Deep hole gun drill machine

Machine Operation:Gun drilling

Component Details:  Core pins for for aluminium die casting mould

Machine Specifications:

Machine structure:

1. Drilling method: The machine adopts gun drilling method; It is with single spindle structure，It is suitable for machining long and thin shaft.
2. When drilling，the tool is rotating and the workpiece is fixed, the cutting tool is infeeding.
3. Cutter tool infeed: It adopts the structure : servo motor to drive the ball screw through  elastic coupling , which the stepless speed regulation can be realized.
4. Workpiece clamping: The workpiece is manually clamped by using the three-jaw chuck on the tailstock and the spring chuck on the guide frame, and the workpiece is supported by the center frame.

Drill bar support: 2 groups, It is used to support the drill bar ; The max hole length-diameter ratio 100:1 can be realized. Linkage between drill bar support and drill box can be achieved. as shown in the figure below.
