From superabrasive tools to high-performance thermal materials — from tool designers to carbon-based composite innovators.
Nanjing CuFeng Mechanical & Electrical Technology Co., Ltd.
Located in Jiangbei New Area, Nanjing
CuFeng (ToSpike) specializes in carbon-based interface engineering, spanning from atomic-level active fusion bonding to a carbon-based composite platform on sp³–sp² hybrid bonding.
Besides superabrasive tools (Diamond/CBN), work also covers thermal management, structural strength, and electromagnetic protection for semiconductor manufacturing, aerospace, AI computing, and new energy systems.
A decade-plus of expertise in vacuum interface metallurgy and active fusion bonding, applying microscopic process control to extreme machining of cast metals, CFRP, and hard brittle materials, and extending into custom tools and functional materials.
Design principles from superabrasive tools now drive high-performance thermal management, shifting from precision tools toward a functional materials platform, with continued exploration of carbon structures in properties, interfaces, and endogenous dynamics.
Continued materials and process development for high-power-density thermal management, new energy, and solid-state batteries.
New technology, new heights — from superabrasive tools to a carbon-based composite platform.
