Tool Grinding Fluids

Tool manufacturing is an important part of metalworking Industry. Machine tools and grinding wheel technologies have progressed continuously in the tool grinding process with an objective to improve on grinding parameters like grinding speeds, higher feed rates, better surface finish etc.

Advanced Grinding Fluids : The Right Balance of Lubrication, Cooling and Flushing

The grinding oil must follow this evolution by providing the right balance between cutting and lubrication. A frequent problem with “regular grinding oils” is its focus on over lubricating the work area. These regular grinding oils with high viscosity reduces the grinding wheel’s cleaning ability and as a result the grinding wheel does not cut enough.

Tool grinding process generates a lot of heat. The gradual rise in temperature between the workpiece and the wheel leads to microcracks in the tool, grinding burns and reduce the grinding efficacy of wheel. The tool grinding fluid should provide optimal lubrication to reduce frictional heat, clean the chip out of machining area, enable higher grinding speeds and metal removal, provide cooling to avoid thermal damage to the grinding tool and workpiece.

Cobalt Leaching While Carbide Grinding

Another critical aspect that comes into play while grinding carbide material is release of cobalt into cutting fluid (here grinding fluid) known as cobalt leaching. The cobalt leaching process is initiated by chemical or electrochemical reaction between the carbide surfaces and environment. Loss of cobalt leads to weakening of carbide structure and further accelerating the leaching process. Cobalt is toxic, to inhibit leaching it is important that cutting fluid provides quick heat dissipation and contains the additives that are required to deter the cobalt leaching process.

Recommended by leading tool and machine manufacturers, Bechem’s range of grinding fluids are specially formulated for grinding of carbide, high speed steel and other difficult to grind materials. The tool grinding fluids provide optimal lubricity and cooling with good flushing property to ensure hassle free grinding.
