Preventive Maintenance Program



Preventive maintenance (PM) has the following meanings:
• The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.
• Maintenance, including tests, measurements, adjustments, and parts replacement, performed specifically to prevent faults from occurring.
• The primary goal of maintenance is to avoid or mitigate the consequences of failure of equipment. This may be by preventing the failure before it actually occurs which Planned Maintenance and Condition Based Maintenance help to achieve. It is designed to preserve and restore equipment reliability by replacing worn components before they actually fail. Preventive maintenance activities include partial or complete overhauls at specified periods, oil changes, lubrication and so on. In addition, workers can record equipment deterioration so they know to replace or repair worn parts before they cause system failure.
• The ideal preventive maintenance program would prevent all equipment failure before it occurs. Sinutech Machine tool maintenance program is complete machine condition-monitoring program. This is done with the use of pro-active and preventive maintenance, forming a baseline or footprint of the machine. See examples below. By doing this, studies have shown large savings in maintenance costs and increased productivity due to less down time.
