Hengde offers various types of cutting machines, consisting of a frame, saw wheel, motor, cutting base, track, and computer control system. These machines meet different size cutting needs, offering high cutting precision and full CNC control. Based on mold shape, cutting machines are divided into two main categories: square molds and rectangular molds.

CLC & Foam Concrete Block Cutting Machine

Hengde CLC block cutting machines are designed for high-precision cutting of foam concrete, lightweight concrete and non-autoclaved aerated concrete cakes produced in square mold boxes. The cutting system combines a rigid machine frame, saw wheel, drive system, cutting platform, guide track and CNC control to convert molded concrete cakes into consistent block sizes for commercial production.
For manufacturers producing multiple block specifications, Hengde offers single-head rotary, double-head and multi-head vertical cutting configurations. Depending on the selected machine, production process, cutting tooling and material condition, high-precision CNC configurations can achieve cutting accuracy of up to ±1 mm.

The machines are suitable for new lightweight block factories as well as existing plants upgrading an older cutting system to improve dimensional consistency, production capacity and automation.

What Can This CLC Block Cutting Machine Cut?

The square mold cutting system is primarily designed for cutting molded lightweight concrete cakes after forming and initial setting.

Typical materials and finished products include:

• CLC foam concrete blocks

• Foam concrete blocks

• NAAC lightweight aerated concrete blocks

• Lightweight concrete blocks

• EPS self-insulating concrete blocks

• Other compatible cement-based lightweight block materials

The appropriate saw configuration should be selected according to the cake dimensions, material density, initial-setting condition, required block dimensions, production capacity and cutting direction.

For complete production from batching and mixing through molding, cutting and palletizing, see Hengde's Lightweight Block Production Line.

Square Mold Cake Size & Cutting Range

Cake size is one of the most important parameters when selecting a concrete block cutting machine.

For reference, Hengde's 100m³/day lightweight block production configuration uses a square mold with a cake size of:

*Actual cutting accuracy depends on machine configuration, saw system, cake condition, material formulation and operating parameters. Confirm the required tolerance with Hengde before final machine selection.

If your cake dimensions differ from the reference size, send us your mold drawing and required finished block sizes so that the cutting layout and machine configuration can be checked before quotation.

Available CLC & Foam Concrete Cutting Machine Models

Hengde provides several square mold box cutting configurations for different production capacities and cutting requirements.

HDSHM1-01 0.6-Meter Single-Head Rotary Vertical Saw

The HDSHM1-01 is designed for rotating vertical cutting of square mold box cakes. It is suitable for lightweight concrete manufacturers requiring flexible vertical cutting in a compact production configuration.

This configuration is suitable for integration with molding, demolding, peeling and downstream block handling equipment.

HDSHM01-001 High-Precision Single-Head Rotary Vertical Saw

The HDSHM01-001 is a high-precision rotary foam concrete block cutting machine designed for manufacturers requiring flexible block specifications and stable production capacity.

Its CNC-controlled cutting process allows manufacturers to produce multiple block widths and thicknesses without relying on a single fixed finished dimension.

This model is particularly suitable for manufacturers producing several block thicknesses for different wall construction applications.

It can also be integrated into Hengde's 100m³/Day NAAC Block Production Line.

HDSQ-002 Double Vertical Cutting Saw

For factories requiring greater parallel cutting capability, Hengde provides the HDSQ-002 double vertical cutting configuration.

The double cutting configuration can be considered when production capacity and cutting cycle requirements exceed those of a basic single-head machine.

Final machine selection should be based on actual cake dimensions, cutting sequence and production target.

HDSQ-003 Three Vertical Cutting Saw

The HDSQ-003 uses a multi-head vertical cutting configuration for higher-output lightweight concrete block manufacturing.

Multi-head configurations can reduce the number of cutting passes required for suitable product specifications and are intended for manufacturers seeking increased cutting efficiency.

Cutting Accuracy: Why ±1 mm Matters

Dimensional consistency is especially important for lightweight blocks used in modern wall systems.

Large variations in block dimensions can increase mortar or adhesive consumption, complicate wall installation and reduce the consistency of finished masonry.

Hengde's high-precision cutting solutions use CNC and servo-controlled configurations to improve repeatability of the cutting path. Depending on the selected system and production conditions, high-precision configurations can achieve cutting tolerances of up to ±1 mm.

However, cutting accuracy is not determined by the machine alone. It is also influenced by:

• Cake density

• Initial-setting strength

• Moisture condition

• Saw blade condition

• Cutting speed

• Guide and servo calibration

• Machine installation

• Cutting sequence

For this reason, buyers should provide their target block tolerance and raw material information during machine selection rather than selecting equipment only by motor power.

Cutting Kerf & Material Loss

Cutting kerf is the width of material removed by the saw during each cutting pass.

A smaller and more consistent kerf can help improve usable material yield, but the correct kerf depends on the selected saw system, blade specification, block formulation and cake condition.

Hengde therefore does not recommend selecting a cutting machine based on a generic kerf value alone.

For a project quotation, provide:

Required block dimensions + cake dimensions + material formulation + target capacity.

The appropriate saw blade/tooling and cutting configuration can then be matched to the production requirement, and the applicable cutting kerf can be confirmed in the technical proposal.

CNC Cutting for Multiple Block Sizes

For distributors and block manufacturers serving several construction markets, producing only one block size may limit production flexibility.

The HDSHM01-001 configuration can process cutting dimensions within 600 mm, with common widths and thicknesses including:

100 mm · 120 mm · 150 mm · 200 mm · 240 mm · 300 mm · 350 mm

This allows manufacturers to plan different lightweight block specifications according to local wall thickness and project requirements.

When requesting equipment, send Hengde your planned product matrix, for example:

We can then evaluate the cutting sequence and suitable machine configuration.

Square Mold Cutter vs. Long Mold Cutter

Choosing the correct cutting machine starts with the mold format used in your production process.

If your production process uses a rectangular or long mold box, view the Long Mold Box Cutting Machine instead.

If you are planning a new factory and have not yet selected the mold process, Hengde can evaluate the cutting system together with the overall Lightweight Block Production Line.

Where the Cutting Machine Fits in a CLC Block Production Line

A block cutting machine normally operates as one stage of the complete lightweight concrete manufacturing process.

A typical process can include:

Raw Material Feeding → Metering → Mixing & Foaming → Pouring → Mold Forming → Initial Setting → Demolding → Surface Preparation → CNC Cutting → Block Handling → Palletizing

The cutting machine therefore needs to match both the upstream cake dimensions and the downstream material handling system.

For a new project, we recommend evaluating the cutting machine together with:

• Feeding System

• Mixing equipment

• Mold system

• Demolding equipment

• Peeling Machine

• Transfer equipment

• Palletizing equipment

See the Lightweight Block Production Line for complete plant configurations.

For Existing CLC & Foam Concrete Plant Upgrades

You do not need to purchase an entirely new production line to improve your cutting process.

The square mold box cutting machine can also be evaluated as a replacement or upgrade for an existing lightweight block factory.

Typical upgrade requirements include:

Improve dimensional accuracy
Replace older cutting equipment when inconsistent finished block dimensions are affecting product quality.

Increase cutting capacity
Use a different single-head or multi-head configuration when the cutting section has become a production bottleneck.

Produce more block sizes
Upgrade the cutting configuration when the factory needs additional thicknesses or new finished product specifications.

Reduce manual adjustment
CNC-controlled equipment can simplify size adjustment and improve cutting repeatability compared with heavily manual processes.

Upgrade an existing square-mold line
Provide the current mold dimensions, cake size, machine layout and cutting process. Hengde can evaluate whether a new cutter can be integrated into the existing plant.

Cutting Test Video & Sample Verification

For industrial cutting equipment, buyers should evaluate more than the machine appearance.

A useful cutting demonstration should show:

Cake entering the cutting area → machine positioning → complete cutting cycle → finished block separation → finished dimensions and surface condition.

When evaluating a cutting machine, ask for a test or reference video using a material and cake size as close as possible to your own production conditions.

For high-precision projects, we also recommend checking finished block dimensions at several points rather than measuring only one sample.

Page recommendation: place an actual Hengde square-mold cutting video directly in this section. Do not use a generic corporate video. A real factory cutting video can significantly strengthen both buyer trust and the topical relevance of this page.

CLC Block Cutting Machine Maintenance

Regular maintenance helps maintain cutting consistency and reduce unexpected downtime.

Daily Checks

Clean cutting debris from the work area, track and cutting components after production.

Inspect visible saw components and cutting tooling for wear or damage.

Check that moving sections, guards and sensors are operating normally before starting production.

Regular Mechanical Inspection

Check:

• Saw wheel condition

• Cutting blade/tooling wear

• Guide track alignment

• Bearings

• Fasteners

• Drive components

• Lubrication points

• Cable and sensor connections

CNC & Servo System Checks

For high-precision configurations, periodically verify the cutting reference position, servo positioning and control parameters.

If finished block dimensions begin to drift, inspect both the mechanical cutting system and the control calibration instead of simply changing cutting parameters.

Cutting Tool Replacement

Do not continue using excessively worn cutting tooling solely to reduce consumable costs. Worn components can affect cutting quality, kerf consistency and finished block dimensions.

The maintenance interval should be determined according to operating hours, cutting material, production environment and actual component condition.
