The causes of grinding cracks may be as follows: the surface stress of the workpiece exceeds the fracture limit, that is, the workpiece has residual mechanical stress and thermal stress in the surface part due to previous grinding or heat treatment. Because this part of the grinding just to maintain the balance of the stress, resulting in its residual stress over the strength of the workpiece, from some will produce a grinding crack.

The glass is wind-proof, light-permeable, stable in performance, various types have different characteristics due to the use of different occasions, the scope of application is very wide. When we are choosing glass, besides paying attention to price, still answer its kind and performance to have certain understanding, make full use of strong points to avoid weak points, just can find the material that suits to use m

Powder metallurgy is widely used in automobile, motorcycle and other parts. the work piece precision can reach Ra 0.003mm, the dressing cycle can reach More than 10,000 pieces by using More super hard company’s end face CBN grinding wheel.

Dressing stones for grinding wheels are available in many different shapes. Choose from a single point diamond dresser with layered clusters, blade-type dressers with hand set diamonds, and grit dressers with uniform distribution of diamonds. Each dresser will give you a distinct finish. As you apply the grinding wheel dressing stick to the surface of your wheel, you’ll remove the top layer of the wheel and reveal a clean, sharp surface for future projects.

Diamond blade saws are more than capable of cutting a variety of materials, so begin by thinking about your needs. For instance, do you want a saw that will work with different things or one that works best with something specific, such as stone or granite.

Today, development and use of these specialized tools have expanded to various industries, as demand never ceases and new applications are being discovered. One of the most demanded tools is the “resin-bonded wheel”, which is manufactured through the curing process of bonding diamond or CBN abrasives, with inorganic fillers, and using resins as binders, such as phenol and polymer. Resin bonded wheels are now effectively applicable to ail sorts of grinding operations such as surface grinding, cylindrical and centerless grinding, grooving and internal grinding, etc. It is ideally used for grinding super alloys, cermet, ceramic, glass, ferrite, high-speed steel, tool alloys, and many other new ultra-hard materials.

Superabrasive grinding wheels have two equally important components. While the grit, (diamond or CBN) does the work, it couldn’t function without a partner holding it in place. In the case of resin bond grinding wheels, that partner is phenolic resin.

Diamond wheels provide the maximum performance and high-speed cutting on demanding materials. Proper care and maintenance will ensure that the wheel gives the superior results for the maximum time. The steps are not difficult and well worth the effort.
