Precision Cylindrical Roll Grinding

Roll Technology is an industry leader in precision cylindrical roll grinding services for web-based converting rolls. Over the past 45 years, we have earned a reputation worldwide for the quality and accuracy of our roll grinding services, supported by superior customer service.

What is Roll Grinding?

Accurate, precision roll grinding is a critical factor in the manufacturing and finishing of precision rolls for web-based converting operations. Exact diameter sizes and concentricity are crucial to the efficient operation of converting equipment and the quality of the finished product.

Roll Grinding Process & Services

At Roll Technology, we provide expert precision grinding for all types of rolls, including coating rolls, heat transfer rolls, calender rolls, laminating rolls, anvil rolls, slitted rolls, and custom designed web process rolls.

Our roll grinding process and capabilities include:

Roll concentricity — Precision grinding to your exact specifications and the tightest tolerances. We will grind the roll to meet the total indicated runout (TIR) in your specifications.
Precision crowned rolls — Using conventional and computer-controlled CNC crowning equipment, we offer a range of crowning options, including parabolic, radial, straight- tapered, and custom - both concave and convex crowns.
Hardened steel roll refinishing — Precision grinding of anvil wolfs (hardened 52100 and D2 tool steel) to prepare for clean-up and refinishing.

When to Have Your Rolls Reground

Rolls wear gradually, so the signs often show up in your product before anyone checks the roll. It is time to have a roll measured and reground when you see:

Uneven coat weights or gauge variation across the web
Wrinkling, tracking problems, or uneven tension
Vibration or chatter at production speed
Visible wear, scoring, or a degraded surface finish

Send us your roll drawing or current measurements, and we will tell you whether grinding alone will restore it or whether it needs refinishing.

FAQs

What is roll grinding?

Roll grinding restores or sets a roll's exact diameter, concentricity, and surface. For web converting rolls, that precision is what keeps equipment running efficiently and product quality consistent.

What types of rolls do you grind?

We grind coating rolls, heat transfer rolls, calender rolls, laminating rolls, anvil rolls, slitted rolls, and custom web process rolls.

What crown profiles can you grind?

Using conventional and CNC crowning equipment, we grind parabolic, radial, straight-tapered, and custom crowns, both concave and convex.

Can you grind hardened steel rolls?

Yes. We precision grind hardened anvil rolls in 52100 and D2 tool steel to prepare them for clean-up and refinishing.

How long has Roll Technology been grinding rolls?

Roll Technology has provided precision roll grinding services for 45 years.
