Lower Counter Knife for Cupid 110mm & 125mm Cutter

Keep your round knife cloth cutting machine cutting smoothly with this Lower Counter Knife for Cupid 110mm & 125mm Round Knife Cloth Cutting Machines. It works as the stationary lower blade that meets the rotating upper knife to create a clean shearing action.

This replacement lower knife is designed for Cupid 110mm and 125mm round knife cutters and can also suit compatible rotary cutting machines from brands such as Taking, Detech, Lejiang, and Octa when the mounting dimensions match. Lower knives are an important part of the cutting system because the upper and lower cutting edges work together during operation.

What You Get

• 1 × Lower Counter Knife / Stationary Blade
• Flat mounting arm with fixing hole
• Suitable replacement for worn or damaged lower knives
• Designed for use with compatible 110mm and 125mm round knife cutters

Why Replace the Lower Counter Knife?

A worn lower knife can affect the contact between the stationary and rotating blades. This may contribute to rough cutting, fabric dragging, bunching, or inconsistent cutting performance.

A properly fitted counter knife helps maintain firm contact with the rotating blade. This is particularly useful when cutting multiple layers of fabric for garment production, tailoring, upholstery, and textile work.

Key Features

Precision stationary shearing:
The lower knife works against the upper rotary blade in a scissor-like cutting action for cleaner fabric separation.

Wear-resistant cutting edge:
The hardened cutting edge is designed to maintain effective blade contact during regular cutting work.

Helps reduce fabric drag:
The stationary knife supports the cutting area and helps prevent the bottom fabric layer from shifting or bunching beneath the blade.

Flat mounting profile:
The flat arm and mounting hole allow straightforward positioning on the cutter’s base housing.

Direct replacement design:
Useful when servicing a round knife cutter with a worn, damaged, or ineffective lower knife.

Machine Compatibility

Important: Compatibility with similar brands depends on the lower knife mounting shape, hole position, and dimensions. Please verify the shape and measurements of your existing part before purchasing.

Best Fabric Types

This lower counter knife is suitable for round knife cutting applications involving common apparel and textile materials, including:

• Cotton
• Denim
• Polyester
• Rayon
• Linen
• Silk
• Wool
• Knitted fabrics

• Upholstery materials
• Non-woven textiles
• Light leather

The actual cutting capacity depends on the machine, upper blade condition, fabric construction, and number of layers being cut.

How To Use

1. Switch off and unplug the cloth cutting machine.
2. Remove the worn lower counter knife according to the machine’s service procedure.
3. Clean lint and fabric debris from the mounting area.
4. Position the replacement knife in the original mounting location.
5. Align the mounting hole and secure the knife firmly.
6. Check the position of the lower knife against the rotating upper blade.
7. Rotate or test the cutter carefully before returning it to production use.

Always handle the upper and lower cutting edges carefully. Round knife machines use very sharp cutting components.

When Should You Replace the Lower Knife?

Replace the lower knife when its cutting edge becomes worn, damaged, or no longer maintains proper contact with the upper rotary blade. Regular inspection is useful when the cutter is used frequently for production work. Manufacturers of round knife machines also specify lower-knife maintenance or replacement as part of blade servicing.

4. FREQUENTLY ASKED QUESTIONS

What is a lower counter knife on a round knife cutting machine?

A lower counter knife is the stationary cutting edge positioned beneath the rotating round or octagonal blade. The two edges work together to create a shearing action. It helps the machine separate fabric cleanly and can support consistent cutting when the blade alignment and mounting are correct.

Is this lower knife compatible with Cupid 110mm and 125mm machines?

Yes. This lower counter knife is specified for Cupid 110mm and 125mm round knife cloth cutting machines. It may also fit compatible Taking, Detech, Lejiang, or Octa machines when the mounting shape, hole position, and measurements match the original part.

Can a worn lower knife affect fabric cutting?

Yes. A worn or damaged lower knife can reduce effective contact with the rotating blade and may contribute to rough cutting, fabric dragging, or inconsistent shearing. Replacing the worn stationary blade can help restore proper blade interaction when the rest of the cutting system is correctly adjusted.

Is this the same as a round knife blade?

No. This is the lower stationary counter knife, not the rotating upper round knife. It is installed on the lower section of the cutting mechanism and works against the moving blade during fabric cutting.

Can I use it on another 110mm or 125mm round knife cutter?

Possibly, but size alone does not guarantee compatibility. The mounting hole, blade position, shape, and dimensions should match the original lower knife. Please verify the shape and measurements of your existing part before purchasing.
