Corrective leveling machine for straightening metal sheets and parts

Roll diameter: 30-60mm
Leveling thickness: 3-10mm
Leveling width: 50-1000mm

A precision leveler is a machine used in metalworking to flatten or straighten metal sheets or coils with high precision. It works by passing the material through a series of rollers or leveling heads that apply pressure to specific areas, adjusting the curvature of the metal to achieve a flat or uniform surface. The process continues until the desired level of flatness or straightness is achieved.

Features

Dual Roller Drive: Features a servo motor coupled with a high-precision gearbox, ensuring smooth and stable operation of the leveling rollers.

CNC Closed-Loop Control
Utilizes a full CNC system with real-time feedback via displacement sensors to maintain constant gap accuracy between rollers.

Enhanced Gear System
The gears are optimally designed for even distribution of power to the rollers, featuring fine grinding and heat treatment for reduced noise and increased durability.

Robust Roller Construction
Includes 23 high-strength alloy steel rollers, each hardened to enhance mechanical properties and extend operational life.

Advanced Roller Pitch Technology
Employs an unequal roller pitch arrangement to optimize stress relief during the leveling process.

Individual Roller Drive
Each roller is driven independently by a cardan shaft, providing precise control and enhanced performance.

Superior Bearing System
Rollers are supported by needle bearings, sealed to prevent contamination and designed for extended maintenance intervals.

Applications

Designed for high-precision flattening, this leveler excels with a range of materials including aluminum, stainless steel, carbon steel, and copper plates. It is especially effective in applications requiring precise flatness such as automotive parts, aerospace structures, high-speed rail components, and metal furniture and electrical enclosures.
