Electro-permanent magnetic chuck ALUSTAR

circularfor grinding

The Alustar permanent chuck is used during turning and grinding of ring-shaped workpieces. The chuck excels due to its low weight resulting from the aluminium design of the body. It can cope with a larger weight range of machined components. With this chuck, you have the possibility to machine the front, inner and outer diameter of the workpiece in one operation. The possibility of continuous control of the holding force facilitates centring. Advantages: Compact top plate made of one piece of steel with radial poles High performance magnetic system with neodymium magnets Unique construction with a self-locking switch mechanism for continuous adjustment of the holding force facilitating workpiece centring Aluminium base reduces the load on the machine tool spindle and increases the available weight capacity of workpieces Very safe, self-locking mechanism preventing the chuck from switching off during machining A recess and threaded holes on the underside of the base for clamping to a suitable flange Detailed description: The Alustar permanent magnetic circular chuck is a lightweight version of the Neostar chuck. The aluminium body reduces its weight significantly thereby allowing clamping of workpieces with larger weights than the basic Neostar version. The great advantage of the chuck is the patented switch mechanism, which makes it possible to adjust the holding force variably and fix the adjusted holding force in any position Thanks to the switching mechanism, you can switch the chuck to 10 to 20 % power to centre the workpiece easily, then switch to 100 % and proceed with safe operation.
