Polishing and drawing machine belt pattern type analysis
Vacuum metal polishing machine belt is mainly used for flat plate parts, stainless steel plate, carbon steel plate, aluminum plate, copper plate, titanium alloy all kinds of non-ferrous metals, rubber and plastic materials, such as deburring, polishing and grinding, the use of the surface is smoother.
The core types and characteristics of the belt pattern of polishing drawing machine
The belt pattern of polishing drawing machine directly affects the surface treatment effect and equipment efficiency. Mainstream patterns can be divided into the following 5 categories:
1. straight pattern (parallel pattern): the pattern is arranged in a straight line, and the depth is usually 0.5-1.2mm. the advantage is that the friction is uniform, suitable for fine polishing of stainless steel and aluminum alloy, but it is easy to residual scratch.
2. oblique pattern (herringbone pattern): pattern is 30 ° – 45 ° oblique angle, depth of 1.0-1.5 mm, through the cross force to reduce material loss, commonly used in copper rough polishing, efficiency increased by about 20% (Source: Germany ContiTech experimental report).
3. grid pattern: diamond or square raised structure, depth 1.2-2.0mm, mostly used for high hardness metals (such as titanium alloy), can disperse the stress, extend the life of the belt to 1.5 times of the ordinary models.
4. wave pattern: continuous curved design, depth of 0.8-1.5mm, suitable for curved workpiece, can reduce the dead angle of polishing, but wear resistance is poor.
5. Composite grain: combining straight grain and oblique grain, depth 1.0-1.8mm, strong versatility, but higher cost, mostly used for automotive parts and other precision machining.
