Turning

Permanent neodymium magnetic chucks are indispensable aids for turning workpieces, primarily of a circular shape. The advantage of circular chucks is that you can machine the face, inner, and outer diameter of the workpiece in a single operation. The clamping surface forms a single unit. Thanks to the high speed of workpiece change, you achieve a more efficient production process.

Our customers have become fond of the Neostar circular clamping magnet, for which you can choose central drilling, a precise centering hole, an additional pole plate, a pole plate with T-slots, or a set of pole extensions. The lightweight version of this neodymium chuck is Alustar, whose body is made of aluminum. This gives you the same clamping force with lower weight.

    Alustar permanent magnetic chuck

    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. The long life span of the permanent magnetic chuck is ensured by the solid single piece top plate. Possibility to regrind by up to 5 mm. It is possible to deliver this chuck with a through-hole by request. Important parameters: Application: Turning, grinding Technology: Permanent Holding force: 140 N/cm2 Poles: Radial Regrinding limit: 5 mm Guarantee: 2 years Additional information: Beyond the standard design, the customer can choose: Central drilling Precise centre hole (possibly through) Auxiliary top plate Pole plate with T-slots Set of pole extensions Scope of supply: Magnetic chuck Ratchet wrench Instructions for use Use: Turning and grinding of round and ring-shaped workpieces Parameters: Model D (mm) H (mm) D1 (mm) E (mm) F (mm) Hmotnost (kg) ALUS20D200 200 79 20 110 180 11,5 ALUS20D250 250 79 30 166 220 18 ALUS20D300 300 82 38 180 260 27 ALUS20D350 350 84 40 220 300 36 ALUS20D400 400 84 40 260 340 47 ALUS30D500 500 109 50 330 400 98 ALUS30D600 600 109 90 350 450 142

    Neostar permanent magnetic chuck

    Detailed description: The Neostar permanent magnetic chuck is especially designed for clamping workpieces for turning and circular grinding. The top plate with radial poles allows easy and efficient machining of the front, inner and outer diameter of the workpiece in one operation – without the need to release and re-clamp it. It features a maximum holding force up to 140 N/cm2 – depending on the chuck size and dimensions of the workpieces to be machined. The robust steel base is provided with 2 – 4 threads on the bottom for attachment to a suitable flange. Important parameters: Application: Turning, circular grinding Technology: Permanent Holding force: 140 N/cm2 Poles: Radial Regrinding limit: 5 mm Guarantee: 2 years Additional information: You can select centre drilling, a precise centre hole, an additional top plate with T-slots or a set of pole extensions. If you have any questions or if anything is unclear, we will be happy to advise you. Use: Turning and grinding of round and ring-shaped workpieces Facing work, internal and external diameter machining is possible separately or in one operation Scope of supply: Magnetic chuck Allen key Certificate Instructions for use Parameters Model D (mm) H (mm) D1 (mm) E (mm) F (mm) Weight (kg) Number of poles NEOS130 130 57 15 - 100 5 10 NEOS150 150 57 15 80 120 7,3 10 NEOS200 200 57 20 110 180 13 12 NEOS250 250 70 30 140 220 25 16 NEOS300 300 73 38 180 260 37 16 NEOS350 350 73 40 220 300 49 20 NEOS400 400 74 40 260 340 68 20 NEOS500 500 78 50 300 400 109 24 NEOS600 600 78 90 350 450 172 30 NEOS700 700 78 90 350 450 234 30 NEOS800 800 110 100 400 700 420 30

    Electro-permanent circular magnetic chuck Circu EP

    Detailed description: The Circu EP is an electro-permanent magnetic chuck designed for installation on rotary tables of vertical grinders for clamping of tool and hardened steels and for heavy duty turning operations. The radial layout of the individual poles is suitable for work with circular or cylindrical shapes such as bearing rings, circular rings, bushings, etc. Using the control unit, the holding force can be controlled in several steps and fast and efficient demagnetization of workpieces can be performed. Thanks to the electro-permanent technology used there is no need for permanent connection to the mains. This results in high efficiency in operation and this also ensures the highest possible clamping accuracy. Important parameters: Technology: Electro-permanent Poles: Radial Regrinding limit: 8 mm Guarantee: 2 years Additional information: High holding force for clamping during the ultimate heavy duty machining, drilling, and turning operations. Available with pole plate equipped with T-slots for mounting pole extensions. The control unit can be programmed for different types of material to achieve maximum strength and effective demagnetization after machining. At the same time, it is possible to adapt the force to clamp even thinner parts without any deformation. The chuck can be connected via the slip ring in the machine tool spindle, or through the connector located directly on the magnetic chuck. Use: circular grinding, roughing, turning Catalog number D (mm) H (mm) Weight (kg) Voltage (V) Circu EP 400 400 90 76 170/340 Circu EP 500 500 90 120 170/340 Circu EP 600 600 100 195 170/340 Circu EP 700 700 100 265 170/340 Circu EP 800 800 100 365 170/340 Circu EP 1000 1000 100 550 170/340 Circu EP 1250 1250 123 990 170/340 Circu EP 1500 1500 120 1550 170/340
