機床特點 Features of machine tools
1.CKD51 系列雙絲杠提升數控立式車床，采用雙絲杠提升橫梁。立柱、床身、橫梁、底座特殊設計，使機床具有高剛性、
高穩定性、高精度、實現強切削功能。適用于硬質合金及陶瓷等刀具，對黑色金屬、有色金屬及部分非金屬零件的內外
圓柱面、圓錐面、切槽、螺紋及回轉曲面等進行粗、半精、精加工。
2. 立柱為熱對稱結構，通過計算機有限元計算，采取有效的隔振措施，具有高剛度、高抗震能力。
3. 導軌面采用高頻淬火，硬度 HRC40-45 度。
4.CKD5112、CKD5116 兩種機型，工作臺采用滾動軸承導軌，主軸采用高精度圓錐孔雙列圓柱滾子軸承，主軸軸向間隙采
用推力球軸承調節，極大提高了承載能力，運行速度更快，加工精度有質的提升，變速箱也重新設計，加大齒輪模數，齒

轉速度比普通立車高，加工精度高等特點，特別適合火車輪，橋梁支座等斷續切削，重切削加工。

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.
