Product Details◆ This machine tool belongs to the category of surface finishing processing and is used to improve the surface roughness of workpieces. Its shape accuracy is guaranteed by the previous milling process.◆ It belongs to flexible grinding, because with the control of the servo pressure shaft, the contact wheel drives the abrasive belt to continuously adjust the grinding force, making it constant, also known as constant force grinding.◆ “6+1” axis control technology: 6 axes (X\Y\Z, A\B\C) linkage + 1 servo pressure axis.◆ Typical processed parts: turbine blades, see the figure below.Currently, the vast majority of blade polishing uses manual grinding, which is labor-intensive and difficult to ensure quality. As the workpiece size becomes larger and larger, manual methods are no longer sufficient. Domestic key blade manufacturers purchase imported equipment for processing, which is expensive and costly; the technology is complex, especially the programming requirements are high, and foreign technical services often cannot be guaranteed. Therefore, the cost-effectiveness advantage is self-evident, and it can completely replace imports.
