Profile grinding wheel for roll industry

The worn profile of the carbide grooved rolls that are used in wire rolling mills has to be regularly reground. Each profile size requires its own tool. Depending on the application, diamond tools with a metal bond, resin bond or electroplated tools are used.

A profile diamond grinding wheel is a specialized type of grinding wheel used in the roll industry for precision grinding of rolls. It is designed to grind and shape the contours of various types of rolls, such as steel, paper, textile, rubber, or any other material used in industrial processes.

Here are some key features and characteristics of a profile diamond grinding wheel for the roll industry:

Diamond Abrasive: The grinding wheel is typically made with a diamond abrasive, which is one of the hardest materials known. Diamond abrasives offer superior hardness and wear resistance, making them ideal for grinding hard materials like rolls.

Profiled Shape: The grinding wheel has a profiled shape that matches the desired shape of the roll surface. It may have a complex geometry to accurately replicate the required profile, including convex, concave, or intricate patterns.

Bonding Material: The diamond abrasive is held together by a bonding material, which can be resin, metal, or a combination of both. The choice of bonding material depends on the specific application requirements, such as the type of material being ground, the grinding conditions, and the desired surface finish.

Grit Size: Profile diamond grinding wheels are available in different grit sizes, ranging from coarse to fine. Coarser grits are used for rough grinding and removing larger amounts of material, while finer grits are used for finishing and achieving a smoother surface finish.

Cooling and Lubrication: Grinding generates heat, so it is crucial to have a cooling and lubrication system in place to prevent overheating and to improve the wheel’s performance and longevity. This can involve using coolants or water during the grinding process.

Precision and Accuracy: Profile diamond grinding wheels are manufactured with high precision to ensure accurate grinding and replication of the desired profile. They are designed to deliver tight tolerances and consistent results, meeting the stringent requirements of the roll industry.

Dressing: Over time, the diamond abrasive may wear down or become clogged with grinding debris, reducing its cutting efficiency. Dressing is the process of removing worn abrasive grains and refreshing the cutting surface of the wheel. Various dressing methods, such as single-point or rotary dressers, can be employed depending on the wheel and roll specifications.

Customization: Profile diamond grinding wheels can be customized to meet specific requirements, including the size, shape, and bonding material. Manufacturers can produce wheels tailored to individual roll profiles, ensuring precise and efficient grinding operations.

It’s important to note that the specifications and design of profile diamond grinding wheels for the roll industry can vary depending on the specific application, roll material, and industry standards. Consulting with manufacturers or experts in the field can provide more detailed and up-to-date information for specific requirements.
