Tips for Choosing the Right Diamond Cup Wheel
Diamond grinding wheels are very popular in the home improvement and construction industries. They are very effective in polishing, grinding and cutting concrete, hard concrete, granite, marble, field stone, and even coating or paint removal. Whether used for simple cleaning, or for shaping and polishing stone or concrete surfaces, diamond grinding cups are one of the most popular choices for different types of diamond grinding wheels. It is a metal bond industrial diamond tool made by cold pressing or welding a diamond bit on a metal wheel.
Different types of diamond grinding cup wheels
Diamond grinding cup wheels are available in a variety of sizes, each suitable for a different type of use. Therefore, first determine the nature of the work, and then select the diamond cup wheel accordingly. For example, if the workload is heavy (such as grinding stones and concrete), diamond grinding cups with large diamond segments must be used. Smaller diamond segments are ideal for lighter jobs such as epoxy coatings, glues, paints and other such surface coatings.
Diamond grinding wheels can be classified by the following factors:
diamond grit
diamond bond
diamond hardness
Diamond Concentration
The differences in these market segments determine the availability of grinding cup wheels for different purposes. For example, if you choose a cup wheel for concrete grinding, a softer bond is suitable for harder floors and a harder bond for relatively soft floors.
Diamond cup grinders are often used for grinding with different roughnesses. Concrete grinding involves two stages.
The first stage includes coarse grinding. This stage requires a soft diamond bond and high diamond hardness. During the grinding process, diamonds are more prone to dullness. The diamond grain size also needs to be larger. At this stage, it is best to use a diamond grit between 35 and 50. The diamond concentration in the cup needs to be very low.
The second stage is fine grinding. This is also called polishing. Hard-bonded diamonds are used at this stage because they are more precise. Also, softer diamonds can be used in the process since diamonds don’t face the problem of breaking down quickly. The diamond grit chosen for this job is generally between 80 and 120. In this case, the concentration of diamond on the disk is high.
