Abstract
The invention discloses an end mill special for a single-edge forming 'V'-shaped groove, which comprises a handle and a body. The body comprises a first cutting edge, a second cutting edge, chip grooves and spiral grooves and is characterized in that the first cutting edge is dissymmetrical with the second cutting edge, cutting edge angle of the first cutting edge lambda s is 15 degree to 45 degree, the cutting edge angle of the second cutting edge is smaller than that of the first cutting edge in a range of 2 degree to 6 degree, the front angle gamma 0 of the first cutting edge and the second cutting edge is 5 degree to 10 degree, the rear angle alpha 0 of the first cutting edge and the second cutting edge is 12 degree to 15 degree, spiral angle of each spiral groove is 30 degree, and the two chip grooves are disposed on spiral grooves close to the first cutting edge and the second cutting edge respectively. The end mill has sharp cutting edge, is smooth in chipping, low in cutting resistance, and tipping and broken cutter can be avoided. The machined 'V'-shaped groove is symmetrical, fine in surface quality, and high-efficient, high-quality and high-precision milling of the 'V'-shaped groove are realized.
Description
Technical field
The present invention relates to a kind of slotting cutter, be applicable to the processing of " V " type groove, belong to the cutter manufacturing technology field of mechanical processing industry.
Background technology
Milling Process is a kind of processing method commonly used in the machining, and slotting cutter is the most frequently used milling cutter.Can only be one of difficult point of Milling Process with " V " type groove of slotting cutter processing.Two sword symmetrical structures, the cutting blade angle λ of two cutting edges on the slotting cutter are adopted in the slotting cutter cutting edge design of general processing " V " type groove usually
sBe identical, two cutting edges are worked simultaneously in process, and cutting resistance is bigger, occurs tipping, breaking easily, and processed " V " type notch is prone to produce flange, burr.
Summary of the invention
The objective of the invention is to the deficiency to prior art, provide a kind of working (machining) efficiency single-blade moulding " V " type groove high, that be difficult for tipping, breaking special-purpose slotting cutter, " V " type groove of this slotting cutter processing is symmetrical, surface quality is good.
The present invention adopts following technical scheme to realize for the technical problem that solves:
The special-purpose slotting cutter of single-blade moulding of the present invention " V " type groove; Comprise: handle of a knife and cutter hub; Said cutter hub is made up of first cutting edge, second cutting edge, groove for cuttings and helicla flute; Be characterized in: first cutting edge and second cutting edge are designed to two sword dissymmetrical structures, the cutting blade angle λ of said first cutting edge
sBe 15 °～45 °, the cutting blade angle of second cutting edge is less than the cutting blade angle of first cutting edge, and difference is 2 °～6 °, the anterior angle γ of first cutting edge and second cutting edge
0Be 5 °～10 °, relief angle α
0Be 12 °～15 °, the spiral fluted helixangle is 30 °.
Described groove for cuttings has two, is separately positioned on the helicla flute near first cutting edge and second cutting edge.
Compared with present technology, the effect that the present invention is useful is embodied in:
1, the present invention adopts two sword dissymmetrical structures, and the cutting edge that plays the final molding effect only has one, adds man-hour first cutting edge and plays the cutting forming effect; The cutting blade angle of second cutting edge is less than the cutting blade angle of first cutting edge, and difference is 2 °～6 °, and the second cutting edge work in-process plays the assisted machining effect; " V " type groove symmetry of being processed is good.
2, among the present invention because the anterior angle γ of first cutting edge and second cutting edge
0Be 5 °～10 °, relief angle α
0Be 12 °～15 °, make that cutting edge is sharp, cutting resistance is little, between main cutting edge and helicla flute, be provided with groove for cuttings simultaneously, make chip removal smooth and easy, significantly reduced tipping, breaking phenomenon generation.
3, among the present invention because the cutting blade angle λ of first cutting edge
sBe 15 °～45 °, machinable " V " type groove scope is wide, and " V " type groove angle angle is 30 °～90 °.

The specific embodiment
Embodiment 1:
As shown in Figure 1, present embodiment is the special-purpose slotting cutter of a kind of single-blade moulding " V " type groove, and processing " V " type groove 7 angle angles are 30 ° on workpiece 8.The special-purpose slotting cutter of this single-blade moulding " V " type groove; Comprise: handle of a knife 1 and cutter hub 2; Cutter hub 2 is made up of first cutting edge 6, second cutting edge 5, groove for cuttings 4 and helicla flute 3; Be characterized in: first cutting edge 6 and second cutting edge 5 are designed to two sword dissymmetrical structures, the cutting blade angle λ of first cutting edge
sBe 15 °, the cutting blade angle of second cutting edge 5 is less than the cutting blade angle of first cutting edge 6, and difference is 2 °, the anterior angle γ of first cutting edge 6 and second cutting edge 5
0Be 5 °, relief angle α
0Be 12 °, the spiral fluted helixangle is 30 °.
In the present embodiment, groove for cuttings 4 has two, is separately positioned on the helicla flute 3 near first cutting edge 6 and second cutting edge 5.
During work, the milling cutter rotation, lathe is done at the uniform velocity feed motion simultaneously, and second cutting edge 5 and first cutting edge 6 cutting workpiece 8, the second cutting edges 5 successively play the assisted machining effect, and first cutting edge 6 plays last moulding effect to " V " type groove.Therefore " V " type groove of being processed is symmetry fully; First cutting edge 6 and second cutting edge, 5 angle with rational parameters have improved stock-removing efficiency, have reduced cutting resistance, have prevented processed " V " type notch flange, the generation of burr effectively, groove for cuttings 4 is set is beneficial to chip removal; Therefore the present invention can realize efficient, high-quality, the high accuracy milling of " V " type groove.
Embodiment 2:
The difference of present embodiment and embodiment 1 is: processing " V " type groove 7 angle angles are 90 °, the cutting blade angle λ of first cutting edge
sBe 45 °, the cutting blade angle of second cutting edge 5 is less than the cutting blade angle of first cutting edge 6, and difference is 6 °, the anterior angle γ of first cutting edge 6 and second cutting edge 5
0Be 10 °, relief angle α
0It is 15 °.
