CNC router 3020/3018 enclosure

CNC 3020 Soundproof Enclosure

This enclosure was designed specifically for the CNC 3020 to reduce noise, contain chips, and improve overall workshop cleanliness during machining operations.

The enclosure uses a double-wall construction consisting of an outer 15 mm OSB shell and an inner 3 mm HDF lining. The cavity between the walls is filled with 30 mm RE80 acoustic foam, helping to absorb sound and reduce vibrations generated by the spindle and cutting process.

The front door features double glazing made from two 4 mm plexiglass panels separated by an air gap, providing improved acoustic insulation while maintaining excellent visibility of the machine.

Features

• Simple construction using commonly available materials

Materials

• Planed timber frame (30 × 48 mm)

• 15 mm OSB 3 boards

Notes

The enclosure was designed with a focus on noise reduction rather than complete soundproofing. Actual noise reduction depends on spindle speed, cutting parameters, workpiece material, and the performance of the dust extraction system.

Built-in vacuum ports allow connection of both dust extraction and enclosure ventilation systems if required.

Tested with 800W spindle
