Processing Example 1: Dimensional Accuracy (Automotive Parts: 28 mm)

We will achieve a dimensional accuracy of Φ2.0±3μ for a material diameter of Φ3.0!

As an example of Nagaoka Seiki's machining capabilities, we would like to introduce our dimensional accuracy. For automotive parts made from DSH400F material, we have achieved a dimensional accuracy of Φ2.0±3μ at the arrow points in the image, with a material diameter of Φ3.0. Since the cutting area is long, it is a machining process that requires careful consideration of the balance of each dimension. At Nagaoka Seiki Manufacturing, we accept precision parts machining using NC automatic lathes, from common materials such as stainless steel, aluminum, copper, and brass to difficult-to-cut materials. We specialize in high-precision machined parts (dimensional accuracy and mirror surface accuracy) and are committed to manufacturing with a constant focus on QCD.

Processing Example 2 Surface Accuracy (Automotive Parts: 15mm)

This is a machining example from Nagaoka Seiki Seisakusho. The surface accuracy is finished with a surface roughness of RZ1.5 for the cutting part.

As a machining example from Nagaoka Seiki, we would like to introduce surface accuracy. For automotive parts made of SUS303 material, the surface roughness of the machined section is finished at RZ1.5, as indicated by the arrow in the image. In particular, the surface roughness of the tapered section tends to be poor, requiring careful machining. At Nagaoka Seiki Manufacturing, we handle precision machining of parts 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.

Processing Example 4: Dimensional Accuracy (Automotive Parts: 56mm)

The dimensional accuracy at four locations is finished within ±3μ!

As a machining example from Nagaoka Seiki, we would like to introduce dimensional accuracy. For automotive parts made from DSH400F material, the dimensional accuracy at the four indicated points in the image is finished within ±3μ (the tolerances for each dimension indicated by the arrows in the image are ±5μ to ±3μ). Nagaoka Seiki Manufacturing accepts precision parts machining using NC automatic lathes, from common materials such as stainless steel, aluminum, copper, and brass to difficult-to-cut materials. In particular, we specialize in high-precision machined parts (dimensional accuracy, mirror surface accuracy) and are committed to manufacturing with a constant focus on QCD.

High-precision plates including grinding processing *Special materials are currently being offered.

A technique achieved through consistent engineering! "How to achieve flatness in cutting processes before grinding?" is the key processing point!

Typically, after machining, if flatness and surface roughness are required, it is essential to request an external grinding contractor. However, there are often cases where "there is no deadline and we want to keep unnecessary costs down." Our company can manage not only deadlines but also scratches, tolerances, and surface roughness with our integrated process, making it possible to achieve overall cost reduction. Even if grinding is not necessary, we can respond with cutting technology. 【Features】 ■ Expertise achieved through an integrated process ■ Management of scratches, tolerances, and surface roughness ■ Overall cost reduction is achievable ■ Can respond with cutting technology even if grinding is not necessary *For more details, please refer to the PDF document or feel free to contact us.
