Embodiment
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiment.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all should belong to the scope of protection of the invention.
Refer to Fig. 1, a kind of display screen component method for making that embodiment of the present invention provides.Be understandable that; Described display screen component is applied in terminal, is especially applied on mobile phone, thus the convenient replacing to mobile phone display screen component, dismounting.Described display screen component method for making comprises the following steps:
Step 101: a unprocessed glass plate sections is provided.
In present embodiment, described unprocessed glass plate sections can be obtained by pressure roller moulding process, also can be obtained by cutting technique, can also be to prolong compression technology acquisition by building.The transmittance of described unprocessed glass plate sections need reach more than 90%, thus makes the display effect of terminal good; The flatness of described unprocessed glass plate sections is at 0.005mm ~ 0.01mm, and concrete preferred 0.005mm, thus the surface smoothing making described seamless terminal protecgulum, outward appearance is good.In other embodiments, the flatness of described unprocessed glass plate sections can also be 0.008.
Step 102: the periphery processing described glass plate sections, obtains the glass plate of preset shape.
Described high-precise numerically controlled milling machine adopts diamond milling cutter to carry out milling to described glass plate sections, and can the end face of described diamond milling cutter can be sphere, and also can be plane, can also be the conical surface.To facilitate the peripheral milling of described CNC milling machine to described glass plate sections to cut out arc surface or plane, or the conical surface.Man-hour is being added to described glass plate sections, is needing to select minimum process error to be the CNC milling machine of 0.002mm, and in advance the machined parameters of CNC milling machine is set, and in advance milling cutter machining path is set.
In present embodiment, described CNC milling machine arranges glass plate described in multiple working procedure milling, and given every procedure is to the processing dimension of described glass plate sections; Divide again multiple loop cycle to process in every procedure, set the feeding size in each cycle, thus realize the processing dimension in described every procedure.Concrete described processing dimension and feeding Size calculation, actual in following formula:
N=L/1, wherein N is the periodicity in every procedure, and L is processing dimension, and 1 is feeding size.Such as: in a procedure, unprocessed glass plate sections width dimensions is 80.105mm, and the glass plate sections width dimensions after processing is 80.005mm, then L=0.1mm, setting 1=0.01, then N=10.Namely described in a procedure, all fate 10 cycles of CNC milling machine to described glass plate sections carry out milling, and then the processing dimension realized in a procedure is 0.1mm.
