CNC Gun Drill Machine
- Introduced 4 spindle design, 2 spindle design is also available.
- Introduced counter-rotary method. That is, workpiece and drilling spindle rotate simultaneously but at different direction.
- Version of drilling spindle single rotation is also available (Model: ZK2120*4/500).
- Contralateral feeding of drilling spindle can be satisfied in term of drilling requirement.
- Fits for drilling of shaft parts. Typical parts like high pressure common rail pipe, cam shaft and gear shaft, etc.
Clamping & Positioning
Clamping and positioning is by chamfer or center hole.
(ZK2120*4/500 is by special tooling)
Counter-rotary of drilling spindle and workpiece.
(Drilling spindle rotates only for Zk2120*4/500)
