What are the machining processes for aluminum forgings?

1、 Preparation stage

Drawing and Process Analysis:

Analyze the mechanical processing procedures and required process equipment based on product drawings and technical requirements.

Determine the machining method, machining sequence, machining allowance, cutting parameters, etc.

Preparation of raw materials:

Select suitable aluminum alloy billets based on design drawings and process requirements.

Preparation work such as cutting and heating of the blank to meet subsequent processing requirements.

2、 Rough machining stage

Remove excess:

By using machining methods such as milling and turning, the excess on the surface of the billet is removed to approximate the final shape and size of the product.

Basic shape forming:

According to the drawing requirements, the basic shape and contour of the product are formed through mechanical processing methods.

3、 Semi precision machining stage

Further refinement:

On the basis of rough machining, further adjust the shape and size of the product to improve machining accuracy.

Chamfering and deburring:

Chamfering the edges of the product to remove burrs and burrs generated during mechanical processing.

4、 Precision machining stage

Reaching the final size and shape:

By using high-precision machining methods such as grinding, polishing, etc., the product is made to meet the final size and shape requirements.

Surface smoothness treatment:

Smooth the surface of the product to improve its appearance and surface quality.

5、 Inspection and Testing

Size and shape inspection:

Use measuring tools to inspect the size and shape of the product to ensure compliance with design requirements.

Surface quality inspection:

Check the surface quality of the product, including smoothness, absence of cracks, inclusions, and other defects.

Performance testing:

According to product requirements, conduct necessary performance tests such as hardness testing, tensile testing, etc.

In summary, the mechanical processing of aluminum forgings is a complex and delicate process that requires strict control of the processing quality and accuracy of each step to ensure that the quality and performance of the final product meet the requirements.
