MECHANISM FOR OPENING THE ARMS OF THE STEADY REST WITHOUT SPRINGS AND FREE FROM WEAR.AND ANTI-VIBRATION DESIGN FOR MACHINING.
潤(rùn)滑 選配 OPTION OF LUBRICATION
手動(dòng)潤(rùn)滑：低潤(rùn)滑，用于中等工作條件，小切削量
集中潤(rùn)滑：由于惡劣工作條件下，大切量
油氣潤(rùn)滑：用于大切削量，粉塵或強(qiáng)力冷卻的條件下
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
滾輪 選配 OPTION OF LUBRICATION
NTH-OMSR滾輪（精度等級(jí)P05）是專為中心架設(shè)計(jì)
特殊的密封保證了的精度和使用壽命
標(biāo)準(zhǔn)配置：圓柱型滾子1套
選配：腰鼓型滾子用于跟刀式應(yīng)用的中心架
Omatei rollers (precision class P05) specially developed for our Steady Rests
Special sealing ensures highest precision and service life
Standard equipment: 1 set of cylindrical rollers
Option: Spherical rollers (for travelling Steady Rests)
