Introduction to Micro-Hole Machining

Micro-hole machining is an advanced precision manufacturing technique engineered to produce extremely small aperture structures. Utilizing high-speed rotational cutting tools and advanced thermal-controlled processes, it consistently maintains strict dimensional tolerances and precise geometric hole positioning across various metals and engineering plastics. This technology is critical to ensuring optimal microfluidic, gas transmission, and wafer vacuum suction performance. Common applications and features include semiconductor vacuum chuck micro-holes, medical injection and airflow micro-holes, precision dispensing nozzles, and aerospace filtration or cooling micro-holes.
