Three-axis rail high-speed and high-accuracy machining central machine
Advantages of the product
The heavy-duty roller type guide rails of Taiwan or German brand, and Taiwan spindle with an external diameter of 150mm are applied to the three axes; the product can effectively cool the spindle that runs at high speed in connection with Tongfei oil cooler which is shared with the Beijing Jingdiao CNC machine tool, thereby improving the service life of the spindle and reducing thermal elongation due to temperature rise of the spindle; and accordingly the machining accuracy is improved.
The tool magazine is designed as the fully-sealed structure which can effectively prevent the spattering iron scraps from adhesion to the tool magazine; therefore, fault of the tool magazine is greatly reduced, and the fragments generated by the spindle are discharged. In this way, the cost is increased, while many manufacturers are reluctant to increase; however we will never cut down materials!
Introduction of structure of the machine tool body
We know very well that the machine tool body is the core foundation of the machine tool; thus, we pay more attention to material and machining accuracy of the casting. The strong strengthening ribs are used in the casting and distributed reasonably, to ensure stability and rigidity of the machine tool body. Further, the geometric accuracy are strictly controlled during installation and adjustment of three axes, and the three-axis screw rod is subjected to strict prestretching; and in connection with the exquisite scraping process and balanced torsion screw, the machine tool is very stable, and the machining accuracy is ensured.
