Product Introduction

The GZ4232 CNC Automatic Horizontal Band Saw Machine is designed for efficient and precise cutting of medium-sized round bars, pipes, plates, and various ferrous metal materials. With a maximum cutting capacity of Ø320 mm for round material and 320 mm for plate material, it is suitable for continuous and batch cutting applications.

The machine integrates mechanical, hydraulic, electrical and PLC control systems to provide automatic clamping, automatic feeding, hydraulic cutting-feed control, automatic counting and automatic saw-frame return. Its combination of a touchscreen interface and push-button controls makes operation simple and flexible.

A rear hydraulic feeding system with grating-scale positioning enables automatic length control, while multiple feeding cycles can be used for workpieces longer than the single-feed stroke. The machine can achieve a finished cutting-length accuracy of ±0.2 mm, with cutting squareness meeting the applicable national standard stated in the technical documentation.

Automation Features

1. CNC Automatic Cutting

The GZ4232 uses a PLC control system combined with a touchscreen HMI to automate the cutting cycle. Operators can set the required cutting length and quantity, return the machine to its reference position, and start automatic cutting. Once the preset quantity has been completed, the machine automatically stops.

2. Automatic Hydraulic Clamping

The machine uses hydraulic clamping to secure the workpiece during cutting. The front and rear clamping systems work together to maintain stable workpiece positioning and reduce movement during the cutting process.

3. Automatic Feeding

The rear feeding system uses hydraulic feeding and grating-scale positioning for controlled material positioning.

The single feeding stroke can be set from 2 to 400 mm. When a longer feeding length is required, multiple feeding cycles can be performed automatically.

4. Hydraulic Infinitely Variable Feed Control

The saw-blade feed movement is controlled hydraulically. The adjustable feed system allows the cutting feed rate to be adapted to different material conditions and cutting requirements.

5. Automatic Saw-Frame Return

After the cutting process is completed, the saw frame automatically returns quickly, helping reduce non-cutting time and improve production efficiency.

6. Automatic Cutting Quantity Control

Operators can set the required cutting length and quantity through the HMI. The control system automatically counts completed pieces and stops the machine after the preset quantity has been reached.

7. Manual & Automatic Operation

The machine supports both automatic and manual cutting modes. Manual controls allow individual machine movements to be operated when small quantities of material or maintenance operations are required.

8. Automatic Chip Removal

A wire-brush chip removal system cleans residual chips from the band saw blade. Coolant supplied by the cooling pump helps remove chips from the blade teeth, reducing tooth-gullet blockage and helping extend blade service life.

9. Safety Protection

The machine includes an automatic stop function when blade breakage is detected. The main electrical system is also equipped with circuit protection, while the hydraulic control system uses a 24V safety-control voltage.

Technical Specifications

Customization Options

The GZ4232 can be configured according to different production requirements. Depending on the material, workpiece dimensions, cutting quantity and automation requirements, customers can discuss the following options with the manufacturer:

1. Cutting Parameters

The machine provides four selectable band-saw speeds:

30 / 45 / 60 / 80 m/min

This allows the cutting speed to be selected according to different material and production requirements.

2. Feeding Requirements

The standard feeding system provides a 2–400 mm adjustable single-feed stroke. Multiple feeding cycles can be used when longer cutting lengths are required.

3. Control System Configuration

The machine uses PLC control with touchscreen and push-button operation. The technical documentation specifies components from brands such as Inovance, Weinview/Kunlun Tongtai, Tengen, Autonics and WanHao for different electrical and control functions. Component brands and specifications may be subject to product upgrades.

4. Material & Cutting Application

Configuration can be evaluated according to:

• Round bar diameter
• Pipe dimensions
• Plate dimensions
• Material type
• Required cutting length
• Required production quantity
• Single-piece or batch production
• Automatic or manual operation requirements

For special applications, the machine configuration should be confirmed based on the customer's actual cutting conditions.

5. Production Line Integration

For customers with continuous or high-volume production requirements, the feeding and material-handling configuration can be evaluated according to the production process.

Customization should be confirmed with the manufacturer before quotation and production.

Application

The GZ4232 is designed for cutting medium-sized round bars, pipes, plates and various ferrous metal materials. Its automatic feeding, clamping and cutting functions make it particularly suitable for repetitive and batch-production applications.

Typical Applications

Bearing Manufacturing

Suitable for cutting metal stock used in bearing production.

Automotive Parts Manufacturing

Suitable for repetitive cutting of metal materials used for automotive components.

Standard Parts Manufacturing

Automatic feeding and quantity control are useful for high-volume cutting operations.

Metal Bar & Tube Processing

The Ø320 mm maximum round cutting capacity allows the machine to process a wide range of medium-sized round materials.

Plate Cutting

The machine can cut plate materials up to 320 mm within its specified cutting capacity.

Batch Production

Automatic length setting, feeding, counting and cutting make the GZ4232 suitable for continuous and repetitive production.

FAQ

Q1: What is your factory acceptance test method?

A: You can send us sample material to be cut, and we will perform a test cut using our machine. After the test is complete, we will provide you with detailed cutting data. (We will also send you a video of the machine cutting operation for your confirmation.)

Q2: Does the band saw blade have any international certifications?

A: Yes, we have obtained CE, ISO international

Q3: How about your delivery time?

A: Generally, it will take 7-60 work days after receiving your order. The specific delivery time depends on the items and the quantity of your order.

Q4:How does the machine improve cutting stability?

A:The machine uses a rigid welded saw frame, precision-ground cylindrical guiding components, adjustable band-saw guides, and a transmission system that has undergone precision balancing. These features are designed to reduce vibration and improve cutting stability.

Q5:Can it cut multiple pieces of material at the same time?

A:Yes. The technical documentation states that the automatic machine can be used for bundle cutting, with multiple pieces arranged within the permitted width and height ranges. An upper clamping cylinder helps secure the material during cutting.
