◆ Customization Services for Customers

2.1 Machining Process Customization

We develop exclusive grinding process plans based on workpiece material, shape, size, precision requirements and production batch. For high-hardness materials, we select suitable grinding wheel materials and parameters to ensure efficient and high-precision grinding. For high-precision workpieces, we formulate refined grinding procedures (multi-pass feeds, variable grinding speeds and feed rates) to achieve micron-level accuracy.

2.2 Automation Customization

To boost productivity and reduce labor costs, we can configure automatic loading/unloading devices, workpiece transfer systems and robot collaboration systems as required. Automatic loading/unloading manipulators realize automated clamping and unloading, shortening manual operation time and improving consistency of machining accuracy. Automated transfer lines can integrate multiple grinding machines to form an automated grinding production line for seamless workpiece flow between processes.

2.3 Machine Function Customization

We expand or optimize machine functions for special machining needs. An on-line measuring system enables real-time dimension measurement and feedback during grinding, allowing timely parameter adjustment to guarantee workpiece accuracy. An automatic grinding wheel dressing device dresses the wheel per preset programs, maintaining wheel sharpness and profile accuracy to improve grinding quality and efficiency.

2.4 Fixture Customization

We design and manufacture special fixtures for specific workpieces to ensure positioning accuracy and stability during clamping, enhancing machining efficiency and quality. For special-shaped disc workpieces, dedicated electromagnetic chucks or mechanical fixtures enable fast and accurate clamping, preventing workpiece deformation and displacement during grinding.

2.5 Appearance & Layout Customization

We customize the machine's appearance (color, dimensions) to match the factory layout and aesthetic requirements. The machine color can be coordinated with the factory's overall tone, and the outline dimensions can be optimized to fit workshop space and improve space utilization.
