Milling of aluminum panels is carried out on a vertical cutting machine – Striebig, the difference is that during the work used disc and finger cutters V -, U-shaped and rectangular shapes.

Composite panels in the process of pre-Assembly processing are milled along the bending lines. In the production of composite panels is often required to obtain a radius bending of the material for such processing using cutters of various shapes. The selected radius of the groove (90° or 135°) enables the bending of the panels Grossbond at a right or acute angle, and a variety of forms grooves ensures a bend of the workpiece with any radius of curvature without loss of operational qualities of the material. In the manufacture of composite panels, along with disc cutters, widely used finger V-shaped or trapezoidal. Experts recommend the use of this type of cutter, since the lower base of the cutting element is not less than 3 mm, which determines the size of the base of the groove, which sets the bending radius. In addition, a small gap of 1 mm, which, one way or another, remains between the bent elements, makes it possible to slightly bend the workpiece to overcome the elasticity of aluminum composite panels and obtain a right angle. However, the use of finger mills has its own characteristics and nuances that you need to know – in particular, the time of their operation is slightly less than that of the disk as a result of lower resistance to wear. Also, the finger mill is more difficult to install correctly at a given depth of the V-shaped gap, this procedure can be performed only by an experienced milling specialist. Sometimes there is a need to manufacture their own unique copy roller for certain variants of composite panels with non-standard thickness parameters. All disc cutters for composite processing can be divided into two types: one-piece cutters and with special insert teeth. The following subspecies are integral:
