Research On Cutting Properties Of Diamond Saw Blades And Falling Dust Design Of Cutter

Diamond saw blades are one of the most extensively used tools in industries, such as rock processing and architecture. Aiming at problems of cutting efficiency, life-span, dust of saw blade, there are two factors which influence cutting capacity and life-span of diamond saw blade. One is whether or not matrix material can bind diamond grains together and show good cutting properties, and the other is whether or not matrix materials can be abrasive suitably, guaranteeing the blade of diamond saw blade came out. Therefore, improvement of binding properties of matrix materials is one researching direction of importance. In cutting procedure, dust of rock not only does harm to the operator, but also pollutes ambient environment.On the basis of original saw blade, add tungsten carbide, cobalt and thulium Cerium, do contrast test and analytical research for cutting properties of new saw blades; and add some elements to improve properties of matrix materials for improving matrix materials' hardness, hold force to diamonds and wear-resistance properties; and do some modification in design of cutting section for reducing dust and environmental pollution.This paper combines a lot of theories and tests, develops a high-efficient, long-life span and low-cost Cu-Fe based diamond saw blade, and do several aspects of research and experiment as following: 1. Checking affective factors of cutting capacity and failure discipline of diamond, analyze effect of cutting property in their corresponding phases.2. Carrying out granite sawing experiment, measure cutting volume and wear capacity, and investigate working surface morphology and different prescriptions those influence diamond edge came out, segments surface morphology and life of saw blades by PE, SEM and Sclerometer. The result shows that fit amount of tungsten carbide, cobalt and rear earth Cerium increases hardness, hold force to diamonds, protrusion properties and density of matrix materials, while refines granularity of knot.3. Researching cutting framework and design falling-dust framework for cutter's cutting part, in order to reduce dust and harm to workers.
