TNK means ultra-precision grinding with sub-micron accuracy

TNK's advantage is that he is good at sub-micron (1/10000 mm) ultra-precision grinding. We provide high-precision processed products according to customer needs, such as outer diameter, inner diameter, roundness, straightness, cylindricity and roughness. Especially in the field of grinding processing, the shape accuracy reached 0.1m.
These technical capabilities are also used in products and components used in vacuum spaces, such as the aerospace industry and the aerospace industry.

The Chinese factory can also produce precision shafts with the same accuracy as the head office in Japan

For customers who have higher requirements for precision, please understand: Japan ’s head office
Japan Sanhe Precision Shaft Co., Ltd.Japan's largest manufacturer of precision shafts, the company was established in 1946
Production and processing of the same precision micro shaft with higher precision in China
The headquarter of Japan has a larger production scale, better processing level and stricter quality management
Can meet the customer's quantity requirements (from the number of orders)
All processes are fully processed within the company, which can meet the requirements of short delivery time and high quality
Can meet customer's material requirements (stainless steel materials to ceramic materials)
Unique material 15MH, material characteristics:Completely non-magnetic, with unique surface treatment, the hardness can reach HV700
Unique material KWS4MA, material characteristics:Performance is the same as SUS440C, but the price is only 2/3
Focus on the production of various types of precision micro shafts while also producing and processing various types of precision metal parts
When it is difficult to process metal parts,
Please feel free to consult.
