Used Chien Wei Grinding Machines for Sale

About Chien Wei Machines

Chien Wei Precise Technology Co., Ltd. is a Taiwan-based manufacturer headquartered in Kaohsiung. The company’s official product range covers CNC high-precision jig grinders, CNC vertical grinding machines, precision milling grinding machines, internal/external gear grinders, measuring instruments, molds, and precision components.

Unlike brands that mainly focus on general-purpose turning or milling, Chien Wei is most relevant to buyers looking for specialized grinding and measurement-oriented production capability. Its jig grinders are designed for high-precision flat surfaces, complex shapes, and round holes, while its vertical grinding machines support precision mold and component work. The company’s gear grinding development is also linked to robotics-related gear production, including applications involving involute and cycloidal profiles.

Used Chien Wei machines may attract buyers in mold and die manufacturing, optics, IC packaging, precision components, reducer parts, and high-accuracy grinding operations. On the second-hand market, interest is usually model-specific, because buyers often need to match machine travel, spindle speed, control system, dressing capability, measuring functions, and grinding application to a defined production requirement.
