最近,日本研制出一种用超硬磨料制作的精密磨削工具——电铸砂轮刀片,这种电铸砂轮能对硬脆材料进行精密切槽加工及高速、高效磨削加工。电铸砂轮是采用一种分散电镀方式制成的,即将磨粒悬浮在电镀槽中进行电镀,由电镀金属将磨料固结在基体金属上,形成磨粒均匀、强度极高的砂轮。电镀金属一般选用电镀镍,因为它的机械强度高,且易于进行复合电镀。其粒度选择可根据加工面精度及磨粒锐利度来确定,一般在4000~#至400~#范围。砂轮厚度通常在400μm以下,最薄的甚至只有15μm,因此,最适宜制成超薄型刀片。而象金属结合剂砂轮之类用粉末法制造的砂轮,厚度变薄后,其厚度精 Recently, Japan has developed a precision grinding tool made of super-hard abrasive - electroformed grinding wheel blade, this kind of electroforming grinding wheel can be hard and brittle material for precision grooving and high-speed, high-efficiency grinding. Electroforming grinding wheel is made by a decentralized electroplating method, that is, the abrasive grains are suspended in a plating bath for electroplating, and the abrasive is consolidated on the base metal by the electroplating metal to form a grinding wheel with uniform abrasive grains and extremely high strength. Plating metal plating nickel is generally used, because of its high mechanical strength, and easy composite plating. The choice of particle size can be based on the accuracy of the processing surface and abrasive sharpness to determine, generally in 4000 ~ # to 400 ~ # range. Wheel thickness is usually below 400μm, the thinnest or even only 15μm, therefore, the most suitable for the manufacture of ultra-thin blade. And like the metal bonded grinding wheels and the like powder wheel made of powder, thinner, the thickness of fine
