  • Backgrounds

Despite the rapid development of stone processing equipment in recent years, specialized machining centers for countertop processing have also emerged. However, these high-cost machines are not suitable for stone processing companies that do not specialize in countertop processing. Particularly considering the thin profit margins on countertops, the payback period for using expensive machining centers is hard to predict. Currently, countertop slab processing and polishing still mainly rely on manual shaping and polishing. This traditional method not only results in low production efficiency but also leads to high labor intensity.


So, how can the stone countertops be efficiently processed, ground, and polished? This article will explore the processing, grinding, and polishing techniques of stone countertops.

  • Traditional countertop processing process:

Cutting of basin hole on countertop → Drawing of basin hole edge → Forming of basin hole edge → Grinding and polishing of basin hole


1. Cutting the edge of the basin hole

The basin hole of the countertop is usually cut with a manual cutting machine, which is convenient.

2. Make a template for the basin hole. 

3. Steps for drawing lines on the edge of the basin hole:

(1) Align the template with the edge of the basin hole

(2) Clamp the template with a clamp

(3) Draw lines along the outer edge of the template. The lines must be neat and the trajectory must be smooth.

4. Forming the edge of the basin hole Install a forming wheel on the hand grinder to further process the basin hole.

5. Grinding and polishing the edge of the basin hole There are two ways to grind and polish the edge of the basin hole: hand-held grinding and polishing, see Figure 4; manual grinding and polishing. The method shown in Figure 4 can be used for hand-held grinding and polishing. Skilled employees can grind and polish the edge of the basin hole with only 3 to 4 grinding wheels.

  • Shortcomings of traditional processing ways

The traditional processing and polishing process of countertop and basin holes mainly relies on manual forming grinding and polishing. Although it is low-cost, highly flexible, and suitable for processing small batches of countertops, it has the following disadvantages:

Low processing efficiency: Manual operation is time-consuming and labor-intensive, and it is difficult to meet the needs of mass production.

Low standard of finished products: Manual operation is difficult to ensure processing accuracy and consistency, and the quality of finished products is difficult to meet the standards.

High labor intensity: Manual operation puts a heavy burden on the workers' bodies and the working environment is poor.

Low customer satisfaction: Low processing efficiency and finished product standards lead to low customer satisfaction
