SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims to provide a three-blade milling cutter flat tooth for aluminium, it has throws the arc cell type, and the rigidity and the chip removal that increase the inner wall are smooth and easy, and protect the end tooth, prevent to collapse a mouthful, more wear-resisting characteristics.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a three sword for aluminium milling cutter flat teeth, includes sword target and tool bit, the one end and the tool bit fixed connection of sword target, its characterized in that: the cutter head consists of a chip removal part and a cutting part, and the diameter range of the cutter head is 24.5mm-25.5 mm;
the chip removal part and the cutting part are distributed in an alternate annular array by taking the axis of the cutter target as an array center line.
Furthermore, the chip removal part consists of a main chip removal groove and an auxiliary chip removal groove, and one end of the main chip removal groove is communicated with the auxiliary chip removal groove;
through above-mentioned technical scheme, improve current chip groove, reduce the damage of piece to the tool bit.
Furthermore, the inner wall of the main chip groove is spiral, and the depth range of the main chip groove is 7.5mm-8.5 mm;
through above-mentioned technical scheme, the degree of depth of fixed chip groove increases the chip removal rate.
Furthermore, the depth range of the auxiliary chip groove is 6.5mm-7.5mm, and the inner wall of the auxiliary chip groove is the same as the inner wall of the main chip groove in spiral shape;
through above-mentioned technical scheme, supplementary chip groove can further make main chip groove chip removal more smooth and easy.
Furthermore, the cutting part consists of three cutters which are distributed in an annular array by taking the surface of one end of the cutter target as the center;
through above-mentioned technical scheme, three cutters are the distribution of spiral shape, more help and chip removal.
Furthermore, the center point of one of the cutters is crossed with the center point of the other two of the cutters in a spiral shape, and the side surface of each cutter in a spiral shape is the same as the spiral shape of the inner wall of the main chip groove;
through the technical scheme, the spiral shape of the cutter is the same as that of the inner wall of the main chip removal groove, so that chip removal is facilitated.
To sum up, the utility model discloses following beneficial effect has:
the cutter has the advantages that the chip removal part and the cutting part are distributed in an alternate annular array mode by taking the axis of the cutter target as an array center line, so that the rigidity of the inner wall of the auxiliary chip removal groove is increased, chip removal is smooth, end teeth of the cutter are protected, the phenomenon of opening breakage is avoided, and the cutter is more wear-resistant.
