The core contradiction between new energy and traditional automotive parts production lies in the consistency of parts in large-scale production. There are various types of motor shafts, transmission discs, and brake accessories, and long axis workpieces are prone to tool vibration and coaxiality deviation during processing; The order fluctuates greatly and often switches between large-scale production and small-scale sample production. Many processing plants have reported that after a period of mass production, the accuracy of ordinary equipment drifts, and the size of parts in the same batch fluctuates greatly, directly affecting assembly; Pursuing efficiency can easily sacrifice surface quality, making it difficult to balance production capacity and yield.
Equipment selection should focus on dynamic response, tool changing efficiency, and long-term accuracy maintenance. Harman Precision TC200 high-speed series and dual spindle single blade tower series are specially designed for automotive parts working conditions. The dual spindle model relies on the main and secondary shaft workpiece docking technology, and the secondary spindle replaces the traditional tailstock. It completes the machining of both ends of the shaft workpiece in one clamping, greatly improving the vibration problem of long shaft machining and ensuring the coaxiality index. TC200 high-speed series knife? The tool change time is less than 0.1 seconds, with fast movement speed and a 20% increase in overall processing efficiency? 40%, effectively reducing single piece work hours.
The machine tool bed is made of Mihana cast iron, which has undergone aging and stress relief treatment. The core transmission components are made of Japanese THK screw guides to suppress the accuracy degradation caused by long-term mass production. The equipment supports the selection of automatic feeding and unloading robotic arms, building simple automation units, reducing manual intervention, and adapting to large-scale production on the production line.
Many auto parts companies tend to overlook after-sales process support, and debugging new workpieces consumes a lot of manpower. Harman Precision Machinery conducts pre-sales evaluations of workpiece processes, completes installation and debugging during sales, and provides free process optimization and operation training. The nationwide localized after-sales network ensures equipment utilization rate, helping auto parts manufacturing enterprises cope with order changes calmly, balancing sample and large-scale production, and maintaining stable consistency in batch part size.
