Evaluating the Properties of Diamond Drillers Made from Composite Electroplating

This project is cooperative with Besdia company to improve the properties of diamond drillers manufactured through co-electrodeposition of artificial diamonds and Ni deposit. Besdia company, which is a typical traditional manufacture factory in Taiwan, has been experienced to fabricate abrasive and grinding tools by using artificial diamond and ceramics for over 30 years. The company’s products are sold and used all over the world. To improve company’s competition ability, manufacturing processes for diamond abrasive tools have been investigated. Diamond drillers are needed presently in industrial applications; moreover, the quality of the diamond driller could be an obvious milestone for the related cooperative company. In this project, manufacturing and evaluating diamond drillers are the main purposes. Medium steel in a bar form is used as the substrate for the co-electrodepoition of artificial diamond and Ni deposit. To make a diamond driller, the medium steel bar was pretreated, put into the Watt’s Ni bath with different concentrations of 50-μm-diamond particles. After composite-electroplating, the coated medium steel bar will be drilled and etched at the end to produce a diamond driller. Diamond drillers with diameters of 6 and 10 mm will be manufactured in this project. To evaluate the property of a diamond driller, the drilling force will be measured during drilling aAl2O3 plate with a thickness of 8 mm under constant cutting feed and the surface morphology of drilled Al2O3 plate will be examined.We plan to prepare at least 20 diamond drillers made with different electroplating parameters for various tests. An optimal process will be proposed to produce a diamond driller via co-electrodeposition of artificial diamond and Ni. The process could be expectedly finished within 10 hours. We expect the proposed process could be used in industrial application.
