Product Description
For this one, the supplied compatibility is broader than the recent Cupid parts, so Lejiang YJ-65 should be the primary machine target, while Messer, Taking and Octa should only be mentioned as compatible 65mm machines if that interchangeability has actually been
Keep your 65mm cloth cutting machine blade sharp with this G71 Grinder Assembly Set, designed for compatible Lejiang YJ-65 series mini electric round and octagonal blade cloth cutting machines.
This complete blade sharpening assembly mounts beside the cutting blade and allows the operator to sharpen the blade during machine operation. The spring-loaded mechanism brings the abrasive grinding wheel into contact with the rotating blade to help restore the cutting edge.
A properly sharpened blade can help the machine cut fabric more cleanly and reduce problems such as pulled threads, fabric dragging and uneven cutting. This makes the grinder assembly useful for regular maintenance in tailoring, garment production and fabric cutting work.
Pack Quantity: 1 Set
Part Number: G71
Alternative Part Number: G69
Important: Please compare the shape, mounting arrangement and existing grinder assembly before purchasing. If your machine is not a Lejiang YJ-65 or a verified compatible 65mm cutter, confirm the fit before ordering.
What Is a G71 Grinder Assembly?
The G71 grinder assembly is the blade-sharpening mechanism fitted near the cutting blade of a compatible 65mm electric cloth cutting machine.
Instead of removing the blade for every sharpening operation, the built-in grinder allows the cutting edge to be refreshed while the machine is being used.
The assembly uses a spring-loaded mechanism to bring the abrasive wheel against the rotating blade. This helps maintain the blade edge during repeated fabric-cutting work.

Lejiang YJ-65
The G71 grinder assembly is designed for the Lejiang YJ-65 series mini electric cloth cutting machines.
It mounts near the cutting blade and provides an integrated sharpening mechanism for maintaining the blade edge during fabric cutting.
If you are replacing an existing G71 or G69 grinder assembly, compare the mounting arrangement and grinder-wheel position before purchasing.
65mm Mini Electric Cloth Cutting Machines
This assembly is intended for compatible 65mm round and octagonal blade mini cloth cutting machines.
However, 65mm blade size alone does not guarantee compatibility. Different manufacturers can use different grinder housings and mounting arrangements, so compare your existing assembly before ordering.
G71 / G69 PART NUMBER
This product is identified as G71, with G69 supplied as an alternative part number.
If your existing grinder assembly is marked G71 or G69, compare the physical assembly before replacement to ensure the mounting configuration matches.
WHY IS A BLADE GRINDER IMPORTANT?
A sharp cutting blade is important for clean and consistent fabric cutting.
As the blade becomes dull, you may notice:
- Reduced cutting efficiency
- Increased fabric resistance
- Pulled or frayed threads
- Difficulty cutting multiple layers
- Uneven cutting
- More operator effort
- Fabric getting caught during cutting
The built-in grinder helps maintain the blade edge during regular machine use, reducing the need for frequent manual blade sharpening.
HOW THE G71 GRINDER WORKS
The grinder assembly uses a spring-loaded mechanism to move the abrasive wheel toward the rotating blade.
When the sharpening mechanism is engaged, the grinding wheel contacts the blade edge and removes a small amount of material to refresh the cutting edge.
The sharpening process should be controlled carefully. Excessive grinding can unnecessarily reduce blade life or affect blade geometry.
SUITABLE FOR
This replacement grinder assembly is useful for:
- Tailors
- Garment factories
- Textile workshops
- Boutique production units
- Fabric cutting operators
- Upholstery workers
- Leather workers
- Garment machinery technicians
- Cloth cutting machine repair shops
It is especially useful for machines that are used frequently and require regular blade sharpening.
SIGNS YOUR GRINDER ASSEMBLY MAY NEED REPLACEMENT
Inspect the grinder assembly if:
- The sharpening wheel no longer contacts the blade correctly
- The push mechanism feels loose
- The spring mechanism does not return properly
- The grinding wheel is excessively worn
- The grinder housing is damaged
- The blade cannot be sharpened evenly
- The assembly has become loose near the cutter head
Also inspect the blade itself. A badly damaged or excessively worn blade may need replacement rather than repeated sharpening.
HOW TO USE THE G71 GRINDER ASSEMBLY
- Switch on the cloth cutting machine according to the manufacturer’s operating procedure.
- Keep your hands clear of the rotating blade.
- Position the grinder mechanism as designed on the cutter head.
- Engage the spring-loaded sharpening mechanism.
- Allow the abrasive wheel to contact the blade briefly.
- Release the sharpening mechanism.
- Check the blade condition and cutting performance.
- Repeat only when additional sharpening is necessary.
Do not hold the grinding wheel against the blade continuously. Excessive grinding can generate unnecessary heat and shorten blade life.
If you have individual product pages for verified 65mm compatible machines, those can be linked from the compatibility section. Don’t create internal links to machines merely because they use a 65mm blade.
FREQUENTLY ASKED QUESTIONS
What is a G71 grinder assembly?
A G71 grinder assembly is a built-in blade sharpening mechanism for compatible 65mm electric cloth cutting machines. It uses an abrasive grinding wheel and spring-loaded mechanism to refresh the cutting blade during operation.
Is this G71 grinder compatible with Lejiang YJ-65?
Yes. This grinder assembly is designed for the Lejiang YJ-65 series mini electric cloth cutting machines.
Is G71 the same as G69?
G71 is the supplied part number, while G69 is listed as an alternative part number for this grinder assembly. Compare the physical mounting arrangement before replacing an existing assembly.
Can this grinder sharpen the blade while the machine is operating?
Yes. The assembly is designed to sharpen the rotating blade through its spring-loaded grinding mechanism. Use the sharpening function briefly and avoid keeping the abrasive wheel against the blade continuously.
Does a sharp blade improve fabric cutting?
Yes. A properly maintained blade can cut fabric more efficiently and help reduce pulling, fraying and uneven cutting. Blade sharpness is especially important when cutting multiple fabric layers.
Can this grinder assembly be used on any 65mm cutter?
No. A 65mm blade diameter alone does not guarantee that the grinder assembly will fit. Compare the mounting arrangement and existing grinder housing before purchasing.
Is this compatible with Messer 65mm machines?
Compatibility should be verified against the existing grinder assembly before purchase. Do not rely on the 65mm blade size alone.
Is this compatible with Taking 65mm machines?
Compatibility should be verified before purchase by comparing the existing grinder assembly and mounting arrangement.
Is this compatible with Octa 65mm cutters?
Verify the physical mounting configuration before purchase. The 65mm blade size by itself does not confirm compatibility.
How many pieces are included?
The package contains 1 complete grinder assembly set.
When should I replace the grinder assembly?
Replace it when the grinding wheel is excessively worn, the spring mechanism no longer works correctly, the housing is damaged or the assembly cannot maintain proper contact with the blade.
