Product details
◆ This machine belongs to the field of surface finishing, which is used to improve the surface roughness of the workpiece, and its shape accuracy is guaranteed by the previous milling process.
◆ It belongs to flexible grinding. Because of the control of servo pressure shaft, the contact wheel and moving belt constantly adjust the grinding force to make it constant, which is also called constant force grinding.
◆ "6 + 1" axis control technology: 6 axes (XYZ, ABC) linkage + 1 servo pressure axis.
◆ Typical machined part: turbine blade, see the figure below.
At present, the vast majority of blade polishing adopts manual polishing, which has high labor intensity and difficult to ensure the quality. With the increasing size of the workpiece, the labor is not competent. The domestic key blade manufacturers purchase imported equipment for processing, which is expensive and costly; Technology is complex, especially the programming requirements are high, foreign technical services are often not guaranteed. Therefore, the cost-effective advantage is silent and can completely replace imports.
