Plane requirements for special industrial aluminum profiles

With the development of industrial aluminum profiles, the quality requirements for industrial aluminum profiles are also increasing. The flatness of the aluminum profile plane is one of the requested quality objectives.

The industrial aluminum profile plane request has rules in the aluminum alloy profile construction profile specification GB/T6892-2015, and the plane gap in the commodity scale error is the request for the plane.

The plane gap means: a 25 mm long ruler is placed on the concave surface of the profile along the width direction, and the maximum gap value between the ruler and the concave surface of the profile is measured, which is a plane gap of the profile width of 25 mm; the length is larger than the profile The ruler of the width rests on the concave surface of the profile and measures the maximum gap between the ruler and the concave surface of the profile, which is the plane clearance of the profile over its entire width.

The plane gap is also the flat surface we generally say, and the smaller the gap value, the flatter. The goal of a planar void is the scale request of the section, not the shape (shape) request. So how is the shape of the whole ruled? In the specification, the degree of curvature and twisting are regular.

Flatness refers to the error of the microscopic height and height of the substrate relative to the ambition plane. The public service zone is the area between two parallel planes separated by a common duty value t. The plane of the product is uneven, placed on the reference plane, the lowest point is on the reference plane, and the highest point to the reference plane spacing is the flatness. Compared with the plane gap, bending degree and twisting degree mentioned above, the general understanding is that the flatness is the inductive expression of the plane gap, the bending degree and the twisting degree.

Nowadays, the industrial profiles on the market, due to the particularity of the use, are flat on the merchandise drawings, and make higher demands on the quality of the products of the profiles. The products of Jiangyin Aluminum Profile Factory include aluminum template series products and computer board series products, and the flatness ranges from 0.4mm to 1.0mm.

It should be mentioned that the original flatness of the product is mostly used for the precision request of machining, and the use of the kneading industrial aluminum profile is rare. The delivery length of goods with flatness request is generally shorter than the construction of industrial aluminum profiles, such as computer board profiles, the delivery length is 362mm.
