Case study of mass production processing of fine diameter deep holes for semiconductor devices.
Achieving stable mass production processing even under long-length conditions with a diameter of 1.5mm.
This case study involves mass production of parts for semiconductor manufacturing equipment, specifically focusing on deep hole machining with a diameter of φ1.5mm. Despite the long length condition of approximately 180mm, we have established stable machining conditions through gun drilling, maintaining a production rate of over 200 pieces per day. Due to the small diameter and high L/D ratio, issues such as vibration during machining and variations in inner diameter are challenges; however, we have stabilized inner diameter accuracy by optimizing setup methods and cutting conditions. No defects have occurred in the full inspection, ensuring both reproducibility and supply stability for mass-produced parts. 【Features】 ■ Mass production achievements for φ1.5mm fine diameter deep holes ■ Stable inner diameter accuracy even under long length conditions ■ Capable of continuous production exceeding 200 pieces per day ■ Quality control system through full inspection *For more details, please download the PDF or feel free to contact us.
