Hydraulic valve block balance weight piston sleeve has thin wall, high precision of geometry dimension and strict roughness, and its quality determines the lifetime of balance weight directly.

缸块平衡块的活塞套壁薄，几何尺寸精度要求高，粗糙度要求严格，其质量好坏直接决定平衡块的寿命。

It is certainly that high precision equipments will eliminate the balance of work piece precision during the equipment operation, but will not eliminate other work piece errors (such as fixed error).

当然，高精度的设备就会消除设备工作时的工件精度平衡，但不会消除其它工件误差(例如固定误差)。

All the tra mi ion axle and rollers are made of high-quality steel with high-precision dynamic balance, plated with rigid chrome and grinded surface.

所有传动轴、辊材质均为优质钢，高精度动平衡校正，镀硬铬、表面研磨。
