A Beginner’s Guide to Using a Rolling Mill

Whether you’re new to jewellery making or looking to upgrade your toolkit, the rolling mill is one of the most versatile pieces of equipment you can own. From shaping sheet metal to forming wire, it opens up a host of creative possibilities.

What is a Rolling Mill?

A rolling mill is a tool used in metalworking and jewellery making to compress and reshape metal. The typical jewellery rolling mill uses two hardened steel rollers that flatten or reshape metal by applying consistent pressure.

A rolling mill transforms metal into different gauges and even changes its shape. For example, passing a round disc through the rollers will flatten it into an oval — a key technique in many jewellery designs.

How To Use A Rolling Mill

If using a rolling mill is something you’re new to, then don’t worry. We’ve collated all our tips on the rolling mill process and the best way to use it in this handy video.

How to Roll Sheet

Rolling sheet metal is one of the most common uses for a rolling mill. Before you begin, it’s important to make sure the metal has been annealed, cleaned and dried. Once prepared, adjust the roller gap so the sheet can just about pass through, then reduce the gap slightly to apply pressure. Hold the sheet with one hand and turn the handle with the other, feeding the metal through the rollers. After the first pass, check the thickness and repeat as needed until you reach the desired gauge, annealing between stages if necessary.

Creating Ovals

To create oval shapes, take a metal disc and feed it through the rollers as you would with sheet. This compresses the metal and begins to stretch it into an oval. Measure the length and thickness, and repeat the process — always feeding it in the same direction to further elongate the shape.

Shaping Wire

When shaping wire, many rolling mills feature grooves that allow you to form square or D-shaped profiles. The wire should be properly prepared and cleaned before rolling. Feed it into the grooves and turn the handle, then rotate the wire between passes to shape it evenly. This technique is ideal for creating more structured or decorative wires used in settings and frames.

Benefits of Using a Rolling Mill

Here are just a few reasons why a rolling mill can become one of your most-used tools:

• Versatility: Shape both wire and sheet metal, and even imprint textures using pattern plates.
• Efficiency: Save time and money by reducing metal yourself instead of ordering multiple gauges.
• Precision: Get the exact thickness and shape needed for your project.
• Creativity: Use with texture sheets or organic materials to emboss patterns.
• Durability: With proper care, a rolling mill can last decades.
• Professional Results: Achieve clean, consistent finishes that elevate your work.

Best Practices When Using a Rolling Mills

When using a rolling mill, consider the following best practice hints and tips:

• Always work with dry metal to prevent rust and marks.
• Roll gradually, reducing thickness in stages to avoid cracking.
• Keep your mill clean and oiled to extend its lifespan.
• Store properly, using a dust cover or cloth to protect the rollers.

A rolling mill may be an investment, but it’s one that pays dividends in creativity and control. Whether you’re texturing, thinning or shaping, it unlocks techniques that would be difficult or impossible by hand. So if you’re ready to expand your jewellery-making skills, a rolling mill could be your next essential tool.
