Abstract
The following conclusion is drawn from detailed mechanical analysis of Diamond Saw Blade,The load on diamond is not significant in cutting. However, at the moment the blade starts in its working state, the impact on rock has significant destructiveness on diamonds. Higher linear velocity of the blade, higher rock hardness and higher feeding speed all contribute in greater impact force on the diamond from the rock. And it is also stated that the unstable quality of diamond saw blade is closely related to the selection of diamond without following the TT1 test result. When designing the diamond saw blade, the saw cutting performance of the rock should be taken into consideration, as well as the necessary analysis of the force on the blade.There are three forces exerted on the saw blade: ①vertical downward pressure;②horizontal feeding thrust;③tangential cutting force of the saw. They are discussed separately in the following.
