Precision machined sheet metal parts are metal parts manufactured through high-precision machining technology. The following is a detailed description and explanation of their structure, characteristics, application scenarios and machining methods:
1. Structure
Precision machined sheet metal parts are usually made of metal sheets, which can be stainless steel, aluminum alloy, copper and other metal materials. These sheet metal parts have complex shapes and structures and may contain multiple process steps such as cutting, bending, welding, and so on. Their structural features include, but are not limited to:
Uniform or gradual changes in wall thickness, avoiding sudden changes in wall thickness to minimize cracks and other defects.
The intersections of adjacent surfaces are often made into rounded corners to improve the strength of the part and prevent cracking.
The shape is simplified with a straight profile and a reduced concave-convex structure on the inner wall to facilitate manufacturing and processing.
