过去生产轴承环、齿轮、法兰等环形坯料的轧环机,主要依靠操作者的视觉和操作技术进行轧制,因此产品精度低,均匀性差。现在日本三菱长崎机工株式会社研制成一种用计算机控制的自动轧环机。下面作一简要介绍。 In the past, ring rolling mills that produced ring blanks, such as bearing rings, gears and flanges, relied mainly on the visual and operational techniques of the operator for rolling, resulting in low accuracy and poor uniformity. Now Japan’s Mitsubishi Nagasaki Machinery Co., Ltd. developed into a computer-controlled automatic ring rolling machine. Here’s a brief introduction.
