Description

It is a kind of for processing the whole hard alloy single-blade milling cutter of light-alloy

Technical field

The utility model belongs to the technical field of metal cutting process, and in particular to a kind of for processing the entirety of light-alloy Hard alloy single-blade milling cutter.

Background technique

At present in industries such as electronics, medical instrument, household electrical appliance, used aluminum alloy materials are relatively broad, as 3C is produced Product shell is usually required that with preferable appearance surfaces quality, with the preferable sense organ of acquisition, sense of touch etc., common bite There is the difference of cutting level in tool, cutter chatter frequency is higher, and workpiece surface is also easy to produce chatter mark, influences to be added in process The surface quality of chemical product.

This item product patent effectively solves the demand that such part most seeks high surface quality in process.

Utility model content

For overcome the deficiencies in the prior art, the purpose of the utility model is to provide a kind of for processing the whole of light-alloy Body hard alloy single-blade milling cutter.

The technical solution of the utility model is achieved in that

The utility model embodiment provides a kind of for processing the whole hard alloy single-blade milling cutter of light-alloy, including knife Handle and spiral helicine cutting portion positioned at the knife handle front end, the side of the cutting portion are spiral main cutting edge, the spiral shell The part that rotation main cutting edge extends to end face is the negative cutting edge in end face, and the hollow parts of the spiral helicine cutting portion are dust lead Slot.

Preferably, the helical angle of the spiral main cutting edge is 25 °, and all edge clearance angles of the spiral main cutting edge are 12 °, Rake angle is 20 °.

Preferably, the flank width of the spiral main cutting edge is 1.2mm, and flank step carries on the back a height of 0.9mm.

Preferably, the end clearance angle of the negative cutting edge in the end face is 5 °, and sideshake is 4 °.

Preferably, the slot bottom of the dregs guiding groove is fillet.

Preferably, the groove angle of the dregs guiding groove is 60 °~90 °, and the radius of slot bottom fillet is R4~R6mm.

Preferably, the dregs guiding groove is handled using mirror grinding.

Compared with prior art, the utility model has the beneficial effects that when solving processing light-alloy components, it is desirable that tool There is the problem of higher surface quality, universal cutter is unable to satisfy such processing request.The processing light-alloy is closed with whole hard The innovation of golden single-blade milling cutter, breaches key technology, and solving certain light alloy material parts processing surfaces is mirror surface requirement Process problem.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

The utility model embodiment provide it is a kind of for processing the whole hard alloy single-blade milling cutter of light-alloy, such as Fig. 1 institute Show, the spiral helicine cutting portion 2 including knife handle 1 and positioned at 1 front end of knife handle, the side of the cutting portion 2 is spiral master Cutting edge 3, the part that the spiral main cutting edge 3 extends to end face is the negative cutting edge 4 in end face, the spiral helicine cutting portion 2 Hollow parts be dregs guiding groove 5.

With reference to Fig. 4, the helical angle 31 of spiral main cutting edge 3 is 25 °, is convenient for chip removal；All edge clearance angles of spiral main cutting edge 3 32 be 12 °, and rake angle 33 is 20 °, and cutter is made to possess the lesser angle of shear, and cutting is sharp, can obtain preferable any surface finish Degree.

The flank width 34 of spiral main cutting edge 3 is 1.2mm, and flank step back high 35 is 0.9mm.

The flank width 34 of spiral main cutting edge 3 is designed as 1.2mm, and cutter flank is avoided to generate high point and workpiece hair Raw friction, influences machined surface quality；Flank step back high 35 is designed as 0.9mm, increases cutter chip space.

With reference to Fig. 3, the end clearance angle 41 of the negative cutting edge 4 in end face is 5 °, and sideshake is 4 °.

With reference to Fig. 2, the groove angle 51 of dregs guiding groove 5 is 60 °~90 °, and the radius of slot bottom fillet 52 is R4~R6mm.

Dregs guiding groove 5 is handled using mirror grinding.

Slot bottom is designed compared with Rouno Cormer Pregrinding Wheel, and carries out mirror grinding processing, is reduced the friction that iron filings and tool matrix generate, is made iron Bits are along the smooth chip removal of dregs guiding groove.

The utility model has the beneficial effects that when solving processing light-alloy components, it is desirable that surface matter with higher The problem of amount, universal cutter is unable to satisfy such processing request.The wound of the processing light-alloy whole hard alloy single-blade milling cutter Newly, key technology is breached, solves the processing problem that certain light alloy material parts processing surfaces are mirror surface requirement.

The above, the only preferred embodiment of the utility model, are not intended to limit the protection of the utility model Range.
