Double disc grinding machine for different materials processing strategy and adjustment method

As an efficient machining equipment, double disc grinding machine is widely used in precision machining of various materials. However, different materials have different requirements for the grinding process due to the differences in their physical and chemical properties. Therefore, it is crucial to choose appropriate machining strategies and adjustment methods for different materials.

First, machining strategy for metal materials

Metal is one of the most common processing objects of double disc grinding machines. For metal materials, the usual strategy is to select the appropriate grinding wheel and grinding parameters.

Grinding wheel selection: for metals with high hardness, such as stainless steel, cemented carbide, etc., the grinding wheel with high hardness and good self-sharpening should be selected. For metals with lower hardness, such as aluminium alloy, copper, etc., the grinding wheel with slightly lower hardness and higher grinding efficiency can be selected.

Adjustment of grinding parameters: In the grinding process, spindle speed, feed speed and other parameters need to be adjusted according to the hardness and toughness of the metal material. Generally speaking, the metal with higher hardness needs higher rotational speed and lower feed rate to reduce the grinding force and thermal influence.

Second, the machining strategy of non-metallic materials

Non-metallic materials, such as ceramics, glass, etc., have more stringent requirements on the grinding process due to their high hardness and brittleness.

Grinding wheel selection: for non-metallic materials, usually choose a finer grain size, moderate hardness of the grinding wheel, in order to reduce the grinding process of broken and cracked.

Adjustment of grinding parameters: The grinding of non-metallic materials requires more caution, and usually adopts lower rotational speeds and feed speeds to avoid overheating and cracks. At the same time, the type and flow rate of the grinding fluid also need to be adjusted according to the material characteristics, in order to maintain good cooling and lubrication effect.

Third, the processing strategy of special materials

For some special materials, such as magnetic materials, composite materials, etc., the machining strategy of the machine needs to be more flexible and customised.

Grinding wheel selection: for magnetic materials, you need to choose the magnetic insensitive or anti-magnetic grinding wheel. For composite materials, it is necessary to select appropriate grinding wheels and grinding parameters according to the composition and characteristics of the material.

Adjustment of grinding parameters: The grinding process of special materials requires more detailed parameter adjustment to ensure processing quality and efficiency. For example, for composite materials, it is necessary to control the temperature and pressure during the grinding process to avoid material delamination or destruction.

Summary

The processing strategy and adjustment method of double disc grinding machine for different materials need to be flexibly selected according to the characteristics of the material. In the actual processing, in addition to selecting the appropriate grinding wheel and grinding parameters, it is also necessary to pay attention to the type and flow of grinding fluid, dressing and replacement of grinding wheels and other details. By continuously optimising the processing strategy and adjustment method, the processing efficiency and quality of it can be significantly improved to meet the processing needs of different materials.
