Abstract

Frez zgrubno-wykańczający charakteryzuje się tym, że ma co najmniej cztery rowki wiórowe (4) o radełkowanej powierzchni (5) oraz co najmniej cztery bezfazowe ostrza skrawające na powierzchni obwodowej, których płaszczyzna przyłożenia (6) obniżona jest o 0,01-0,02 mm względem radełkowanej powierzchni (5) oraz posiada przesunięcie płaszczyzny przyłożenia (6) względem rowków wiórowych (4). Geometria bezfazowego ostrza skrawającego ma skręt spirali rowka wiórowego (4) o kąt 30° - 38°, a kąt natarcia wynosi 7° - 16°, kąt przyłożenia wynosi 8° - 16°, natomiast kąt pomocniczej płaszczyzny przyłożenia (7) wynosi 16° - 30°, zaś promieniowy kąt przyłożenia (8) powierzchni radełkowanej (5) wynosi 6° - 12°.The roughing-finishing milling cutter is characterized in that it has at least four chip flutes (4) with a knurled surface (5) and at least four chamfer-free cutting blades on the peripheral surface, the clearance plane (6) of which is lowered by 0.01-0.02 mm relative to the knurled surface (5) and has an offset of the clearance plane (6) relative to the chip flutes (4). The geometry of the chamfer-free cutting blade has a helical twist of the chip flute (4) by an angle of 30° - 38°, a rake angle of 7° - 16°, a relief angle of 8° - 16°, while the angle of the auxiliary clearance plane (7) is 16° - 30°, and the radial clearance angle (8) of the knurled surface (5) is 6° - 12°.
