Manufacturing of industrial crown rolls
We are capable of manufacturing and repairing crown rolls such as radial crowns, taper crowns, and reverse crowns (concave).
Surface treatment: Hard chrome plating Finishing: Buff polishing, mirror polishing ■ What is a crown roll? A crown roll is a roll whose central dimension is higher than the dimensions at its ends, finished in an arc shape, referred to as a radial crown, while those finished by connecting taper shapes are called taper crowns. Conversely, a roll with higher dimensions at its ends than at its center, opposite in shape to a crown roll, is called a reverse crown. ■ Applications In addition to preventing deflection and ensuring uniform nip, crown rolls are used for various purposes, including stretching film wrinkles. ■ Precision rolls and mirror finishes are also available. We can manufacture crown rolls with a precision of less than 3μ using high-precision grinding machines, as well as ultra-mirror crown rolls with a finish of less than 0.05S using mirror polishing machines. We also offer measurement of existing roll crown values, creation of backup rolls, and repair of crown rolls.
