A new magnetostriction material boring bar is presented for precision finishing of different types of odd-shaped pinholes, and structural optimization and test validation are carried out.
Finally through the test of finishing products, it is proven that the round bar produced by slitting technology can completely meet the requirement of the quality.
最后通过成品检验证明，采用圆钢切分轧制技术生产的建筑用圆钢完全能满足产品质量要求。
