The importance of dressing and truing abrasive grinding wheels can never be over-emphasized. Dressing will restore the exposure and cutting ability of the abrasives on the wheel surface. Dressing must be performed after truing or whenever the wheel surface becomes loaded or glazed, or has lost its cutting ability. Dressing removes the unwanted residue, such as braze and steel particles, from the wheel surface. Dressing also removes a certain small portion cutting action. Truing is he procedure for eliminating any unwanted 'run-out' once the wheel has been mounted. Truing is best done wet. 

 Today's modern industrial society continues to push the development and uses of new, advanced materials and high precision machining to new heights. Along with the improvements in production processes and difficulties that arise from machining new and advanced materials, there is an increasing demand for new forms of cutting tools that go beyond the performance of conventional tools made of high speed steel, tungsten carbides, cermets, and ceramics. Polycrystalline Diamond (PCD) and Polycrystalline Cubic Boron Nitride (PCBN) are a synthetic super abrasive product, that are produced by sintering together selected diamond or CBN particles with a metal matrix using very sophisticated high temperature and high pressure technology. PCD, PCBN are by their nature, high in hardness, and more abrasive and shock resistant in all directions as compared to natural diamond. These wear resistant materials are combine of into a cutting tool. That provides outstanding life and excellent quality of cut.

Electroplated diamond or cubic boron nitride (CBN) tools are made of a single layer or multi-layers (depending on application) of either diamond or CBN particle that are attached to the tool surface using a nickel matrix. This process allows for the easy manufacture of tools with different and comp1ex forms and contours. Electroplate super abrasive tools have high exposure and concentration of diamond/CBN particles, which make faster cutting than diamond/CBN tools made by other processes. This provides high efficiency grinding on steels, FRP, ceramics, and composite materials.

Over the past twenty years, the electrical, electronic, and semi-conductor industries of the world experienced significant growth and will continue to reach greater heights at even greater speeds. These industries require ultra high precision and fine mirror-like finishes to manufacture their products. EHWA has focused it's resources and technology on these applications and provides a full range of quality, high value products to meet customer needs.
