Embodiment 1

[0033] Such as Figure 1-5 As shown, the PCB milling cutter with automatic chip removal capability of the present invention includes a handle 1 and a blade 4 fixedly connected to the handle 1. The lower part of the handle 1 forms a connecting portion with an outer diameter equal to the blade 4. On the connecting portion An installation groove is provided, and the magnetic strip 2 is fixedly installed in the installation groove, and the blade portion 4 is fixedly connected with the connection portion through the welding portion 3. The outer diameter of the welding portion 3 is equal to the outer diameter of the blade portion 4, and the blade portion 4 is also installed on the row chip device. The chip removal device includes a sleeve, a magnetic strip 2 and a fan blade 9 installed on the outer surface of the lower part of the sleeve. The sleeve is sleeved on the outer surface of the blade 4, and the length of the sleeve is greater than the length of the blade 4 and less than th...

Embodiment 2

[0041] The difference from Embodiment 1 is that the blade portion 4 of the PCB milling cutter of the present invention includes a substrate 41 and a bottom layer 42 deposited on the surface of the substrate 41, an anti-oxidation layer 43 and a wear-resistant layer 44, and the bottom layer 42, the anti-oxidation layer 43 and the anti-oxidation layer The grinding layer 44 is attached to the surface of the milling cutter base 41 from the inside to the outside in sequence, the bottom layer 42 is niobium; the anti-oxidation layer 43 contains niobium, silicon, chromium, titanium, zinc and samarium; the wear-resistant layer 44 is silicon nitride / nitride Titanium aluminum niobium.

[0042] The preparation method of the cutting edge comprises the following steps: degreasing the substrate using the method of the prior art, cleaning with an organic solvent, rinsing and drying with deionized water; -3 Below Pa, at a temperature of 340°C, perform gas plasma cleaning on the substrate. The s...

Abstract

The invention discloses a PCB milling cutter with automatic chip removal capacity. The PCB milling cutter comprises a cutter handle and a blade part fixedly connected with the cutter handle, a connecting part with the outer diameter equal to that of the blade part is formed on the lower portion of the cutter handle, the blade part is fixedly connected with the connecting part through a welding part, and the outer diameter of the welding part is equal to that of the blade part; and a chip removal device is further mounted on the blade part, and the blade part comprises a base body, and a bottom layer, an anti-oxidation layer and a wear-resistant layer which are deposited on the surface of the base body. The PCB milling cutter overcomes the defects in the prior art, is good in durability and has the automatic chip removal capacity, meanwhile, the milling cutter can be used for multiple times after being trimmed, resources are saved, and material waste is reduced.

Description

technical field [0001] The invention relates to the technical field of PCB milling cutters, in particular to a PCB milling cutter with automatic chip removal capability. Background technique [0002] The milling cutter used in PCB is also called gong cutter, which is used in the post-PCB process (or pressing and fishing frame). The main purpose is to use this cutter to cut the finished circuit board into individual PCS or SPNL and then ship it to client. That is, the final product size required by the customer. This tool is mainly used for cutting, the cutting edge and the force direction are in the horizontal direction, similar to the drill, but the force and cutting direction of the drill are at the drill tip. There are two types of milling cutters: fishtail type and drill point type. The special design focuses on the service life and removal effect of the milling cutter. It is characterized by large chip removal grooves, which make the chip removal smooth during drillin...
