机器特性：

•  主要采用高级铬钼合金钢，经调制及渗碳热处理，表面栓槽及螺纹都经精密研磨加工而成
  
• 排齿管表面经热处理及镀硬件铬，耐磨耗，不易变形
  
• 变带箱齿轮也均采用高级铬钼合金钢，确保传动低噪音，经久耐用
  

Machine characteristics:

• Mainly made of high-grade chromium molybdenum alloy steel, which has been modulated and carburizing heat treated. The surface grooves and threads are precision ground and processed
  
• The surface of the toothed tube is heat-treated and plated with hardware chromium, which is wear-resistant and not easily deformed
  
• The gearbox gears are also made of high-grade chromium molybdenum alloy steel, ensuring low transmission noise and durability
