Function
FORKARDT SKM devices contain a force receptor and processor-driven
electronics with sophisticated software. The various functions
are suitable for every day measuring and checking gripping forces
of chucks.
The meters' microprocessor multiplies the level of jaw power by
the previously selected number of jaws to give the total jaw force
of the chuck. The results displayed by the device give you the
safety to decide whether the workpiece can safely be gripped.
Previous settings remain stored in the meter when it is switched
off. Upon switching it back on measuring operations can be started
immediately. Rechargeable power cells in the meter and a main
adapter allow problem-free and mobile use.
The ergonomic casing is made from aluminium. Its robust construction
ensures usage even under rough production conditions in modern
machining.
Usage
The utilisation of modern CNC lathes and new cutting tool materials
allows for ever increasing cutting speeds, thus considerably improving
machine efficiency and productivity. High precision and quality
chucking equipment from FORKARDT provide the gripping forces necessary
to transmit the power to the workpiece, maximising accuracy and
high speeds offered by the machine.
To ensure safety when machining, the European Norm EN 1550 clearly
states that the operation of chucks should be regularly checked
by measuring the static gripping forces. Utilizing FORKARDT SKM
gripping force meters can satisfy this requirement. The SKM 1200
and SKM 1500 gripping force meters can be used to:
- check the safety of the chucking operation for high cutting
speeds and feeds
- focus and optimise the use of the workholding fixture
- measure the gripping force of the chuck relative to the number
of jaws without moving the jaws out of alignment
- determine the chuck factor (i.e. the ratio of gripping force
to axial force or adjusted pressure)
- monitor lubrication of the chuck
- determine lubrication intervals for safe chucking
- provide information regarding preventative chuck servicing
- save energy, reduce stress, wear and tear on the chuck and minimise
distortion of the workpiece through focused interpretation of
dynamic gripping force (Fsp0)
The FORKARDT SKM meters are solely for testing stationary gripping
forces at idle chucks.
Furthermore, the measured levels of gripping forces should always
be compared to the values quoted in the relevant chuck operators
manual. By this, the expected loss of gripping force can be determined,
especially when operating chucks at highest rotational speeds. |
