This product is the core component of the high-end coffee extraction device in the field of food machinery, and is precision manufactured with SUS304 food-grade stainless steel. For its unique microhole array machining requirements - 1,700+ microholes with a diameter of 0.4mm and a depth-to-diameter ratio of 1:3 on the matrix, we used a high-speed CNC drilling machine.

With a high-speed CNC drilling machine equipped with a UHF spindle (60,000rpm), combined with cemented carbide coated micro-drilling and a special cooling lubrication system, the single-hole machining cycle is optimized to an industry-leading 6 seconds.

Especially in the optimization of processing parameters, the high-speed CNC drilling machine adopts adaptive feed control technology to dynamically match the spindle speed, feed rate and material cutting resistance, while ensuring the tolerance of ±0.01mm aperture, creating a process record of zero fracture of the whole batch of processing bits, and finally achieving a 100% pass rate of the product. Meet the hygienic requirements of food machinery for surface roughness of fluid channels.
