Decision tree
Do you nail delicate MDF or wide profiles daily?
Yes → lean NN700 for plate clamping and gap-free corners.
Is budget the main constraint with wood/PS volume?
Yes → NN500 covers most studio throughput needs.
Need stored profiles for mixed SKUs?
Both store profiles — NN700 when CNC repeatability is critical.
Export frames with zero visible corner gap?
Yes → NN700 plate clamping; NN500 when occasional MDF is acceptable with tuning.
FAQ
Can NN500 handle MDF?
Yes, with proper nail sizing and clamp settings. NN700 is preferred when corner gap control on MDF is critical.
What is gap-free corner compression on NN700?
Plate clamping holds the moulding under pressure while V-nails drive — reducing visible gaps on MDF and wide profiles versus standard pneumatic cycles.
When does NN500 beat NN700 on ROI?
Wood and PS daily batches under ~600 frames with no recurring MDF gap QC issues — lower capital and faster commissioning.
Which ships faster for a new studio?
NN500 typically has a shorter commissioning path; NN700 adds CNC calibration time.
