CNC Machining Processes for Acrylic
CNC machining is a precise method for shaping acrylic into desired forms. The main processes include:
CNC Milling
CNC milling involves using rotating cutting tools to remove material from a stationary acrylic sheet. This method is ideal for creating complex geometries and achieving high precision.
CNC Turning
In CNC turning, a single-point cutting tool removes material from a rotating acrylic workpiece. This process is suitable for producing cylindrical parts and includes operations like thread cutting and boring.
CNC Engraving
CNC engraving allows for intricate designs and patterns to be cut into acrylic surfaces. This method is often used for decorative purposes and branding.
CNC Drilling
CNC drilling creates precise holes in acrylic sheets, whether simple or complex. This process ensures clean, burr-free holes without damaging the material.
CNC Cutting
CNC cutting is a fast and efficient method for shaping acrylic sheets into specific sizes and forms, making it suitable for mass production.
