Abstract

The most important characteristic factor of cutting tools is cutting ability. One of the factors that influence cutting ability of cutting tools is wear resistance. At market there are many large selection of HSS tool steel with different type and merk. One of them was HSS tool steel made in Austria and Taiwan which share the same trade mark but have significant differences at price. The research aimed to compare HSS cutting tools quality made in Austria and Taiwan consider from wear, tool life and material structure aspect. This research had done by flank wear experiment to the HSS cutting tools. The specimens were BOHLER RAPID EXTRA 1200 with 3/8 x 4” on size made in Austria and Taiwan. The work piece specimen used ST60 steel. Flank wear experiment of cutting tools had done by turning cutting tools to the work piece with four cutting speed variation like 19,99 m/min, 25,72 m/min, 26,53 m/min and 30,65 m/min that had given, then measured flank wear dimension (VB) using microscope that completed with dial indicator and pixel method. The result of this research showed that Austria HSS tool life which had the longest time at low cutting speed (Vc=19,99 m/min) was 100 minute (dial indicator) / 92,5 minute (pixel), and tool life which had the shortest time at high cutting speed (Vc=30,65 m/min) was 25 minute (dial indicator) / 26,5 minute (pixel). Taiwan HSS tool life which had the longest time at low cutting speed (Vc=19,99 m/min) was 87,5 minute (dial indicator) / 84,5 minute (pixel), and tool life which had the shortest time at high cutting speed (Vc=30,65 m/min) was 25 minute (dial indicator) / 22,5 minute (pixel). The conclusion of this research is that HSS cutting tool made in Austria with more expensive cost, but has higher wear resistance and longer tool life than HSS cutting tool made in Taiwan.
