(Column Series) Semi-Automatic Precision Surface Grinding Machine | Joen Lih: Precision CNC Grinding Machines for Medical & Semiconductor Industries

(Column Series) Semi-Automatic Precision Surface Grinding Machine is driven by a hydraulic system, this drive mode is less prone to vibration, effectively preventing the generation of threads on the workpiece surface, thereby enhancing processing quality. The sliding surface is made of low-friction, wear-resistant Turcite-B (wear-resistant material), and undergoes precise scraping treatment, enabling smooth and effortless movement of the worktable. The main structure is made of high-quality cast iron, ensuring the machine's robust rigidity, resistance to deformation, and maintaining the stability of machining accuracy. To better meet the practical needs of customers, Joen Lih has specifically designed multiple standard worktable sizes based on common workpiece dimensions. This allows customers to choose the most suitable grinding machine according to their actual machining cases.
