Causes Of Quality Problems Of Worm Gear Grinding Machine Diamond Wheel
As the diamond roller forming dressing method with a short dressing time, can repair a variety of complex surface, surface accuracy to maintain good, easy to operate and other characteristics of the dressing, its use has gradually been recognized, in production has also been the more The more widely used. But in the wheel design, manufacture and use of such problems often occur, and that today we have to look at the quality of the worm wheel diamond wheel causes analysis:
1, first of all, the choice of diamond abrasive, in the grinding process, the abrasive is the main body, the wheel can be used CBN diamond wheel dressing dressing, followed by corundum abrasive, camshaft machining in such high-intensity grinding case , The use of CBN abrasive is the best choice. CBN abrasives of different grades have different crystal shapes and particle shapes, and they have different strength, thermal stability, resistance to chemical attack and crushing characteristics due to different manufacturing processes. The choice of grinding fluid type, pressure and flow rate must also be considered.
2, Secondly, the choice of concentration, the level of concentration that the grinding wheel in the face of the diamond grinding wheel per unit area to participate in the number of grinding, high concentration can bring high grinding ratio, 200% concentration ratio of 100 % Of the concentration of long life of 4 to 5 times. At present, high-speed, high-efficiency grinding are used in higher concentrations, such as imported grinding camshaft grinder matching concentrations are generally 200%.
