285 F And The Roll Grinding Variable

Grinding At Ambient Temperatures Leads To Production Variation  

All manufacturers are concerned with their production efficiency and quality. But are you aware of everything that impacts these critical components of your operation?

Especially in plastics manufacturing – but also in the production of film products, composites and laminated products – the temperature at which your rolls operate is a crucial variable in proper roll grinding.

For rolls that operate at high temperatures – generally from 285 to 600 F – hot or 3D roll grinding is an essential practice that leads to producing uniform, quality products. 

How Does 3D Grinding Work?

Also known as hot grinding, 3D roll grinding is another method that accounts for the changing composition of your rolls when run under hot temperatures. Your rolls expand under such intense temperatures, but they expand at different rates in various areas on your roll due to the metallurgy and manufacturing process. That is why grinding your rolls at a temperature other than that at which they operate leaves room for error and imperfection.

3D roll grinding essentially works by heating rolls to their operating temperature and then performing precision measurements and grinding. It ensures that your rolls are perfect for running in your production process.

The Benefits Of 3D Grinding

In the 3D precision grinding process, measurements are taken to confirm that roll tolerances, shape and profile are precise. Such accuracy and precision mitigates the risks of roll defects, translating to production efficiency and quality that ensure greater uniformity and better products.

In addition, because rolls are precise when run at their operating temperature, roll maintenance is needed far less frequently, increasing your production uptime and impacting your bottom line.
