Features
1. The hydraulic surface grinder is a top seller among all the similar products by virtue of rational structure, excellent rigidity, elegant profile and simple operation.
2. The transverse motion of working table is hydraulically driven and the front and back electric devices are optionally provided upon the specific requirement.
3. The P4 grade precision rolling bearing is adopted as the spindle bearing. The spindle is equipped with a labyrinth seal. Therefore, it has an excellent performance in water and dust prevention.
4. The hydraulic surface grinder has unexpected functions in grinding various flat or complicated surfaces, especially suitable for abrasive machining without mechanical feed. It is optionally available with a permanent or electric magnetic chuck.
