Why Does CNC Turning of Small Parts Require High Machine Stability and Advanced Operator Skills?

CNC turning of small components at Yamaguchi Vietnam – meeting stringent requirements for precision, repeatability, and stability in every detail.

In the field of precision engineering, small components such as shafts, pins, bushings, and positioning rings typically measure from just a few millimeters to several tens of millimeters, with extremely tight tolerances. Machining these parts by CNC turning not only requires high-precision machinery, but also absolute machine stability and advanced operational skills from experienced technicians.

■ Why are machine stability and operator skill decisive factors?

Small parts are highly susceptible to dimensional deviation caused by even minimal vibration → Machines must have rigid structures and highly accurate drive systems.

Tight tolerances demand precise cutting tools, cutting parameters, and fixturing → Technicians must have deep knowledge of materials and machine behavior.

Visual inspection is difficult → Experience must be combined with high-precision measuring equipment.

Yamaguchi Vietnam has been continuously producing large volumes of small CNC-turned parts for Japanese and U.S. customers, meeting precision requirements of ±0.01 mm. These achievements are the result of a strong combination of advanced CNC equipment and a highly experienced workforce specialized in quality control.
