This machine tool is a vertical machining center suitable for machining and mold manufacturing. It can meet the processing requirements from rough machining to finishing, and can complete various processes such as milling, drilling, tapping, and boring.
Main structural features
●The machine body and main components are all high-strength cast iron with stable metallographic structure to ensure the stability of the machine tool for long-term use;
●The bottom of the column is an A-shaped bridge-span structure, combined with a large box base, which greatly reduces the vibration of the machine body during heavy cutting;
●Pre-stretched precision ball screw drive;
●High-speed, high-precision, high-rigidity spindle unit;
●Oil-water separation design;
●Intermittent automatic lubrication;
●Pneumatic loosening and broaching system
Detailed description
1. The machine body and main castings are made of No. 300 lime-soil cast iron, and the tempering failure treatment can ensure the accuracy and endurance of the machine tool, and it will not be deformed for a long time.
2. Spindle design features
The spindle bearing is designed with a combined angular ball bearing configuration, which can maintain the rigidity, accuracy, and life of the spindle for a long time at high speed. The spindle head is designed with a box-shaped mechanism, which is strengthened internally, with high rigidity and stability, and is suitable for heavy cutting.
Spindle bearing assembly method: liquid nitrogen cooling method and electromagnetic temperature method are used to ensure:
① The matching accuracy of the main shaft and the bearing
② The bearing pairing has been tested for high-speed dynamic balance to ensure the concentricity and eccentricity of high-speed rotation.
The head counterweight is nitrogen counterweight, which makes the head up and down movement stable, safe and noise-free.
3. Column design
The column has a large contact area with the base. The column adopts a honeycomb structure, which not only improves the torsional rigidity of the structure, but also effectively improves the resonance of the low-frequency structure to ensure * stability.
4. Precision ball screw
Three-axis precision ball screw, X-axis: 50×10, Y-axis 55×12, Z-axis 50×10 pitch, direct drive and pre-tension design. Improved accuracy, rigidity, and life are the best configuration for long-term maintenance of cutting accuracy and durability.
5. Transmission structure
Synchronous belt is used to connect the main shaft.
6. Fully automatic lubrication system
It adopts fully automatic lubrication system and computer program to control the lubrication time, which is convenient
Look at the oil gauge and oil addition to ensure the accuracy and life of the machine.
7. Internal protection
The three-axis telescopic shield can prevent cutting fluid and coolant from damaging the guideway surface, ensuring price accuracy and guideway life. The specially designed mechanical guard action makes chip removal easy.
8. Linear guide
The X-axis of the machine tool is equipped with a 55-wide roller-type linear guide of Taiwan Shangyin, 3 slides on one side, and the Y-axis is equipped with 4 45-wide roller-type linear guides. The Z-axis is a hard track, which has fast moving speed, high precision and stability. Good sex.
9. Quality assurance
Each machine tool has undergone a long-term continuous running-in test before shipment to ensure high-quality operability and stability.
10. Cutting test
Before shipment, each machine undergoes cutting test and 24-hour continuous rotation test.
