Best Small CNC Machines: Compare Models & Features for Precision Work
The Compact CNC Market Boom
Desktop small CNC machine sales surged 65% in 2023, as makers and small shops embrace affordable precision (Mini Maker Trends 2024). Our workshop tested 18 models in 2025, finding even sub-$2,000 units now rival industrial accuracy for small parts.
Interestingly, while these compact machines occupy just 2’x3′ spaces, many can achieve ±0.05mm tolerances – unthinkable a decade ago.
Top 5 Compact CNC Models Compared
Shapeoko 5: Best All-Around
Starting at $1,699, this router handles aluminum with 500x500mm work area and excellent community support.
