Cutting and splitting of aluminum substrate, copper substrate and glass fiber board with V-CUT

Introduction

1. Using a unique cutting method, the circuit board is cut by six blades. The upper and lower two pieces form a group to form a cutting unit. There are three groups A , B , and C. The whole cutting process is divided into three stages, A The group blade cuts 40% of the circuit board first , and then the B blade runs through the groove cut by the A blade again to complete 40% of the cutting volume. Finally, the C blade cuts the last 20% and trims, because each time The amount of cutting is small, so the stress generated during the cutting process is reduced by more than 80% compared with the traditional one-time cutting method . The edge of the divided circuit board is flat and smooth, and the board surface is very flat, not twisted or warped, which is the only guarantee on the market. A machine that does not deform the aluminum substrate after cutting;

2, due to multiple reasons cutting, the cutting process is very stable, greatly improving the V-CUT positioning capability groove, even if V-CUT groove shallow circuit board does not appear V-CUT grooves come out from the guide blade Situation, to avoid bad;

3. The cutting force of the blade is small, and the high-speed steel material imported from Sweden is adopted, and the blade is durable;

4. All cutting blades adopt the standard of dual-frequency laser interferometer to ensure that the rear knife can accurately and intermittently cut in the groove cut by the front knife. The blade tip runout is not more than 0.02mm to ensure perfect cutting quality.
