Can be equipped with a fourth and fifth rotation axis to meet the processing requirements of special parts.

1.3Main structural features

The main foundation components such as the base, slide, worktable, column, and spindle box are all cast with high-strength HT300 cast iron material and resin sand technology. The base is a box type structure, and the compact and reasonable symmetrical reinforcement structure ensures the high rigidity and bending and shock absorption performance of the foundation components; The A-type bridge span column and internal grid like reinforcement effectively ensure the rigidity and accuracy during Z-axis strong cutting; The basic components are molded with resin sand and undergo aging treatment, providing stability for the long-term performance of the machine tool.

X. The Y and Z guide rails are both heavy-duty linear roller guides from original Taiwan HIWIN or PMI companies, with low friction coefficient, high worktable sensitivity, low high-speed vibration, no crawling at low speeds, high positioning accuracy, and excellent servo drive performance; At the same time, it has a high load-bearing capacity and good cutting anti vibration performance, which can improve the performance characteristics of the machine tool, enhance the accuracy and stability of the machine tool, and extend its service life.

X. The Y and Z directions are fed using high-precision and high-strength internal circulation double nut preloaded large lead ball screws with high feed speed; The drive motor is directly connected to the screw through an elastic coupling, and the feed servo motor directly transmits power to the high-precision ball screw without backlash, ensuring the positioning accuracy and synchronization of the machine tool;

The Z-axis motor is equipped with an automatic brake function. In the event of a power outage, the automatic brake will hold the motor shaft tightly, preventing it from rotating.

The spindle assembly is produced by a professional factory in Taiwan, which has high speed, high precision, high rigidity, and strong axial and radial bearing capacity. The spindle gripping tool relies on the butterfly spring on the spindle to exert tension through a four petal claw type pulling mechanism on the pull pin of the tool handle, and is achieved by the tight fit between the tool and the spindle taper hole.

The spindle adopts a central blowing structure, which quickly cleans the inner cone of the spindle with central high-pressure gas when the spindle loosens, ensuring the accuracy and service life of tool clamping.

The machine tool has a spindle orientation function.

High precision pitch compensation, each transmission shaft adopts high-precision laser for detection and optimization compensation, making the positioning accuracy of each axis more accurate and more suitable for processing high-precision parts. At the same time, advanced ball bar instruments are used to optimize analysis and processing, ensuring the accuracy of the machine tool in circular and curved surface machining.

1.4 Machine tool protection

X. The Y and Z direction guide rails and lead screws are equipped with protective devices to ensure the cleanliness of the lead screws and guide rails, and to ensure the transmission and motion accuracy and service life of the machine tool;

The machine tool adopts a fully enclosed and environmentally friendly protective structure design, which is easy to operate, safe and reliable, beautiful and generous, effectively preventing iron filings and coolant splashing, allowing operators to work in a safe and comfortable environment.

1.5magazine
