Problems solved by technology
At present, the saw blade limit stop of the cutting machine generally used is a copper stop made in advance, and its production cost is relatively high, and due to the deviation of the size matching accuracy, the saw blade wear limit stop is easy to appear after installation. The problem caused serious local defects in the limit stop; after the installation of the copper limit stop, the gap between the saw kerf channel is generally 4.8mm, and the width of the saw blade is 4.5mm. The contact part of the block is suspended in the air, resulting in problems such as poor board edge and serious wear of the saw blade after the workpiece is cut.

Embodiment Construction
[0019] Such as Figure 1 to 4 The method for limiting the position of the saw blade of a circuit board cutting machine includes the following steps:
[0020] 1) Prepare a phenolic resin board 1 and cut it into a size of 85mm×500mm;
[0021] 2) Use a milling machine to mill out the chuck rail 2 and the screw positioning hole 3 of the cutting machine on the phenolic resin board 1;
[0022] 3) Fix the processed phenolic resin board 1 on the cutting machine with screws, start the operation, and open a saw blade channel 4 in the middle of the phenolic resin board 1, such as figure 1 , 2 , 3 shown.
[0023] The phenolic resin board 1 uses a milling machine phenolic resin backing plate discarded in the circuit board molding process, and has a thickness of 12 mm.
[0024] The width of the saw blade channel 4 is the same as the width of the saw blade, which is 4.5 mm.
[0025] The position and size of the chuck channel 2 and the screw positioning hole 3 correspond to the cutting machine and are ...

The invention discloses a limiting method for a circuit board cutting machine saw blade. The limiting method is characterized by comprising the follow steps: 1) preparing a piece of phenolic resin board and cutting the phenolic resin board into a sheet material with a 85 mm * 500 mm specification; 2) using a milling machine to respectively mill out a chuck track and a screw positioning hole of a cutting machine on the phenolic resin board; 3) and using screws to fix the machined phenolic resin board on the cutting machine, starting and enabling the cutting machine to operate, and a saw blade passageway is dug out in the middle of the phenolic resin board. The method is to change materials of a limit stop from copper to phenolic resin and reduce abrasion to a blade of the cutting machine caused by the copper. In addition, after the phenolic resin limit stop is mounted on the cutting machine, the saw blade passageway is dug out so as to enable measurement coordinating precision of the saw blade of the cutting machine to be greatly improved, abrasion of the saw blade is reduced, and edge quality is greatly improved after a workpiece is cut.
Description
Technical field [0001] The invention relates to a method for limiting a saw blade of a circuit board opener, in particular, to a processing method for a limiting block of a saw blade of a opener. Background technique [0002] In the production process of printed circuit board companies, they need to cut the purchased copper clad laminate, aluminum cover board, paper backing board and other large-size materials into various specifications and small-size finished products that need to be cut. This requires a cutting machine. At present, the saw blade limit stop of the generally used cutting machine is made in advance, and the production cost is relatively high, and due to the deviation of the size matching accuracy, the saw blade is prone to wear the limit stop after installation The problem caused by the partial defect of the limit stop is serious; the gap of the saw channel after the installation of the copper limit stop is generally 4.8mm, and the width of the saw blade is 4.5mm...
