● 由四個超精密度斜角滾珠軸承支撐，精度高、壽命長，且採用高轉速之潤滑脂，不需再作潤滑工作。
● 主軸座與馬達座採一體成型，穩固剛強，完全密封，可確保主軸精度。
● 主軸馬達採用 V-3級低振動強力馬達，適合重研削。
●

Composed of four precision inclined ball bearings to ensure high precision and long duration of operation, the shaft also adopts high-speed grease to avoid routine lubrication.

● One-piece formed base for shaft and motor, which is sealed completely to firm the foundation and have a high precision in shaft.
● Motor used for the shaft is V-3 grade low virbration motor which is suitable for various heavy machining.
● 平面及切溝研磨時，砂輪向下自動進刀，每次進刀量從 0.002mm~0.02mm，有10段可供選擇，研磨深度可先行設定，達到此深度時，砂輪即停止進刀。
●

While grinding in surface and ditch-cutting, the sander will auto matically feed downward, with a feeding capacity ranging from 0.002mm to 0.02mm and tem different speeds serving as options, The grinding depth is available by setting in advance. When grinding reaches the set depth, the sander will stop auto-matically.
