Automatic Kerbstone Cutting Machine | Kerb Stone Cutter

This is a fully integrated kerbstone production line, not a single cutting machine.

The line combines:

• A multi-blade slicing machine (LYFP-1200) for width cutting

• A precision edge cutting machine (LYQB-1200) for length control

• Hydraulic roller transport connecting both machines

• PLC touch control with real-time cutting feedback

Instead of cutting, moving, measuring, and finishing kerbstones as separate steps, the entire workflow runs continuously. This structure is what allows stable batch production with fewer operators and less manual repositioning compared to standalone machines.

The line is designed for straight, standardized kerbstones used in municipal and infrastructure projects. 

Typical products include: 

• Roadside curb stones 

• Sidewalk and pavement kerbs 

• Parking and traffic island curbs 

• Rectangular kerbstones with consistent width, height, and length 

It focuses on uniform, repeatable profiles, not decorative or curved stone products. This makes it suitable for supplying public works, contractors, and large infrastructure projects that require dimensional consistency across large batches. 

The line can process granite, marble, sandstone, basalt, limestone, and quartzite, as well as concrete, cement products, and cast stone bricks.

From a structural point of view:

• The slicing machine uses 12 × 1200mm blades driven by a 22 kW motor

• The edge cutting machine uses a 1200mm blade with 55–75 kW power

This configuration allows stable cutting across both softer stones (sandstone, limestone) and harder materials (granite, quartzite), as well as concrete-based products commonly used for roadside construction.

The multi-blade system improves productivity by cutting multiple kerbstone strips from one block in a single pass.

With 12 blades mounted on the LYFP-1200, one stone block is sliced into multiple kerbstone blanks at once. This reduces:

• The number of cutting cycles per block

• Idle time between cuts

• Manual handling between operations

Compared with single-blade setups that process one piece at a time, this approach creates a continuous rhythm that supports the line’s typical output of 30–35 m³ in 24 hours under stable operation.

Width and length consistency are controlled by two dedicated stages, each designed for one dimension.

• Width control is handled during slicing, using fixed blade spacing and laser positioning on the multi-blade slicing machine

• Length control is handled during edge cutting, using automated measurement on the LYQB-1200 edge cutting machine

Because blocks move between these stages via hydraulic roller transport, kerbstones are not manually re-positioned between width and length cutting. This reduces cumulative error and keeps batch dimensions stable across long production runs.

The maximum cutting size supported by both machines is 2500 × 1800 × 450 mm, which defines the upper boundary for block and kerbstone dimensions.

This line operates with a high level of process automation, but not blind automation.

From slicing to edge cutting, material transfer is handled by a hydraulic roller conveyor system that automatically connects both machines. Once the block is positioned for slicing, kerbstone blanks move through the line without repeated manual lifting or re-alignment.

The operator mainly:

• Loads raw blocks

• Sets cutting parameters on the PLC

• Monitors operation

There is no need for manual length measurement or repeated repositioning between machines, which is where most inconsistencies occur in semi-automatic setups.

In normal operation, the line can be run by one operator per shift.

Because slicing, transfer, and edge cutting are integrated, the operator does not need to manually handle each kerbstone between steps. This significantly reduces labor compared to traditional workflows where multiple workers are needed to move, measure, and re-cut pieces.

For larger factories or higher throughput targets, additional personnel may be assigned for upstream block handling or downstream stacking, but the cutting line itself is designed for minimal direct labor input.

Installation is fast due to the foundation-free, all-in-one design.

In most cases:

• Equipment positioning

• Electrical connection

• Water and lubrication setup

• Basic operator training

can be completed within one working day.

Unlike traditional curb stone lines that require concrete foundations and several days of curing time, this line can be installed, adjusted, and put into production quickly. If the factory layout changes later, the equipment can also be repositioned more easily.

Maintenance requirements are relatively straightforward and focused on routine checks rather than complex servicing.

Typical tasks include:

• Daily blade inspection and cleaning

• Lubrication and cooling system checks

• Periodic hydraulic system inspection

The heavy-duty spindle design and cast-iron structure are intended for continuous operation, reducing unexpected downtime. Operating costs are mainly influenced by blade consumption and electricity, but the single-operator design and continuous workflow help keep overall costs lower than multi-machine, labor-intensive setups.

This production line is best suited for factories that:

• Produce large volumes of straight kerbstones

• Supply municipal, infrastructure, or public works projects

• Require stable dimensions across long production runs

• Want to reduce labor dependence and manual handling

It is not intended for decorative stone, curved profiles, or small custom batches. Its strength lies in standardization, throughput, and repeatability, which makes it most valuable for medium to large-scale curb stone producers.
