I don't know if you have ever come across that customers have certain requirements on flatness and parallelism when purchasing 2A12 aluminum plate. How does the manufacturer of 2A12 aluminum plate control the flatness and parallelism of 2A12 aluminum plate?Next small make up to give you a specific introduction.

Before I introduce how to control the flatness and parallelism of 2A12 aluminum plate, I would like to introduce to you what flatness and parallelism are, so that you can understand the following content more easily.

Refers to the parallelism of two planes, or two parallel lines, refers to a plane (P) relative to another plane error (side) parallel to the maximum allowable value.Where the reference line or plane is evaluated, and the line may be the straight part of a test sample or a linear trajectory, and the plane may be part of a trajectory forming a plane or a test sample.

Flatness refers to the deviation of concave-convex height on the surface of 2A12 aluminum plate.It can be understood as the shape error in the form and position error.

In order to control the flatness and parallelism of 2A12 aluminum plate, it is generally recommended to design a fixture to ensure its value.

1. First, make a steel plate the same as the 2A12 aluminum plate workpiece, put it on the 2A12 aluminum plate workpiece, press the steel plate and start processing.

2, the steel plate is either through the vacuum suction cup, or their own double-sided adhesive with thin material.Each light cut, 90° shoulder milling, below the auxiliary multiple front supports on top of the points.

3, the tool to use soft material tool, two sides of the processing to remove the margin to keep consistent, otherwise one side to more not easy to deformation.Control distortion one is to always remove the margin on both sides, then program path optimization each layer path direction will be better.

4. 2A12 aluminum plate needs heat treatment to remove internal stress, rough machining, reprocessing and finishing.The point effect is good. The blank may be processed directly by freezing sucker after stress treatment.

This is how to control the flatness and parallelism of 2A12 aluminum plate. If you need 2A12 aluminum plate, please contact us.
