D51 Ring Rolling Machine The advantages of D51 Ring Rolling Machine Original appearance of machine, the machine base is weld-formed by steel plate, such structure is light and sinky and has a good rigidity. Reasonable and scientific design for machine tool, the machine tool has high rolling accuracy for the new design and development of distribution of main shaft bearing. Rectangle section of upper sliding block and good rigidity. The length of guide rail of sliding block is increased to 5-6 times of journey of sliding block and guide accuracy is high. Main parts of machine are all made of cast steel or high-quality alloy steel. Sealed lower supporting bearing to make it working normally in a poor condition. Sealed with YX O-ring in accordance with International standard, low resistance of cylinder, The advantages of D51 Ring rolling machine reliable seal performance and good abrasive resistance. The rolling wheel is fixed with an internal cone-shaped expansion ring and its locating accuracy is high, the rolling wheel can be disassembled and replaced easily. The fine-grinding machine id driven in a synchronized mode and runs smoothly, a wide adjusting range is available. A muffler is equipped for exhausting system of gas pipeline to reduce noise and protect environment
