Introduction of processing examples for difficult-to-cut materials using metal 3D, laser, FIB, fine grooves, and fine holes.
Introduction of high-precision and high-quality precision micro-machining examples of difficult-to-cut materials, including microhole processing with an aspect ratio of 100 times, porous body shaping, and processing of high-melting-point metal materials.
Since its establishment in 1955, we have been dedicated to accumulating experience and know-how in precision microfabrication technology. This precision microfabrication technology began with the production of spinnerets, a key technology in synthetic fiber manufacturing, and is now applied in many industrial fields, including semiconductors, measurement and inspection, aerospace, and medical devices. This time, we will introduce processing examples focusing on difficult-to-cut materials, including metal 3D printing, fine groove processing, laser processing, FIB processing, and high aspect ratio processing. 【Overview of Case Studies】 ◆ Metal 3D Printer * Integrated processing from shaping to finishing * Controlled porous body shaping ◆ Fine Groove Processing * Texturing processing * High aspect ratio (40 times) rectangular groove processing ◆ Laser Processing * High-speed processing for porous plate manufacturing * High-quality hole processing technology * Processing examples for glass and ceramics * Processing examples for high melting point materials (Nb, Ta, W) ◆ FIB Processing * Processing technology for minimum diameter of φ0.1 mm * Introduction of ultra-fine foreign matter samples ◆ High Aspect Ratio Processing * Introduction of fine hole processing examples with an aspect ratio of 100 times
