Diamond cup grinding discs for ceramics

After cutting the tile to the required size using a diamond blade, no matter how clean the tile edge is, it is additionally processed. Professionals often need to form tile corners, which requires cutting the tile at a 45-degree angle or grinding it. For edge processing and grinding 45-degree angles, special grinding discs for ceramics are used. Some types of grinding discs are used for chamfering tile edges at a 45-degree angle, while others are used for edge processing. Let’s take a closer look at the topic of tile processing using a tile chamfering disc and find out which tool should be used for specific tasks.

Performed operations

With a ceramic tile grinding disc, a huge number of different operations can be performed, which are divided into two categories: cleaning and roughing.

Roughing operations

These are operations intended for rough processing, after which additional processing will be carried out using cleaning grinding discs for ceramics. The most common roughing operation for ceramics is cutting at a 45-degree angle. Some professionals do this using diamond blades and then process it with tile grinding discs, while others fully form the 45-degree angle using a milling cutter.

What are the characteristic features of such a tool as a tile grinding disc?

• Metal body
• Metal bond with diamonds
• The diamond layer has various indentations and protrusions
• Large diamond grit
• Optimal rotation speed above 10,000 rpm

Thanks to the large diamond grit and indentations in the diamond layer, a high grinding speed of ceramic tiles is achieved, but the main disadvantage is that chips may be visible on the edge. Therefore, professionals try not to approach the edge too closely with such tile grinding discs.

Cleaning operations

Cleaning operations in ceramic grinding are performed directly before installation and are aimed at giving the tile the most aesthetic appearance possible and smoothing all chips and irregularities. Such operations include:

• Leveling the tile face
• Creating uniform chamfers on edges
• Polishing chamfers and edges
• Removing irregularities after cutting at a 45-degree angle
• Polishing 45-degree angles
• Removing visible chips from the tile edge

Since these are finishing operations, they should not be performed with a regular metal diamond grinding disc for tiles; instead, special polishing wheels are used. Their main differences from metal diamond grinding discs for tiles:

• Soft organic bond with diamonds
• Very fine diamond grit
• Mounted on a flexible base for polishing
• Operate at reduced speeds (2000 - 5000 rpm)

Thanks to such ceramic tile grinding discs, it is possible to create perfectly neat and aesthetically beautiful corners and joints of tiles.

Features of tile grinding discs

Tile grinding disc diameters

There are several popular diameters of tile chamfering discs used by tile installation professionals:

• 125 mm
• 115 mm
• 100 mm

125 mm cutters are most often used for surface preparation before tile installation.

115 mm is a popular diameter for rough tile processing cutters.

100 mm are organic polishing wheels for finishing operations.

Grinding speed

All types of tile grinding discs are designed for processing tiles using an angle grinder, but they can operate at different speeds. A very important criterion when choosing an angle grinder for tile grinding is the ability to adjust the speed. Grinding discs for finishing operations must not operate at maximum speed of the angle grinder, as they overheat significantly and also overheat the material. As a result, the processed part of the tile will have discoloration, and the grinding will not be properly completed. On the other hand, rough grinding discs perform their tasks most efficiently at maximum angle grinder speed, and if it is reduced, chips will become significantly larger and the grinding process will be slower.
