Precision Levelers for Laser Cut & Stamped Parts

Saw blades before and after leveling with a roller leveler — Precision Flatness for Laser Job Shops & Sheet Metal Applications

For stress-relieved and flat sheet metal parts and sheet metal from a thickness starting at 0.1 mm. Allowing for subsequent processes such as welding, bending and forming to be more accurate, consistent and efficient. Without the need for reworking parts!

ARKU offers you an extensive portofilo of roller levelers for flattening and stress-relieving sheet metal parts after laser cutting and punching. The machine can also flatten the entire sheet metal prior to cutting as well. Different machine models are used depending on the material specifications and flatness requirements. Material type, geometry, quantity and part dimensions all influence the choice of the ideal precision leveler. Always with one goal in mind: to precisely flatten and stress-relieve your laser cut and punched parts.

Here you will find an overview of our precision levelers.

More about parts handling

Why do stamped and laser cut parts need leveling after cutting?

Stamped and laser-cut sheet metal parts often develop internal stresses due to heat input and mechanical deformation during cutting. These stresses can lead to distortion, uneven surfaces, and dimensional inaccuracies. Precision leveling machines remove these stresses through controlled roller bending, resulting in flat, stable parts that are ready for downstream processes like welding or bending.

What thickness ranges can leveling machines handle for laser and punched parts?

Modern leveling machines are designed to process a wide range of material thicknesses—from thin sheet metal below 1 mm (0.039 inches) up to heavy plates exceeding 25 mm (1 inch), depending on the machine type. Different systems are optimized for specific applications, ensuring consistent flatness across both delicate precision parts and thicker industrial components.

How do leveling machines improve production efficiency for sheet metal parts?

Leveling machines significantly increase efficiency by reducing manual straightening and minimizing rework. Parts that might take minutes or even hours to straighten manually can be leveled in seconds using automated systems. This leads to faster throughput, lower labor costs, and more consistent production quality across high-volume manufacturing environments.

What challenges do laser cut and punched parts create in automated assembly?

Laser cut and punched parts that are not properly leveled can cause misalignment, poor fit, and interruptions in automated assembly systems. Even small deviations in flatness can lead to positioning errors in robotic handling or welding processes. Leveling ensures uniform part geometry, which improves reliability and efficiency in automated production environments.
