Wire drawing is a surface treatment method that forms lines on the surface of the workpiece by grinding the product to achieve a decorative effect. Since wire drawing can reflect the texture of metal materials, it has been loved by more and more users and is increasingly widely used.
The abrasive belt drawing process is a very important processing step, which is of great significance to the quality and use effect, but sometimes we find that the belt drawing effect is uneven.
In fact, there are three main factors that affect the effect of abrasive belt drawing:
01 Abrasive belt grit
For the same type of abrasive belt, the coarser the grit, the deeper the wire drawing line. 120#-400# is the grit used for belt wire drawing process.
02 Abrasive belt workpiece material
For workpieces of different materials, even if the same abrasive belt, the same machine, and the same parameters are used, the results are different. If you want to get a very obvious brushed effect on the surface of a stainless steel workpiece, you will generally choose a coarser grain, a harder backing, and a sharper mineral sand.
03 Abrasive Belt Wiredrawing Method
Wiredrawing methods are mainly divided into manual wiredrawing and mechanical wiredrawing. Manual wiredrawing is for small workpieces. This kind of wiredrawing has low efficiency and unstable line effect, so the mainstream is mechanical wiredrawing.
Mechanical wiredrawing is mainly divided into flat-press wiredrawing, contact wiredrawing, and non-woven roller wiredrawing.
The flat-press wiredrawing line is continuous and long, and there cannot be any convex points on the wiredrawing surface;
Contact wiredrawing is point and line contact, not surface contact;
Non-woven roller wiredrawing is suitable for processing some curved workpieces, generates less heat, and belongs to cold processing.
The above are the reasons that affect the effect of abrasive belt drawing. Wire drawing is a physical surface treatment process, which is a permanent, destructive and irreversible process. Therefore, in order to better ensure the wire drawing effect, it is necessary to pay special attention to some processing details.
