Diamond cup grinding discs for porcelain

When laying tiles, professionals face the need to cut them at a 90 or 45-degree angle, after which the edge of the tile requires additional processing. Chamfer removal and tile grinding are carried out using special cup grinding wheels. Typically, grinding wheels for porcelain tiles are made of special organic components and diamonds or metal inserts with diamonds, but there are also metal grinding wheels for porcelain stoneware. In this article, we will подробно discuss what grinding wheels for porcelain stoneware are, how to use them, and how to choose them.

Types of grinding wheels for porcelain stoneware

The most popular grinding wheels for porcelain stoneware are discs with a diameter of 125 mm, which are designed for use with angle grinders, and for polishing — 100 mm. When grinding tiles, there are two main operations:

• Rough grinding
• Polishing

Depending on the operation being performed, it is necessary to select the appropriate grinding wheels for porcelain stoneware.

Grinding wheel for porcelain tiles for rough grinding

For rough grinding of porcelain stoneware, metal cutters are used, in which synthetic diamonds act as the cutting element. Such diamond grinding discs for porcelain stoneware are designed for use with angle grinders. The optimal operating speed for most of them is 11,000–12,000 rpm (maximum speed of most angle grinders). However, some cutters may require lower speeds, so for such purposes it is better to use a grinder with speed control.

These cutters may have larger diamonds (for faster and more efficient grinding) or smaller diamonds (for finishing work). But regardless of the diamond size in the metal grinding wheel for porcelain stoneware, the tile surface requires further processing with special polishing discs for porcelain stoneware.

Polishing disc for porcelain stoneware

Polishing porcelain stoneware is the final finishing operation, which is performed using special polishing discs for porcelain stoneware. They are made of a soft organic bond, which is equipped with synthetic diamonds or metal inserts with synthetic diamonds. This manufacturing technology makes the tool very soft and sensitive so as not to damage the tile during operation.

When choosing a grinder, you should pay attention to the ability to adjust the speed, since polishing discs for porcelain stoneware operate at reduced speeds, and working at maximum speed (10,000–12,000 rpm) will damage the disc. The optimal speed for polishing porcelain stoneware is 2500–4500 rpm (first or second gear of the grinder).

There are several types of diamond grit for rougher and finishing polishing of porcelain stoneware. Typically, tile installers use several grits of polishing discs for porcelain stoneware in sequence to achieve a good result.

Polishing discs are not mounted directly on the grinder like grinding wheels, but on a special backing pad, which is screwed onto the grinder spindle. The polishing disc itself is attached to the pad using Velcro. This connection perfectly holds the disc during operation at a speed of 2500–4500 rpm. At higher speeds, the hold may be worse, however, as most tests show — the disc remains on the pad even at a speed of 12,000 rpm, although such speed is highly not recommended for polishing porcelain stoneware.

Advantages of using grinding wheels for porcelain tiles

It is impossible to calculate the purchase of tiles so that everything fits exactly to the tile size, therefore cladding premises cannot be done without cutting tiles. Also, nowadays it has become very popular to make various shelves, niches, shower trays, countertops and other products from porcelain stoneware. And when performing such tasks, the tile is cut at a 45-degree angle, then ground and polished. Diamond cutting discs for porcelain stoneware are used for cutting, which allow you to obtain clean and precise edges. This process cannot be done without grinding wheels for porcelain stoneware and polishing discs for porcelain stoneware. In general, with the help of this diamond tool, the following operations are performed:

• Tile edge processing
• Chamfer removal
• Rough grinding
• Edge polishing
• Polishing 45-degree cuts

A very important aspect is the high durability of diamond tools. With the help of a grinding wheel for porcelain stoneware, you can remove kilograms of material, and with polishing discs for porcelain stoneware you can bring hundreds of meters of porcelain stoneware edges to a perfect condition.
