Abstract

The purpose of this research is to determine the hardness of guide hole. A guide pin and a guide hole of SSD(Solid State Drive) tester used to mount SSD in a fixed position accurately. The guide pin and guide hole are worn by friction due to repeated operation, and the wear is concentrated on the guide hole made of weak material rather than the guide pin made of relatively strong material. Because of that reason, it is often overdesigned in the design stage because it can lose its function. If the guide hole is made soft, the manufacturing cost will decrease, but the accuracy will decrease due to wear caused by repeated friction. If the guide hole is manufactured excessively, the manufacturing process becomes complicated and the manufacturing cost increases. It is essential to design a guide hole, but since there is no standard or verified data that can be referenced, it is difficult to design. Experimental device which guides in the same way as the SSD tester is used for this research, and three types of anodizing state are experimented for different hardness. Also, weight of COK(Change over Kit) were analyzed by measuring the wear amount and state of the guide hole according to the number of repeated attachment and detachment.
