Product Induction

The H-330 CNC Automatic Horizontal Band Saw Machine is an automated metal cutting solution designed for cutting round bars, plates, pipes, and other ferrous metal materials.

The machine combines mechanical, hydraulic, electrical, PLC, touchscreen, and grating-scale systems to control the saw blade rotation, saw-frame lifting, workpiece clamping, feeding, and return movements. These systems work together to complete an automatic cutting cycle with reduced operator intervention.

The H-330 features a rear hydraulic feeding system with grating-scale positioning, providing a single feeding stroke of up to 400 mm. Multiple feeding cycles can be performed when a longer finished length is required.

The machine has a maximum cutting capacity of Ø330 mm for round material and 330 mm for plate material. It uses a four-speed band saw system of 30/45/60/80 m/min and hydraulic stepless feed-speed adjustment, allowing cutting parameters to be adapted to different materials and workpiece sizes.

The H-330 also supports both automatic and manual operation, making it suitable for continuous batch production as well as small-batch cutting, machine adjustment, and maintenance.

Automation Features

1. Automatic Workpiece Clamping

The H-330 adopts a full-stroke hydraulic clamping system.

The cutting vise and feeding vise can operate separately, while the upper pressing mechanisms work together with the cutting process. During operation, at least one vise remains clamped to help prevent workpiece movement and maintain stable cutting.

2. Automatic Hydraulic Feeding

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

The standard single feeding stroke can be set up to 400 mm. When the required finished length exceeds 400 mm, the machine can perform multiple feeding cycles to reach the required length.

This configuration reduces manual measuring and repositioning during repetitive production.

3. PLC + Touchscreen Control

The H-330 uses a control system consisting of PLC, touchscreen HMI, grating scale, and proximity switches.

The system controls the main machine movements and organizes them into a programmed cutting cycle. Operators can enter the required cutting length and quantity through the touchscreen before starting automatic production.

4. Automatic Cutting Cycle

After the cutting length and quantity are entered and the machine returns to its reference position, the operator can start the automatic cutting cycle.

The machine then performs the programmed sequence automatically. Once the preset quantity has been completed, the machine automatically stops.

5. Automatic Counting

The PLC control system automatically counts the completed cutting quantity.

This is useful for batch production because operators do not need to manually count every finished piece. The machine continues cutting until the preset quantity is reached.

6. Multiple Cutting Data Groups

The control system can set one or five groups of cutting data for continuous cutting.

This feature is useful when a production order contains different cutting lengths or multiple specifications that need to be processed continuously.

7. Hydraulic Stepless Feed-Speed Adjustment

The H-330 uses a hydraulic feed system with stepless speed adjustment.

The feed speed can be adjusted according to different material types and cutting conditions, helping the operator achieve an appropriate cutting load and stable sawing performance.

8. Automatic Saw-Frame Movement

The hydraulic system controls the lifting and lowering of the saw frame.

The hydraulic circuit includes pumps, valves, cylinders, tanks, pipelines, and other components that work under electrical control to complete saw-frame movement, workpiece clamping, feeding, and return operations.

9. Automatic Bundle Cutting

The H-330 is equipped with a bundle cutting device.

Within the permitted cutting width and height, multiple workpieces can be arranged in rows and layers for simultaneous cutting. The upper hydraulic clamping system helps secure the bundled material during sawing.

This is especially useful for batch processing of smaller-diameter bars.

10. Automatic Band Break Protection

The machine is equipped with a band saw blade break automatic stop function.

If the saw blade breaks during operation, the machine automatically stops, helping prevent further machine operation under abnormal conditions.

11. Automatic Chip Removal

A passive wire-brush wheel is installed to clean residual chips from the band saw blade.

The cooling pump supplies coolant to help clean the saw teeth and prevent chips from blocking the tooth gullets. This helps improve cutting efficiency and extend band saw blade service life.

12. Automatic and Manual Dual Operation

The H-330 supports both automatic and manual cutting modes.

In manual mode, operators can independently control functions such as:

• Vise clamping and releasing
• Feeding
• Material return
• Main machine operation
• Other machine movements

This makes machine setup, maintenance, and small-batch production more convenient.

Technical Specifications

Customization Options

The H-330 can be configured according to the customer's workpiece dimensions, cutting length, production volume, and automation requirements.

1. Feeding Length Configuration

The standard single feeding length can be set up to 400 mm.

For longer finished lengths, multiple feeding cycles can be used to achieve the required cutting length.

2. Bundle Cutting Configuration

The H-330 comes with a bundle-cutting device.

For customers processing multiple small-diameter bars, the machine can arrange several workpieces within the allowable cutting area and process them simultaneously.

3. Cutting Program Configuration

The PLC system supports one or five groups of cutting data.

This can be useful for production orders involving multiple cutting lengths or different workpiece specifications.

4. Material Feeding System

The standard configuration includes two 600 mm feeding racks.

For customers requiring longer material storage, extended feeding, or connection with other production equipment, the feeding system can be evaluated according to the actual production layout.

5. Production-Line Integration

For higher automation requirements, the H-330 can be evaluated for integration with auxiliary equipment such as:

• Automatic material loading systems
• Extended roller conveyors
• Material storage racks
• Finished-piece collection systems
• Automatic unloading equipment
• Upstream and downstream production equipment

The final automation configuration should be determined according to the customer's material dimensions, cutting length, material weight, production volume, and factory layout.

Application

The H-330 is designed for automated cutting of round materials, plates, pipes, and other ferrous metal workpieces within its cutting capacity.

Steel Bar Cutting

Suitable for repetitive cutting of steel bars into fixed lengths for subsequent machining or production.

Pipe and Tube Cutting
