At first, set the grinding wheel inclination as the second clearance angle (normally from 0°to 18°), and turn the rotary table at a proper position so that the left cutting edge parallel to the X-axis of the hairline on the video displayer. That is the cutting edge parallel to the grinding wheel end face. Turn the fast feed handwheel to move the tool immediately in front of the grinding wheel end face, and then feed forward with figures screwing the micro feed wheel. The grinding wheel is removing the PCD&Materiale CBN fino a quando non ti fermi. Provatelo una o più volte fino a quando il nuovo tagliente non appare. Fare lo stesso al secondo tagliente.
In secondo luogo, centrare di nuovo le descrizioni girando le due ruote sul tavolo da lavoro trasversale. Guidare la mola rapidamente in avanti fino al PCD&Anche CBNl is near to the grinding wheel, and then feed ahead while swinging the rotary table. Radius cutting tip is forming gradually. As soon as the radius cutting edge coincides with the two linear cutting edges stop the feeding. Finally, set the grinding wheel inclination as the first clearance angle (normally from 5 ° to 8 ° ), do the same to the tools so that a very narrow flat (roughly 0.02mm thickness) comes into being on the cutting edge. The way described above is a normal method, and a special and more reasonable method is highly encouraged and reported to Demina precision. Special fixture design and even emendation to the machine will be considered by Demina as innovation.
