How are NdFeB magnets produced? What machines are needed to produce NdFeB magnets? What processing equipment? How long does it take to produce a batch of NdFeB?

1. How are NdFeB magnets produced?

    The production of neodymium iron boron magnets mainly depends on the slicing process of the slicing machine. NdFeB magnet blank materials are bought back, and then processed and produced according to the size of each customer's needs. However, the production and processing equipment of NdFeB magnets is relatively simple and single. When the cutting machine for producing and processing NdFeB magnets is working It can only be cut slowly with one knife, and when one size is cut, the material must be re-adhesive and re-cut, which seriously impairs the production efficiency of NdFeB magnets. After years of exploration, the NdFeB magnet production slicing machine has been improved many times, and the multi-wire cutting slicing machine has been successfully developed. Both the punching production efficiency and the processing technology have been greatly improved. Every time a size is cut before It is necessary to re-adhesive materials and re-typesetting and cutting, and multi-line cutting avoids this problem.

2. What is the difference between the multi-line slicer and the ordinary slicer?

    Two sample vertical stop positions (up and down) Five slicing modes: single, continuous, step, half cut, programming. The slicing speed is automatically adjusted according to the slice thickness, and the trimming function can be turned off. In the automatic state, the parameters of the repair block are automatically adjusted, and in the manual state, the parameters of the repair block can be programmed and determined. The slice thickness and trimming thickness can be independently selected and stored. The visual signal and the sound signal indicate the limit of advance and retreat and the remaining injection distance during sample injection. The slicer is a machine for cutting thin and uniform tissue slices. The tissue is supported by hard cast iron or pig iron. It automatically uses a slice thickness gauge for each cut. Advance (toward the direction of the knife) the required distance to control the dimensional accuracy of the neodymium iron boron powerful magnet. The thickness of the thickness gauge is usually 1 micron. When cutting the paraffin-embedded tissue, because it adheres to the wax edge of the previous slice, multiple slices are made.

3. Manufacturing process: NdFeB is manufactured using powder metallurgy technology

   Process flow: Ingredients → smelting ingot → powder making → compaction → sintering and tempering → magnetic inspection → grinding process → pin cutting process → electroplating → finished product.

   The process from cutting the finished product to becoming an electroplated finished product: picking-sticking-cutting-black chip inspection-cooking-receiving-polishing-electroplating-white chip inspection-finished product.

4. How long does it take to produce NdFeB?

   Normal disc magnets need 7-10 days, discs need 12-15 days to punch holes, and square ones require 3 cuts to form, which is also 10-12 days.
