Specialized Machining Services

Micro-machining and EDM are specialized manufacturing processes designed for ultra-fine features, tight tolerances, and difficult materials. Micro-machining enables micron-level accuracy using extremely small tools, while EDM and micro-EDM remove material through controlled electrical discharges without mechanical stress.

Evolution of CNC Technology

This article traces the evolution of CNC (Computer Numerical Control) technology from manual machining and early numerical control systems to modern smart CNC platforms. It covers key milestones including punch-tape NC machines, the rise of digital CNC programming, CAD/CAM integration, multi-axis and high-speed machining
