Abstract

The invention relates to a machining method for plate perforating. A plate includes metal layers and non-metal layers which are arranged layers upon layers, and the machining method includes the stepsthat (1) drill holes which can sequentially penetrate through the metal layers and the non-metal layers are formed in to-be-machined plates through a drilling tool; the hole diameter of the drill holes is less than that of a final hole; (2) a drilling hole position is subjected to hole milling from the metal layers to the non-metal layers through a spiral milling cutter; the cutter diameter of the spiral milling cutter is equal to the hole diameter of the final hole; and (3) a hole milling position is subjected to hole milling from the metal layers to the non-metal layers through an end mill,and the diameter of the end mill is equal to the hole diameter of the final perforating. According to the machining method for the plate perforating, machined hole walls and hole bottoms do not haveburrs, and machined holes are high in quality, thereby ensuring the plate quality.

Description

technical field [0001] The invention relates to the field of plate processing, in particular to a processing method for opening holes in a plate. Background technique [0002] In mobile terminal devices, such as mobile phones and tablet computers, where the frame or back cover includes a metal layer and a non-metal layer connected thereto, holes are often required to be formed on the middle frame or bottom plate. The traditional drilling method is to directly use the drill bit to drill the hole, but when the drill bit is used to break the hole, there will be flaky burrs at the bottom of the hole. There are many defective frames or back covers. Contents of the invention [0003] Based on this, it is necessary to solve the problem of flaky burrs left at the bottom of the hole after directly drilling the middle frame or the back cover with a drill bit, and provide a processing method for opening holes without burrs. [0004] A processing method for opening holes in a plate....
