6. March 2011: Activities of Walker Hagou Magnetics are acquired by SAV The activities of the company Walker Hagou Magnetics BV from Bladel, The Netherlands, have per the 4th of March been completely acquired by the German company SAV Spann-Automations-Normteiletechnik GmbH from Nuremberg. The activities of Walker Hagou Magnetics BV are continued under the name SAV Walker Hagou. Thanks to this acquisition and the continuation with a substantial part of the former staff, SAV has secured the available knowledge and experience and at the same time her market position in magnetic workholding and standard products is further extended and strengthened. This acquisition also leads to the existing product group Heavy Lifting being added to the product program of SAV. For many years, Walker Hagou Magnetics was a sub supplier to SAV for standard magnetic products and a co-operation was already discussed several times. The new company SAV Walker Hagou is now a full daughter of the SAV Group and thereby has a new and strong foundation with which we are confident for the future. |

October 2010: SAV Mechatronic chuck SAV offers the clever combination of an electro-permanent magnetic chuck with an integrated 6-Jaw mechatronic chuck. This innovative workholding concept is applied for the automation of machine tools, for precision centering with high repeatability in either OD- or ID axial clamping. Without resetting it allows for a combination of high power chip removal in the first setup and finishing in the second. Unique is the clamping of eccentric parts at different orientations to the spindle centre. Totally the working principle allows for 6 different clamping setups. The core of the chuck is the enhanced magnetic system with optimized pole setup and real poles for minimum field heights. The 6 fully integrated linear axes are made out of servo actuators with integrated brake and a measuring system with a resolution of 0.0025 mm. At a chuck diameter of 1000 mm, the stroke per axe is 50 mm, optionally with quick change jaws. For such a chuck size, the holding forces lie with approx 300 daN per actuator. The mechatronic chuck can be provided from diameter 850 mm with a height of 165 mm. This size provides a minimal magnetic range of 350 mm. Larger size chucks are available up to 3000 mm from one part. First market introduction at the AMB 2010 in Stuttgart. |

September 2008: High precision demands in the roller bearing industry To achieve optimal accuracy with turning, hard-turning and grinding of bearing rings, bushings and similar workpieces, it would be ideal to accomplish the machining of all 4 sides in only one set-up. Thereby the source of error "re-clamping" would be excluded and the machine accuracy could be transferred directly to the workpiece. We can unfortunately not meet this wish; however we offer the possibility of the 3-Face machining with our electromagnetic and electro-permanent magnetic circular magnets. By clamping the parts "magnetically" at the face, this is possible. Also no radial stresses, which lead to deformations, work into the workpiece. Additionally the freed tensions can also still adjust themselves. On radial pole magnets, pole raisers, which are adjustable in T-slots, can be used in order to make the overrun of the tools possible. Usually electro-permanent systems are used, which offer high working reliability and are not heating up. The electric supply is made after the conditions of the machine by means of slip ring at the spindle end, flat slip ring in the magnet body or also by plug, which is loosened after clamping. |

Magnetic chuck diameters up to 4 meters, undivided, were already made and with multipart and/or segmental construction there is no limit in size. Our construction is characterised particularly by an even strong magnetic field, adjustable over control with demagnetising. Due to the solid pole plate, pole gap with brass, bolted in a fine grid, highest accuracy and stability is reached. The pole plate consumption is 8 mm and it can be exchanged after wear. | |

September 2008: High precision square grinding with SAV Square-Grind On the AMB exhibition in Stuttgart, SAV presents a new solution for high precision square grinding of forms and tools on standard surface grinding machines. Grinding of perfectly square parts was always a demanding task, which could only be done by experienced tool makers. SAV now offers a simple as well as elegant solution, with which this labour intensive treatment can be accomplished highly exact and even automated. The Square Grind solution consists of a stable base mounted to the machine table with highly exact, 90° Index-receptacle, preparation equipment and several 2-pole magnetic pallets for clamping of the workpieces. This configuration guarantees a fast armament, indexation in 90° steps and accuracy within 1.5 µ/150 mm on a standard surface grinding machine. The workpieces are clamped fast and secure on a 2-polige hexagonal magnet pallet on pole raisers. Hereby it is guaranteed that the accuracy is transferred in the same setting in the next machining process. |

June 2008: SAV hexagonal milling magnet - not only two corners more! With the development of the hexagonal magnets the magnet builders from Nuremberg have come-up with something completely new. The SAV thereby relies on its more than 25-year long experience with magnet solutions. The hexagonal magnet is an electro-permanent magnet system developed particularly for universal milling applications. By its durable structure, as well as by the low overall height, the milling magnet is suitable for use as single module on pallet changing systems. But also the use of multiple connected pole fields for larger surfaces is possible. The special optimized high-energy magnetic system bridges larger air gaps and thereby provides absolute safe use in chip removal applications. An assortment of pole raisers as well as individually made stop and positioning systems are available as accessories and complete the versatile ranges of application. The hexagonal magnetic poles, sealed at the surface with wear-resistant brass, make extreme holding forces possible at low magnetic field height. This again gives an advantage chip contamination problems. Together with a standard SAV control unit, SAV offers a universal milling clamping solution. |
