Embodiment Construction

[0027] A method of chamfering using a CNC milling machine, comprising the following steps:

[0028] 1] Process CNC milling cutters according to the chamfering requirements required by customers;

[0029] The CNC milling cutter adopts the sinking hole drill, and the drill point angle of the sinking hole drill is selected according to the edge chamfering requirements of the printed board; the blade handle of the sinking hole drill is a fixed handle and matches the fixture of the CNC milling machine;

[0030] 2] Install the processed CNC milling cutter on the fixture of the CNC milling machine.

[0031] This method can be applied to the edge beveling of printed boards, specifically:

[0032] 3) On the processing drawing, find out the edge to be poured of the printed board, the angle of the poured edge and the depth requirement;

[0033] 4) Retrieve the drilling file, use the large hole above 3.0 on the printed board as the positioning hole, re-edit the drilling file, and define...

Abstract

A method of chamfering using a CNC milling machine. On the basis of the existing milling machine, the CNC milling cutter of the milling machine is improved to complete the chamfering. The chamfering requirements are selected; the shank of the sinking hole drill matches the fixture of the CNC milling machine. By adopting the method of the present invention, any angle of chamfering can be processed, and the cost of purchasing chamfering equipment is saved. The cost of the chamfering machine is about 10,000 to 100,000 yuan, while the cost of the special milling cutter of the present invention is only 46 yuan .

Description

technical field [0001] The invention belongs to the field of printed board production, and relates to a method for edge beveling of printed boards. Background technique [0002] When the printed board is installed, sometimes the insulation layer of the wires or even the wires are broken. After analysis, the reason is that when the wiring harness crosses the edge of the motherboard, the right-angled part of the edge of the motherboard is too sharp, which causes the cable to wear. Abraded products usually cannot withstand the vibration test of military products and cannot meet customer requirements. [0003] There are currently two methods of chamfering: [0004] 1. One is done by hand. The disadvantages of manual edging are poor product consistency, low efficiency, easy to produce waste products, and the inability to guarantee the blunt edge angle required by customers. [0005] 2. Rely on the beveling machine for bevelling. The disadvantage of the beveling machine is tha...
