Description

TECHNICAL FIELD

[0002] Generally, in order to reduce stress, aesthetics or assembly requirements, etc., many types of components with fixed shapes have chamfers. For example, before electroplating of neodymium iron boron products, different degrees of chamfering are required. At present, the chamfering process of neodymium iron boron products with inner holes mainly relies on a vibrating chamfering machine: the abrasive stone is mixed with the product, and vibration makes it move, and the abrasive stone is controlled to rub with the product, so as to make the corners smooth. This chamfering method makes the inner hole chamfering small and the outer corner chamfering large, and the control is relatively vague, and the chamfering effect is consistent in statistics, but in fact, the chamfering size distribution is not concentrated, and the individual difference is large, and the chamfering effect of the inner hole is very poor, and it is only suitable for occasions with low chamfering requirements.

Therefore, it is inevitable to chamfer the single product. At present, the chamfering of the inner hole is mainly completed by hand: taking material, positioning, fixing the product, controlling the feed, grinding and retracting of the grinding head or tool, and processing the other side, and this chamfering method has good effect, but the efficiency is low and the labor cost is high.
