Product Overview: 

Rocker arm shaft is a key part of automobile power steering gear, which mainly bears the repeated torsionforce when the car is steering. The rocker shaft material is 20CrMoTi, 

which is used after carburizing and quenching. Among them, the processing of rocker shaft hole is a crucial processing link. The hole characteristics are eccentric holes and the aperture

 is inconsistent. The attached drawings are representative workpieces. The traditional deep hole drilling machine can only process the same hole diameter on one side, and the second clamping 

and tooling adjustment are needed when processing different hole diameters and eccentric holes. From the processing efficiency and accuracy can not meet the needs of mass production. 

In order to achieve the bidirectional purpose of high precision and high efficiency, the deep hole drilling machine came into being.

The practical application of the progressive deep hole drilling machine has greatly improved the processing efficiency and workpiece processing accuracy. Its special machine layout structure 

simplifies the operation flow in the processing process, and the processing of different feature holes is completed at one time.

Structural performance characteristics:

◎ Horizontal bed structure, linear guide rail;

◎ Product processing using spindle forward processing, high efficiency, good precision.

◎ The drill rod spindle adopts GSM series high precision mechanical spindle, good shock resistance and long life.

◎ The gun drill shank part is spiral clamping, clamping reliable, convenient adjustment, stable precision.

◎ The gun drill damping support adopts the auxiliary rail and quick change structure, which is quick and convenient to adjust.

◎ V-shaped tool hydraulic automatic positioning clamping, simple and reliable.

◎ Rocker shaft step hole, eccentric hole processing.

◎ The machining adopts gun drill cutting, high pressure cooling and filtering system, high efficiency and high precision.
