is a compact, high-performance serger designed for those who demand a factory-quality finish in a portable format. As a dedicated 1-needle, 2/3 thread machine, it excels at creating elegant, rolledhems and clean overlock edges on a vast array of fabrics. Featuring Juki's legendary industrial-grade tension and cutting systems, the MO-623 provides smooth, quiet operation that makes it a favorite for home-based designers, alteration specialists, and dedicated hobbyists.
The MO-623 is optimized for lightweight to medium-weight projects:
Professional Edge Finishing: Neatening the raw edges of blouses, skirts, and slacks to prevent fraying.
Elegant Rolled Hems: Ideal for bridal veils, evening wear, silk scarves, and cloth napkins.
Lingerie & Delicate Wear: Creating soft, low-profile seams in fine fabrics and lace.
Crafting & Decor: Finishing the edges of ruffles, table runners, and lightweight curtains
2/3 Thread Versatility: Easily switch between a 3-thread overlock for secure edge finishing and a 2-thread overlock for lightweight decorative edges (using the included converter).
Easy Rolled Hemming: Create beautiful, professional-grade rolled hems on delicate fabrics with a simple flip of a lever—no plate change required.
Industrial Cutting System: Features a heavy-duty upper and lower knife system that ensures clean, consistent trimming on everything from silk to light fleece.
Lay-In Threading: Color-coded threading paths and a simplified lay-in system take the frustration out of setup, allowing you to start sewing in seconds.
Precision Tension Dials: High-quality tension discs ensure balanced stitches across varying fabric weights and thread types.
Adjustable Stitch Length: A convenient dial on the exterior of the machine allows for instant stitch length customization (1mm to 4mm).
Retractable Knife: The upper knife can be safely deactivated and tucked away, allowing for decorative sewing without trimming the fabric.
Sewing Speed: Max. 1,500 Stitches per Minute (SPM)
The needles with your JUKI are the Organ DBx1, available on our website. This machine uses size 16×257, size 8 through 20 or 16×97. The 8700 can also use standard needles, sizes 9 through 21, universal or fabric-specific needles such as knit.
Where does the machine oil go?
A pan directly underneath the machine supplies oil to the machine with a cotton wick. Lift the machine up and over to access the oil tank while on the table. You must keep the machine’s oil level consistently at the «high» mark, either by adding more oil or draining it and refilling it as needed. If the oil pump can’t get the oil into the machine, it can cause serious problems later.
What kind of oil does this machine require?
You need a specific type, like motor oil in your car, to keep this machine running. The DDL-8700 requires JUKI New Defrix Oil No.1, equivalent to ISO VG7.
What size table can I get with this machine?
Our table has legs and is 22"w x 47"l. It includes a knee and foot pedals and a left-hand drawer for accessories.
Does the DDL 8700 make buttonholes?
No. The 8700 only does straight stitching, with a horizontal bar on the right side for a reverse stitch.
