CNC Gun Drill Machine for Cam Shaft,ZK2120*4B/500

CNC Gun Drill Machine 

Note

• 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.

Loading System

CNC gun drill machine realizes manual loading. Automatic loading system is optional. Please refer to “GSM Machine Overview” for details or consult us for your solution.
