日本一家公司最近研制出一种磁力研磨机。该研磨机靠磁力使加工件在机器内呈悬浮态,然后靠研磨剂自身的旋转进行研磨作业,无损坏或擦伤之虑。一次可进行150～200件的大批量研磨,18K金只在30分钟,Pt金需45分钟便可磨好。该研磨机的最大优点是,可处理手工操作无法触及的微区,且不使用苛性药剂,作业环境清洁。 A Japanese company recently developed a magnetic grinding machine. The grinding machine by magnetic force to make the workpiece was suspended in the machine, and then by grinding their own rotation grinding operations, no damage or abrasions considered. Once 150 to 200 large quantities of grinding, 18K gold only in 30 minutes, Pt gold need 45 minutes to grind well. The biggest advantage of the mill is that it can handle the micro-area that can not be touched by manual operation, and does not use caustic chemicals to clean the working environment.
