CNC Machining

Computer Numerical Control (CNC) machining is one of the most prevalent methods in precision machining. It utilizes pre-programmed software to control the movement of machinery, enabling highly accurate cuts and shapes. This automation minimizes human error and ensures consistency across production batches.

Electrical Discharge Machining (EDM)

EDM is a non-traditional machining process that uses electrical discharges to remove material from a workpiece. This method is particularly effective for creating intricate shapes and complex cavities, making it invaluable for the production of molds and dies.

Laser Machining

Laser machining employs focused laser beams to cut, engrave, or etch materials with extreme precision. This technique is particularly useful for thin materials and complex designs, offering high-speed processing with minimal thermal distortion.

Waterjet Cutting

Waterjet cutting utilizes high-pressure water to cut through materials, making it ideal for applications requiring clean edges and minimal heat-affected zones. This method is non-intrusive and can work with a wide range of materials.
