When maximum productivity is paramount, metal bond grinding tools offer the long life and low maintenance you need.

Suitable for all levels of both wet and dry grinding from light polishing to aggressive CNC grinding, metal bond abrasive tools are built for endurance and performance.

Metal bonded tools are created from the sintering of powdered metals and other compounds with either Diamond or Cubic Boron Nitride (CBN). This process produces an extremely strong product that holds its shape well during use. Metal Bond maintains a long and useful tool life with a reduction in the frequency of dressing. Generally, Metal Bond wheels have the hardest matrix, therefore it performs best in operations under flood coolant.

One weakness to be aware of with metal bonded grinding wheels is that they are not easily dressed. Unlike resin and vitrified wheels, the bond material can't be cut away to release dull grit and expose new edges.

The metal bond diamond sintered grinding wheel is compact, and in order to pursue high holding power of the abrasive in its manufacture, its density is generally used as an important indicator to measure the quality of the grinding wheel. Due to the high densification of the metal bond diamond grinding wheel, it is difficult to shape and sharpen after use and after wear.

Mahlen Abrasive have proposed to control the metal bond formulation to match the wear rate of the diamond abrasive to ensure proper wear of the bond during the grinding process, and the new abrasive particles are continuously exposed to obtain the self-sharpening ability of the grinding wheel.

Metal Bond Diamond Tools provide:

• Long life Metal bond grinding wheels last longer than those made by other methods. This boosts productivity by cutting down on dressing frequency and wheel changes.
• Intricate Designs Complex forms can be created, and since wear rates are low they last longer than in other types.
• Impervious to Alkaline Coolants Unlike resin grinding wheels which are susceptible to chemical attack—especially at elevated temperatures, metal bond's impervious properties make it well-suited for use with grinding fluids.
• Heat quickly dissipates through the metal core This property makes metal bond appropriate for high material removal rate operations like creep feed grinding, which are also helped by the ability to use coolant.
• Superior form holding, impact resistance With excellent hardness and wheel retention properties, metal bond performs outstanding interrupted cuts while retaining the tool's original dimensions during everything from light polishing to the most aggressive CNC grinding actions including centerless, cylindrical, creep feed, deburring and cutoff applications.
• Compatible with many materials Because metal bond grinding wheels are sintered with cobalt, copper, mill, silver or stanum power, they work exceptionally well on glass, refractories, ceramics, silicon, semiconductors, quartz, and a variety of other surfaces
