A kind of diamond wire saw for cutting reinforced concrete with low cost and high performance

The effect of new superfine pre-alloyed powder and vulcanization of rubber on the cost and property of diamond wire saws were studied, which were used to cut reinforced concrete.A new diamond wire saw with low cost and high performance was developed and produced by using new superfine pre-alloyed powder, structure improvement of the diamond wire saw and optimization of the vulcanization process of rubber.The diamond wire saw was tested by cutting highly reinforced concrete crossbeam (the ratio of sectional area of steel bar to beam cross section >0.09) and the result of the test was analyzed.The result showed that the diamond wire saw used in the test has excellent sharpness and long lifetime with cutting speed achieved 2.0~2.8 m²/h and the lifetime achieved 2.7~3.3 m²/m, which was at the leading level of the industry.
