Underpinner in Framing Machine: Underpinners drive V-nails into moulding joints at precise angles — choose pneumatic models for shop throughput or CNC plate-clamping units for mixed MDF and coated profiles.
XKY framing machines cover the full industrial workflow — from stick cutting and quad-corner joining to back-panel finishing and automated production lines. Every model is CE-certified, built in Yiwu since 2004, and engineered as a performance alternative to European OEM equipment.
