And obtain the magnetic material blank with certain magnetic property.The processing of sintered NdFeB is exactly to add this blank by various mills
Work cuts the process that finished product is made after the techniques such as processing and surface treatment.It is traditional cut processing using inner circle slice cut plus
Work can make workpiece cutting face obtain certain roughness, flatness etc., as Nd-Fe-B permanent magnetic product is more and more very popular,
Under the situation of high-volume consecutive production pattern, the introducing for cutting process equipment of multi-line cutting machine has been broken inside diameter slicer and has been added
The limitation of work so that the working ability and technical merit of sintered NdFeB step and gone up a big step again.As shown in Figure 1, giving
The processing process of sintered NdFeB in the prior art is gone out, it can be seen that after being machined by multi-wire saw, usually need
The oil sheet after processing will be cut or mortar piece carries out inserted sheet and boils material tooling, the process that inserted sheet boils material tooling just needs to use a people
Then work carries out ultrasonic cleaning and boils material cleaning, the glue of the magnetic mud and consolidation of such oil sheet or mortar on piece all can be into
Enter in cleaning solution, the service life of cleaning solution can be greatly shortened in this way and consume a large amount of cleaning solution, boils the neodymium iron after material cleaning
After boron small pieces are dried, mill processing then could be carried out, and for large-size workpiece, boil the workpiece drying after material cleaning
Surface cleanness afterwards is poor, when being ground the cutting face after multi-wire cutting processing using double-ended grinding machine, can only also be added by mill
Work improves the surface cleanness of 2 cutting faces end face, increases difficulty to the facing operation of subsequent handling in this way.Also pass through
Neodymium iron boron small pieces after overground processing also need to be dried, and thus need to be dried twice, entire technical process both consumed
When, artificial and production cost is also high, and most importantly product quality is also bad.Therefore, such as how high quality, the technique of low cost
Method realizes the mechanical processing of sintered NdFeB, is that the industry is badly in need of technical problems to be solved.
