General requirements of sintered ndfeb permanent magnet surface smooth and reach a certain precision, blank delivery of the surface of the magnet surface flat grinding processing is required.
Square of nd-fe-b alloy polishing processing methods are: inside two end face grinding, flat grinding, grinding, cylindrical grinding, etc.
Often USES a cylindrical magnet coreless grinding, flat grinding and double side.
Tile type magnet multi-station grinding machine, fan, heterosexual magnet is used.
See a magnet product is unqualified, not only need standard, the performance of the magnet size tolerance to control also directly affect the performance and application of its products.
And a magnet size tolerance value of accurate guarantee also directly depends on the product processing power plant.
Processing equipment with the economic and social needs of the market constantly updated, more efficient equipment and industrial process automation trend, not only to satisfy the customer's need for magnets precision is growing at the same time saves the manpower and cost.
Is product and market competitiveness.
Magnet mechanical processing division: & ensp;
Punching processing, punching processing will round bar, square bar magnet into cylinder or square tubular magnet & ensp;
Cutting processing: to pass through the slicer cutting cylindrical, square magnet processed into wafer or square & ensp;
Shape processing: to turn round, square shape magnet type tile, fan, hollow or abnormity and other complex shapes of magnets & ensp;
Its shape slice processing methods are: & ensp;
Grinding slice processing, the laser biopsy processing, electric spark machining & ensp;
The ndfeb permanent magnet in the actual application of shape and performance is a wide variety of cases, such as: wafer, cylindrical, rings, cylinder (
There are inner hole)
Square piece, square;
Fan, tile type, trapezoid, hollow, much Angle of a polygon, and irregular shape abnormity, etc.
Each piece of different shapes of the permanent magnet size, performance, tolerance values, has a different magnetization.
Magnets in the production process of hard to do a molding, general production process are large output (Mr
The blank, after sintering and smelting processing through mechanical processing 【
Including cutting, punching, chamfering 】
Peace grinding, the surface coating treatment, and then to the magnetization treatment.
The best product for dimensional accuracy, surface quality, and smoke test detection such as packaged goods.
