There may be some downsides in the price of alloy tubes, but the space is not large, because there are many cost factors such as labor costs, which are rigid and cannot be reduced. E-commerce is not a good business because of low profit margins, long return on investment, and low win rate. As a consumer, I really want to be grateful to these e-commerce companies in China. They made the price of the product transparent and provided me with cheap products and logistics services. However, if I am an investor, I may be in another mood.

Precision Grinding And Polishing Machine
Ultra-precision cutting Ultra-precision cutting refers to the cutting method whose surface roughness is less than Ra0.04μm. The key problem in ultra-precision machining is that the thin surface layer of 0.1μm is cut in the final step. This requires both an extremely sharp tool with a radius of the blunt circle of the tool at the nanoscale and a tool with enough durability to keep it sharp. At present, only diamond tools can meet the requirements. In ultra-precision cutting, the cutting speed should be very high and the cutting amount should be small to ensure that the residual area on the workpiece surface is small, so as to obtain minimal surface roughness
