Chemical and mechanical wearing of high speed steel and tungsten carbide tools by tropical woods
This paper presents the chemical and mechanical wearing of high speed steel and tungsten carbide tools by some tropical woods. In the first part of the experiment, weight losses of tool materials of JIS SKH51-A, JIS SKH51-H and JIS WC-12%Co after reacting with wood extracts of coconut, oil palm, teak, red meranti and pasang were studied. In the second part of experiment, the amount of wear on the clearance face of AISI M2, AISI K5 and AISI K10 tungsten carbide bits was measured when routing these woods. The tools suffered highest percentage of weight loss when soaked in both the extractive and wood powder solution of pasang. The WC-12%Co suffered smaller percentage of weight loss compared with SKH51-A and SKH51-H. The SKH51-A suffered slightly higher percentage of weight loss than SKH51-H. The bits suffered the largest clearance wear and wear rate when used for routing oil palm wood. The wear of M2 bit was twice larger than that of K5 and K10 when routing the same wood species.
