The levorotation single-edged cutter comprises a cutter body, a cutter handle is arranged at the rear end of the cutter body, a cutting part is arranged at the front end, a levorotation chip removal groove is formed in the cutting part and spirally extends to the front end of the cutting part to form a step-type end cutting edge, a side opening of the chip removable groove is a spiral cutting edge, the end cutting edge is composed of a first cutting edge body, a second cutting edge body and a third cutting edge body, the first cutting edge body and the third cutting edge body are inclined cutting edge bodies facing backwards, the second cutting edge body is parallel to the axis of the cutter body, the front end of the first cutting edge body is connected with the spiral cutting edge, a fourth cutting edge body inclining backwards is formed on the back face, at the connecting position, of the spiral cutting edge, the front end of the first cutting edge body and the front end of the fourth cutting edge body are connected to form a cutter point, a rear cutter face of the spiral cutting edge is provided with a spiral threaded groove, the groove face and the back face of the chip removable groove are provided with spiral lines respectively, and therefore it is ensured that machined workpieces are high in accuracy, free of burrs and high in finish degree. Edge breakage of notches of the machine workpieces is avoided, the levorotation single-edged cutter can further be used for machining special-shaped grooves or holes without changing the cutter, and the machining efficiency is improved.

Description

Left-handed single cutting tool
Technical field
The present invention relates to metal cutting tool technical field, be specifically related to left-handed single cutting tool.
Background technology
In the time of the precision component of some composite materials of machining, because the design deficiency of existing cutter makes in process, because the characteristic of composite is that scrap is not easy timely discharge, on cutting face, easily produce burr, can not meet the requirement of processing, the surface quality of workpiece can not be guaranteed, now a lot of manufacturers first process basic shape by roughing, and then fine finishining, finally pass through manual grinding, such operation production efficiency is low, production cost is high, shortcoming is obvious, and to special-shaped gully, the existing cutter of part in hole is difficult to processing, need repeatedly tool changing to be difficult to ensure the precision of processing.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, and left-handed single cutting tool is provided, and ensures that workpiece to be machined has higher precision, without burr, highly polished, avoid the phenomenons such as workpiece otch spring limit, can also be used to working special-shaped gully or hole without tool changing, improve working (machining) efficiency.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Left-handed single cutting tool, comprise cutter hub, described cutter hub rear end is handle of a knife, front end be cutting portion, cutting portion is provided with left-handed bit-withdrawing slot, bit-withdrawing slot is spirally extended to the end sword of cutting portion front end formation stepped ramp type, the limit mouth of bit-withdrawing slot is helical edges, described end sword is by the first sword, the second sword, the 3rd sword forms, the first sword, the 3rd sword is inclination sword backward, the second sword and cutter hub axis parallel, the first sword front end and helical edges are joined, the helical edges back side of joint forms sweptback the 4th sword, the first sword and the 4th sword front end formation point of a knife that joins, the rear knife face of described helical edges is provided with spiral groove, spiral groove makes the suitable relief angle of the formation of helical edges, strengthen the toughness of helical edges, make helical edges be difficult for crumbling, bit-withdrawing slot groove face and the back side are equipped with spiral lines, bit-withdrawing slot spiral lines terminates in end sword place, avoid holding tooth shape to become the destruction of teeth shape, make to hold sword to keep integrality.Each cutting edge of end sword all can cut separately also and can cut simultaneously, makes to hold the concrete cutting edge of sword to carry out the processing in special-shaped gully, hole according to the shape adjustments cutter hub that will process.
Preferably, described cutter hub diameter is 6mm, the 4th tread degree d is 0.21mm, the 4th sword port is 2.8mm to the first sword port width a, the width b of the second sword is 3.1mm, the horizontal sextant angle α of described the first sword and cutter hub axial line is 77 °, the horizontal sextant angle β of described the 3rd sword and cutter hub axial line is 45 °, the horizontal sextant angle γ of described the 4th sword and cutter hub axial line is 55 °, the size routine of cutter hub, palette knife head end cutting edge can be processed less hole or special-shaped gully, the first sword and the 4th sword front end join and form point of a knife the effect of the centering location in longitudinal when incision is provided, described spiral groove is synchronizeed with helical edges spiral, and be arranged on helical edges cutting edge place.Spiral groove contributes to chip removal, is no matter longitudinally incision or laterally incision, all the play the guiding role smear metal of having nothing to do of cutting is discharged smoothly, and left-handed spiral can not produce otch and collapse limit.
Further, described bit-withdrawing slot groove face spiral lines spiral is synchronizeed with bit-withdrawing slot spiral, bit-withdrawing slot back side spiral lines is synchronizeed with helical edges spiral, spiral is synchronously more conducive to the timely discharge of smear metal, the spiral lines at the back side impels smear metal to send in the time of horizontal incision, the chip discharge when spiral groove that bit-withdrawing slot engages its groove face impels longitudinal incision.
The invention has the beneficial effects as follows: adopt such scheme, left-handed lower chip removal makes to cut smooth discharge, workpiece otch is smooth carefully and neatly done, and precision is high, and otch is difficult for collapsing limit, utilizes end sword can carry out not tool changing processing to special-shaped gully, hole with helical edges, raises the efficiency.
Brief description of the drawings
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged drawing of I portion in Fig. 1.
Wherein: 1 is cutter hub, 2 is bit-withdrawing slot, and 3 is end sword, and 3.1 is the first sword, and 3.2 is the second sword, and 3.3 is the 3rd sword, and 3.4 is the 4th sword, and 4 is helical edges, and 5 is spiral lines, and 6 is spiral groove.
