Diamond Blades Life And Machinability

Diamond Blades life and machinability
   Diamond Blades Diamond Blades life expectancy (formerly known as Diamond Blades Durability), blade manufacturer Mid-range blade production Diamond Blades life penalty generally used Diamond Blades wear A predetermined value can also be used as a criterion for the occurrence of a phenomenon, such as vibration intensification, deterioration of the surface roughness, chip breakage and chipping. After reaching Diamond Blades life, Diamond Blades should be ground, turned or discarded. Diamond Blades The life of the Diamond Blades before the waste is called the Diamond Blades total life. Production is often based on the processing conditions according to the minimum production costs or the highest productivity principle, to determine the Diamond Blades life and the proposed working hours quota.
Refers to the ease with which a part is machined into a qualified product. It is based on the specific processing object and requirements, available Diamond Blades life of the length of the surface quality of the processing of good or bad, the level of metal removal rate, the size of the cutting power and the difficulty of chip breaking as a criterion. In production and experimental studies, it is often used as a measure of the machinability of a material, which means that when the Diamond Blades have a life span of several minutes, the cutting speed allowed by the material is cut. The higher the workability, the better, generally take 60,30,20 or 10 minutes.
 Diamond Blades wear at the time of cutting is a combination of heat and mechanical friction produced by the physical and chemical effects of the combined results. Diamond Blades wears wear bands, gaps, and cuts on the back of Diamond Blades, the crescent-like wear on the front, and the occasional oxidizing pits and groove wear. When these wears extend to a certain extent, it causes Diamond Blades to fail and can not be used. Diamond Blades Gradually wear factors, usually abrasive wear, adhesive wear, diffusion wear, oxidation wear, hot cracking wear and plastic deformation. Under different cutting conditions, especially at different cutting speeds, Diamond Blades is affected by one or more of the above-mentioned wear mechanisms. For example, at lower cutting speeds, Diamond Blades are generally damaged by abrasive wear or adhesive wear; at higher speeds, diffusion wear, oxidation wear and plastic deformation are prone.
Diamond Blades The temperature of the cutting zone is different throughout the cutting process to form a temperature field chip and the temperature distribution of the workpiece. This temperature field affects the chip deformation, the size of the chip, the surface quality, the machining accuracy and the wear of Diamond Blades Etc., but also affect the cutting speed. In general, the cutting area of the metal after the shear deformation after the chip, followed by further sharp friction with the front of the tool, so the temperature field temperature distribution is not the highest point in the highest pressure at the edge, but in front On the edge of a distance from the edge of the place. The temperature distribution of the cutting area shall be measured by artificial thermocouple method or infrared temperature measurement method. The temperature measured by the natural thermocouple method is only the average temperature of the cutting zone.
 Diamond Blades During the cutting process, Diamond Blades and the workpiece often produce free vibration, forced vibration or self-excited vibration (flutter) and other types of mechanical vibration. Free vibration is caused by some sudden impact of machine tool parts, it will gradually decay. Forced vibrations are caused by continuous intertwined disturbances (eg, unbalanced machine tools, intermittent cuts, etc.) that are generated inside or outside the machine, and its effect on cutting depends on the magnitude of the interference force and its frequency. Self-excited vibration is caused by the sudden interference between Diamond Blades and the workpiece (such as the hard spot encountered in the cutting) caused by the initial vibration, so that Diamond Blades rake angle, angle and cutting speed changes, and produce vibration coupling , And from the steady-state energy sources to obtain periodic effects of energy, promote and maintain vibration. In general, a variety of native self-excited vibrations may occur depending on the cutting conditions, and the vibration pattern left on the machined surface will produce a more common regenerative self-excited vibration. Each of these vibrations usually affects the quality of the knife surface, reduces the life of the machine and Diamond Blades, reduces productivity, and causes noise, which is extremely harmful and must be managed to eliminate or mitigate.
