In daily production on Akiyama series presses, the chain lubrication system is one of the most common issues encountered by press operators and maintenance personnel. These Japanese-built machines feature a compact structure, high cost-performance, and a special cylinder arrangement; during maintenance, attention must be paid to the intermediate gear clearance. If not addressed in time, the consequences can range from reduced registration accuracy and print quality to extended downtime in severe cases.
1. Fault Symptoms: Abnormal noise from the main drive chain, chain jumping, elongation, automatic lubrication alarms, and excessively high oil temperature.
2. Cause Analysis: Blocked lubrication oil passages, degraded oil quality, insufficient pressure from the automatic lubrication pump, improper chain tensioning, and misaligned oil-mist lubrication nozzles. Considering the compact structure, high cost-performance, special cylinder arrangement, and the need to check intermediate gear clearance during maintenance on Akiyama Japanese presses, troubleshooting should prioritize key areas and standard parameters.
3. Parts Replacement: Flush the oil passages, replace with approved lubricating oil, verify lubrication pump pressure and cycle, adjust chain tension, and correct nozzle position.
4. Wear Parts List: For the chain lubrication system, it is recommended to keep the following in stock: related bearings/bushings, Akiyama-compatible sensors and suction nozzles, seals, and standard wear rollers. Always use genuine or certified parts when replacing, and verify model numbers.
5. Preventive Measures: Change oil at scheduled intervals, monitor oil temperature and pressure, and perform regular tension inspections. The above methods also apply to models such as Bestech 428, Bestech 629, and Jprint. For actual operations, refer to the AKIYAMA control console / automatic plate-changing system and on-site conditions. For complex situations, it is recommended to contact professional maintenance support through the printm.cn platform.
