We produce ultra-precision tools with excellent accuracy through CAD/CAM-based tool design, 3D simulation, and CNC programming.

Products

• PCD/CBN Special Cutting Tools: We produce polycrystalline diamond (PCD) and cubic boron nitride (CBN) tools specialized for machining difficult-to-cut materials such as aluminum, composite materials, and high-hardness steel. These tools boast significantly longer lifespans and higher precision compared to conventional carbide tools, and are used in automotive parts, aircraft components, and electronic product mold processing.
• Ultra-precision Diamond Cutting Tools: We manufacture ultra-precision single-crystal tools (diamond, SiC, etc.) and possess tool manufacturing technology that satisfies under-micrometer-level edge radius and nano-level form accuracy. We have development technology for optical lens mold core turning bites (form accuracy below 50nm) and contact lens processing tools.
• Special Cutting Tools: We primarily manufacture 'Special Cutting Tools,' which are custom-made tools with special shapes tailored to customer requirements. These are used to implement advanced technology in industries requiring precision, such as semiconductors, electronics, and telecommunications.

Special Notes

• Proprietary Core Technology: We possess differentiated core technologies, including proprietary dissimilar material bonding technology and ultra-precision polishing technology capable of controlling tolerances down to 0.000001mm. Through continuous investment in R&D, we are expanding our technology portfolio and strengthening our technological leadership in the market.
• Advanced Facilities and Smart Factory System: We possess numerous advanced facilities, including 4-axis and 6-axis grinding machines boasting world-class precision, and have adopted a smart factory system to maximize production efficiency. Consistent quality is ensured through strict process and quality control in a temperature and humidity controlled 10,000 class cleanroom.
• Global Market Competitiveness: Our technology has been verified through partnerships with leading domestic conglomerates, and the excellence of our products is recognized in global markets including Asia, Europe, North America, and Central and South America. We are an export-capable company, having received the 'Million Dollar Export Tower' award in 2013.

Recruitment Information

• Main Hiring Positions: We primarily recruit for positions in cutting tool grinding (lathe milling), quality control (measurement inspection/packaging & shipping), material management, and accounting & administrative support.
• Benefits: We provide welfare benefits such as enrollment in the four major insurances, severance pay, operation of a 45-seater large commuter bus, in-house employee cafeteria, provision of individual dormitories, support for congratulatory and condolence events, and support for work-study parallel programs (4-year national engineering university).
