  • Introduction of kerb stone

Kerbstone are a type of strip stone, which refers to a strip-shaped object cut from stone and used as a boundary stone on the edge of the road. kerbstones are also called curbstones or kerbstone. kerbstones are the boundaries that distinguish the roadway, sidewalk, green space, isolation belt and other parts of the road on the road surface, and play a role in ensuring the safety of pedestrians and vehicles and ensuring the neatness of the road edge.

  • Classification of Kerbstone

According to the cross-sectional size of the Kerbstone, it can be divided into H-type Kerbstone, T-type Kerbstone, R-type Kerbstone, F-type Kerbstone, TF-type vertical Kerbstone and P-type flat Kerbstone. According to the line type of the Kerbstone, it can be divided into curved Kerbstone and straight curbstone.


  • Material requirements for Kerbstone

Material requirements for Kerbstone: Kerbstone are made of natural granite with uniform texture and machined. The strength of the stone must be qualified. The color must be uniform, the surface must be free of cracks, the edges and corners must be complete, the appearance must be consistent, there must be no obvious spots or color differences, and weathering is not allowed. During loading and unloading, it is not allowed to be dropped, smashed, bumped, or bumped to avoid damage.

  • Processing requirements for Kerbstone

Processing requirements for Kerbstone: Cut to uniform length, the exposed surface must be machine cut and polished, the allowable length error is within ±20mm, and the allowable width, thickness, and height errors are within ±2mm.

  • Chamfering of Kerbstone

Kerbstone is the most common type of facing stone. When processed, the Kerbstone is a square prism. Many of the Kerbstone we see have a bevel or rounded corner. This bevel and rounded corner are what we will talk about below. Chamfering refers to cutting the edges into a certain slope. So how do you chamfer Kerbstone?

  • How to chamfer the kerb stone ?

There are many ways to chamfer kerb stones. The more advanced ones include fully automatic chamfering, semi-automatic chamfering, and manual chamfering.

  • automatic chamfering

Fully automatic chamfering is done by using a special chamfering machine. After setting the parameters, it can work automatically. This machine forms an assembly line with the kerbstone cutting machine, and the cutting and chamfering are integrated into one, omitting the cumbersome process and being fully automated. Only 1-2 workers are needed to cooperate, saving employee costs and high cutting and chamfering efficiency. This machine is suitable for factories processing kerb stones.

The kerb stone chamfering machine independently developed and manufactured by Dafon company can be customized according to customer needs, realize intelligent flipping and intelligent transmission, with a high degree of automation, and a series of functions such as chamfering, rounding and polishing. The enlarged frame is made of high-quality steel materials to ensure the high standard of kerbstone chamfering, improve overall work efficiency and reduce overall costs.


  • semi-automatic chamfering

Semi-automatic refers to the use of infrared stone cutting machines for chamfering. When processing kerb stones, first cut the rough stone into the required thickness, then use a cutting machine to cut it into the required specifications, and finally adjust the inclination of the saw blade to chamfer. Of course, this method is only suitable for chamfering but not rounding. Semi-automatic chamfering machines are suitable for factories that process various flamed boards, smooth boards, litchi surfaces, and various kerb stones. Compared with fully automatic, this type of chamfering has lower efficiency and lower product standards.

  • Manual chamfering

The most commonly used application of artificial chamfering is rounding. Generally, 1/4 rounded corners of 1-2cm are the easiest to make, which can be completed by rubbing with a grinder. The most difficult is the large rounded corners of about 5cm. This kind of rounded corners needs to be ground out little by little by workers, and a uniform curvature must be maintained during grinding, otherwise the kerb stones cannot be arranged neatly.
