1982年,日本光洋公司研制了装有超硬磨料砂轮的KVD-300标准型双头平面磨床,接着又在无心磨床和CNC多功能磨床采用了超硬磨料砂轮。为了适应磨削陶瓷等新材料以及高效率地磨削钢材而研制了CBN砂轮,这种砂轮的特点是成形寿命长,同一砂轮能磨削各种材料,容易实现8～12小时无人作业;砂轮磨屑少、能进行光磨;可使用小直径砂轮,便 In 1982, Koyo Japan developed a KVD-300 standard double-head surface grinder equipped with a superabrasive grinding wheel followed by a superabrasive grinding wheel in a centerless grinder and CNC multi-purpose grinding machine. In order to adapt to grinding of new materials such as ceramics and high efficiency grinding of steel developed CBN wheel, this wheel is characterized by long forming life, the same wheel can grind a variety of materials, easy to achieve 8 to 12 hours of unmanned operations; Abrasive grinding wheel less, can be light grinding; can use a small diameter wheel, then
