PCB board sub-board cutting, need to cut in batches, improve processing efficiency, one-time cutting, reduce scrap rate, is also the element to pay attention to, some will think, the spindle of the board splitting machine is to choose high-speed or low-speed good, of course, it is good to choose high-speed, will not be burr.
Nowadays, many PCB boards are used in the spindle of the Japanese Nakanishi splitting machine, with a speed of up to 60,000 rpm, a diameter of 30mm, an accuracy of less than 1um, high speed, high-precision cutting, cutting without burrs, and one-time processing to improve the yield rate. And there is also fully automatic processing, online separator cutting, saving tool change time.
NAKANISHI sub-trigger spindle, small size, does not occupy space, cost-effective, and stable precision processing, many sub-plate machines are equipped with this high-speed, high-precision spindle to improve processing efficiency.
