The ETK2806B CNC piston irregular hole boring machine was identified as the first major technological equipment in Hunan Province in 2018.
Our Changsha Yipai CNC Co., Ltd. designed, developed, and produced the ETK2806B CNC piston irregular pin hole boring machine, which was recognized as the 2018 Hunan Province's first major technological equipment through the review organized by the Hunan Provincial Department of Industry and Information Technology.
Currently, domestically, pin hole precision boring machines that can meet the requirements of fully automated piston production lines are very rare. The ETK2806B CNC piston irregular pin hole boring machine uses a modified overall machine structure and control technology, applying micro-displacement servo boring technology (Yipai CNC patented technology), and uses a dual-spindle, dual-station method to process pistons, completing the precision machining of piston irregular pin hole surfaces (tapered holes, curved holes). The two stations can process simultaneously or individually with free programming, not only ensuring processing precision and stability but also greatly improving processing efficiency, breaking through the requirement that both dual stations on the same machine can meet the high-quality piston precision machining requirements. The open automation interface can easily communicate with various types of robots and mechanical arms, with good compatibility. This is reflected in the bed structure design meeting the dual-station robotic arm expansion requirements, sufficient rigidity and anti-vibration performance, and the two stations processing without interference, maintaining their respective processing precision and stability. The production cycle and work efficiency meet the requirements of automated piston line assembly, especially suitable for various small and medium-sized gasoline and diesel engine piston processing automated line assembly requirements.
The improvement of piston quality is directly related to engine performance, especially with the full implementation of Euro IV and National V standards, the technical requirements for engines are becoming increasingly higher, particularly with the application of twin-turbocharging technology. Piston stress curve pin hole processing has become a new concept in pin hole processing. The ETK2806B CNC piston irregular pin hole boring machine has achieved the successful application of micro-displacement servo technology in simultaneous precision processing of dual stations, focusing on the precision processing of irregular piston pin holes to meet the requirements of automated line cycles. The technology is at the international advanced level, improving piston quality and production efficiency. Currently, this product has been sold to large piston processing plants at home and abroad, and the market prospects are excellent.
