The semi-automatic grinding machine series offers various options to meet different processing needs. The advantage of this series lies in its relatively lower investment cost, making it an ideal choice for budget-conscious enterprises.
For applications requiring greater flexibility in feed directions, the dual-axis automatic (2A) series is a more suitable choice. This machine can handle complex-shaped workpieces, meeting higher-level grinding requirements.
For more complex machining requirements, the three-axis automatic (3A / AH) series offers advanced functionalities. This series allows for quick vertical infeed for enhanced machine flexibility and broader adaptability.
Features
- Multiple Standard Worktable Sizes: Provide 6 inches x 18 inches, 8 inches x 18 inches, 10 inches x 20 inches (2550), 12 inches x 25.5 inches (3060), 16 inches x 32 inches (4080).Multiple worktables are available to meet common machining needs in the market. The cross infeed adjustment of the worktable can reach 0.02mm, and the optional M series fine adjustment device allows for precise adjustments of up to 0.002mm.
- Spindle: Utilizing V-3 grade motor direct drive. With minimal transmission error and excellent lubrication, it can effectively extend the spindle's lifespan. The vertical feed adjustment of the grinding wheel head can reach 0.005mm.
- and the optional M series fine adjustment device allows for precise adjustments of up to 0.001mm.
- Rigid Structure: The machine structure is made of advanced Meehanite cast iron, ensuring optimal machine rigidity and vibration resistance.
