Guillotine Blade Sharpening Service
To ensure top cutting quality and to avoid waste, paper guillotine blades should be sharpened regularly. The frequency of guillotine blade sharpening service depends upon the operational cycle, workload of the blades, and the blade material.
When using a blunt paper guillotine blade, several issues can arise that negatively affect both the quality of the cut and operational efficiency:
1. Frayed or Torn Edges
• A dull blade rips or crushes the paper instead of slicing cleanly.
• Results in rough, uneven, or feathered edges, especially on thicker stacks or coated papers.
2. Inconsistent or Crooked Cuts
• A blunt blade struggles to maintain precision, leading to misaligned or skewed cuts.
• Can affect product uniformity, especially in high-tolerance jobs (e.g., packaging, print finishing).
3. Paper Jamming or Shifting
• The blade may drag rather than slice, causing the stack to move or jam during cutting.
• Increases the risk of damaging paper or wasting stock.
4. Increased Machine Stress
• A dull blade puts more strain on the guillotine’s motor and mechanics.
• Leads to faster wear and potential breakdown of machine components.
5. Safety Hazards
• Operators may apply more force or make repeated cuts, increasing the risk of accidents.
• Blade bounce or unpredictable motion can also occur with dull edges.
6. Reduced Productivity
• More time is spent aligning, re-cutting, or fixing poor-quality cuts.
• Frequent rework lowers throughput and efficiency.
7. Wasted Material
• Poor cuts lead to scrap, especially problematic with expensive or specialty paper stocks.
To achieve faultless quality of cut paper it is important to regularly check guillotine blade sharpening state. As professional sharpening industrial services grinders we can restore the blade edge perfectly flat and precise.
Our Guillotine Blade Sharpening Process
During the first stage of sharpening a paper cutting guillotine blade, our engineers accurately remove all damage and grooves from a paper cutting guillotine blade. We have an extended database of paper cutting guillotine blade bevels, thus ensuring the required and precise positioning of the blade throughout the sharpening service. This enables us to take off only irregular areas (less than half of a millimetre or even less for tungsten carbide blades). Hence after the service, a guillotine blade has almost the same thickness and can sustain more grinding and sharpening cycles.
Then, to remove burr after machine grinding we use an ‘oil stone’. We apply that stage only to Standard Steel and HSS guillotine blades. In general, we noticed, that Tungsten Carbide Blades are very sharp immediately after machine sharpening.
However, even if the blade is sharp, it can feel dull because the sharp edge has been pushed off to the side. To improve the geometry and texture of a surface we hone guillotine blades. To do this, we use a honing machine with 5 very fine grinding wheels. It is important, that although knife honing is an essential step, it will not repair even the smallest chip.
Finally, we check any invisible chips in the ready sharpened guillotine blade with a light paper. Our high quality sharpening service restores the cutting performance of your blades, offering a fast turnaround with a friendly, experienced service.
