No joint belt, joint belt and open sand belt

The jointless sand belt is made of special cylindrical cloth as the base material, which is stretched, polished and impregnated by the original cloth on a special equipment, and then made by gluing, sand planting, drying, etc.Jointless sand belts are also early products of sand belts, which are no longer produced.

Joint sand belt is formed by cutting, grinding, joint bonding and strip splitting of the sand belt in different sizes.Unlimited joint circumference of abrasive belt, very convenient, especially the way of joint, joint and the joint process equipment has made the development of abrasive belt joint, both in thickness, strength, soft music and even in such aspects as the joint part of the overall consistency has reached a quite high level, is the main form of abrasive belt.

Open sand strip is another kind of sand strip, which is a small sand strip formed by dividing the sand strip blank directly according to the size requirement.Open sand belts are easy to make.It is also very convenient to use, and is often used in precision machining with fine particle size, such as automotive engine camshaft, crankshaft, precision cylindrical parts grinding and polishing.The characteristics of the use of the workpiece movement speed is high, slow belt speed, long service cycle, and in the grinding area there are always new abrasive to participate in grinding, grinding surface quality consistency is very good.
