Parts Seiko News [October 2025 Issue]
This time, we would like to introduce "deep hole measurement" and "deep hole machining."
Do you have any difficulties with machining methods or measurement methods for fine hole machining products with depths of 100mm or even up to 300mm? Our company can provide high-precision measurement using roundness measuring instruments.
*While some similar measurements can be performed with a gantry-type three-dimensional measuring instrument, it can measure a maximum of about 50 reference points, whereas the roundness measuring instrument can measure over 10,000 reference points, allowing for a more precise evaluation.
*Measurement results can be provided as data for shape confirmation or in document format.
In deep hole machining, there are cases where it is difficult to respond using NC lathes or machining centers. Our company flexibly accommodates deep hole machining using gun drilling, as well as long parts and high-precision components, in collaboration with partner factories.
We can meet strict quality requirements such as roundness, cylindricity, and straightness of 0.005mm, and surface roughness corresponding to JIS symbol ∇∇∇∇ (Ra0.2). With our track record in precision machining and quality management system, you can trust us with your requests.
Please feel free to contact us.
