SCHUNK is now offering a freely programmable and universally applicable magnetic switch with ATEX certification for device group II, category 2 for monitoring gripping systems in potentially explosive areas. The MMS 22-PI1-EX has a freely programmable switching point and detects a magnet inside of the actuator. It can be placed directly in the C-slot of the gripping or rotary modules with no interfering contours. Instead of time-consuming mechanical adjustment of the switching point, the magnetic sensor can be programmed in just a few steps. The required magnetic teaching tool is included in the scope of delivery. An optional plug-in teaching tool is also available. The corresponding switching condition is indicated on an LED display. Thanks to the standard plug connector, the sensor can be easily connected with standardized connection cables.
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 Tübingen-based premium-tool manufacturer is now expanding its thread milling cutter range. Three new thread milling cutter inserts with smaller corner radii enhance the versatility of the existing tool bodies; two new bodies now allow M56 and M64 coarse-pitch threads to be cut. These new additions transform the thread milling cutter family from one that was focused primarily on productivity to a family that can now be used universally.
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.
To enhance milling performance on ISO S materials, cutting tool and tooling system specialist Sandvik Coromant is introducing a series of end mills featuring unique geometries and grades. The CoroMill® Plura HFS (High-Feed Side milling) ISO S cutters deliver reliable and productive results on workpieces made from titanium and nickel-based alloys, bringing benefits to both aerospace engine and frame applications.
In the future, the high-precision SCHUNK TRIBOS polygonal clamping technology will also be used for lathes and automatic revolving transfer machines. SCHUNK, a competence leader for gripping systems and clamping technology, has developed special polygonal toolholders with ER cone for this purpose, which can be combined with all commercially available mountings for ER collets and with driven tools in particular.
