The main shaft , processed by numerical - control lathe , with high precision , also ensure the precision of the main shaft 平衡轴，采用数控机床加工，精度高。从而保证了平衡轴的自身平衡精度。
This model consists of three parts : frame , main shaft box and material holding shelf . supported by long axle , the main shaft box is an integral 本机型由机架，主轴箱体，载料架三部分构成，其主轴箱为
Accurate main shaft structure for heavy cutting , the main shaft is installed on a integrated main shaft head , with excellent rigidity for heavy cutting 重切削精密主轴结构。主轴安装在一体成型主轴头，重切削刚性佳。
This orientation allows the fuel tank to be closer to the main shaft reference line ? providing a consistently balanced helicopter throughout the entire flight 这个方向是让油箱靠近主轴参考线始终提供整个直升机飞行平衡
The temperature of the main shaft bearing in operation does not exceed 75 c , and the motor temperature cannot exceed the specified temperature of the motor 运转的主轴轴承温度不超过75 ，电机的温度不能超过电机的规定值。
