Permanent-electro magnetic systems The advantages of magnetic work-holding for machine tool “ Modern machine tools, sophisticated machining centers and technological tools are designed to produce a greater number of high quality parts in the shortest possible time. The safe, uniform and deformation-free clamping of the workpiece, its fast set up and free access of the tool on all faces are key aspects to enhance the performance of the entire process and speed up the return on investment “

Permanent-electro magnetic systems The main advantages of the permanent-electro magnetic system MAG AUTOBLOK TECNOMAGNETE ➢ Uniformity of work-holding over the entire contact surface ➢ Free access of the tool on the 5 machining faces ➢ Workpiece positioning and clamping speed ➢ Absence of vibrations during processing ➢ Better cutting quality and longer tool / insert life ➢ Respect of the condition of the piece without tension or deformation ➢ Flexibility in clamping pieces of any size or shape ➢ Reliability of piece clamping always the same over time ➢ Permanent, constant and predictable magnetic...

Evolution of the permanent-electro magnetic plate for milling. Electro-permanent magnetic technology for clamping work-pieces on machine tools is now of common use thanks to obvious application advantages. However, not all products available on the market are the same because over the years some fundamental evolutionary stages have determined important technological and construction differences, especially for the magnetic chucks used on machining centers and milling machines. QUADSYSTEM. Technological innovation: from the old permanent-electro magnetic plate with mono-directional parallel polarity...

Permanent-electro magnetic systems TECNOMAGNETE Tecnomagnete patents the permanent-electro double magnet technology. Technological innovation: magnetic square pole bi-directional QUADSYSTEM (Tecnomagnete patent). Current technological state of competition. Construction Innovation: MILL-TEC (Tecnomagnete patent) the frame is machined "from solid", the permanent magnets and the electric coils become an integral part of the system in a single piece. Construction evolution: QUAD-EXTRA (Tecnomagnete patent) the entire work surface consists of a single mono-block polar plate -Limited use of epoxy resin....

Permanent-electro magnetic systems Operation of the permanent-electro magnetic circuit Static phase DEMAG (surface demagnetized) The polarization of the reversible magnet Al.Ni.Co and that of the static magnet Neodymium create a “magnetic short circuit” with a flattened circulation of the flux only within the system. No electric current is used during this phase. Magnetization cycle (or Demagnetization) An electrical impulse lasting a few fractions of a second changes the polarization of the reversible magnet Al.Ni.Co therefore remaining its status indefinitely. Static phase MAG (surface magnetized)...

The magnetic clamping force of a workpiece is proportional to the contact surface and to the square of its magnetic flux density. Consequently, to ensure a better clamping force, it is recommended to cover the largest number of North and South magnetic poles and above all to improve the quality of contact with the piece as much as possible through the use of suitable pole extensions and the choice of the correct magnetic generator. Factors Affecting Density of magnetic flux Indicative values of performance reduction and application considerations Roughness of the piece Type of material ■ 100%...

Permanent-electro magnetic systems Polar extensions and automatic shimming The use of polar extensions suitable for the application reduces the operating air gaps and improves the magnetic flux density. They can be used to elevate the piece and machine the 5 faces in a single placement, for contouring, chamfering, through drilling operations or to create mechanical, magnetic stops and dedicated jigs. It is possible to carry out the automatic shimming of deformed pieces through the use of mobile extensions that avoid the tensioning of the piece during the work phase. Phase 1 Place the workpiece...
