Embodiment 1

[0058] A method for processing the front case of a mobile phone. The front case 10 of the mobile phone has a light guide hole 20. The processing method includes: injecting a steel plate and plastic to obtain the front case 10 of the mobile phone with a plastic area; fixing the front case 10 of the mobile phone to a CNC drill. On the hole processing machine tool; start the CNC drilling machine tool, so that the cutter 30 on the CNC drilling machine tool forms the light guide hole 20 on the plastic area, the rotating speed of the CNC drilling machine tool is 160000r / min, and the blade on the tool 30 passes through It is processed by CNC, the blade length is 0.9 mm, and the diameter of the light guide hole 20 is 0.15 mm. Preferably, the working pressure of the CNC drilling machine is 1100 MPa.

Embodiment 2

[0060] A method for processing the front case of a mobile phone. The front case 10 of the mobile phone has a light guide hole 20. The processing method includes: injecting a steel plate and plastic to obtain the front case 10 of the mobile phone with a plastic area; fixing the front case 10 of the mobile phone to a CNC drill. On the hole processing machine tool; start the CNC drilling machine tool, so that the cutter 30 on the CNC drilling machine tool forms the light guide hole 20 on the plastic area, the rotating speed of the CNC drilling machine tool is 150000r / min, and the blade on the tool 30 passes through It is processed by CNC, the blade length is 0.85 mm, and the diameter of the light guide hole 20 is 0.1 mm. Preferably, the working pressure of the CNC drilling machine tool is 1200 MPa.

Embodiment 3

[0062] A method for processing the front case of a mobile phone. The front case 10 of the mobile phone has a light guide hole 20. The processing method includes: injecting a steel plate and plastic to obtain the front case 10 of the mobile phone with a plastic area; fixing the front case 10 of the mobile phone to a CNC drill.

Abstract

The invention provides a mobile phone front shell, a machining method thereof, a mobile phone and a machine tool. The machining method comprises the following steps: performing injection molding on asteel plate and plastic to obtain the mobile phone front shell with a plastic area; fixing the mobile phone front shell onto a CNC drilling and machining machine tool; and starting up the CNC drillingand machining machine tool to enable a tool on the CNC drilling and machining machine tool to form a light guide hole in the plastic area. Through the technical scheme, the problem that a light guidehole of a conventional mobile phone front shell is difficult to machine on a die is solved, a pillar on the die has low probability of being broken by punching, volume production of the mobile phonefront shell can be realized, the production cost is lowered, and the machining efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile phone accessories, in particular to a processing method for a mobile phone front case, a mobile phone front case made by the above processing method, a mobile phone using the above mobile phone front case and a CNC drilling Processing machine tools. Background technique [0002] At present, the holes made on the plastic of mobile phones are generally formed on the mold, but for some special holes, such as when processing extremely fine micro-holes below 0.2mm, because the molding of general mobile phone cases is driven by high injection and high pressure, the mold The upper 0.20mm column is easy to be punched and cannot be mass-produced. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] For this reason, the first object of the present invention is to provide a method for proces...
