Dimensional tolerance and Geometric Tolerance is one of the most important factor to measure quality of neodymium magnets, the manufacturing capacity, processing capacity and quality control.
Dimensions and tolerances shall be as specified on the neodymium magnet drawing and must be agreed upon between the neodymium magnet manufacturer and user before an order is accepted. Normally the neodymium magnet user furnishes a drawing to us showing all dimensions and tolerances. When no drawing is available from the user, our technical department may furnish a drawing to clients for his approval before manufacturing parts. The standard for drawing, drawing notation and tolerancing is that established in ANSI Y 14.5.
Please see our normal tolerance for different sizes and shapes:
GME are able to manufacture according to customer's sample or drawing/blue print.
