  • Product Advantages

    Sanxin Product Advantages 

    Sanxin non-woven abrasives come into being with special fiber as basic material bound with grinding ore sands. Due to different grain size, variety and method of sticking to fiber, Sanxin abrasives have different functions, which can be used for clearing, deburring and other purposes. In addition, our products are complete in shape, variety and size, which can meet your different purposes and demands.

    Advantages of Sanxin industrial abrasives :

    *Even grinding force and even processing results 

    Owing to even distribution of ore sands on the fiber, when the surface layer is worn, new grinding velvet can immediately exert its function helping achieve even, smooth and graceful surface.

    *High water resistance

    Special fiber materials are resistant to water and oil. 

    *High plasticity

    Good flexibility, suitable to all shapes of grinding charges.

    *Dirt does not block grinding velvet joint

    New velvet surface will be generated naturally after old grinding velvet is worn, hence dirt will not block the joints, keep the grinding surface always sound. 

    *Increasing surface adhesion of grinding charges

    Grinding velvet will leave super minor traces on the article’s surface, which can increase surface real area, favorable for promoting adhesion effect of spray painting and coating. 

    *Controlled cutting

    The grinding charges will not be extremely cut, hence avoiding bad products. 

    *Being rustless and no dropping

    The product is safe and convenient to use and will not get rusted and dropped like wire brushes. 

    *Safe working environment

    Noise, dust and error are taboos of safe working. Sanxin industrial abrasives feature in low grinding sound and little dust, providing users a comfortable working environment.

  • Operating suggestions

    (1) Meanings of common specifications

    Non-woven abrasive products have many varieties and specifications according to different kinds, grain size and organization density (hardness) of abrasives. 

    Abrasive: generally corundum and silicon carbide; usually corundum is used for grinding metals and silicon carbide is selected for grinding hard and brittle materials or timbers.

    Grain size: the larger the grain size, the higher grinding efficiency is; courser lines on the grinding surface result in lower finish and looser mesh fiber structure. 

    Organization density has influence on surface quality of work pieces: compared with lower density, higher density will result in clear lines, and the work piece is invulnerable to subjecting to inclined lines and breakage; with lower density, wheel sand texture is more consistent and it is also invulnerable to have the work piece surface burned.

    (2) Some parameters during use of non-woven grinding wheels

    The rotating speed of grinding wheels have influence on treatment results of work pieces and service life of sharper: when the work piece is made of hard materials and surface treatment effect is required to be excellent, high rotation speed is required, but with corresponding shorter service life; when the work piece is made of soft materials, low rotation speed is required, resulting in course surface treatment results.

    Feeding speed also has influence on partial lines of work pieces: higher feeding speed leads to shorter time of partial cutting and fewer line segments; while lower feeding speed allows for longer time to treat partial lines.

    Pressure when grinding wheel is grinding work pieces: higher pressure may lead to injury of burns and deform the grinding wheel; and lower pressure many cause unclear lines and low efficiency.

    (3) Using environment 

    Non-woven grinding sheet can be used in water, oil or other corrosive, without worrying about rusting of wire balls and sand dropping of common sand paper. It can be used in combination of a backing plate or directly by hand. Use in humid environment may lead to decrease of product durability, so it shall be well protected from moisture during storage and use.

    When there are high requirements on the surface, some lubricant can be used. Its heat radiation is effective, hence improving surface color and reducing dust. 

    When there are high requirements on the surface, some lubricant can be used. Its heat radiation is effective, hence improving surface color and reducing dust. 

    Rotation speed: it is an important fact which can influence processing effect, efficiency and service life of wheels. Actual speed shall be determined according to materials of work pieces and processing effect.

    Rotation direction: winding wheel must rotate at the direction marked on the wheel side. And rotation direction of other wheels is not limited 

    Working pressure: generally light or medium degree pressure shall be imposed. Excessive pressure shall be avoided to protect wheel from deforming or damaging work piece surface.

    Ventilation: generally ventilation may lead to unconscious lines and uneven work piece surface.

    Work piece treatment effectSuggested line speed
    Finishing line2.5-15 m/s
    Composite materials/soft sections6-13.5m/s
    Surface cleaning10-25m/s
    Final polishing pretreatment10-32.5m/s
    Removing scales25-32.5m/s

  • Precautions

    Safety precautions:

    wear proper personal protective equipment (PPE) during operation.





    suport_4_1.gif1.Excessive fast rotating speed will lead to breakage of grinding wheel hence causing injury. The rotating speed shall not exceed the maximum limit marked on the grinding wheel.
    suport_4_2.gif2.It is required to remove flammable substances on the site and sparks shall not splash toward eye and body. During dangerous operation, workers shall wear appropriate mechanical protective cover to safely operate the product under direction of factory engineer (technician). When starting work, workers shall ensure that there is no person standing in the front or at the back of the grinding wheel. Incorrect use may lead to breakage of grinding wheels and cause injury.
    suport_4_3.gif3. of grinding wheels may lead to breakage and cause injury. It is forbidden to enlarge middle hole or change its shape, and wheels with gouge mark or laminated wheels shall not be used. In case of shaking or swaying during operation, the grinding wheel shall be stopped immediately. The breakage or swaying of the grinding wheels may be caused by below reasons: too large spindle; too tight screws; there are convexes on the edge of the wheel, or wheel edge is less than 1/3 of wheel diameter, or the diameter is not consistent and is bended.

    4.Do not use or store grinding wheel under the ambient temperature >40 C°or<5 C°
