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.
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.
