Select the Appropriate Machine Tool According to the Shape and the Size of Parts
Because of the complex shape with lots of surface and negative angles, 5-axis machine tools must be used when drilling, milling and grinding complex-shape hard materials (over HRC50) with an accuracy of 5-10 μm. During which grinding is the key process, therefore, it is very important to choose a 5-axis machine tool with high basic accuracy, good stability and key components.
Key Configuration
JD130S-24-BT30 High-speed Precision Spindle
With low vibration and good thermal stability, it can realize long time stable precision grinding.
Grinding Protection System Protects Key Parts of Machine Tool
Prevent the grinding chips from entering the inner of machine tool, reduce the wear of the rail and screw, and ensure the accuracy of the machine tool.
High Precision Grinding Filtration System
Adopting 4-stage filtration, and the filtration accuracy is 25μm.
The Grinding Wheel Trimming System Helps Maintain the Grinding Capability.
After working for a long time, the grinding wheel will be clogged or abrasive passivated, which will lead to the decrease of grinding capability. In order to improve the grinding capability, the grinding wheel trimming system can trim on-line.
The Automatic Measuring Device of Grinding Wheel Diameter Replaces the Manual Tool Set and Obtains the Actual Diameter of the Grinding Wheel.
The diameter of the grinding wheel needs to be measured for the first use, and using this device can reduce the probability of overcutting and scratching the side wall of hole. After trimmed, using this device can reduce the manual measurement error.
