Customer Background

Production context behind the case.

This project comes from a Medical manufacturing requirement for Surgical instrument. The buyer needed stable machining quality, repeatable inspection results and a machine configuration suitable for real production rather than a one-time sample.

Machine Selection

Why this machine configuration was selected.

HYR-CNC selected the machine plan around part size, material, tolerance, surface finish, tool capacity and expected production volume. The recommended setup focuses on rigidity, spindle stability, fixture access, tool change efficiency and inspection control.
