Description

Technical Field

[0001] The invention relates to the technical field of aluminum veneer processing, and in particular to a polishing device for aluminum veneer processing. Background Art

[0002] In the processing of aluminum veneer, commonly used polishing devices include polishing machines, polishing discs and polishing liquids. Polishing machines are specially designed for polishing aluminum veneers. They are usually driven by motors and can control the polishing effect by adjusting the speed and polishing pressure. Polishing discs are rotating disc-shaped tools installed on polishing machines. Polishing cloths or polishing pads can be installed to grind and polish the surface of aluminum veneers. Polishing liquids are used to increase the polishing effect and improve the surface finish.

[0003] Conventional polishing devices are usually manually operated for polishing. However, during manual polishing, the polishing wheel may be unstable, resulting in uneven polishing effect. In addition, due to the influence of manpower, the polishing speed is slow, which limits production efficiency and output. Existing automatic polishing machines are usually suitable for small-sized and relatively simple workpieces. The polishing effect may not be good for larger aluminum veneers, and they cannot be adaptively fixed according to the specifications of aluminum veneers. The polishing wheel is generally driven by a fixed program and is difficult to flexibly adjust according to actual conditions. For example, when the surface polishing effect of the aluminum veneer is not good and further polishing is required, the movement trajectory of the polishing wheel has been set in advance, and the position of the polishing wheel cannot be flexibly adjusted, which affects the final polishing effect.
