Of course, aluminum profile manufacturers have higher technical standards for aluminum profile production and processing machinery, equipment and managers. Among them, the flatness of the profile plane is one of the specified quality standards. The plane specification of aluminum profiles is required in GB5237, the specification for aluminum alloy profiles engineering and building profiles. The plane gap in the product specification error of aluminum profile processing manufacturers is the specification for the plane.
The product plane clearance from the aluminum profile manufacturer refers to: place a 25mm long ruler against the concave surface of the profile along the total width, and accurately measure the large gap between the ruler and the profile concave surface (F1), this value (F1 ) is the plane gap on the total width of the profile at random 25mm; put the ruler whose length exceeds the total width of the profile against the concave surface of the profile, and accurately measure the large gap between the ruler and the concave surface of the profile (F)
The plane clearance is also known as the uneven plane, and the lower the clearance value, the flatter it is. The technical index of the plane clearance is the specification of the section, not the specification of the shape (shape tolerance). So how is the overall appearance required? The specification requires the degree of bending and twisting. If it is 0, the aluminum profile of the 50 series casement window shows that there is no deformation. Naturally, this is also the result of the basic theory. The fact Undoubtedly there is a transformation. So is there a specific term to describe the unevenness of the overall commodity? Yes, that is the flatness.
The flatness of the aluminum profile manufacturer in the production and processing stage refers to the error of the relative idealized plane of the relative height of the macroeconomic convex and concave of the silicon wafer. The tolerance zone is the area in the middle of two parallel planes separated by the dimensional tolerance value t. The plane of the product is uneven, put it on the reference point, the bottom point is on the reference point, and the distance between the higher and the reference point is the flatness. Relative to the plane clearance, bending degree, and twisting degree mentioned earlier, the usual understanding is that the flatness is a comprehensive reflection of the plane clearance, bending degree, and twisting degree.
