D-G400 CNC Machine Tools
The ZD-G400 is an intelligent double-head drilling and milling machining center machine tool. The bed is made of high-strength HT300 gray cast iron, with dual spindles and tool magazines, adopting a mechatronic integrated design. It has an elegant appearance and can perform precision cutting. Once the workpiece is clamped, the machine can automatically complete milling, drilling, boring, expanding, reaming, countersinking, tapping, and other processes continuously.
This machine is suitable for processing a variety of parts such as medium and small-sized box-type, plate-type, disk-type, and shell-type components.
Bed: The bed adopts a classic high-rigidity C-type structure, with stress paths shortened and rigidity improved through finite element analysis and topological optimization. Major components are made of HT300 cast iron material, subjected to stress relief annealing and natural aging treatment for over six months. The X, Y, Z axes use P-grade linear roller guides, providing high rigidity, stability, and reliability.
Spindle: Dual-spindle structure with BT30 built-in spindle, maximum speed of 20000RPM.
Tool Magazine: Dual tool magazine structure, with reliable arm-type tool magazine, 21-tool capacity, and fast tool change time.
Drive: The three-axis motors and high-precision ball screws are directly driven to enhance transmission rigidity and positioning accuracy. All three linear coordinate axes use linear roller guides, resulting in minimal vibration during high-speed feed and no creeping during low-speed feed.
The dual - spindle drilling and milling center machine has the following characteristics:
I. High processing efficiency
1. Dual - spindle design
• The dual - spindle drilling and milling center machine is equipped with two spindles, enabling simultaneous processing of workpieces. For example, when processing some symmetrical - structure parts, one spindle can be responsible for drilling operations on one side, while the other spindle can perform milling operations on the other side simultaneously, greatly shortening the processing time.
• Compared with single - spindle machines, dual - spindle machines can complete more processing procedures in one clamping, reducing the transfer and re - clamping time of workpieces between different machines and improving the overall production efficiency.
2. High - speed cutting capability
• This type of machine is usually equipped with high - speed electric spindles, enabling high - speed cutting. High - speed cutting can not only increase the processing speed but also obtain better surface quality of the processed parts. For example, when milling aluminum alloys and other materials, high - speed cutting can reduce tool wear and improve processing accuracy.
II. High processing precision
1. High - precision spindles
• The spindles of the dual - spindle drilling and milling center machine usually have high rotational precision. The radial run - out and axial run - out of the spindles are controlled within a very small range, ensuring high - precision processing of holes and planes.
• For example, when processing some precision molds, the high precision of the spindles can ensure that the dimensional accuracy and surface roughness of the molds meet high requirements, reducing subsequent grinding and polishing processes.
2. Stable structure design
• The bed and columns of the machine tool are generally made of high - strength cast iron or welded steel structures, which have undergone aging treatment to eliminate internal stresses and ensure the stability of the machine tool during high - speed processing. This stable structure design can reduce vibrations during the processing process, thereby improving processing precision.
• When drilling deep holes, the stable structure can prevent the deviation of the drill bit, ensuring the straightness and cylindricity of the holes.
III. Multi - functionality
1. Integration of multiple processing techniques
• The dual - spindle drilling and milling center machine can integrate multiple processing techniques such as drilling, milling, and boring. It can complete all or most of the processing procedures of complex parts on a single machine, reducing dependence on different types of machine tools.
• For example, when processing a box - shaped part with multiple holes and complex contours, the machine tool can first use the drilling function to process each hole, and then use the milling function to process the contours and planes, achieving seamless connection of processing techniques.
2. Flexible tool configuration
• The machine tool is usually equipped with an automatic tool - changing device (ATC) that can store and change multiple tools. This enables the machine tool to quickly change tools according to different processing requirements and switch between different processing techniques.
• For example, when processing a part with both drilling and milling features, the machine tool can quickly change the milling cutter through the automatic tool - changing device after completing the drilling process.
IV. High degree of automation
1. CNC system control
• The dual - spindle drilling and milling center machine is generally controlled by an advanced CNC system. Operators only need to input processing parameters through programming, and the machine tool can automatically complete the processing process. The CNC system also has a graphic simulation function, which can simulate the processing process before processing to check the correctness of the program and avoid processing errors.
2. Automated loading and unloading
• Some high - end dual - spindle drilling and milling center machines can also be equipped with automated loading and unloading devices to achieve automatic loading and unloading of workpieces. This not only further improves production efficiency but also reduces errors and safety hazards caused by manual operations.
• For example, when producing parts in batches, the automated loading and unloading devices can continuously provide workpieces for the machine tool and take out the processed workpieces, achieving automated operation of the production line.
The dual - spindle drilling and milling center machine, with its characteristics such as high processing efficiency, high precision, multi - functionality, and high degree of automation, is widely used in the field of mechanical processing.
