七十年代初,意、日等国广泛采用的金刚石大锯因其具有优良的技术性能引起了我国大理石行业的广泛兴趣。SG—80D型金刚石大锯就是这一时期由北京大理石厂从日本引进的。但由于几年来在使用中出现了一些问题,因而金刚石大锯的优越性以及该不该继续引进、研制、发展,就引起了人们的普遍关注。本文试图通过对SG—80D型金刚石大锯使用情况的剖析,谈一点看法,以期引起讨论。一日产SG—80D型金刚石大锯技术性能
The early 1970s, Italy, Japan and other countries widely used diamond saw because of its excellent technical performance has aroused widespread interest in China’s marble industry. SG-80D-type diamond saw is the period from Beijing marble factory imported from Japan. However, due to some problems in use during the past few years, the superiority of the diamond saw and whether it should continue to be introduced, developed and developed have aroused people’s widespread concern.
