DDB II Series - Deep Drill Boring Lathe
- Total layout of DDBII type deep hole drilling boring lathe is headstock movable mode.
- It is main used for machining workpiece of cast iron, cast steel, forged steel etc. material, which is performed drilling hole, counter-boring, fine boring, etc. deep hole machining.
- High low layout for bed of workpiece and bed of drilling
- The headstock is mounted on the sliding plate of headstock, and can move or be clamped on workpiece bed according to workpiece length.
- Rotating (drilling) or fixed (for boring) tools can be equipped for drilling rod box.
- The drilling rod box is installed on the drilling rod feed sliding plate. The drilling rod movement have three transmission modes, can selected by according to conditions. The first is driven by reducer and screw lead via D.C motor. The second is transmission of gear-rack. The third is transmission of double gears-rack.
- The machine is equipped with 828D CNC system and feedback device for Z axis.
- The turning face's tool post is equipped with turning workpiece face's machine.
- The machine can be equipped with horning function with feed device and cooling system.
