Product Induction

The GZ4232 CNC Automatic Horizontal Band Saw Machine is an automated metal cutting solution designed for the efficient processing of small and medium-sized round bars, pipes, plates, and various ferrous metal materials.

The machine combines mechanical, electrical, hydraulic, and PLC control systems to achieve automatic workpiece clamping, automatic feeding, automatic cutting, and automatic saw-frame return. It is designed for continuous and batch cutting applications where consistent cutting length, stable operation, and reduced operator intervention are required.

The GZ4232 features a hydraulic stepless feeding system, a rear hydraulic feeding table, and grating-scale positioning. A single feeding stroke can be set from 2 to 1000 mm, while multiple feeding cycles can be used when a longer feeding length is required.

With a maximum cutting capacity of Ø320 mm for round material and 320 mm for plate material, the GZ4232 provides a practical automated solution for metal-processing factories requiring repeatable cutting operations.

The machine also supports both automatic and manual operation, allowing operators to switch to manual control when processing small batches or carrying out machine adjustment and maintenance.

Automation Features

1. Automatic Workpiece Clamping

The GZ4232 uses a hydraulic workpiece clamping system.

The cutting vise and feeding vise can operate separately, allowing the workpiece to be securely held during the cutting and feeding processes. The upper clamping mechanism works with the cutting cycle to improve workpiece stability.

This configuration helps reduce workpiece movement during cutting and contributes to stable cutting accuracy.

2. Automatic Feeding

The machine is equipped with a rear hydraulic feeding system with grating-scale positioning.

The feeding system supports a single feeding stroke of 2–1000 mm, while multiple feeding cycles can be performed when the required length exceeds 1000 mm.

This makes the GZ4232 suitable for repetitive cutting of different finished lengths without requiring manual measurement and feeding for every piece.

3. Automatic Cutting Cycle

After the operator enters the required cutting length and quantity into the control system, the machine can automatically execute the programmed cutting cycle.

The system controls:

• Workpiece clamping
• Material feeding
• Saw blade operation
• Saw-frame movement
• Feeding and return
• Cutting quantity counting

After the preset quantity has been completed, the machine automatically stops.

4. Automatic Saw-Frame Return

After cutting is completed, the saw frame automatically performs a rapid return movement.

This reduces non-cutting time between cycles and helps improve overall production efficiency.

5. PLC + Touchscreen Control

The GZ4232 uses a PLC control system with touchscreen and push-button operation.

The touchscreen provides digital parameter setting and machine-status information, while physical buttons are available for convenient manual control.

Operators can set cutting data and cutting quantities through the control interface, allowing the machine to automatically complete the programmed production cycle.

6. Automatic Counting and Batch Cutting

The control system can automatically count completed cuts and stop the machine after the preset quantity has been reached.

The system can also store one or five groups of cutting data for continuous cutting operations, making the machine suitable for batch production and multiple-size cutting requirements.

7. Hydraulic Stepless Feed Control

The saw blade feed is controlled by a hydraulic system with stepless speed adjustment.

The operator can adjust the feeding speed according to different materials and cutting conditions, helping achieve a more suitable cutting process and reducing the risk of tooth damage.

8. Dual-Column Guidance Structure

The machine uses a main and auxiliary column structure.

The main round column supports the vertical movement of the saw frame, while the auxiliary square column provides additional guidance and adjustment. This structure is designed to maintain stable saw-frame movement during cutting.

9. Automatic Band Saw Blade Chip Removal

A wire-brush chip-removal system is installed to remove residual chips from the band saw blade.

Cooling fluid is also used to clean chips from the saw teeth and help prevent chip accumulation in the tooth gullets. This helps maintain cutting performance and extend band saw blade service life.

10. Automatic Band Break Protection

The machine is equipped with an automatic stop function in the event of band saw blade breakage.

When the saw blade breaks, the machine automatically stops to help protect the equipment and improve operational safety.

11. Automatic Bundle Cutting

For smaller-diameter bar materials, the GZ4232 can perform bundle cutting.

Multiple workpieces can be arranged within the allowable cutting area and clamped together, allowing several pieces to be processed simultaneously and improving batch-production efficiency.

Technical Specifications

Customization Options

The GZ4232 can be configured according to the customer's material characteristics, cutting length, production volume, and automation requirements.

1. Feeding Length Configuration

The standard feeding system supports a 2–1000 mm single feeding stroke.

For finished lengths exceeding 1000 mm, multiple feeding cycles can be programmed to achieve the required cutting length.

2. Automatic or Manual Operation

The GZ4232 supports both automatic and manual operating modes.

Automatic mode is suitable for batch production and continuous cutting.

Manual mode can be used for:

• Small-batch cutting
• Machine adjustment
• Maintenance
• Workpiece positioning
• Individual machine movements

This gives operators greater flexibility when switching between production and setup operations.

3. Bundle Cutting Configuration

For small-diameter bars, a bundle cutting system can be configured to clamp multiple workpieces simultaneously.

This is particularly useful for high-volume production where individual-piece cutting would result in excessive loading and unloading time.

4. Material Handling

The standard configuration includes two 600 mm feeding racks.

For different factory layouts or production lines, additional material handling and feeding solutions can be evaluated according to the customer's requirements.

5. Automation Integration

For customers requiring higher levels of production automation, the machine can be evaluated for integration with upstream and downstream equipment, such as:

• Material loading systems
• Roller conveyors
• Finished-product collection systems
• Automatic material handling
• Production-line control systems

The specific integration solution should be confirmed according to the workpiece dimensions, production process, and factory layout.

Application

The GZ4232 is designed for cutting small and medium-sized round bars, pipes, plates, and various ferrous metal materials.

Steel Bar Cutting

Suitable for automated cutting of steel bars into consistent finished lengths for further machining or assembly.

Pipe and Tube Cutting

The machine can be used for repetitive cutting of metal pipes and tubes within its cutting capacity.

Plate Cutting

With a maximum plate cutting capacity of 320 mm, the GZ4232 can be used for a range of metal plate cutting applications.

Batch Production

Automatic feeding, automatic clamping, quantity counting, and automatic machine stopping make the GZ4232 suitable for repetitive batch-cutting operations.

Multiple-Length Cutting

The control system can be programmed for different cutting lengths, while multiple feeding cycles allow longer finished lengths to be achieved. This makes the machine suitable for production environments processing multiple specifications.

Automotive and Component Manufacturing

The technical document specifically identifies industries such as bearing manufacturing, standard-part manufacturing, and automotive parts manufacturing as application areas for CNC automatic band saw machines.
