Abstract

Taji is a type of special knife made for certain purposes, which in Balinese means sharp. The material for these spurs in the Bali area is made from used temple stone cutter knives. The material for this temple stone cutter knife is made from HSS (high-speed steel). The process of making spurs starts with cutting the main material using a water-cutting process. The main process, namely grinding, aims to shape the material according to the required shape, especially the pointy and sharp parts. The rotation or RPM of the bench grinder and hand grinder is 1400. This very high rotation will of course cause friction which results in heat in the main material even though cooling is used. This change in structure will result in changes in the mechanical properties of the material. Reducing heat can be done by reducing the friction that occurs. Reducing friction is done by varying the rotation of the grinding machine. This grinding machine is equipped with variable rotation which can be adjusted according to needs. This research will be carried out by varying the grinding rotation during the grinding process, namely 100 RPM, 200 RPM, and 300 RPM. The temperature is measured on the main material before and after the grinding process treatment. The grinding results are subjected to a photo microscope process to see the microstructure of the material. The grinding process with this rotation only provides a maximum increase of 11.12% from the initial temperature of 27.47℃ to 30.90℃. The grinding machine can be used for the process of making spurs by craftsmen because it does not affect microstructure changes that can affect the mechanical properties of HSS steel.
