Improper maintenance and repair of machines can cause decreased productivity and machine effectiveness. The Musical Instrument Industry is a manufacturing industry that is engaged in manufacturing musical instruments such as the piano. In the production process, many wood machines are used, such as the NC Bore Machine. Machines that operate continuously are required to meet the targets that have been set with a high level of effectiveness. The problems in the production process are that there are a lot of breakdowns that occur in NC Bore machines and a less than an optimal amount of production which results in a lack of the total machine effectiveness index (OEE). To increase productivity, Total Productive Maintenance (TPM) is implemented by analysis Overall Equipment Effectiveness (OEE). This research aims to increase the productivity of NC Bore machines. This research resulted in an OEE score of 91%, 94% machine availability, 98% performance rate, and 99% quality rate. This value meets world-class standards.
