Preparation and cutting properties research of diamond array pattern on saw blade

The application of diamond array pattern on saw blade was introduced,and the technology of realizing diamond array pattern on saw blade was described.Two kinds of conventional saw blades and one saw blade with diamond array pattern were used in the test to cut reinforced concrete.The experimental results indicated that under the same conditions(the same matrix,diamond grade and concentration),the cutting speed of diamond array patterned saw blade is increased by 23.6%,and its working life is prolonged by 31.5%.In addition,the cutting speed of diamond array patterned saw blade is prolonged by 18.8%,and the life is prolonged by 21.9%,compared with the conventional saw blade,of which the matrix is the same but the diamond concentration is 5% higher.Even with reduced diamond concentration,diamond array patterned saw blade can still improve the efficiency and life.This shows the superiority of saw blade with diamond array pattern.
