From the point of view of the development process, precision sheet metal is actually an advanced version of sheet metal processing, the process changes little, the biggest difference is that precision sheet metal processing precision tolerance range is reduced to below 0.2 mm, while the accuracy of ordinary sheet metal processing is generally between 0.2 and 1 mm.
High precision sheet metal processing tolerance range: bending: 0-+/-0.1mm; CNC machining: 0-+/-0.1mm; Laser cutting 0-+/-0.1mm. Precision sheet metal processing of unwinding and leveling accuracy can reach 0.3 ~ 0.5mm, so the laser/digital punching/water knife cutting, CNC bending production of sheet metal parts can usually meet the dimensional accuracy requirements.
Sheet metal processing process goes through 3 stages: From the use of compasses, scissors, wood square feet and other tools for marking processing, to parts processing, hydraulic shears and bending machines with uniform surface quality after processing, and then to today's CNC processing equipment, the bending Angle of processed parts can be accurate to 0.1°, and the size can be accurate to 0.1mm or even higher. It is no longer necessary to adjust the positioning with trapezoidal screw or thread a little or even several times as before, which saves a lot of time and materials for sheet metal workpiece manufacturing.

What are the heat treatment methods of CNC machining
Heat treatment process generally includes heating, insulation, cooling three processes, sometimes only heating and cooling two processes. These processes are interconnected and uninterruptible. Metal heat treatment process can be roughly divided into integral heat treatment, surface heat treatment and chemical heat treatment three categories.
What are the common surface treatments?
The appearance of the workpiece is inseparable from the design, color, material and process, of which the surface treatment process is the most direct reflection of the appearance of the product. Surface treatment can improve the appearance, texture, function and other aspects of product performance.
