机用锯条是机器制造业中切割金属不可缺少的工具,它的消耗量很大,而且价格也比较高,所以如何翻新废锯条,是一个值得研究的问题。过去我厂是采用把废锯条退火后重新磨出锯齿的方法翻新。用这种方法在热处理方面,技术要求比较高,往往由于处理的不当,翻新后锯条寿命会比原来低。同时,这种翻新方法还要经过退火、铣齿(或刨齿)等许多工序,如果翻新的锯条数量较少,则翻新后锯条的成本会比新锯条还要高,因此很不合算。
Machine saw blade is an indispensable tool for cutting metal in the machine manufacturing industry. It consumes a lot and is relatively expensive. Therefore, how to renovate the used saw blade is a problem worth studying. In the past, our factory adopted the method of re-grinding sawn teeth after annealing the used saw blade. In this method in the heat treatment, the technical requirements are relatively high, often due to improper handling, saw blade life after renovation will be lower than the original. At the same time, this method of refurbishment is subject to many processes such as annealing, milling (or planing) and, if the number of reconstructed saw blades is small, the cost of the saw blade after retrofitting will be higher than that of the new saw blade, making it uneconomical.
