REKONDISI DAN PEMBUATAN SOP PERAWATAN MESIN FRAIS LAGUN SERI 17

Abstract

Polman Babel's mechanical workshop has various types of machine tools, one of which is the Lagun 17 series milling machine which is a type of universal milling machine. This machine is used as a student practicum learning facility and is also used for production purposes. The lack of maintenance on the engine leads to damage in some parts of the machine. After going through the stages of analysis, planning and repair of the machine, a testing stage is carried out which includes testing functions, geometry, road tests with workpiece loads and vibration testing. The results of some of these tests are still in the standard values, the geometry test results have a deviation of 0.195 mm in the alignment of the surface of the transverse motion table along 100 mm. The vibration test results on the axis of the variable speed shaft are still within ISO 18016 tolerance. In addition to making repair actions, machine maintenance SOP are made consisting of inspection, small repair and medium repair with the aim of machine maintenance being paid more attention to and carried out in accordance with the existing maintenance schedule.
