1. HT300 cast iron is used for the base, sliding seat, workbench, column, headstock and other main foundation parts; The base is a box-type structure, and the compact and reasonable symmetrical reinforcement structure ensures the high rigidity, bending and vibration reduction performance of the foundation; A-type bridge span column and internal grid reinforcement effectively ensure the rigidity and accuracy of Z-axis strong cutting; The base parts are molded with resin sand and subject to aging treatment, which guarantees the stability of the long-term service performance of the machine tool.   2. The X, Y and Z direction guide rails are the heavy-load linear ball guide rails of Taiwan Shangyin or Yintai Company, which have the characteristics of high speed, high rigidity, low friction, low noise, low temperature rise and change, and are equipped with automatic forced lubrication to improve the accuracy and life of the machine tool; The X/Z axis six-slider design improves the machining rigidity of the machine tool.   3.The X, Y and Z directions adopt high-precision and high-strength internal circulation double-nut pre-pressing ball screw with large lead, and the feed speed is high; The drive motor is directly connected with the lead screw through the elastic coupling, and the feed servo motor directly transfers the power to the high-precision ball screw without backlash, ensuring the positioning accuracy and synchronization of the machine tool;   4. High speed, high precision and high rigidity spindle unit is adopted, with strong axial and radial bearing capacity, and the maximum speed can reach 12000 rpm;   5.The main shaft adopts a central blowing structure. When the main shaft looses the tool, it quickly uses the central high-pressure gas to clean the inner cone of the main shaft to ensure the accuracy and life of the tool clamping;   6.The guide rail and lead screw in X, Y and Z directions are equipped with protective devices to ensure the cleanness of the lead screw and guide rail, and ensure the transmission and movement accuracy and service life of the machine tool;   7.The external protection of the machine tool is designed with full protective structure, which is convenient to operate, safe and reliable, beautiful and generous;   8.Reliable centralized automatic lubrication device is used to automatically and intermittently lubricate each lubricating point of the machine tool at a fixed time and a fixed quantity, and the lubrication time can be adjusted according to the working conditions;   9.24 disc-type tool libraries (optional) produced by professional manufacturers in Taiwan are adopted, which are accurate in tool change, short in time and high in efficiency. After millions of operation tests, they meet the reliability requirements; With damping structure, it can reduce the impact during movement and ensure the service life of tool magazine; Pneumatic drive, easy to use, shortest path tool change;   10.The simple oil-water separation device can separate most of the collected lubricating oil from the coolant, prevent the rapid deterioration of the coolant, and is conducive to environmental protection;   11.The machine tool operating system adopts the ergonomic principle, and the operation box is designed independently, which can rotate and operate by itself Convenient.
