In recent years, as the market demand for precision of sheet metal parts has increased, precision sheet metal fabrication has also begun to enter the center stage of the sheet metal industry.
As a key production process in the machinery manufacturing industry, precision sheet metal parts are widely used in rail transportation equipment, precision machine tools, automobile manufacturing, medical equipment, home appliances, etc., which is an important embodiment of China's smart manufacturing. So what is the difference between precision sheet metal processing and ordinary sheet metal processing?
From the perspective of development history, precision sheet metal is actually an advanced version of sheet metal fabrication, with little change in process. The biggest difference is that precision sheet metal fabrication narrows down the precision tolerance range to less than 0.2 millimeters, while the precision of ordinary sheet metal fabrication is generally in the range of 0.2~1 millimeters.
The tolerance range of high precision sheet metal fabrication: Bending: 0-+/-0.1mm; CNC processing: 0-+/-0.1mm; Laser cutting 0-+/-0.1mm. The precision of precision sheet metal fabrication can reach 0.3~0.5mm for uncoiling and leveling, so sheet metal parts produced by laser/numerical punching/waterjet etc., and CNC bending usually meet the requirements of dimensional accuracy.
Sheet metal processing technology has gone through three stages: from the use of compasses, scissors, wooden square and other tools for marking processing, to parts processing labor-saving, uniform surface quality after processing hydraulic shears and bending machines, and then to today's CNC processing equipment, the bending angle of the processed parts can be as accurate as 0.1 °, the size of the precise to 0.1mm or even higher, no need to use the trapezoidal screws or screw threads as before! A little bit or even a few times to adjust the positioning, thus saving a lot of time and materials for the manufacturing and production of sheet metal working parts.
Precision sheet metal adopts high-precision CNC sheet metal equipment, which can realize complex processes that are difficult to do with traditional sheet metal processing. Moreover, precision sheet metal processing is equally suitable for processing products of small and large batches, and is characterized by short processing cycle, good uniformity, high processing accuracy, high degree of automation, high speed, simple and convenient operation, and high efficiency.
1. High power density of sheet metal processing: after the workpiece absorbs sheet metal processing, the temperature rises rapidly and melts or evaporates, even materials with high melting point, high hardness and brittleness can be processed with precision sheet metal processing;.
2、Sheet metal processing is convenient and flexible: robots can be used for precision sheet metal processing in harsh environments or places that are difficult for others to access.
3、Precision sheet metal processing is easy to control: it is easy to combine with precision machinery, precision measurement technology and electronic computers to realize high processing automation and achieve high processing accuracy;.
Surface treatment methods for precision sheet metal parts processing: galvanization, chrome plating, painting, electrostatic powder coating.
Most of the precision sheet metal parts seen on the market have textures on their surfaces, which are obtained after surface treatment, and can effectively protect the sheet metal parts from external factors, corrosion, denaturation and other effects.
