CNC Gun Drilling Machine
Note
- Introduced 2 spindle design.
- Single rotary and feeding of drilling spindle. Frequency speed adjustment.
- By “V” positioning block and clamping plate.
- Mainly to drill concentric deep hole as well as eccentric hole on same horizontal level of shaft and plate shaped parts.
Clamping & Positioning
CNC gun drilling machine is introduced two types of clamping.
For shaft parts, clamping is by both “V” positioning block and clamping plate.
For plate parts, clamping is by clamping plate only.
Rotary Type
Single rotation of drilling spindle.
