The metal wire drawing process is to grind the material, mechanically move back and forth and chemically corrode the metal surface, so that the surface of the workpiece can get a layer of macroscopic lines with uniform thickness distribution. Mass production high demand CNC service online
The brushed treatment can make the metal surface obtain a non-mirror-like metallic luster, and has a very strong decorative effect. It can be used on many kinds of metal products such as stainless steel, aluminum, copper and iron. The drawing can be divided into manual drawing and mechanical drawing. Common mechanical wire drawing includes flat-press abrasive belt wire drawing, non-woven roller brush wire drawing, wide abrasive belt wire drawing and centerless grinding wire drawing, etc. The editor will first show you how they are drawn
01 flat pressure abrasive belt drawing
Flat-pressure abrasive belt drawing is a very common drawing method. The workpiece is fixed on the mold, and the grinding belt runs at high speed. There is a pneumatically controlled pressing block that can move up and down on the back of the abrasive belt. After pressing down, the abrasive belt is attached Wire drawing is carried out on the surface of the metal being processed. Mass production high demand CNC service online
Flat-press abrasive belt drawing is suitable for small-area surfaces that require flat drawing, such as drawing of digital camera casings, mobile phone casings, etc. The lines produced by this kind of drawing are usually continuous straight silk lines.
In addition to the automatic flat wire drawing machine, there is also a type of mechanical equipment that needs to be manually operated. The principle is similar, and the editor will also show you.
02 Brushed non-woven roller
Non-woven roller brush drawing means that the workpiece is conveyed by the conveyor belt through the non-woven roller brush, and the roller brush rotates at a high speed to draw the surface of the workpiece. There are two methods of roller brush vibration and roller brush non-vibration during wire drawing, and at the same time, different processing speeds are used to produce lines of different lengths.

Non-woven roller brush drawing is suitable for large-area drawing. The drawing surface can have a certain curved surface, or even a small boss such as a text logo. It is often used in notebook alloy panels, keyboard panels, mobile phone LCD frames, battery covers and camera protection panels.
03 Wide abrasive belt drawing
Wide abrasive belt drawing is the most traditional drawing method. The abrasive belt rotates at high speed, and the plate is polished and drawn by the conveyor belt through the abrasive belt. Usually, stainless steel plate, aluminum alloy and other plates are made into drawing semi-finished products for further production. The product.
Wide abrasive belt drawing is suitable for flat drawing, especially suitable for plate processing. It is often used for drawing stainless steel elevator door panels, stainless steel counters, aluminum alloy cabinets, etc. The lines drawn in this way are usually very thin and short, commonly known as snow patterns.
04 Centerless grinding wire drawing
Centerless wire drawing is a centerless grinding method for wire drawing, and the grinding products used are non-woven wire wheels or abrasive belts. Mass production high demand CNC service online
Centerless wire drawing is suitable for wire drawing processing of round tubular workpieces, such as handles and handles. The wires drawn in this way are usually short wires, and the length of the wires is related to the rotation speed of the workpiece, the rotation speed of the grinding product and the grinding product itself.
Different wire drawing methods will produce different wire textures. Generally, wire drawing textures can be divided into straight grain, random grain, corrugated grain and swirl grain. Mass production high demand CNC service online
