The difference between the abrasive belt and the nylon wheel
If the abrasive product used for wire drawing is improperly selected, it has a great influence on the effect of drawing or pulling. Different abrasive products have different drawing effects. Different particle sizes of the same grinding product will also produce different drawing effects. Since the grinding products directly act on the drawing surface, it is quite important to select suitable grinding products and quality.
1) About the belt
An important factor in wire drawing is the surface consistency of the product. There are two aspects of consistency: one is that the surface of the workpiece should be evenly drawn, and the other is that the consistency of the drawing effect between different workpieces is better, and the difference is small. For the surface drawing to be uniform, the current belt effect depends on the quality of the belt itself. For the consistency of the drawing effect between different workpieces, the ordinary belt is much worse. Because the abrasive belt itself is lossy during the wire drawing process, specifically, the abrasive material is sharp and sharp at the beginning of drawing, and the drawing line is deep, but the wire is soon blunt, and the drawn line is relatively shallow. In this way, the same batch of brushed workpieces will have a significant difference between the product drawn in front and the surface of the product being drawn behind.

2) Nylon wheel (drawing wheel, gray wheel, ash, fiber wheel, non-woven grinding wheel) nylon wheel is made of high quality mineral sand and fine fiber. The utility model has the advantages that the brushed surface can have a certain curvature, and the drawing effect is consistent before and after, and the phenomenon that the texture is not uniform or the drawing pattern is disordered due to the loss of the abrasive product during the operation. The nylon wheel structure has an anti-clogging function. This is due to its own advantages of good adhesion and good heat dissipation. Such an advantage is advantageous for the loss of heat during drawing, and is advantageous for wire drawing processing of a large area surface. The nylon wheel developed by our company has many advantages such as sand, no hair, no blackening. It is an effect that is not easily achieved by similar products on the market.
There are also other factors that affect the drawing effect. For example, the material of the workpiece to be processed, the shape, the state of the surface before drawing, and the process parameters of the drawing. Analysis of these relevant influencing factors can deepen the understanding of wire drawing processing, so as to better design the drawing process and solve the problems in the drawing process.

(1) Material of the workpiece to be machined: The hardness of the material has a significant effect on the effect of the wire drawing. The same drawing method, abrasive material, the effect of drawing is different for different materials.
(2) The shape of the workpiece: the size of the wire drawing area, whether the surface is flat, the curvature of the 3D surface, the presence or absence of protrusions, etc. are all factors to be considered.
(3) The thickness of the workpiece material is sometimes also considered in the wire drawing process. For thin-walled sheets, it is easy to cause the workpiece to warp and deform after drawing, which is caused by the difference in stress on both sides of the sheet.
(4) Brushed surface condition: Some raw materials have been polished before drawing, and some raw materials are pre-patterned on the surface.
(5) Process parameters of wire drawing: process parameters during wire drawing, such as the speed of feeding speed, the speed of grinding product, whether to set the swing, whether to use cooling lubricant, how to place the workpiece feeding, etc. Have an impact.
(6) After the wire drawing process is completed, in order to protect the line of the surface, there is also a post-treatment of the wire drawing, and the light metal material such as aluminum alloy and magnesium alloy must be anodized or chemically converted. For stainless steel, various protection treatments can be selectively performed. Such as passivation, ion plating, blackening, color and varnish.

Product Description: Strong cutting force, can partially replace the traditional cloth grinding wheel, sponge cloth wheel and rubber sand cloth wheel, can cover the thick lines left by the abrasive cloth belt, and the effect of fine burrs and continuous repair on the castings is excellent and the fine lines are fine after grinding. Beautiful. It can be used for manual and automatic grinding, intermediate or rear line processing and eliminates inconspicuous surface flaws. The nylon wheel produced by our company is refined by special process, which has the advantages of no hairiness, no blackening, and more wear and sand. It is not easy to have with similar products.
