Bushing:
Accurately locate the gun drill and guide the drill into the workpiece. And play the role of sealing cutting oil during processing. The material is divided into 9SiCr and cemented carbide. The guide bush is the most sensitive and precise accessory that affects the machining accuracy.
Oil guide:
The oil retaining ring is sleeved on the gun drill and installed in the chip box, between the adjusting plate and the shock-absorbing sleeve. Block the oil and chips generated by cutting and prevent oil and chips from entering the rear end of the bearing.
Support package:
The support sleeve is installed on the drill rod support frame, and its inner hole varies with the size of the drill bit. Used to support and stabilize the gun drill. When the hanging length of the gun drill exceeds 35 times the diameter of the drill bit, a support sleeve must be used. It is an important condition for stable processing of gun drills.
Workpiece front and rear top plates
roof:
The inner cone surface of the top plate cooperates with the outer chamfer of the workpiece to precisely position and clamp the shaft parts.
