Machine Leveller Overview
What Is a Machine Leveller
People sometimes call this tool a “machine leveller” or a “leveling machine.” Both names mean the same thing. This tool helps make materials flat and smooth, especially metal strips and sheets. You use a leveling machine by putting the material through rollers. The rollers bend and stretch the metal. This makes it flat and takes away bends or waves.
A machine leveller is different from other flattening tools. It can change the shape of metal so it stays flat after you take it out. You can move the backup roller flights up and down by themselves. This lets you control how the metal bends.
Leveler backup roller flights can move up and down on their own. This helps you bend the work rolls just how you want.
Here is a table that shows how a machine leveller is different from other flattening tools:
Feature | Machine Leveler | Other Flattening Equipment |
|---|---|---|
Deformation Type | Plastically bends material to achieve flatness | May not achieve plastic deformation |
Roll Configuration | Work roll bends material over its radius | Backup rolls prevent deflection of work rolls |
Vertically adjustable backup roller flights | Fixed backup rolls | |
Length Differential Issues | Can eliminate coil set and crossbow | May not address edge wave and center buckle issues |
There are rules for using a leveling machine in factories. These rules cover how well it works, how safe it is, how it affects the environment, and how to take care of it. The rules help you make sure the machine does a good job and is safe to use.
Main Functions
The main job of a machine leveller is to fix flatness problems in metal strips and sheets. It helps get rid of bends, waves, and other surface problems. The machine works by moving the metal through rollers that are not in a straight line. The rollers bend and stretch the metal. This helps take away bumps and stress inside the metal.
You can use a leveling machine on many kinds of metal. It works on thin steel sheets, aluminum strips, copper foils, and even special metal mixes. When you use a sheet metal leveler, you get these good things:
You fix flatness problems in thin metal sheets.
You lower leftover stress in metal strips.
You can guess how flat the strip will be after you finish.
Leveling machines use both pulling and bending at the same time. This helps make metal sheets flat and easy to use for other jobs. You can change the machine to fit the thickness, width, and strength of the metal you want to level.
Some leveling machines today use smart technology. For example, some have laser systems that check and fix the surface while the machine is working. Others use sensors and robots to work faster and better. These new tools help you get great results with less work.
How a Leveling Machine Works
Roller Leveling Process
When you use a leveling machine, you count on the roller leveling process to make metal sheets flat and smooth. The machine leveller pushes the metal through several rollers. These rollers bend and stretch the metal a little at a time. The metal goes through bends that get smaller each time. This helps the metal become flat again by beating its yield strength.
Roller leveling is a bending method. You use it to make sheet metal flat and lower leftover stress. The rollers bend and then bend the metal back, which takes away bumps and makes the surface smooth.
After leveling, the metal changes in a few ways. The yield strength goes up by about 14–18%. Elongation gets lower by 1–3%. The hardening exponent drops by 15%. These changes make the metal stronger and harder to bend again.
How the rollers are set up matters a lot for the machine to work well. You start with main rollers that straighten the coil. Then, extra rollers fix the coil more and take out any last curves. You can move these extra rollers for better leveling. This setup gives you more accuracy, longer roller life, and lets you work with many coil types and sizes.
Roller leveling uses bending and bending back to fix flatness.
The process makes yield strength higher and elongation lower.
You can move rollers for better results and longer use.
The roller setup lets you work with many kinds of metal coils.

How to Use a Leveling Machine
Step-by-Step Guide
You can get good results with a leveling machine if you follow some easy steps. Here is a simple guide to help you use a leveling machine:
Feed the Material: First, use the forward button on the control panel. Put your metal strip or sheet into the rollers. If the material stays curved, the top rollers need more pressure. Turn the handwheel in the same way and try again.
Adjust Pressure: If the material bends too much the other way, the top rollers have too much pressure. Turn the handwheel back and test a new strip. You want the pressure just right so the material comes out flat.
Set Automation: When you get the right flatness, move the “L”-shaped sensor at the exit. Turn the knob to automatic mode. The machine will keep working and leveling as the sensor touches the material.
Safety First: Always read the owner’s manual before you start. Make sure warning signs are easy to see. Keep your hands and body away from moving parts. Never use broken equipment.
