
The NC compact vice may only be used for clamping
rigid workpieces.
24. The following precautions must be observed when
NC Compact Vices are used which are equipped for
independent force multiplication as a function of travel:
Workpiece stacks or deformed, i.e. not perfectly level
parts, or parts with heavy burr must be mechanically
preclamped (without force multiplication) until they are
no longer resilient before the highpressure force is
applied.
25. Extra high or extra long workpieces must be secured
with the aid of suitable auxiliaries, such as stops or
pads. Special clamping jaws or clamping at several
points may be necessary to avoid vibrations.
