GZ4250 Fully Automatic Horizontal Band Saw For Metal Bar Cutting Production

Product Introduction

The GZ4250 Fully Automatic CNC Horizontal Band Saw Machine is designed for high-efficiency and continuous metal cutting applications. With an integrated PLC control system, touchscreen HMI, hydraulic feeding, hydraulic clamping, and grating scale positioning, the machine can automatically complete material feeding, clamping, cutting, and counting according to preset parameters.

With a maximum cutting capacity of Ø500 mm for round materials and 500 mm for rectangular materials, the GZ4250 is suitable for cutting various types of steel, bars, plates, profiles, and other metal materials.

The machine adopts a main and auxiliary column structure, rigid welded construction, hydraulic variable-speed feeding, and a stable worm gear transmission system to provide reliable cutting performance during continuous production.

For batch processing, the machine can perform automatic multi-cycle feeding and bundle cutting, significantly reducing operator workload while improving production consistency and material utilization.

Automation Features

1. Automatic CNC Cutting Cycle

Operators can preset the required cutting length and quantity through the touchscreen. After the machine returns to its reference position, the automatic cutting cycle starts and continues until the preset quantity is completed.

The machine automatically stops after completing the programmed cutting quantity, reducing manual intervention during production.

2. Automatic Hydraulic Feeding

The rear feeding system uses hydraulic feeding combined with grating scale positioning to achieve accurate material positioning.

A single feeding stroke can be set from 2–600 mm. When a longer cutting length is required, multiple feeding cycles can be automatically performed.

3. Automatic Hydraulic Clamping

The workpiece is clamped hydraulically to improve stability during cutting.

The machine uses front and rear clamping arrangements so that at least one set of jaws remains engaged during the cutting process, helping prevent material movement and improving cutting stability.

4. Automatic Counting and Production Management

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

Operators can set cutting data and quantities directly through the touchscreen, reducing repetitive manual operations.

5. Bundle Cutting Capability

The GZ4250 can be equipped with a bundle cutting device for simultaneously cutting multiple workpieces.

Multiple pieces can be arranged within the specified width and height range, making the machine suitable for higher-volume production applications.

6. Automatic Chip Removal

A passive wire brush chip-removal system cleans chips from the band saw blade. The cooling system helps wash away chips from the tooth gullets, reducing chip accumulation and helping extend blade service life.

7. Automatic Safety Protection

The machine is equipped with automatic blade-break detection and shutdown. When the band saw blade breaks, the machine automatically stops to help protect the equipment and improve operator safety.
