Always Looking to New Horizons;A Never-Ending Quest for New Challenges

Here we are, well into the 21st century, and TNK Sanwa Precision has the leading share of the world market for precision microshafts. We got here by constantly expanding and improving our technology, manufacturing, and quality control.
We have established two of our plans at China, where we have boosted production though further expansion and dramatically improved our management standards through certification for the ISO 9001 and TS 16949 quality management standards, and the ISO 14001 environmental management standard. The bottom line is that we can now better meet the needs of our international customers.
In Japan, meanwhile, we have attained a unique position as a comprehensive metal working company that also develops new products. We have achived this by building an integrated system for grinding, press working, cutting, and heat treatment, with technologies and equipments among the most advanced in the industry in each of these fields.
That is why the products that we have developed jointly with customers have come to represent the norm in fields including automotive, machinery, semiconductors, and telecommunications, to name a few.
To continue to meet the needs of our customers, we will go on using an undaunted frontier spirit to take our creative technology higher and farther than ever.
When you need something that has never been built, something that our competitors cannot build, or when you are not satisfied with what you have now, then we at TNK Sanwa Precision are ready to help you.
