Nagase Integrex

What Nagase Integrex does

Nagase Integrex Co., Ltd. (株式会社ナガセインテグレックス) is a privately held Japanese manufacturer of ultra-precision grinding machines and micro-fabrication machines, founded in 1950 and headquartered in Seki, Gifu Prefecture. The company designs and builds a comprehensive product portfolio spanning ultra-precision surface and profile grinding machines (SGC, SGi, SGD, SGX, ORIGIN series), high-reciprocating form grinders (SHSD, SHL, SHS, ZGP, VHG), rotary and gear grinding machines (RG, NGC), constant-pressure/position synchronized wafer grinders (NSF series), and simultaneous multi-axis nano-machines (NIC, N2C, NSL), complemented by on-machine measurement systems (NAGASE VISION, SMART 3D PROBING, SMU), dynamic balance measurement (Balance Vector/Doctor), and an AI grinding wheel surface monitoring system (GRIDE EYE).

The company's core technology stack rests on eight proprietary elemental technologies: non-contact multifaceted-constraint hydrostatic guideways, ultra-precision linear motors, synchronous six-axis nanometer motion control, ultra-precision rotary indexing (2/10000 degree accuracy), on-machine sub-micron measurement, ultra-low-vibration high-speed motion, energy-saving temperature control, and novel machining process construction, combined with an in-house structural optimization methodology (IGTARP DESIGN). This stack supports minimum machining accuracy down to 0.3 nm (equivalent to a single metal atom's diameter) and table payloads of 30 tons moved with one finger, with machines ranging from compact precision grinders to 12-meter-class double-column systems. The customer base includes precision mold and die manufacturers, optical and telescope mirror producers (Subaru Telescope, Seimei Telescope, Kanata Telescope), semiconductor and compound semiconductor manufacturers (SiC, GaN wafer processing), and industrial machinery builders across six countries (Japan, Korea, Taiwan, China, Germany, United States).

Nagase Integrex generates revenue primarily through direct hardware sales of custom-configured machines via five regional sales offices in Japan (Seki, Tokyo, Osaka, Sendai, Kyushu/Fukuoka), a Korean sales office (Uijeongbu), and overseas inquiry routing through the Chubu/Headquarters office. Pricing is custom-quoted and not publicly disclosed. Supplementary revenue streams include custom/special machine development, fee-based test and contract machining at the Technical Center and Open Laboratory, sales of peripheral equipment and consumables under the nvac brand, and the NAGASE Premium Club membership program providing technical magazines, seminars, and advance product information. Distribution is exclusively direct with no third-party resellers, supported by free test machining for equipment selection, factory tours, seminars, JIMTOF exhibition participation, and a Japanese/English corporate website. As of June 2025 the company employs 138 people across manufacturing, design, sales, and administration, holds 153 patents, and reports 50+ consecutive periods of profitability with no external funding or public listing.
