Double Spindle CNC Gundrilling Machine For Military And Defense

1. Machine tool overview

1.1 Processing range

Drilling range: Φ5 ~ Φ20mm

Maximum drilling depth: 500 mm

Maximum workpiece range: Φ15 ~ Φ85mm

1.2 Gun drilling method, double spindle structure, can use two workpieces at the same time, suitable for processing coaxial holes on shaft parts; At the same time, it has the function of pulling hinge. After drilling is completed, replace the reamer and auxiliary damping device, and the clamping mode is consistent with drilling. It is convenient and quick to change the cutter, and the reaming and gun drilling feed are opposite.

1.3 During machining, the tool and workpiece rotate relatively, and the tool is fed. Used for machining coaxial holes on shaft workpieces.

1.4 Workpiece clamping

The front end of the spindle of the head box and the guide frame is equipped with a conical disk, and the hydraulic system controls the axial movement of the spindle of the head box, and automatically clamps and positions the workpiece by using the chamfering of the conical disk and both ends of the workpiece; The center frame is supported in the middle part of the workpiece.

1.5 The guide rail used on the machine tool adopts linear guide rail.

1.6 CNC system: SIEMENS

1.7 Drill pipe box

The servo main motor is used to drive the spindle to rotate through the synchronous belt and synchronous pulley, which can realize stepless speed regulation, and the maximum speed of the spindle is 5000r/min; Double spindle structure, one motor drives two spindles to rotate; The spindle is driven in front, which is beneficial to protect the main motor and facilitate tool change.

1.8 bedside box

Drive the workpiece to rotate at a constant speed of 117r/min; The spindle can be axially moved under the control of the hydraulic system and is used to tighten or loosen the workpiece. The spindle is driven in front, which is convenient for loading and unloading

workpieces and helps to protect the main motor.

Double spindle structure, one motor drives two spindles to rotate.

It can be manually moved on the linear guide rail of the workbench, and after moving into position, it is manually locked on the workbench by locking block.

1.9 Tool feed system

With the structure of ball screw driven by servo motor, the cutter feed can realize stepless speed regulation.

1.10 Drill pipe support

1 set, supporting drill pipe.

1.11 Cooling System

It is mainly composed of high-pressure pump unit, chain plate chip removal machine, oil cooler, filter device, etc. On the numerical

control system operation station, assemble the cooling system flow adjustment panel.

1.12 Basic parts such as bed and box are cast with resin sand and have undergone twice aging treatment. The oil return tank of the bed body is inclined and will not store oil.

1.13 Guide frame

Used for tool guidance, chip removal, supporting tool bars. The front end thereof is equipped with a guide sleeve for tool guidance;

The rear end is equipped with a cutter bar support sleeve for supporting the cutter bar.

1.14 The machine tool is equipped with full protection.

5. Machine tool option

Other CNC systems, auxiliary devices, cutting tools, cutting oil, automatic oil throwing machines, etc.

6. Processing situation

Center deviation of inlet and outlet of drilling hole: 0.5 mm/1000mm (workpiece rotation)

Drilling roughness: Ra1.6 ~ 6.3 um

Drilling hole accuracy: IT7 ~ IT10
