I have been working with printing and packaging companies' maintenance departments for 40 years. Our company's policies and procedures continue transitioning to keep up with the ever-changing requirements, solutions, and challenges to get the job done. Depending on the type of business industry you serve, there will be projects that have "The Murphy's Law" trophy. Let's face it, our communication process can get lost down the supply chain, and when something goes wrong everyone goes into PANIC mode.

During the lifetime of your equipment you will need to replace your harden rolls more than a few times depending on your operational hours and applications. People often ask me, “How do I get the best value and extended life on my replacement?”   One of the biggest keys to harden rolls’ longevity is the hardness scale and effective depth on the roller construction.  The Rockwell hardness on the slitters must be at least 2-4 points less than the roller construction hardness. The average hardness scale th...
