Processing Example 3: Inner Diameter Precision (Information Communication Equipment: 18 mm)

This is a machining example from Nagaoka Seiki Seisakusho. It finishes with a tolerance of ±2μ for an inner diameter of Φ0.25.

As a machining example from Nagaoka Seiki, we would like to introduce our inner diameter precision. For information communication equipment made from C3604 material, the inner diameter has been finished with a tolerance of ±2μ at the Φ0.25 indicated by the image arrow. Since the inner diameter is narrow, careful management of the cutting tools is required for this machining. At Nagaoka Seiki Manufacturing, we accept precision parts cutting using NC automatic lathes, from common materials such as stainless steel, aluminum, copper, and brass to difficult-to-machine materials. We specialize in high-precision machined parts (dimensional accuracy, mirror surface accuracy) and are committed to manufacturing with a constant focus on QCD.
