Automatic Kerbstone Cutting Machine | Kerb Stone Cutter

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.

The arithmetic is straightforward: a single-blade machine repeats one pass per kerbstone strip, so a block yielding ten strips needs ten passes plus handling between each. The LYFP-1200's twelve blades cut all strips in one pass — one setup, one cycle, one handling operation. The gain compounds across a shift: fewer passes mean less blade exposure time per block, more consistent strip thickness because all blades share the same cutting conditions, and operator time freed from repeated measuring and repositioning. For volume kerbstone orders, the multi-blade line is the difference between quoting competitively and losing the tender on production cost.

This line produces straight, dimensioned kerbstones — slicing plus edge finishing for standard roadside profiles. Curved kerbstones, radius pieces and shaped roadside elements need a different cutting geometry: the CNC kerbstone wire saw traces programmed curves through the stone without molds, which is the right machine for that product family. Many kerbstone factories run both — the line for volume straight products, the wire saw for curved and custom shapes — sharing block preparation from the same block cutter.

Three factors decide it. Existing equipment first: if you already run a capable edge-cutting station, the LYFP-1200 slicing machine alone upgrades your strip output, and the line logic comes later. Handling second: the complete line pays when material flows directly from slicing to edge finishing — if your current shop moves blocks by crane between unrelated machines anyway, the second station completes the flow your layout is missing. Volume third: below a daily kerbstone count where edge finishing is not the bottleneck, the slicing machine alone may serve; above it, the dedicated edge cutter stops edge work from throttling the whole line. Share your current equipment list and daily target with DINOSAW, and the line-versus-station answer comes from the balance calculation, not preference.

Four data sets configure the line: your raw block dimensions (length, width, height range as they arrive from the quarry or supplier) — they set table capacity and blade height needs; the finished kerbstone cross-sections (width, height, length per product type) — they set blade spacing and the edge-cutting program; your stone classes (granite, basalt, limestone or mixes) — they set blade specification and power sizing; and the daily volume per product — it sets whether the line balance needs both stations at full configuration. Send these with the inquiry, and the quotation comes back with a configured line instead of a generic specification — the same data also lets DINOSAW flag which kerbstone sizes your block yield supports best.
