1. Ckd51 series double screw lifting CNC vertical lathe adopts double lead screw to lift beam. The special design of column, bed, beam and base makes the machine tool have high rigidity, high stability, high precision and powerful cutting function. It is suitable for cutting tools such as cemented carbide and ceramics to rough, semi finish and finish the internal and external cylindrical surface, conical surface, groove, thread and rotary surface of ferrous metal, non-ferrous metal and some non-metallic parts.
2. The column is a thermally symmetric structure, and effective vibration isolation measures are taken through computer finite element calculation, which has high stiffness and high seismic capacity.
3. The guide rail surface is quenched with high frequency, and the hardness is hrc40-45 degrees.
4. For ckd5112 and ckd5116 models, the table adopts rolling bearing guide rail, the main shaft adopts high-precision tapered hole double row cylindrical roller bearing, and the axial clearance of the main shaft adopts thrust ball bearing adjustment, which greatly improves the bearing capacity, the running speed is faster, and the machining accuracy is improved qualitatively. The gearbox is also redesigned, and the gear module is increased, the tooth surface is widened, and the gear coincidence degree is increased The transmission shaft and bearing are also improved. They have the characteristics of large bearing capacity, impact resistance, friction resistance, stable operation, long service life, higher running speed than ordinary vertical lathe, and high machining accuracy. They are especially suitable for intermittent cutting and heavy cutting of train wheels, bridge bearings, etc.
