For diamond drill bit, w elding  is t he most used method of attaching diamond segment on the core barrel . This article   is  mainly about the production process and features of welded diamond core bit . Manufacturing  process of diamond drill bit  can be divided into the following parts. 1. Diamond, iron, nickel, cobalt and other   metal  powder are selected according to the production   requirements *. Then binding   agents  are mixed with  selected powders, which is often carried out using pendulum motion mixers. ( * Diamond-related parameters are taken into consideration to meet the individual requirements of a given application, including diamond type, grit size and concentration. With 20-year experience of diamond tools manufacture, BSP TOOLS has  strict requirements on metal matrix and diamond particles selection. Our various formulas  for different application are  well received, which have been keeping upgra...

  Sandpaper  is not made of sand, but is made of fine particles of natural or synthetic origin. The particles are sieved through a screen and sorted by size, and then bonded with adhesive to a paper, sponge or cloth backing to make an abrasive that can be used on its own. Whether you choose an "electric sander" or manual sanding, the correct choice of sandpaper type and grit  is an indispensable part of perfecting the work. Sandpaper grit is classified according to the roughness of the paper, and the size of the sandpaper abrasive grinding particles is determined. There are two criteria for the measurement of grit, one is CAMI (Coating Abrasive Manufacturing Institute) and the other is FEPA (European Federation of Abrasive Producers). In general, the particle  size of sandpaper is often expressed by # and "P" plus a number. Lower numbers indicate larger grains and coarser sandpaper particle sizes, with strong grinding forces and suitable for initial sanding; while l...

  C oated abrasive s ,  also known as flexible abrasive s ,   are  product s  that consist of a thin layer of abrasive grain attached to a substrate .  Paper,   cloth,   fiber ,   film,   non-woven,   foam are used as  substrate  for coated abrasives.   The substrate  also called as backing and  can have varying   degrees of flexibility ranging from extremely flexible   (E weight cotton backings) to extremely sturdy   (Z   weight polyester backings). The backing gives the abrasive very specific grip and adhesion, stretch, tear resistance, tensile strength, flexibility and stability properties.   These  backing  are   used as backings for different types of abrasives:   rolls, belts, discs and sheet goods.   Today ,  I'm going to introduce you to paper-based coated abrasives . Paper-backed abrasives (i.e. traditional  sandpaper ) are the most afforda...
