In above-mentioned, the quantity of described end tooth blade 23 is four, the angle angle phase of the end tooth blade 23 described in four
Deng.
Further, described triangle cutting edge 211 is 25-40 degree with the angle [alpha] of triangle chip area 212, passes through
Triangle cutting edge 211 and the angle of triangle chip area 212, the periodic vibration producing during suppression cutting, deviation 2-3 °
This utility model slotting cutter can use in machine tool and Digit Control Machine Tool, with common slotting cutter occupation mode phase
With, the results showed, this utility model slotting cutter disclosure satisfy that the cutting of large inflow requires, and working angles are steady, Er Qieneng
Ensure the dimensional accuracy of work piece.
In sum, multiple tooth solid carbide thread milling cutter of the present utility model, periphery cutting edge upper surface is provided with multiple
Triangle chip area all between the triangle cutting edge of decile and two neighboring triangle cutting edge, can be in machining
