（2） Main technical characteristics of machine tool design

1. The main parts of the machine tool, such as the bed frame, column, saddle, worktable, and spindle box, are made of high-quality gray cast iron with high seismic performanceISO9000Professional enterprise production with quality system certificationThe casting process adopts special processing techniques to improve the mechanical properties of the material. The casting undergoes two aging treatments to eliminate residual stresses inside the material. Therefore, when machine tools are used for heavy or intermittent cutting, they have excellent rigidity and excellent shock absorption; Simultaneously possessing good thermal stability and persistent accuracy stability. The machine tool design adoptsX/Y/ZThe structure of the axial track adopts heavy preloading for all three directional tracksThe machine tool not only combines the characteristics of high speed and high precision, but also has the characteristics of heavy cutting, with excellent rigidity and production efficiency.

2. All key components of the optical machine are constructed using advanced 3D technologyCADThe software is designed and advanced computer finite element analysis is used to determine the optimal structure of the components. The bed, columns, saddle and other parts are designed with large cross-sectional dimensions, and the guide rails are designed with large spans, thus making the machine tool have excellent strength, rigidity and thermal stability.

3. The main joint surfaces of the optomechanical assembly are manually scraped to ensure the effective contact area of the joint surfaces.

4. The spindle adopts precision spindle units produced by professional manufacturers, and the spindle bearings are all high-precision angular contact thrust ball bearings from world-renowned brands, ensuring that the spindle has extremely high precision and rigidity. The spindle and motor pulley have undergone dynamic balance testing to ensure spindle accuracy and lifespan. The front end cover of the spindle adopts an air curtain protection function to prevent the invasion of air, dust, and chip fluid. And the spindle has a blowing function. Before each tool change, compressed air is blown through the middle of the spindle to clean the taper hole and tool holder inside the spindle, remove any residue on the taper hole and tool holder, thereby improving the bond between the spindle and the tool, and further ensuring the high rigidity of the bond between the spindle and the tool.

5. The feed component of the machine tool adopts imported high-precision ball screws, and both ends of the support bearings are made of imported screw special bearings, and the ball screws are pre stretched; The screw motor connection adopts a gapless elastic coupling, which ensures seamless transmission, small moment of inertia, and high transmission stiffness. The machine tool guide rail pair adopts linear guide rails imported from Taiwan. The lead screw and guide rail are equipped with a centralized automatic lubrication device, which automatically supplies oil to the lead screw and guide rail at a fixed time and quantity, ensuring sufficient lubrication during the movement of the machine tool, thereby ensuring excellent fast response characteristics and low-speed feed performance, longer service life, and better accuracy retention.

6. Machine toolI/OPartially using printed circuit boards andCNCThe control part is highly integrated, greatly reducing the failure rate, making the wiring neat and the structure reasonable. Electrical cabinet heat dissipation device.
