Abstract

The present invention is one kind of grinding tool with semi-fixed abrasive particle and its making process. The grinding tool consists of abrasive grain in 80-90 wt%, adhesive 1-10 wt% and additive 5-15 wt%. Its making process includes the following steps: 1. mixing abrasive grain, adhesive and additive, sieving and mixing with water; 2. molding the mixture in a mold; 3. eliminating bubbles from the molded grinding tool; and 4. stoving the grinding toll in a stove for curing and demolding to obtain the grinding tool with semi-fixed abrasive particle. The present invention has high processing precision and high processing efficiency.

Description

(1) Technical field [0001] The invention belongs to the field of precision ultra-precision machining, and in particular relates to a semi-fixed abrasive tool and a manufacturing method thereof. (2) Background technology [0002] Abrasive machining is the main means of precision ultra-precision machining. Abrasive processing can be roughly divided into two types: free abrasive processing (including grinding and polishing) and fixed abrasive processing (such as ultra-precision grinding). Fixed abrasive processing has the characteristics of high material removal efficiency, and its processing accuracy is increasingly approaching that of free abrasive processing, but requires the use of expensive high-precision, high-rigidity equipment. Moreover, the processing deterioration layer caused by forced feeding is relatively deep, which seriously affects the service performance and life of the product. Therefore, the current precision ultra-precision machining is still the mainstrea...
