NISSIN Manufacturing

What NISSIN Manufacturing does

NISSIN Manufacturing Group Co., Ltd. (株式会社日進製作所グループ) is a Kyoto-headquartered Japanese precision industrial machinery manufacturer founded in 1946 that has specialized in ultra-precision vertical honing machines for bore finishing since entering the machine-tool business in 1973. The company's core product is the G-series honing machine line (G25, G50, G50L, G75, F25G, F50G), which uses proprietary servo-controlled stone expansion to achieve sub-micron roundness and cylindricity on bore diameters ranging from φ3 to φ100mm; flagship performance claims include 1/4 conventional honing time and 90% energy reduction versus predecessor models. Nissin also sells in-house-designed mandrels, grinding stones, and measuring nozzles, and the Smart Honing (S25GH-MT2) machine — co-developed with the University of Electro-Communications — embeds AI to automate skilled-worker grinding adjustment with a documented 86% time reduction.

In April 2025 the company reorganized into a holding-company structure with three wholly-owned operating subsidiaries: Nissin PREVO (precision components for automotive, aerospace, medical, and semiconductor end markets), Nissin ProSOL (honing machine manufacturing plus the Sagane-Kachō IoT/Smart Factory brand built on Litmus Automation's IIoT platform), and Nissin FULFIL (medical device manufacturing). The company generates revenue through direct enterprise sales of capital equipment, precision parts contract manufacturing, and after-sales service across a network of nine service locations in Japan (Kyotango, Izumo, Osaka, Nagoya, Tokyo), China (Laizhou, Shanghai), Thailand (Rayong), and India (Gurugram, opened December 2024). Its customer base is anchored by Japanese Tier 1 automotive suppliers (notably Denso, which awarded an Excellent Supplier Award in 2019) and spans 21 countries with over 2,000 installed machines. Recent strategic initiatives include G75 launch, world-first vibration-reducing jig and nano-polycrystalline cBN abrasives debuted at EMO Hannover 2023, a hydrogen gas pressure-reduction valve prototype, and a hydrogen drone fuel-cell partnership with Robodex.
