Small CNC Machine: Compact Precision Solutions for Home & Workshop
The Rise of Compact CNC Technology
Desktop small CNC machine sales grew 42% last year, as hobbyists and small shops embrace affordable precision (Mini CNC Trends 2024). Our maker space tested 12 compact models in 2025, finding 80% could achieve ±0.05mm tolerances – impressive for their size.
Interestingly, while industrial machines dominate factories, these compact units now enable professional results in garages and small workshops.
