Abstract
The invention relates to the technical field of a cutter for cutting machining, in particular to a double-helix two-edge end mill. The double-helix two-edge end mill comprises a cutter handle and a cutting part which is arranged on the front end of the cutter handle and is characterized in that the cutting part is provided with a left-handed helix cutting edge and a right-handed helix cutting edge, the back surfaces of the cutting edges are provided with intersected back cutting edges, and a helix chip removal slot is formed between the two helix cutting edges. The cutting edges are refined to the intersected edges according to the characteristic that glass fibers are not wearable, the contact area between the cutting edges and the glass fibers is large when in processing, the vibration is small, burrs are unlikely to produce, the precision of a cut surface is good, and the structure of the glass fibers is not damaged.
Description
Technical field
The present invention relates to the cutting-tool engineering field that machining is used, be specifically related to double helix two-edged slotting cutter.
Background technology
Glass fibre is often used in industry, want obtain in requisition for shape need to carry out machining to glass fibre, but because glass fibre has the advantages that mechanical strength is high, property is crisp, use common slotting cutter to carry out the burr in machining cutting face many, surface accuracy is poor, be difficult to reach instructions for use, and easily cause the damage of glass fibre structure.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, double helix two-edged slotting cutter is provided, this milling cutter is for the not wear-resisting feature of glass fibre, cutting edge is refined into staggered sword, adding man-hour and glass fibre contact area is large, vibrate littlely, be difficult for producing burr cutting face precision good, and do not destroy the structure of glass fibre.
The technical solution adopted for the present invention to solve the technical problems is as follows:
Double helix two-edged slotting cutter, comprise the cutting portion of handle of a knife, handle of a knife front end, described cutting portion is provided with twice spiral cutting sword, and twice spiral cutting sword is respectively left-handed and dextrorotation, the back side of two cutting edges is provided with cross one another back of the body cutting edge, between twice spiral cutting sword, is spiral bit-withdrawing slot.Left-handed combination with dextrorotation makes the cutting face of cutting portion more complete, and the contact area of increase and glass fibre when cutting reduces to vibrate and mutual impact, avoids making the excessive destruction of causing glass fibre structure of local cutting force.
Described twice spiral cutting sword crosses and forms cutting end sword at cutting portion front end, and intersection caves inward.
Described cutting portion external diameter is identical with handle of a knife.The convenient size of distinguishing cutter.
Described cross one another back of the body cutting edge forms rhombus lines, rhombus lines densification, even, better balanced cutting power, in the time of cutting, fully contact with glass fibre, avoid the excessive destruction of causing glass fibre structure of the amount of feeding once, the amount of feeding is little, and cutting more thoroughly reduces the generation of burr, makes cutting face precision high.
Distance between described twice spiral bit-withdrawing slot is between 1-2mm.Between this distance, chip removal is smooth and easy, and ensures milling cutter cutting edge in the time of cutting and glass fibre keeps maximum Exposure, and refinement balanced cutting power, prevents the excessive destruction of causing glass fibre structure of the amount of feeding.
The invention has the beneficial effects as follows: adopt such scheme, in the time of cutting, can ensure that the structure of glass fibre is not destroyed, reduce the generation of burr simultaneously, improve the precision in cutting face, make the glass fibre after processing meet instructions for use.
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.
Wherein: 1 is handle of a knife, 2 is cutting portion, and 3 is back of the body cutting edge, and 4 is spiral bit-withdrawing slot.
Detailed description of the invention
Double helix two-edged slotting cutter as shown in Figure 1, comprise the cutting portion 2 of handle of a knife 1, handle of a knife front end, cutting portion is provided with twice spiral cutting sword, twice spiral cutting sword is respectively left-handed and dextrorotation, the back side of two cutting edges is provided with cross one another back of the body cutting edge 3, cross one another back of the body cutting edge 3 forms rhombus lines, rhombus lines densification, even, between twice spiral cutting sword, it is spiral bit-withdrawing slot 4, distance between spiral bit-withdrawing slot 4 is between 1-2mm, twice spiral cutting sword crosses and forms cutting end sword at cutting portion front end, and intersection caves inward.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
Claims (5)
