What Samchully Machinery does
Samchully Machinery Co., Ltd., headquartered in Incheon, South Korea, is a manufacturer of workholding solutions for CNC turning centers and machining centers. Founded in October 1975 as Samwoo Machinery and renamed Samchully Machinery in October 2001, the company designs and produces power chucks, hydraulic rotary cylinders, NC rotary tables, machine vises, steady rests, special chucks, manual chucks, and precision tooling systems. Its technology is rooted in mechanical and hydraulic engineering, with proprietary innovations including a Zero-Backlash Roller Gear Cam (2015), Precision Clamping System Zero-Position/CSP (2020), 5-axis Stamping Vise/SCV (2024), Jaw-Forming Hollow Hydraulic Chuck/JB (2025), Air Vise/APV with a claimed World First Dual-Boost System (2025), and Hydrostatic Bearing Cylinder/SDN (2026). The company also offers its own NeoCon-S and NeoCon-T controllers for NC rotary tables, extending vertical scope into control electronics.
The company's revenue model is hardware sales of CNC workholding equipment and replacement accessories (soft jaws, hard jaws, collets, adaptor plates) to OEM machine builders and manufacturing end-users. Distribution combines a wholly-owned US subsidiary (Samchully Workholding, Inc., Lake Forest, California, established January 2010), a Mexico entity, a China Technical Center (established August 2015), and a network of regional distributors across North America, South America, Europe, Asia, Africa, and Oceania. Pricing is inquiry-based and not publicly disclosed, reflecting negotiated OEM and distributor contracts. Major OEM customers include DN Solutions, Hyundai WIA, Haas Automation, DMG MORI, ACE Designers, LMW, Biglia, SMEC, LEADWELL, and Alex-tech, with supply relationships dating as far back as 1986 (Daewoo/Doosan) and 1993 (KIA Machinery/Hyundai WIA).
The company operates manufacturing facilities at its Namdong Industrial Complex headquarters in Incheon and at the Changwon factory in Gyeongsangnam-do, with a new Changwon Center completed in December 2025. It holds ISO 9001 (2000), CE (2001), JIS (1980), NEP Mark, Single PPM, R-Mark, and KCS certifications. The company remains privately held and family-controlled, led by CEO Jae-Won Seo with Chairman Hong-seok Seo (awarded the Industrial Service Medal in October 2023). It received the 10 Million Dollar Export Tower from the Korea International Trade Association in 2019, recognizing export milestones rather than total revenue.
