目前,由热压绝电陶瓷材料和轻耐火材料(带添加剂氮化硼、氧化钇和氧化锆的二氧化硅基的)制的薄壁(厚度为2～5mm)精密零件(有急剧的过渡截面),其制造甚为困难。因被采用的刀具,使用特性低。 本文介绍加工上述零件用的专用薄刃车刀(见图)的制造试验结果。切削部分由氧化铝基高强度真空密实耐热陶瓷 BK-94-1(22XC)制造(陶瓷的密度为3.73～3.76g/cm~3,硬度为HRA91～93)。其用真空钎焊法与钢质刀杆连接。
At present, thin-walled (thickness of 2 to 5 mm) precision parts made of autoclave ceramic materials and light refractory materials (silica based additive with additive of boron nitride, yttrium oxide and zirconium oxide) Section), it is very difficult to manufacture. Due to the tools used, low-use characteristics. This article describes the manufacture of these parts with a special thin blade turning tool (see photo) manufacturing test results. The cutting part is made of alumina-based high-strength vacuum dense heat-resistant ceramic BK-94-1 (22XC) with a ceramic density of 3.73-3.76 g / cm 3 and a hardness of HRA 91-93. It is connected to the steel arbor by vacuum brazing.
