When it comes to CNC forming grinding wheel gear grinding machine, I believe many people have heard of it, because it is widely used, and it is used in wind power, military industry, etc., and it plays a very important role. Today, Xiaobian will share with you the knowledge of CNC forming grinding wheel gear grinding machine.
The CNC forming grinding wheel gear grinding machine adopts the forming method for grinding, and the truncation accuracy of the grinding wheel is the key, which depends on the truncation calculation accuracy and the dressing accuracy of the grinding wheel. Gear grinding machine manufacturers at home and abroad have conducted in-depth research on the dressing technology of forming grinding wheels and developed different grinding wheel dressing devices to ensure the dressing accuracy of the grinding wheel and improve the gear grinding accuracy.
The dressing of the forming grinding wheel mainly includes the diamond pen and the diamond roller. The diamond pen dressing has a simple structure and low cost, and theoretically higher dressing accuracy can be obtained. Due to the serious wear and tear of the diamond pen, the short life span, and the amount of wear is difficult to estimate and cannot be fully compensated, resulting in poor consistency of sand profile accuracy, which has a greater impact on the grinding of large gears, and is gradually replaced by diamond roller dressing. The diamond roller has high rigidity, large dressing amount and high efficiency, and adopts the trajectory envelope method, which is more suitable for dressing complex forming surfaces. The method of diamond roller dressing grinding wheel is divided into plunge roller dressing and swing roller dressing.
During the grinding process, the grinding wheel wears and becomes dull, and the grinding wheel needs to be dressed to produce a new sharp profile while maintaining consistent accuracy. The grinding wheel dressing tool and dressing conditions have a significant impact on the grinding wheel dressing quality, which directly determines the grinding wheel shape and profile accuracy. The sharpness of the dressing determines the grinding force and grinding temperature. It is necessary to select reasonable grinding wheel dressing parameters.
Choose a reasonable dressing speed ratio qd to dress the grinding wheel. When the dressing speed ratio qd is small, the relative speed of the diamond roller and the grinding wheel is high, the impact force is large, the abrasive grains of the grinding wheel are broken more, and the resulting cutting edge is sharper, but the overall profile accuracy of the grinding wheel is slightly worse, which is suitable for rough grinding. Large grinding allowance; when the dressing speed ratio qd is large, the relative speed of the diamond roller and the grinding wheel is small; the interaction force is mainly the extrusion force, after the abrasive grains of the grinding wheel are extruded, the sharp corners are broken, forming more The micro-edge of the grinding wheel has high overall profile accuracy and is suitable for fine grinding. Through a lot of experimental research and production practice, it can be known that when dressing the grinding wheel, the linear speed ratio of the diamond roller and the grinding wheel is taken as 0.3-0.8, the small value is taken for rough grinding, and the large value is taken for fine grinding.
The dressing depth affects the force characteristics of the abrasive grains of the grinding wheel. When the dressing depth is small, the damage strength of the grinding wheel abrasive grains is small, resulting in micro-breaking and forming micro-edges. The profile accuracy is high and suitable for fine grinding; when the dressing depth is large, grinding The grains are broken and broken by force, and part of the binder falls off, forming a sharp cutting edge and a chip space, which is suitable for rough grinding. The selection of dressing depth should consider the size of the abrasive grains of the grinding wheel, so as to avoid excessive dressing amount that will cause the abrasive to fall off as a whole, which will waste the abrasive and make it difficult to form a perfect profile.
The CNC profile grinding wheel is becoming more and more popular these days, not only because of its practicality, but also because of its technology.
