Abstract: This study uses a quantitative methodology to test which is better than the roughness value and hardness value of both cryogenic cooling and dromus coolant methods for the manufacture of chuck locks on lathes with AISI 1045 steel material. As well as using the ANOVA analysis method to process the results. And from the results of the measurement using the Surface Roughness Tester roughness test tool carried out, it can be concluded that the chuck lock made on a lathe using the cryogenic cooling method is less roughness value, namely at the N7 level while the dromus coolant method at the N9 level according to the ISO or DIN 4763:1981 roughness standard, This means that chuck locks that go through the cryogenic cooling process can produce a smoother surface than the surface that uses the Dromus Coolant cooling method. And from the results of the Vickers test, it was concluded that cooling by the cryogenic method can increase the hardness of the chuck lock with AISI 1045 steel material, which is as much as, (10.62%) dromus coolant and (14.64%) for cryogenic acid.
