Machine Condition & Testing

Every used Juki MB-373 undergoes a rigorous mechanical refurbishment protocol to guarantee production readiness:

• Stitch & Knot Audit: The thread-fray prevention and knotting mechanism are tested to ensure buttons do not loosen after production.

• Clamp & Feed Inspection: The button clamp is verified for precise centering to prevent needle breakage and ensure uniform attachment.

• Cam & Timing Calibration: The stitch-shape cam is inspected for wear, ensuring accurate transitions between 2-hole and 4-hole patterns.
