How Mirror-Finish CNC Machining Works

Steps Involved

Achieving a mirror finish is a multi-step process that may include:

• Precision Machining: Initial shaping of the workpiece.
• Grinding: Removing material to achieve a flatter surface.
• Polishing: Using fine abrasives to create a reflective surface.
• Buffing: Final touches to enhance the gloss and smoothness.

Considerations for Moulds

When it comes to machining moulds, mirror-finish techniques offer significant benefits:

• Injection Moulds: They require high surface quality to produce smooth parts.
• Die Casting Moulds: Enhanced surfaces minimize defects and improve product quality.

Choosing the right materials and processes is crucial when designing moulds for mirror finish applications.
