PENGARUH KECEPATAN POTONG TERHADAP PERUBAHAN TEMPERATUR PAHAT DAN KEAUSAN PAHAT BUBUT PADA PROSES PEMBUBUTAN BAJA KARBON SEDANG

Abstract

This research aims to know the influence of the speed rotation spindle against wear and tear and
temperature change the chisel on the process medium carbon steel lathing. This research is
experimental method research by conducting medium carbon steel lathe by using chisel of High
Speed Steel (HSS) lathe. Rotation speed of 1500 rpm lathe spindle, 1050 rpm and 750 rpm with a
depth of cut of 0,5 mm and a 0,5 mm/min feed speed shall be performed every 1 times the
pulverizing prises with a slashed workpiece length of 50 mm. Every spindle rotation speed is done
3 times the lathe process. Lathe wear and chisel lathe are measured every 1 time of the lathe
experiment. The test results in this research show that the speed of rotation of the spindle lathes to
wear and temperature at 1500 rpm spindle round earned the highest wear 0,463 mm at round 750
rpm value acquired spindle lowest wear 0,150 mm, while at 1500 rpm spindle rotation obtained the
highest temperature value of 126,3oC and at 750 rpm spindle spin obtained lowest temperature
65,0oC.

Keywords: Spindle rotation, steel, HSS, wear and temperature.
