MAT-03505000 Fixed Knife for Juki MO-6716S-FF6-50H Sewing Machine Cutter Parts

The MAT-03505000 Fixed Knife is a replacement cutting component designed for the Juki MO-6716S-FF6-50H industrial overlock sewing machine.

Installed in the fabric trimming system, this fixed knife works together with the moving knife to cut excess fabric during sewing. A sharp and correctly fitted fixed knife helps produce clean fabric edges, stable seam quality and efficient continuous production.

Please send your complete machine model, old knife photos and required quantity before ordering. Our team will help confirm compatibility and provide a complete quotation with suitable delivery options.

The fabric trimming system is an important part of an industrial overlock sewing machine. During operation, the fixed knife and moving knife work together to trim the edge of the fabric before the overlock stitches are formed.

MAT-03505000 is a fixed knife supplied for use with the Juki MO-6716S-FF6-50H machine configuration. It provides a stable cutting edge against which the moving knife performs the trimming action.

After continuous use, the knife edge may become blunt, chipped or uneven. This can cause incomplete trimming, rough fabric edges, thread pulling, increased fabric waste or inconsistent seam appearance.

Replacing the worn fixed knife helps restore clean trimming performance and supports smoother machine operation. It is a practical cutter part for garment factories, sewing workshops, maintenance departments and industrial sewing machine spare parts distributors.

The fixed knife remains in a stable position inside the cutting mechanism while the moving knife performs repeated cutting movements.

When fabric passes through the sewing area, the two knife edges meet and trim the excess fabric along the seam. This allows the overlock stitching system to form a cleaner and more consistent finished edge.

The cutting performance depends on the condition, position and alignment of both knives. A worn fixed knife may reduce cutting efficiency even when the moving knife is still functioning normally.

Installing the correct fixed knife and adjusting it properly helps maintain a smooth trimming action, reduce fabric pulling and improve the appearance of the finished seam.

1. The knife should be inspected when the fabric edge is no longer cut completely.
2. Replacement may be required if uncut fibers remain after sewing.
3. A rough, torn or uneven fabric edge can indicate that the knife has become blunt or damaged.
4. Visible chips, dents, deformation or excessive wear on the cutting edge are signs that the knife should be replaced.
5. The knife mechanism should also be checked when abnormal noise occurs during trimming.
6. If a new moving knife does not restore the cutting result, the fixed knife and knife alignment should be inspected.

1. Turn off the machine and disconnect the power supply before replacing the knife.
2. Remove the worn fixed knife carefully and clean the installation area.
3. Check the moving knife for wear, cracks or deformation.
4. Install the replacement fixed knife in the correct position.
5. Adjust the contact position between the fixed knife and moving knife according to the machine requirements.
6. Rotate the machine manually to confirm that the knives move without abnormal impact.
7. Test the cutting result using waste fabric before restarting regular production.
8. Installation should be completed by an experienced sewing machine technician when possible.
