Aircraft rolls are long, extremely specialized sheet metal rolling machines designed largely for one specific purpose: to roll the metallic “skin” of the forward edge of aircraft wings in the correct contoured shape to properly generate lift while in flight. The shape of most wing edges will change in thickness and angle from the tip to where it joins the fuselage, so rolling the metal for the skin requires a machine that can alter the geometry of its rolls during the rolling process, unlike a simple plate roll that creates the same diameter across the length of the rolled material.

While at first glance the machine resembles a press brake with its tall, moveable ram-like structure on top, it is actually a pyramid-style three-roll machine. All three rolls can change position, with the top roll being vertically adjustable and the two bottom rolls being horizontally adjustable in relation to each other. The positions of the left and right ends of each roll are adjusted independently, allowing them to be taken out of parallel with each other in order to roll the desired contour. While traditionally called aircraft rolls or leading-edge rolls because of their main use, these machines can also be referred to as contour rolls due to their ability to produce variety of different types of tapered parts, such as cones, and do so without additional tooling. The ANERKA Aircraft Roll revolution to fill the void left when Farnham and similar aircraft rolls ceased production, Anerka stepped up and introduced the ANERKA VMR Series rolls, machines that perform the same function, but are designed with powerful, unique features that improve the rolling process for both ease and accuracy.

Designed and engineered in the TURKEY, ANERKA’s aircraft rolls are built to stay in production for decades, and offer the simplest, fastest and most precise wing rolling currently available for the aviation fabrication industry. They are extremely powerful and can even roll titanium-alloyed sheets with multiple radii to form perfect cylindrical, tapered or hyperbolic shapes. ANERKA VMR Series aircraft rolls are specially designed to overcome the ultra-high yield point of titanium but are also ideal for a wide range of other materials. With a body constructed of stress-relieved high yield steel, the ANERKA VMR Series machine also features induction hardened, chrome coated, ground carbon steel rolls that are seated in bronze roller bushings. All rolls are driven by AC motors and helical gear boxes with cardan shafts. These adjustable  peed aircraft rolls feature digital readouts and offer an optional NC control unit. Like all ANERKA machines, safety is a priority, and the VMR Series includes electrical and mechanical protection against overloads and features an emergency stop cable running around the machine.
