Manual chucks are standard equipment in optical and tactile measurement technology, including in the modular system of dk’s fixing programmes. This product range has now been expanded specifically for optical measurement technology to include precise manual four-jaw chucks.
In general mechanical engineering, the following two main tasks are assigned to the centric closing four-jaw chuck:
» Clamping square material
» Clamping workpieces that are sensitive to deformation
In the field of optical metrology, however, there is another important factor to consider:
» View through the centre of the four-sided feed
Optical metrology has an easy job when parts are inspected in transmitted light or, generally speaking, when there is a clear contrast to the surroundings. However, a standard three-jaw chuck always places one jaw in the background at the clamped end of the test piece – this scenario is not ideal.
The ideal solution, on the other hand, is to leave as much space as possible behind the end of the centre axis of the workpiece – as is the case with the four-jaw chuck.
» The optional standardised SWA39-interface, which makes the jaw chuck adaptable to all quick-release holders, mounting and adjustment elements of the dk modular system
» An integrated pin hole and three sets of pins of different lengths, which enable the workpiece to be held above the jaws
» Tool-free reversible jaws
» Delivery of suitable jaw blanks for customer processing for special workpieces and processes
