JACK N9-D AI-Powered Direct Drive Computerized Electronic Lockstitch Buttonhole Machine (25mm x 4mm) - Complete Setup, Table, Stand Included

The Jack N9-D is the next-generation AI-powered electronic lockstitch buttonhole machine — the direct successor to the industry-standard JK-T1790 series. Built on Jack's newest intelligent platform, the N9-D features AI-driven material adaptation that automatically detects fabric thickness and density, then adjusts tension, speed, and stitch parameters in real time to deliver perfect buttonholes on every garment, every time — eliminating manual setup adjustments between fabric types.

Powered by a direct drive servo motor with built-in stepper motors for fabric feed, needle bar, and knife operation, the N9-D produces clean, precise buttonholes at speeds up to 4,200 stitches per minute. The semi-dry head design eliminates oil staining, while the integrated touchscreen control panel provides 31 pre-installed buttonhole patterns expandable to 500 user-defined patterns via USB import.

Ideal for shirts and blouses, dress shirts, polo shirts, trousers, lightweight jackets, uniforms, and any garment production requiring fast, repeatable, precision buttonholes across a variety of fabric types — without the constant parameter tweaking that older machines demand.
