去毛刺技术往往是加工中的一个突出问题。尤其是对于相贯小孔内外孔口去除毛刺的工具,目前尚无专门厂家生产。我厂的产品中有一轴承:如图1所示,要求φ2.4小孔内外孔口去毛刺倒角0.3×45°。过去曾经使用刮刀、锉刀之类工具手工操作,很不理想,为此我们设计了一种小孔倒角工具,此工具既可手工操作,亦可在钻床上加工,效率明显提高,质量也很稳定。 Deburring techniques are often a prominent issue in processing. Especially for the small holes inside and outside the orifice to remove burrs tools, there is no special manufacturer. I plant a bearing products: as shown in Figure 1, requiring φ2.4 holes inside and outside the hole to the burr chamfer 0.3 × 45 °. In the past, it was very unsatisfactory to use hand tools such as scrapers and files. Therefore, we designed a small hole chamfering tool which can be operated manually or on a drilling machine, the efficiency is obviously improved and the quality is also very good stable.
