3、机床特点：
  • 机、电、液一体化及模块化设计，布局合理，结构紧凑，操作宜人。
  • 床鞍，滑体与导轨复合面均贴有聚四氟乙烯导轨板，摩擦系数小，动态性能好，耐磨损。
  • 采用高性能的变频电机，变速范围宽，可实现无级自动变速。
  • 进给驱动采用高性能的交流伺服电机，定位精度高，性能稳定可靠。
  • 进给采用过载保护装置，过载保护力矩的大小可根据加工情况预先设定并可调整，能有效地保护刀具、丝杠及电机。
  • 工件支承一端采用卡盘夹持，一端由中心架支承。所配中心架刚性好，可沿床身方向运动及锁紧，能更好地支承工件。
  • 钻杆支架可沿床身方向运动及锁紧。支架前端为旋转部件，可与工件同时旋转并进行端面密封；后端为固定支承部件，由卡盘和密封导向套等组成，能支承和引导钻杆（根据规格不同其密封导向套是可换的）。钻杆支架上有高压切削液接口，高压切削液由此处进入介于钻头和已钻削孔之间的空间，钻杆本身是空的，切削液携带切屑进入钻体，流经钻头内的排屑槽，然后排出钻管。
  • 润滑装置能确保润滑充分可靠。
  • 采用单管钻系统，刀杆刚性好，生产效率高。
