Key Features:
The TX-300 series CNC belt grinder is derived from our company's invention patent: a six-axis linkage CNC belt grinder with a horizontal multi-belt mechanism. At the beginning of the design, it was aimed at the integrated grinding needs of aircraft engine and gas turbine compressor blades with a chord width of less than 300mm. At the same time, two sets of grinding devices, electric spindle and belt, were configured to grind different characteristic positions of the blades. This model can meet the high-precision, high-performance integrated grinding of aircraft engine blades, gas turbine compressor blades, and square steel integrated processing blades with a total length of less than 500mm and a chord width of less than 300mm. It can complete the grinding of the blade body surface, intake and exhaust edges, edge plates and blade root fillet transition zone in one clamping. When equipped with an in-machine detection system and software, it can realize the measurement of blade clamping errors and blade deformation errors and model reconstruction adaptive processing.Later, with the differences in the use requirements of different users, this model formed the following
