[Xilin Gol wedge wedges picture Gol Guoxiang iron wedges wedges] the first for the initial phase of the plant (early in 1882, Shanghai in Shanghai Concession British electro-optical company established, then China will have a power plant) with Installation and adjustment of the steel beam to adjust the parallelism and mechanical equipment work, until today Guoxiang wedges are widely used in power plants, metallurgy, machinery, chemicals, shipbuilding, scientific research, environmental protection, aerospace, automotive, agricultural machinery, electrical, instrumentation, medical equipment , hardware and other production areas for China's construction and development has made a great contribution. Delivery wedges parallel and horizontal adjustment for various equipment, the equipment vibration does not occur during operation, tilt, ensure the machine is in operation during the level reached in good condition, reduce machine wear, saves money and machinery replacement parts. Wedges slope of 1/10 --- 1/20, you can also design their own slope by slope ratio may not be produced tapered wedges choose according to the specific needs of a given accuracy domestic surface table finish with a surface roughness Ra, Rz value conversion table (unit: μm) surface finish ▽ 1 ▽ 2 ▽ 3 ▽ 4 ▽ 5 ▽ 6 ▽ 7 surface roughness Ra 50 25 12.5 6.3 3.2 1.6 0.8 Rz 200 100 50 25 12.5 6.3 6.3 surface finish ▽ 8 ▽ 9 ▽ 10 ▽ 11 ▽ 12 ▽ 13 ▽ 14 surface roughness Ra 0.4 0.2 0.1 0.05 0.025 0.012 - Rz 3.2 1.6 0.8 0.4 0.2 0.1 0.05 Attachment: old finish is called, in 90 years after the state tolerance standard changed the call roughness, the above figures refer to the micro, the parts of the surface irregularities of the radius of the arc you are working in microns, the old standard is the new standard of China 8 7 1.6 0.8 China, Hua 6 is 3.2, China 5 6.3 4 12.5 Hua Hua 25. 3 is the new standard part surface roughness of 3.2 micro-see marks, but not 1.6 marks, 0.8 is the visibility of human images, the same price than the 0.4 is the mirror the quality of the same quality of service than the day of delivery wedges [Gol Gol Gol Guoxiang picture iron wedge wedges]
