The demands placed on the workpiece surfaces depend on the respective application and can be very diverse. They range from protection against wear, corrosion resistance, thermal insulation, and electrical insulation, to an improved aesthetic appearance. In practice, however, you will rarely find the condition that components are only exposed to one type of stress. Usually there is a combination, e.g. Abrasion with simultaneous high thermal load, or the like. The most common requirements are wear and corrosion resistance, which the respective coatings must then withstand. The importance of such surface treatments and the resulting challenge for the grinding process was recognized early at Meister and the development of suitable abrasives was promoted.

HVOF (High Velocity Oxygen Fuel Spraying)

High Velocity Oxygen Fuel Spraying is one of the newer methods of thermal spraying and is characterized in comparison to conventional flame spraying by a gas jet escaping with supersonic speed. Thermally sprayed layers have a rough surface with roughness depths between 5 and 20 μm. Since a certain final dimension and surface quality are often specified for the components, this makes post-processing such as Grinding required. Here, the special tools from Meister are used, which give the treated parts the finishing touch.

Brake discs

With traffic-related particulate matter pollution - which is largely caused by the abrasion of tires and brakes - it is important to reduce the formation of particulate matter by using more wear-resistant materials. For this purpose, brake discs are coated with high-strength materials such as tungsten carbide to reduce their wear. However, since this coating is very difficult to machine in further processing, suitable tools are required. The solution: the latest generation of Meister grinding technology.
