Our precision levelers for flame cut parts (plasma and oxyfuel cut parts) and heavy plates ensure low-stress and flat parts and plates up to a thickness of 60 mm (2.36 inches). They effortlessly level large and thick parts and plates, as well as rough plates with rust and dirt.
ARKU Precision Levelers for Thick Metal Parts & Plates
ARKU offers you an extensive portfolio of roller levelers for flattening and stress-relieving metal plate and thick parts after flame (plasma and oxyfuel) cutting. The machine can also flatten the entire metal plates 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 flame cut parts.
Here you will find an overview of our precision levelers.
FlatMaster® 55
The FlatMaster® 55 ensures the best flatness and stress-relieve results for sheet metal and plate of a thickness between 0.02" up to 0.60" (0.6 up to 15 mm). Its servo-hydraulic adjustment system enables precise flatness and repeatable results. Whether in machinery construction, contract manufacturing, vehicle production, or agricultural equipment manufacturing, the FlatMaster® can level a wide array of parts, sheets & plates.
FlatMaster® 88
The FlatMaster® 88 delivers ideal flatness and stress-relieve results for sheet metal and heavy plate from 0.04" up to 1.10" (1.0 up to 28 mm) thick. Typical applications include machinery and plant engineering, steel mills, the construction equipment industry, contract manufacturing, agricultural machinery, and vehicle production.
FlatMaster® 120
The FlatMaster® 120 is ideal for flattening and stress-relieving predominately heavy plate and parts from 0.06" up to 1.57" (1.5 up to 40 mm) thick. Typical applications include machinery and plant engineering, steel mills, the construction equipment industry, contract manufacturing, agricultural machinery, and vehicle production.
FlatMaster® 140
The FlatMaster® 140 ensures the best flatness and stress-relieving results for parts and heavy plates from 0.08" up to 1.77" (2.0 up to 45 mm) thick. Typical applications include machinery and plant engineering, steel mills, the construction equipment industry, contract manufacturing, agricultural machinery, vehicle and shipbuilding, as well as the defense industry.
FlatMaster® 180
The FlatMaster® 180 is ideal for leveling very large and very thick parts and plates with a thickness from 0.08" up to 1.77" (4.0 up to 60 mm) thick. Typical applications include machinery and plant engineering, steel mills, contract manufacturing, the construction equipment and agricultural machinery industries, as well as vehicle manufacturing, shipbuilding, and the defense industry.
PlateMaster® L-XXL for leveling large metal plates
The PlateMaster® was specially developed to level large and thick metal plates. Ideal for processing large and thick plates with heavy rust or dirt on them since the machine is resistant to dirt. Specifically developed for heavy plate processors, this machine reliably levels even heavily rusted plate material.
Advantages of the ARKU Precision Levelers
Global market leader
Put your trust in the market leader when it comes to precision levelers. ARKU has over 60 years of experience.
Precise leveling results
ARKU precision levelers deliver the best straightening results. Unique to the market is the servo-hydraulic leveling gap control for the FlatMaster® series. This feature enables precision down to a hundredth of a millimeter.
Robust machines
The hydraulic overload protection protects the machine's drive and leveling unit and makes it nearly indestructible. Safeguarding the machine completely from any wrong inputs. Thus making ARKU precision levelers the longest lasting roller levelers on the market.
Easy cleaning & maintenace
Cleaning and maintenance is easy and quick thanks to the quick-change feature that provides access to the leveling rollers and backup rollers.
