YT2500 is a vertical CNC soaling ring machining machine produced by Yuantuo Company. It tums a sealingring with a maximum outer diameter of 2600mm. Its characteristic is the overall vertical bed, which can ensure the accuracy of the machine tool. The advanced CNC system and NGU integrated circuit system reduce the failure rate and can quickly elimi nate faults. Based on years of experience accumulated by our compamy, we have independently developed adwanced CNC program software for saling ring design and turning, thereby improving the production ffciency and quality of saling rings.
