如切割在锯的金刚石工具的磨损机理以及锯切国内外{lx1}的研究和各种不同的角度进行审查的过程机制，时间锯石硬脆材料的金刚石工具。由于石材锯，如在锯截止目前，该机制的认识过程的复杂性硬而脆的材料，尚未统一，金刚石工具磨损机理以及锯切力的理论研究还需要深入。

介绍

是指具有高硬度，材料，通常不高脆性硬脆材料导电或半导体，如石材，玻璃，硅晶体，石英晶体，硬质合金，陶瓷等各类对。随着科学技术和现代工业的发展，硬脆材料的应用领域不断扩大，硬脆材料加工技术的发展也是在不断变化。在一个硬脆材料加工方法不同，切割占有重要地位。例如，在建筑板材和岩石材料精密零件加工，切割加工{dy}个加工过程，锯以上处理成本的50％的总处理费用。目前，硬而脆，如切割，主要是使用了金刚石刀具材料，各种石材。由于钻石是已知最硬的xx物质，其出色的表现，以确定切割等领域硬脆材料，石材其有着广阔的发展前景。

金刚石工具的应用锯切硬脆材料的加工方法是：切割圆锯片，金刚石带锯切割，钻石切割，如金刚石绳锯锯框架，切割。尽管每种方法都有自己不同的特点和适用范围，但其切割机理和金刚石磨损机理都大致相同。由于岩石切割钻石切割工具是最重要的目的，因此，深入研究石材锯切和金刚石刀具磨损机理的切削工具，金刚石生产机制和合理正确使用的重要性。长期以来，国内外专家和学者对金刚石工具锯切花岗岩的加工机理，金刚石工具磨损机理和锯锯切过程工程的试验和研究的很多，取得了明显成效，对岩石锯切加工研究和金刚石工具的发展起到了积极作用的理论指导。

钻石切割石材切割金刚石磨料

机制通常通过烧结或电镀金属箔刀具。刀具的金刚石的过程中，磨类似，但由于材料的影响，岩石，陶瓷等硬脆材料加工机理和不同金属处理机制，处理更加复杂。自{dy}个钻石切割石材切割，钻石切割，因此，石机制更使用的工具。国内外学者对锯切花岗石的长期研究处理机制，金刚石工具：从入侵压头早在岩石下使用的故障理论，单颗粒金刚石划伤表面形貌观察法的进步综合应用发展一个偏光显微镜和扫描电镜的岩石表面形貌，以及出现和裂纹扩展法，利用声发射信号的岩石切割地位评价。然而，由于岩石切割，如国家硬而脆的材料，切削过程是非常复杂的，它的切割机制尚未形成一个统一的认识。

研究类似磨，这是对单颗粒金刚石切割石材加工与最初的机制。早期的试验研究表明：根据在切割花岗岩，岩石损伤主要是脆性倒塌，主要是打破不同条件下的单颗粒金刚石，在同一时间，根据不同的矿物成分，岩石依然产生塑性变形。

Diamond abrasive cutting tools allow a menace

Diamond tools for cutting hard and brittle materials such as stone sawing at the time of the mechanism of the process of sawing the wear mechanism of diamond tools and sawing edge research at home and abroad and various perspectives are reviewed. Because stone sawing hard and brittle materials, such as the complexity of the process of sawing to date understanding of the mechanism is not yet uniform, wear mechanism of diamond tools and sawing force the theoretical study also need depth.

Introduction

are referring to hard and brittle materials with high hardness, high brittleness of the material, usually non-conductive or semiconductor, such as all kinds of stone, glass, silicon crystal, quartz crystal, hard alloys, ceramics and so on. With the development of science and technology and modern industrial development, hard and brittle materials expanding application areas, hard and brittle materials processing technology is also evolving. In a variety of hard and brittle material processing methods, cutting occupies an important position. For example, in architectural sheet metal and rock material precision parts machining, sawing processing are the first machining process, sawing the total processing costs of more than 50% of processing costs. At present, hard and brittle materials such as stone cutting mainly uses a variety of diamond cutting tools. Because diamond is the hardest known natural material, its outstanding performance to determine its in stone cutting hard and brittle materials, such as the field has broad prospects for development.

application of diamond tools for sawing hard and brittle materials processing methods are: cutting circular saw blades, diamond cutting band saw, diamond cutting saws framework, such as Diamond Wire Saw Cutting. Although each method has its own different characteristics and application scope, but its mechanism and diamond cutting wear mechanism are largely the same. As the rock cutting diamond cutting tools are the most important purposes, therefore, in-depth study the mechanism of stone sawing and diamond cutting tools wear mechanism of diamond cutting tools for manufacturing and the proper use of reasonable significance. A long time, domestic and foreign experts and scholars on the diamond tools for sawing granite processing mechanism, the wear mechanism of diamond tools and sawing the sawing process works a lot of trials and studies, and achieved remarkable results, on the rock sawing processing and research and development of diamond tools has played a positive role of theoretical guidance.

Diamond Cutting Stone Cutting Mechanism of diamond abrasive

usually through sintering or electroplating foil cutting tools. The process of diamond cutting tools, grinding is similar to, but because of material impact, rocks, ceramics and other hard and brittle materials processing mechanism and the mechanism of different metal processing, and processing more complex. Since the first diamond cutting tools used in stone cutting, diamond cutting and therefore the mechanism of stone more. Domestic and foreign scholars on diamond tools for sawing granite processing mechanism of long-term research: From the early use of invasive pressure head in the rock under the fault theory, single particle diamond scratched the surface morphology observation method to the comprehensive application of the progressive development of a polarizing microscope and SEM surface morphology of the rock, as well as the emergence and expansion of crack law, using acoustic emission signal evaluation of rock cutting status. However, due to rock cutting hard and brittle materials, such as state and cutting process is very complex, its mechanism of cutting has yet to form a unified understanding.

study with similar grinding, it is initially on the cutting processing of single stone diamond particles and between the mechanism. Early pilot study shows that: The single diamond particles under different conditions when cutting granite, rock damage mainly to brittle collapse mainly broken; At the same time, according to different mineral composition, rock still produce plastic deformation.
