A little attached drawings obtain other relevant attached drawings.
Fig. 1 is the cutter track trajectory diagram of the milling method provided by the invention for improving surface roughness.
[specific embodiment]
It is clear in order to be more clear the purpose of the present invention, technical solution and advantageous effects, below in conjunction with attached drawing and
Specific embodiment, the present invention will be described in further detail.It should be understood that specific implementation described in this specification
Mode is not intended to limit the present invention just for the sake of explaining the present invention.
The present invention provides a kind of milling method for improving surface roughness.
Referring to Fig. 1, in an embodiment of the present invention, the milling method for improving surface roughness is first using hard
Alloy milling cutter process and reserve on the machined surface of workpiece 10 20 machining allowance of 0.1mm thickness, then uses PCD
(Polycrystalline diamond polycrystal diamond cutter) milling cutter processes the machining allowance, and the PCD is milled
The machining allowance is divided into multiple machined layers to improve the surface roughness of machined surface 20 by carrying out repeatedly processing by knife, and
Each machined layer with a thickness of 0.02-0.05mm.In the present embodiment, the revolving speed of carbide-tipped milling cutter is 10000-
18000r/min, amount of feeding 2000-3000mm/min, milling depth 0.1-0.3mm;The revolving speed of PCD milling cutter is 15000-
20000r/min, amount of feeding 2000-3000mm/min.
It is understood that PCD milling cutter have high rigidity, high-termal conductivity, the coefficient of expansion, high elastic modulus, low friction
Coefficient and the extremely sharp feature of blade, and PCD milling cutter there are also with non-ferrous metal and it is nonmetallic between the lesser feature of affinity,
So that the machining accuracy of PCD milling cutter is higher and can mill out the good plane of finish (surface roughness can achieve
Ra0.06), costly because of PCD milling cutter, to first use PCD milling cutter to the machined surface of workpiece 10 again using carbide-tipped milling cutter
20 carry out Milling Process, it is possible to reduce the processing capacity of PCD milling cutter to reduce the abrasion of PCD milling cutter, and then is reduced and is processed into
This.
Further, in one embodiment, carbide-tipped milling cutter and PCD milling cutter are all made of hollow cutter track to workpiece 10
Machined surface 20 is processed, also that is, when processing, carbide-tipped milling cutter and cutter track rail of the PCD milling cutter on machined surface 20
Mark 30 is in " returning " font, in this way, carbide-tipped milling cutter or PCD milling cutter can be milled by the longitudinal direction on cutter track track 30 and laterally
Dynamic balance is cut, mismachining tolerance is reduced, improves machining accuracy.
Further, in one embodiment, the machining allowance is divided into three machined layers by PCD milling cutter, and three add
The thickness installation process sequence of work layer is sequentially reduced, and PCD milling cutter is processed thick with the surface for improving machined surface 20 three times
Rugosity.Specifically, PCD milling tool first is closed by hard with can effectively remove on machined surface 20 after second machined layer
The knife mark and connect knife step that golden milling cutter generates, PCD milling tool third machined layer is then used to improve the rough surface of machined surface 20
Degree.In the present embodiment, the thickness installation process sequence of three machined layers is followed successively by 0.05mm, 0.03mm and 0.02mm, also
That is, first machined layer maximumlly to remove the knife mark generated by carbide-tipped milling cutter and connects knife platform with a thickness of 0.05mm
Rank, second machined layer are 0.03mm to completely remove the knife mark generated by carbide-tipped milling cutter and connect knife step, and third adds
Work layer is 0.02mm with the surface roughness for improving machined surface 20.It learns after actual measurement, the work processed using the milling mode
10 surface of part can achieve the surface roughness of Ra0.06.
It should be noted that work to be conducive to the milling of PCD milling cutter, the milling of the last time processing of carbide-tipped milling cutter
Depth is 0.1mm, to avoid forming deeper knife mark on machined surface 20 and connecing knife step.For example, 10 machined surface 20 of workpiece
Total machining allowance is 0.4mm, and carbide-tipped milling cutter first uses the milling depth of 0.2mm to carry out time processing, then using 0.1mm's
After milling depth is processed, so that the machining allowance for reserving 0.1mm thickness gives PCD milling cutter, then PCD milling cutter adds according to above-mentioned
Work mode carries out Milling Process three times.
In summary, it is to be understood that the present invention carries out slightly the machined surface 20 of workpiece 10 by carbide-tipped milling cutter
To reserve to the machining allowance of PCD milling cutter, machining allowance is divided into repeatedly processing again to obtain rough surface by PCD milling cutter for processing
Good machined surface 20 is spent, and reduces the abrasion of PCD milling cutter, PCD milling cutter service life is improved, reduces processing cost.
The present invention is not only in the description and the implementation described, therefore for the personnel of familiar field
Other advantage and modification is easily implemented, therefore in the essence without departing substantially from universal defined by claim and equivalency range
In the case where mind and range, the present invention is not limited to specific details, representative equipment and diagrams shown and described herein
Example.
