随着林业机械化程度的日益提高,使用CY—5,GT—85,YT—4等型号的四—五马力油锯采伐正在我区各林场日益普遍。特别是近年来,国产四—五马力油锯具有转速高,马力大,自动进锯,锯切效率高等特点,受到林业工人的欢迎。 我区工人在使用这些油锯的过程中,普遍存在的一个问题就是在锯切过程中,锯导板端部退火,从而使整个导板报废,给工作造成了损失。 With the increasing degree of mechanization of forestry, logging with four to five horsepower chainsaws such as CY-5, GT-85 and YT-4 is becoming increasingly common in various forest farms in our region. Especially in recent years, homemade four - five horsepower chain saw with high speed, horsepower, automatic sawing, sawing and other high efficiency, welcomed by forestry workers. A common problem in the use of these chain saws by workers in our district is that during the sawing process, the end of the saw guide is annealed, causing the entire guide plate to be scrapped, resulting in a loss of work.
