Description
Technical field
The utility model relates to the cutting-tool engineering field of machining, is 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, common slotting cutter is used 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.
Utility model content
Technical problem to be solved in the utility model 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 fiberglass particle contact area is large, vibrate little, not easily produce burr cutting face precision good, and do not destroy the structure of glass fibre.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
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, is spiral bit-withdrawing slot between twice spiral cutting sword.Left-handed combination with dextrorotation makes the cutting face of cutting portion more complete, increases the contact area with glass fibre during cutting, reduces vibration and mutual impact, avoids making the excessive destruction of causing glass fibre structure of local cutting force.
Described twice spiral cutting sword crosses in cutting portion front end and forms cutting end sword, and intersection caves inward.
Described cutting portion external diameter is identical with handle of a knife.The convenient size distinguishing cutter.
Described cross one another back of the body cutting edge forms rhombus lines, rhombus lines is fine and close, even, can better balanced cutting power, fully contact with glass fibre when cutting, avoid the excessive destruction of causing glass fibre structure of the amount of feeding once, the amount of feeding is little, cuts the generation more thoroughly reducing 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 ensure milling cutter cutting edge when cutting and glass fibre keep maximum Exposure, refinement balanced cutting power, prevent the excessive destruction of causing glass fibre structure of the amount of feeding.
The beneficial effects of the utility model are: adopt such scheme, can ensure that the structure of glass fibre is not destroyed, reducing the generation of burr simultaneously when cutting, and improve the precision in cutting face, make the glass fibre after processing meet instructions for use.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the utility model will become apparent.
Fig. 1 is structural representation of the present utility model.
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 is fine and close, even, be spiral bit-withdrawing slot 4 between twice spiral cutting sword, distance between spiral bit-withdrawing slot 4 is between 1-2mm, twice spiral cutting sword crosses in cutting portion front end and forms cutting end sword, and intersection caves inward.
The utility model is not limited to described embodiment; those skilled in the art is not departing from spirit of the present utility model namely openly in scope; still can do some revise or change, therefore the scope that rights protection scope of the present utility model limits with claims is as the criterion.
Claims (5)
