⦿ What is CNC and Its Role in Mold MachiningCNC (Computer Numerical Control) is a machining method that precisely controls machine movements through computer programming. In mold manufacturing, CNC primarily handles the shaping and cutting of components such as mold cores, sliders, and electrodes, serving as the core process in the entire manufacturing workflow.

⦿ CNC Machining Process for Molds
The typical CNC machining process for molds includes the following steps:

• Design drawings and program creation (CAM)

• Rough cutting to remove excess material

• Finishing to meet surface and tolerance requirements

• EDM reservation and fine trimming of mating surfaces

The entire process tests not only the rigidity of the equipment but also the operator's experience and attention to detail.

⦿ Why CNC Machining Quality Affects Mold Trial Results
High-quality CNC machining ensures accurate mold structure, reducing the need for polishing, rework, and multiple mold trials. Errors in CNC machining can cause poor mold fits, product deformation, and injection molding defects.
