About CNC gundrilling machine

1. Machine brief:
1.1 Processing Capacity :
Drill diameter range: 4~30mm

Max. Drill depth: 1000mm
Max. Drill depth and hole diameter ratio : 100:1
Workpiece OD range: 15~150mm

1.2 Processing Mode

Adopt gun drilling method , single spindle structure, suitable for machining coaxial hole on shaft parts; When drilling, both workpiece and cutting tool rotate in opposite directions, cutting tool feeding.

1.3 Workpiece clamping:

The cone discs are mounted in front end of headstock and guide frame spindle. The hydraulic system control the headstock spindle to move axially, to clamp and position the workpiece automatically with the cone disc and chamfer on both ends of the workpiece.

1.4 The machine adopts linear guide rail .

1.5 CNC system : FANUC CNC system

1.6 Drill box:

Adopt the servo main motor driving the spindle to rotate through synchronous belt and synchronous belt wheel, speed stepless could be realized , the max. rotation speed of spindle is 6000r/min., the main drive is pre-positioned ,good for protect the main motor and easy to exchange the cutting tool.

Main motor power: 5.5KW;
Max. rotation speed

1.7 Headstock:

Drive the workpiece to rotate, rotation speed is fixed 117rpm ; The spindle can move axially under the control of hydraulic system to tighten and loosen the workpiece . The main drive is pre-positioned ,good for protect the main motor and easy to load/unload the workpiece.

Power: 1.5KW;
Rotation speed: 117r/min

1.8 Cutting tool feeding system :

Adopt servo motor driving ball screw structure , the feeding rate of cutting tool can realize speed stepless.

Feeding speed range: 5-500 mm/min
Rapid move speed: 4m/min
Feeding motor torque: 7.5 Nm

1.9 Drill bar support rest :

2sets, used to support the drill bar .

1.10 Coolant system :

Mainly composed of high pressure pump groups, chain plate chips conveyor, oil chiller , filtering device and so on. On the CNC system operation station, the coolant system flow adjustment panel was assembled.

1.11 Bed body and box body

The basic parts such as the bed body and box body are cast with resin sand and undergo two aging treatments. The inclined design of the bed oil returning slot prevents oil storage.

1.12 Guide frame

Used for guiding the cutting tool , discharge cutting chips , supporting the drill bar. The guide sleeve is mounted in front of guide frame, and is used to guide the cutting tool ; and the rear end is mounted with drill bar support rest for supporting the drill bar.

1.13 Safety guard :

The machine is equipped with full safety guard.

2. Processing accuracy :

Hole entry and exit deviation

(Max. hole length-diameter ratio 100:1): 0.5mm/1000mm (workpiece rotation)

1mm/1000mm (workpiece fixed)

Hole surface roughness: Ra0.8~3.2m
Hole size accuracy: IT7~IT10
