Those wanting to turn, mill or grind rings, flanges, housings or other thin-walled parts will quickly reach the limits of what is possible using conventional chucks or face plates: the parts are deformed in the clamping process, shaping and geometric tolerances are difficult to adhere to and the interference contours of the clamping devices restrict the accessibility. There are a great deal of alternatives here – from the compensating multi-jaw chucks, the magnetic clamping technology right up to the pendulum jaws. To ensure things run smoothly, it is worth knowing the strengths of the individual problem solvers, because this saves time, money and often nerves.
The family of manual SCHUNK KONTEC KSC Basic-Line is known for high clamping forces, ease of use, short set-up times and excellent price-performance ratio. SCHUNK, the competence leader for gripping systems and clamping technology is now expanding its modular system with the SCHUNK KONTEC KSC-D, a lightweight and flat double clamping vise especially designed for demanding applications in automated machine tools with workpiece storage.
German clamping tool specialist BESSEY is providing an extensive range of information on self-adjusting toggle clamps on its new microsite in 12 languages. Designers, craftsmen and buyers can find technical details and interesting facts about the unique range of accessories as well as exciting excerpts from the history of the range.
In many production facilities, Weldon tool holders are used as the standard chuck for solid carbide milling cutters. However, the design of this type of chuck limits its application. Indeed, the tolerances of the fit for the tool adapter are high (at a clamping diameter of 20 mm, the maximum clearance is already 22 µm). This results in a large run-out error that causes imbalance, as well as wear on one side of the tool, creating adverse effects on machining quality.
Constant clamping forces, minimal maintenance costs as well as high energy efficiency, and productivity are assured with the versatile SCHUNK ROTA NCA power lathe chuck. With its large dimensioned through-hole for automated bar loading and its convenient clamping range, the weight-reduced lathe chuck covers an extremely wide range of applications.
The hydraulic compensation jaws from SCHUNK, the competence leader for gripping systems and clamping technology, set a new benchmark in hydraulic compensation jaws for low-deformation workpiece clamping. It is the first time that chuck jaws for compensating the workpiece clamping have successfully been combined with centrifugal force compensation, vibration-damping characteristics and micron-precise concentricity.
Uncontrolled vibration creates multiple problems in metalcutting operations. Varying forces in the cutting process cause vibration and tool chatter that degrade part surface quality, quickly wear or break cutting tools and damage machine tool components. Trends in product design can also incite vibration.
“Industrial production is on the verge of a fundamental change,” underlined Dr. Markus Klaiber, Chief Technology Officer/CTO of SCHUNK GmbH & Co. KG in Lauffen, Germany with a view to EMO 2017. “In the years ahead, the digitalization, use of mechatronic products, and automation of production processes, collaboration between humans and robots as well as intelligent networking of all process-relevant components will promote a new concept of industrial production.”
Ever-shortening product life cycles, the trend towards automation and development leaps in the field of peripherals lead to individual processes as well as entire machine and system concepts being made available today much earlier than was the case a few years ago. In order to keep up with the market, the equipment in particular offers…
The SCHUNK VERO-S quick-change pallet modules offer a whole bundle of advantages for users when it comes to direct workpiece clamping without interfering contours: free 5-sided access to the workpiece, a defined clamping situation, high repeat and positioning accuracy, as well as high pull-down forces for challenging operations. SCHUNK further extends its modular system for workpiece direct clamping in order to ensure that the efficient principle will also work in the field of tool and mold making industries for free-form parts with complex geometries, small lot sizes, and high precision requirements.
