What does XKY Framing do?

XKY Framing (Yiwu Xinkuangyuan Machinery Co., Ltd.) designs and manufactures industrial framing machinery for picture frame, mirror, and cabinet door producers worldwide. Our product range includes fully automatic quad-corner underpinners (NN300), pneumatic and CNC underpinners (NN400–NN700), industrial stack cutting saws (NC500, NC600), dust-free miter saws (CT300), and pneumatic aluminium saws (CT400), plus a full range of V-nail fasteners.

Where is XKY Framing located?

XKY Framing is based at 77 Gexian Road, Yiwu City, Zhejiang Province, China — in the heart of the world's manufacturing hub. We supply framing machinery to customers globally.

What machines does XKY Framing manufacture?

XKY manufactures four main product categories: (1) Auto Underpinners — including the NN300 fully automatic quad-corner system (1,000+ frames/hour) and the NN400/NN500/NN600/NN700 pneumatic and CNC underpinners for joining 45° and 90° miter joints using V-nails. (2) Auto Cutting — including the NC600 industrial high-capacity stack saw and NC500 fully automatic stack cutting saw for double-miter cutting of MDF and wrapped profiles. (3) Frame Cutting — including the CT300 dust-free precision miter saw and CT400 pneumatic aluminium saw. (4) V-Nail Fasteners — compatible with all standard underpinner brands, available in soft, general-purpose, and hardwood grades from 7mm to 15mm.

How fast is the XKY NN300 automatic underpinner?

The XKY NN300 (SL-NN300) Fully Automatic Quad-Corner Underpinner joins all four corners of a frame simultaneously with a cycle time of 2–3 seconds, achieving over 1,000 joined frames per hour — up to 400% faster than manual operation. It is ideal for high-volume picture frame, mirror, and cabinet door production.

What is the difference between the NC500 and NC600 cutting saws?

The NC500 is a fully automatic stack cutting saw with a proprietary mold-based clamping system, best for complex or irregular moulding profiles up to 21.5" wide. The NC600 Industrial High-Capacity Stack Saw adds a 100mm (4") wide cutting range, anti-chip Three-Cut Mode, and zero-waste mirror-cut mode, boosting efficiency by 300–500% over manual saws. The NC600 is the flagship choice for large-scale laminated MDF and wrapped gesso frame factories.

Does XKY offer after-sales support and installation?

Yes. XKY provides a comprehensive service package: remote technical diagnostics via WhatsApp, WeChat, or Teams; full HD video tutorial libraries; on-site installation and operator training; a preventative maintenance program; 24-hour urgent support; and express spare parts dispatch (DHL/FedEx/UPS) from our Yiwu warehouse. Genuine spare parts are also available through xkyframing.com.

Are XKY V-nails compatible with other brands of underpinners?
