Abstract
The utility model discloses a diamond milling cutter for machining a mobile telephone shell outline. The diamond milling cutter comprises a straight cutter handle made of a hard alloy, wherein the front end of the cutter handle is provided with two blade parts in central symmetry; polymerize crystal diamond (PCD) tool bits are respectively welded on the two blade parts; the blade parts of the milling cutter are provided with a first rear angle and a second rear angle; the cutter handle comprises a large-diameter part and a small-diameter part which are connected together; the PCD tool bit is welded at the front end of the large-diameter part; and the outer edge of the PCD tool bit protrudes out of the outer edge of the large-diameter part along the radial direction of the cutter handle. The cutter handle is made of the hard alloy, so that the shock resistance and rigidity are high. By adoption of the two-blade straight handle design, the machining requirements are met, and the milling cutter is convenient to manufacture. The PCD tool bits are welded at the two blade parts of the front end of the cutter handle, so that the machined workpiece precision and roughness are high. According to the diamond milling cutter, the requirements of performing mechanical finish machining on an aluminum alloy mobile phone shell can be met, the machining efficiency and machining precision are high, and the diamond milling cutter is particularly convenient for performing finish machining on the corner of the aluminum alloy mobile phone shell.
Description
Technical field
The utility model relates to a kind of mobile phone processing technique field, especially a kind of milling cutter.
Background technology
When making the aluminium alloy phone housing, present technological means is to use pressing equipment directly with the phone housing punch forming, does not have further fine finishining after the punch forming, causes phone housing smooth inadequately, and jagged.If adopt the means of artificial polishing, then both increased cost of labor, the low drawback of working (machining) efficiency is arranged again.At present, in the field that makes the aluminium alloy phone housing, lack the milling cutter that cost is low, fine finishining is effective.
The utility model content
The purpose of this utility model is to provide the diamond milling cutter of the outer casing krofile of a kind of processing mobile phone.
For achieving the above object, the diamond milling cutter of the outer casing krofile of processing mobile phone of the present utility model comprises the straight formula handle of a knife that carbide alloy is made, the handle of a knife front end is centrosymmetric and is provided with two blades, and described two-edged portion is welded with the PCD cutter head respectively, and the milling cutter blade is provided with first relief angle and second relief angle.
Described handle of a knife comprises major diameter part and the small diameter portion that links together, and the front end of described major diameter part is welded with described PCD cutter head; Along the radial direction of handle of a knife, the outer rim of the outstanding described major diameter part of the outer rim of PCD cutter head.
The utility model is simple in structure, is convenient to make and use.When making the utility model, use W10 molding sand wheel correct grinding cutting edge, make it have better machining accuracy.Milling cutter adopts carbide alloy to do handle of a knife, and rigidity might as well when shock resistance was good.The utility model adopts the design of two-edged staight shank, and is simple in structure, satisfy make under the condition of processing request fairly simple.Milling cutter of the present utility model can make the workpiece accuracy that processes higher at handle of a knife front end two blades welding PCD cutter head, and roughness is better.The milling cutter blade is designed to two relief angles, is more convenient for to workpiece, especially aluminium alloy phone housing corner is carried out fine finishining, makes its more smooth and beautiful appearance.
It is polycrystalline diamond that cutter head adopts PCD(PCD) material, have following advantage: the hardness height; The thermal conductivity factor height is convenient to the cutter heat and is transmitted rapidly; Coefficient of friction is little, can significantly reduce Tool in Cutting power; Thermal coefficient of expansion is less, and the cutter thermal deformation is little, the machining accuracy height; Affinity is very little between cutter and non-ferrous metal nonmetallic materials, and the process smear metal is not on cutting tip.
In a word, behind use the utility model, can satisfy the aluminium alloy phone housing is carried out the accurately machined needs of mechanization, working (machining) efficiency and machining accuracy are all higher.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the diamond milling cutter of the outer casing krofile of processing mobile phone of the present utility model comprises the straight formula handle of a knife that carbide alloy is made, described handle of a knife comprises major diameter part 1 and the small diameter portion 2 that links together, the front end of described major diameter part 1 is centrosymmetric and is provided with two blades 3, described two blades 3 are welded with PCD cutter head 4 respectively, make the utility model be staight shank two-edged structure.
The end mill(ing) cutter blade is provided with first relief angle and second relief angle (first relief angle and second relief angle are the routine techniques of the art, and size is less, and figure does not show) before the handle of a knife.Along the radial direction of handle of a knife, the outer rim of the outstanding described major diameter part 1 of the outer rim 4A of PCD cutter head 4.
When making the utility model, use W10 molding sand wheel correct grinding cutting edge, make it have better machining accuracy.Making the back and amplify 50 times of detections at microscopically, is qualified products with the product of no sawtooth, no tipping.
The utility model adopts carbide alloy to do handle of a knife, and rigidity might as well when shock resistance was good.The utility model adopts the design of two-edged staight shank, and is simple in structure, satisfy make under the condition of processing request fairly simple.Milling cutter of the present utility model can make the workpiece accuracy that processes higher at handle of a knife front end two blades 3 welding PCD cutter heads 4, and roughness is better.The milling cutter blade is designed to two relief angles, is more convenient for to workpiece, especially aluminium alloy phone housing corner is carried out fine finishining, makes its more smooth and beautiful appearance.
In a word, behind use the utility model, can satisfy the aluminium alloy phone housing is carried out the accurately machined needs of mechanization, working (machining) efficiency and machining accuracy are all higher.
Present embodiment is not that shape of the present utility model, material, structure etc. are done any pro forma restriction; every foundation technical spirit of the present utility model all belongs to the protection domain of technical solutions of the utility model to any simple modification, equivalent variations and modification that above embodiment does.
