The method directly uses a finish milling cutter to carry out reverse milling and roughing and then carries out forward milling and finishing, and has the defects of short service life and high cost of the cutter.
SUMMERY OF THE UTILITY MODEL
Therefore, the utility model provides the staggered-tooth rough-finish integrated milling cutter for solving the problems, which can finish two procedures of rough machining and finish machining simultaneously in one-time milling, greatly improves the efficiency and prolongs the service life of the cutter.
In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a rough and fine integrated milling cutter of staggered teeth, includes the cutter body, crisscross finish machining sword and the rough cutting edge of opening that is equipped with on the cutter body, finish machining sword carries out the spiral with the rough cutting edge of opening and extends along the axial of cutter body, and is adjacent finish machining sword is formed with spiral helicine chip groove between the rough cutting edge with opening, the cutter body tip corresponds finish machining sword department and is equipped with first end sword, the cutter body tip corresponds and opens rough cutting edge department and is equipped with the second end sword, the helical angle of finish machining sword is less than the helical angle of opening rough cutting edge, the anterior angle of first end sword is less than the anterior angle of second end sword.
The cutter body is further improved, and a fine machining blade and a rough machining blade are respectively arranged on the cutter body.
The improved structure is characterized in that the cutter body is respectively provided with two fine machining blades and two rough machining blades.
In a further improvement, the height of the finishing edge is H1, and the height of the roughing edge is H2, so that H1> H2.
Further improved, the helix angle of the finishing cutting edge is 0-20 degrees.
Further improved, the spiral angle of the roughing edge is 21-45 degrees.
In a further improvement, the rake angle of the first end edge is 13-30 °.
In a further improvement, the rake angle of the second end edge is-5 to 8 degrees.
Through the technical scheme provided by the utility model, the method has the following beneficial effects: the milling cutter has the advantages that the rough cutting tool and the finish machining milling cutter are integrated on one cutter, so that the milling cutter has the function of rough machining and the finish machining capacity, the purpose of milling a workpiece can be achieved by only adopting the milling cutter to carry out one-time feeding during machining, the surface roughness meeting the product requirement is machined, the time for replacing the milling cutter in the traditional machining mode is saved, the production efficiency is improved, and the service life of the cutter is prolonged.
