Verdict
The ONA QX4 holds a spec advantage in this comparison, but the right choice depends on your shop's priorities. If the ONA QX4's strengths in areas like Z Travel and max workpiece weight align with your work, it's the clear pick. The Sodick AG40L may still win on dealer proximity, existing tooling compatibility, or specific features that matter most to your applications. Request quotes from both dealers and, if possible, run your actual parts on each machine before deciding.
