Meltblown cloth is the core material of the mask. Meltblown cloth mainly uses polypropylene as the main raw material.

The key component of the melt-blown fabric is the melt-blown die head (spinneret), which is a precision product. On a high-hardness stainless steel, the CNC machine tool is used to drill a diameter of only 2-3 hairs. Microporous. The hole diameter is small, the hole depth is long, and the length-to-diameter ratio of the tool reaches 20: 1 during processing. The difficulty can be imagined.

In order to meet the processing requirements, we choose the supporting GSK system high-speed vertical plus, combined with GSK linear motor drive. It can maximize the machining performance of the machine tool and realize the efficient and high-quality machining of micro holes.
