(250 x 500 mm) CNC Hydraulically Precision Surface Grinding Machine

JL-2550CNC-H

CNC Hydraulically Precision Surface Grinding Machine (JL-2550CNC-H) is hydraulically driven, realizing cost-effective benefits through a hydraulic cylinder system.

This grinder adopts a two-axis contouring and dressing sanding technique, coupled with servo motors. It not only comes at an affordable price but also becomes the preferred choice for customers requiring only dual-axis contouring positioning.

When customers have flat grinding needs, it provides a cost-effective machining solution.

Features

  • Drive Mechanism: Driven by a hydraulic system, the operating mode prevents the generation of threads on the workpiece surface. Particularly suitable for flat grinding, it achieves superior Ra values, enhancing the smoothness and overall precision of the workpiece surface.
  • Longitudinal Worktable: The worktable area is 250 x 500 (mm). Adopting a dual V-guide design, it effectively reduces vibration and rocking, ensuring high processing precision. 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.
  • Intelligent Electrical Control System: Positioning control ensures that the contouring and dressing sanding process follows preset parameters. Its interface is clean and user-friendly, effectively reducing the risk of human errors. Moreover, by recording key data, the system allows for subsequent optimization of the contouring and dressing sanding process, further enhancing production efficiency and product quality.
  • Grinding Wheel Spindle: Driven by induction motors, providing precise control. Strong adaptability to cope with diverse processing environments.

Application

  • Focused on flat grinding, it achieves excellent Ra values.
  • Automotive template grinding.
