Application
Corrugated slitter scorer knife is used for slitting and trimming of corrugated paper board, and used with grinding wheel.
Description
As a leading manufacturer in the market, we launched cemented carbide corrugated slitter scorer knives in the early 2000s. Today, these products are globally renowned. Many of the world's leading original equipment manufacturers (OEMs) of corrugated board equipment choose these blades.
The corrugated slitter scorer knives are manufactured from the source, utilizing premium powder raw materials sourced from top suppliers worldwide. The process includes spray granulation, automatic pressing, high-temperature and high-pressure sintering, and CNC precision grinding to form the blades. Every batch undergoes wear resistance simulation testing to ensure consistent quality. Large stocks are maintained for blades compatible with common corrugated board machine models, enabling quick delivery. For custom requirements or problems related to corrugated board slitting, please seek professional solutions.
Frequently Asked Questions
What causes burr edges on corrugated board during slitting?
Burr edges are typically caused by dull knife edges, shallow slitting depth, or too much starch glue stuck on the knives. Low rotary linear speed can also contribute to this issue.
How can I solve the problem of subside edges?
Subside edges are often the result of an improper slitting depth setting that is too deep. Adjusting the depth and ensuring the corrugated board moisture content is not too high can help.
What is the importance of the grinding wheel in resharpening?
It is crucial to check that the bevel setting of resharpening wheels is correct to ensure the cutting edge of the knives is ground to a sharp point for clean cuts.
Why does the corrugated board edge burst during the process?
Bursting often occurs if the moisture content of the corrugated board is too high or if the board is too soft. Maintaining proper tension during board transfer is also vital.
How do cleaning pads affect the slitting quality?
Cleaning pads must have adequate grease. If they lack grease, starch glues from the board may stick to the knives, leading to poor cutting quality.
How is the quality and durability of the blades ensured?
Every batch of knives undergoes CNC precision grinding and rigorous wear resistance simulation testing before shipping to ensure consistent and high-level performance.
