Material Selection Method for Sheet Metal Machining

Create Time: 20-12-2017

Ⅰ. What are the material selection methods for sheet metal machining?


Sheet metal machining includes traditional laser cutting and cutting, cold stamping production and processing, cold bending forming, etc. and the main parameters of the processing technology, as well as the main parameters of various cold stamping die design and processing technology, and various principles and control methods of machinery and equipment, and also contains new stamping die technology and new technologies. After cold-drawing of the sheet metal, the thickness of the sheet metal parts can be changed to a more fixed thickness. As everyone knows, sheet metal processing parts for different purposes must be selected from different sheet metal raw materials.


Ⅱ. Sheet metal machining raw materials mainly include the following two categories


1. Stainless steel sheet

(1) Cold rolled steel sheet. Cold-rolled steel plate is mainly a kind of steel plate that is controlled by the room temperature, which is lower than the work hardening temperature. The steel plate that has undergone cold rolling has a relatively smooth surface and a well-proportioned thickness. It doesn't require a lot of cost and is very easy to form. It can be wiped off with paint or electroplating process to solve it, so that the scope of application of steel plate can be expanded.


(2) Hot rolled steel plate: This kind of steel plate sheet metal machining is mainly to produce a rough rolled steel plate after heating the blooming plate or the cast billet, and then dephosphorizing. Under normal circumstances, there will be a slight error in the thickness of the hot-rolled steel plate, and there may be a problem of blanking during the specific solution period. The hot rolled steel sheet metal machining technology is mainly used in the production and manufacturing of parts of machinery and equipment such as cars, roads, bridges, and ships.


2. Galvanized steel sheet. Galvanized steel sheet is mainly hot-dip galvanized on the surface of the steel sheet. Under normal circumstances, the thickness of the hot-dip galvanized layer of the steel plate must be controlled above 10μm, so as to avoid damage such as corrosion on the surface of the steel plate, and it is mainly used in parts with higher requirements for corrosion resistance.
