ZSK2103H × 4 CNC Deep Hole Drilling Machine

For reference only, the actual product shall prevail

1. Machine Tool Overview

1.1 Processing scope

Drilling range: Φ4 ~ Φ30mm

Maximum drilling depth: 500 mm

Maximum borehole aspect ratio 100: 1

Workpiece outer diameter range: Φ15 ~ Φ70mm

4 spindle structure, can have 4 workpieces at the same time, suitable for processing coaxial holes on shaft parts;

1.2 Gun drilling: internal oil supply and external chip removal.

1.3 During machining, the tool and workpiece rotate relatively, and the tool is fed.

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-808D

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; 4 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 Headstock

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.

4 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

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

1.10 Drill pipe support

1 set, the drill pipe support and the drill pipe box can be linked; The drill pipe holder can automatically adjust the spacing with the movement of the drill pipe box.

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

1.13 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.

1.14 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.

1.15 Install an oil receiving pan on the oil return groove around the bed.

1.17 Automatic loading and unloading device

A plurality of workpieces are placed on the feeding carriage and arranged in a row; The feed carriage moves to the processing area; Automatic processing of workpieces; After the processing is completed, the feeding bracket sends the workpiece to the outside of the machine tool; Remove the processed workpiece and replace it with a new workpiece to continue processing. The whole feeding action is controlled by numerical control system.

3. Main configuration list of machine tools

4. Machine tool option

Auxiliary tools, cutting tools, cutting oil.

5. Processing situation

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

Drilling roughness: Ra1.6 ~ 6.3 um

Drilling hole accuracy: IT7 ~ IT10

7. Acceptance of machine tools

7.1 The user comes to the machine tool manufacturer for pre-acceptance. 4 workpieces shall be processed. The test pieces and tools shall be provided by the user and accepted according to the contents of item 5.

7.2 The final acceptance shall be carried out at the user's factory. Carry out workpiece cutting and machine 4 workpieces. The test piece and cutting tool are provided by the user and accepted according to item 5. After passing the qualification, both parties sign the final acceptance minutes, and the signature will take effect.

8. After-sales service

8.1 Installation and commissioning

After the machine tool arrives at the user's factory, the machine tool manufacturer sends personnel to guide the equipment installation and be responsible for debugging.

8.2 Training

The machine tool manufacturer will train the user's programming, operation and maintenance personnel for 3 working days. During the training period, the machine tool manufacturer will be responsible for guiding the user's relevant technical and operating personnel to conduct trial production of typical parts.

8.3 Machine tool manufacturers strictly abide by our company's product after-sales service commitments.

9. Uncovered matters shall be negotiated by both parties.
