目前,显像管制造厂家在对显像管玻屏的研磨、抛光工序中,主要采用进口的Z轮作为抛光轮,其材料成份及制造工艺较复杂,成本较高。我们利用成本较低的原材料,通过简单的制造工艺,获得研磨寿命和抛光效果不低于现有产品的显像管玻屏的抛光轮。 At present, the CRT manufacturers in the CRT screen grinding, polishing process, the main import Z wheel as a polishing wheel, the material composition and manufacturing process is more complex and costly. We use low-cost raw materials, through a simple manufacturing process, to obtain a polishing wheel with a polishing life of no less than that of an existing product’s picture tube panel.
