Due to the diversification of product varieties and the increase in production volume, improving the cycle time of existing hydraulic cylinder-based press fit equipment had become an urgent necessity. When considering electrification, we looked into general screw jacks, but it was difficult to increase the operating speed to 200 mm/s in order to meet the high load condition of using a thrust of 20 kN. If we prioritized thrust, the speed would be insufficient, and if we prioritized speed, the thrust would be insufficient, making it difficult to select an electric actuator that met the required specifications.

By adopting Linispeed Jack, we were able to achieve a high thrust of 20kN while enabling high-speed operation of 200mm/s from homing to the start of machining. This significantly reduced idle time other than pressurization, and we succeeded in shortening the target cycle time. In addition, the change from hydraulic to servo motor drive has made it easier to set detailed conditions for each product type, improving operational flexibility.
