品牌：NTH
切削抗震设计 手臂张开设计 无弹簧无磨损
MECHANISM FOR OPENING THE ARMS OF THE STEADY REST WITHOUT SPRINGS AND FREE FROM WEAR.AND ANTI-VIBRATION DESIGN FOR MACHINING.
润滑 选配 OPTION OF LUBRICATION
手动润滑：低润滑，用于中等工作条件，小切削量
集中润滑：由于恶劣工作条件下，大切量
油气润滑：用于大切削量，粉尘或强力冷却的条件下
Manual lubrication: Low cost solution for medium working conditions and low swarf.
Central lubrication: For heavy working conditions and high build up of swarf
Central lubrication oil and air: For heaviest cutting conditions with high built up of swarf,dust or coolant
滚轮 选配 OPTION OF LUBRICATION
