Key Technical Specifications
The standard operational parameters for the MO-6700 series include:
- Maximum Sewing Speed: Up to 7,000 stitches per minute for rapid production.
- Needle System: Uses high-durability DC27 needles.
- Needle Bar Stroke: Measured at 24.5 mm to cleanly handle multiple fabric layers.
- Stitch Adjustments: Easily customizable stitch sizing managed via a push-button mechanism inside the side cover. [1, 2, 3, 4, 5, 6]
Core Variations & Sub-Models
The series was released in structural variations designed to solve distinct manufacturing constraints:
- Juki MO-6700S: The classic, established high-speed configuration. It utilizes a traditional fully-lubricated mechanical setup that provides massive cost-effectiveness for bulk fabric processing.
- Juki MO-6700DA: The premium Semi-Dry-Head variation. This model applies advanced dry-head technology to the needle bar and upper looper mechanisms. By removing lubrication from parts causing oil splashes, it completely eliminates oil stains on garments, saving companies time on spot-cleaning. [1, 2, 3, 4, 5, 6]
Recommended Sub-Models for Purchasing
- Juki MO-6714DA (4-Thread Overlock):
- Features a two-needle, four-thread configuration designed primarily for stretchable fabrics, knitwear, and general cut-and-sewn apparel.
- Provides excellent seam flexibility and elasticity, perfect for items like T-shirts, activewear, and underwear.
- Juki MO-6716DA (5-Thread Safety Stitch):
- Features a two-needle, five-thread setup which incorporates a dedicated safety lockstitch chain alongside the overlock seam.
- Highly recommended for heavy-weight materials and woven goods, such as denim, uniforms, or workwear, ensuring seams do not fray or rip under structural tension. [1, 2, 3, 4]
Notable Operational Benefits
- Multi-Material Capability: The feed locus and tension discs handle everything from delicate ladies' swimwear and camisoles to 4-ply heavy denim without requiring severe adjustments.
- Preventative Engineering: Fully equipped with adjusting provisions that minimize fabric puckering or slippage on tricky modern synthetic textiles.
- Motor Setup: Can be retrofitted from old-style clutch motors to energy-efficient servo direct-drive motors to decrease energy usage and reduce workplace noise. [1, 2, 3, 4, 5]
Please note that while the original baseline MO-6700S series has been largely discontinued by the manufacturer to make room for newer generation models like the MO-6800, both new and refurbished MO-6700 models remain highly sought after on industrial marketplaces due to their long lifespans and easy parts availability.
