Wherein: 1. a plane; 2. a bevel; 3. a flank face; 4. a rake face; 5. a tool body; 6. a cutting edge.
Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1, 2 and 3, the milling cutter structure of the present embodiment includes a cutter body 5, the cutter body 5 is a cylindrical structure, the head of the cutter body 5 is provided with a double-tooth structure, the double-tooth structure is symmetrical and oppositely arranged along the central plane of the cutter body 5, and the two single-side tooth structures are the same;
the single-side tooth-shaped structure is as follows: including inclined plane 2, inclined plane 2 is low right height on a left side, and the head extension on inclined plane 2 has the back knife face 3, and one side of inclined plane 2 is cut there is the notch, and the notch upper surface is plane 1, and the head extension of plane 1 has the rake face 4.
The notch is a chip groove.
The notch is a straight groove.
The included angle a between the rake face 4 and the horizontal plane is 5-30 degrees.
The included angle b between the rear cutter face 3 and the vertical plane is 5-20 degrees.
The rake face 4 and the flank face 3 of the single-sided tooth structure intersect to form a cutting edge 6.
The cutting edge 6 is in a convex and concave arc shape.
The double-tooth structure of the head part of the cutter body 5 is characterized in that two symmetrical convex concave arc-shaped cutting edges 6 are intersected in the center of the head part of the cutter body 5.
The tool body 5 is made of hard alloy.
The surface of the tool body 5 is coated with a diamond coating.
In the actual preparation process of the cutter, a grinding hard alloy bar is used for forming, the consistency of the double-tooth structure is guaranteed, diamond coatings are coated on the front cutter face 4 and the rear cutter face 3 of the cutter body 5 after machining and forming, the prepared cutter can be installed in a milling machine, and materials with high machining hardness and strength can be machined.
The anterior angle in every unilateral profile of tooth structure be the burden, the relief angle is positive.
Supplementary explanation:
the reference plane of the rake angle is a horizontal plane, and generally the rake angle is downwardly inclined, being a positive rake angle, and if the rake angle is upwardly inclined, being a negative rake angle.
The reference plane of the clearance angle is a vertical plane, if the flank face 3 inclines to the right or inwards, the clearance angle is a positive clearance angle, and if the flank face 3 inclines to the left or outwards, the clearance angle is a negative clearance angle. If the clearance angle is a negative clearance angle, the flank face 3 hits the cut face of the workpiece during cutting, so that the clearance angle cannot be negative and is positive. The rake angle has a positive rake angle and also has a negative rake angle.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
