Three-axis rail high-speed and high-accuracy machining central machine
Advantages of the product
The guide rail, which is greater than that of common 850 type machine and 45mm wide, is applied to the bearing axis; the power of the spindle motor can achieve 15KW (whether to change as the high-power spindle motor shall be reconfirmed). In connection with the stable machine tool base, the bearing axis can be taken as a small "King Kong".
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 accordingly the machining accuracy is improved.
The tool magazine is designed as a fully-sealed structure which can effectively prevent the spattering iron scraps from adhesion to the tool magazine; therefore, the fault of the tool magazine is greatly reduced, and the service life and accuracy of the spindle are improved.
Structure introduction of the machine tool body
on the basis of 850 type machine, this type of machine tool uses the super-wide lambdoidal structure and widened span between the guide rails, in order to improve the rigidity of the machine tool. In connection with 45mm heavy-duty roller type guide rails, the machining rigidity of the bearing axis much superior to that of common 850 machine tool.
