Abstract
The invention belongs to part processing technique field, and in particular to a kind of metal shell hole machined technique, it comprises the following steps：1) tool diameter is selected：A) open thick tool diameter standard be D1 it is thick=D X, wherein D be functional hole narrow slot width, X=0.3mm, it is twolip to drive thick cutter；B) tool diameter standard with nothing left is D1 essences=D X1, and wherein D is functional hole narrow slot width, and X1=0.3~0.5mm, cutter with nothing left is left-handed knife, and chip removal direction is bottom chip removal, and R1 essences=D1 essence/2, R1 essences are less than R, functional hole minimum angle R=D/2；Tool blade length with nothing left is more than most short function hole depth+0.5mm；2) machined parameters are selected；3) processing mode is selected：A) during roughing, thick cutter both ends subdrilling milling chip-removal hole is opened, then single line or reciprocating feed；When b) finishing, finishing tool walks two knives, along inverse each knife.Present invention process processing hole efficiency high, breaking is not easy, and qualification rate is high.
Description
Technical field
The invention belongs to part processing technique field, and in particular to a kind of metal shell hole machined technique.
Background technology
" functional hole " of metal shell (such as in industry at present：The narrow slots such as power supply/volume hole/SIM card) processing problem be present
It is as follows：
1. hole slot is narrow (normally only 1.30~1.60MM), because process tool is smaller from diameter, rigidity deficiency, easily
Viscous knife, breaking, length and width are uncoordinated, and assembling is difficult；
2. hole slot edge is sharp edge, processing easily produces the burr to turn up, and after sharp edge deburring, causes to step on side and does not conform to
Lattice.
The content of the invention
It is an object of the invention to provide a kind of metal shell hole machined technique of standardization, and hole is processed using the technique, its
High in machining efficiency, good processing stability, it is not easy breaking, is not likely to produce burr, and the hole qualification rate processed is high.
A kind of metal shell hole machined technique, comprises the following steps,
1) tool diameter is selected：A) open thick tool diameter standard be D1 it is thick=D-X, wherein D be functional hole narrow slot width, X
=0.25~0.35mm, it is twolip to drive thick cutter；B) tool diameter standard with nothing left is D1 essences=D-X1, and wherein D is that functional hole is narrow
Well width, X1=0.3~0.5mm, cutter with nothing left are left-handed knife, and chip removal direction is bottom chip removal, and R1 essences=D1 essence/2, R1 are smart
Less than R, functional hole minimum angle R=D/2；Tool blade with nothing left, which is grown, is more than most short function hole depth+X2, and the X2=0.4~
0.6mm；
2) machined parameters are selected：
3) processing mode is selected：A) during roughing, thick cutter both ends subdrilling milling chip-removal hole is opened, then single line or reciprocal
Formula feed；When b) finishing, finishing tool walks two knives, along inverse each knife.
Preferably, the X=0.3mm.
Preferably, the X2=0.5mm.
Beneficial effects of the present invention are：Using the metal shell hole machined technique of the standardization, during its machining function hole,
Efficiency high, good processing stability, it is not easy breaking, is not likely to produce burr and qualification rate is high.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to this hair
It is bright to be further elaborated.It should be appreciated that specific embodiment described herein and does not have to only to explain the present invention
It is of the invention in limiting.
A kind of metal shell hole machined technique, comprises the following steps,
1) tool diameter is selected：A) open thick tool diameter standard be D1 it is thick=D-X, wherein D be functional hole narrow slot width, X
=0.3mm (is used for chip removal), and it is twolip to drive thick cutter；B) tool diameter standard with nothing left is D1 essences=D-X1, and wherein D is function
Hole narrow slot width, X1=0.3~0.5mm, cutter with nothing left are left-handed knife, and chip removal direction is bottom chip removal, R1 essences=D1 essence/2,
R1 essences are less than R, functional hole minimum angle R=D/2；Tool blade length with nothing left, which is more than most short function hole depth+0.5mm, (to be prevented vibrated
Greatly)；
2) machined parameters are selected：
3) processing mode is selected：A) during roughing, thick cutter both ends subdrilling milling chip-removal hole is opened, then single line or reciprocal
Formula feed；When b) finishing, finishing tool walks two knives, along inverse each knife.
The present invention processes work for functional hole (narrow slot such as power supply/volume hole/SIM card) CNC of metallic mobile phone shell class product
Skill standard, mainly apply to the standardization of CNC section metal products processing technology.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modification, equivalent substitution or improvement made within refreshing and principle etc., should be included in the scope of the protection.
Claims (3)
