The GZ4232 CNC Band Saw Machine is a CNC-controlled horizontal metal band saw designed for efficient and accurate cutting of small and medium-sized bars, tubes, and metal plates.

With a maximum cutting capacity of Ø320 mm for round materials and 320 mm for plate materials, the GZ4232 is suitable for a wide range of ferrous metal cutting applications. The machine combines PLC control, touch-screen operation, hydraulic clamping, hydraulic stepless feed control, and grating-scale positioning to provide stable and repeatable cutting performance.

Designed for batch production and continuous cutting, the GZ4232 can automatically complete material clamping, feeding, sawing, and saw-frame rapid return after cutting. Operators can set the required cutting length and quantity through the touch screen, after which the machine automatically performs the programmed cutting cycle and stops when the preset quantity has been completed.
The machine uses a worm gear transmission system, precision-ground cylindrical guide structure, adjustable blade guides, and front/rear workpiece clamping, providing a stable cutting environment for both individual and bundled materials.

With a cut-to-length accuracy of ±0.2 mm, the GZ4232 offers a practical solution for manufacturers looking to improve cutting consistency, reduce manual operation, and increase productivity in metal processing.

Key Features

1. CNC Automatic Cutting for Batch Production

Operators can enter the required cutting length and quantity through the touch screen. Once the machine is returned to its reference position and automatic operation is started, it can automatically perform the programmed cutting cycle.

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

2. Hydraulic Stepless Feeding for Flexible Cutting Control

The saw blade feeding system uses hydraulic control with stepless speed adjustment.

Instead of using a fixed feed speed, operators can continuously adjust the blade feed according to the material and cutting conditions.

The hydraulic system operates at a pressure of 2–2.5 MPa, providing controlled blade feeding throughout the cutting process.

3. Grating-Scale Positioning for Accurate Material Feeding

The grating scale provides position feedback during material feeding, helping control the feeding distance and improve repeatability.

The single feeding stroke can be set from 2 to 400 mm. When a required length exceeds 400 mm, the machine can perform multiple feeding operations to achieve the desired cutting length.

4. ±0.2 mm Cut-to-Length Accuracy

According to the technical documentation, the finished cut-to-length accuracy can reach ±0.2 mm, while the cutting squareness of the cut surface meets the applicable national standard.

The combination of grating-scale positioning, stable feeding, rigid machine structure, precision blade guides, and hydraulic control contributes to consistent cutting results.

5. Hydraulic Clamping for Stable Workpiece Holding

The front and rear clamping jaws work together during the cutting process. At least one set of jaws remains clamped while the machine is operating, helping prevent the workpiece from moving during sawing.
The machine also incorporates upper clamping devices that automatically move according to the sawing process.

6. Suitable for Bundled Material Cutting

Multiple pieces of material can be arranged together within the permitted width and height and cut as a bundle.

This can significantly increase productivity when processing large quantities of small-diameter bars or similar workpieces.

7. High-Rigidity Machine Structure

The machine uses a main and auxiliary column structure, together with a cast-iron machine bed and welded steel saw frame.

The saw frame is reinforced with structural ribs, providing a rigid foundation for the blade drive and guide system.

8. Precision Blade Guide System

The guide arms can be moved along the dovetail structure according to workpiece dimensions.

The guide system helps keep the blade properly aligned and reduce vibration during cutting.

The technical documentation also states that the high-precision saw wheels and reinforced adjustable tungsten-carbide clamping pieces help ensure cutting accuracy.

9. Four-Step Blade Speed Adjustment

The GZ4232 provides four blade speed settings:

30 / 45 / 60 / 80 m/min

This allows operators to select an appropriate blade speed according to material type, workpiece dimensions, and cutting requirements.

10. Powerful Worm Gear Transmission

The main transmission uses a worm gear reduction system driven by a 4.0 kW main motor.

The motor transmits power through the belt and worm gear box to the driving wheel, which then drives the saw blade.

FAQ

Q1: How about the payment term?

A: T/T 30% deposit, 70% of balance paid before shipment. (For other payment methods please contact our sales team)

Q2: Are you a manufacturer or a trading company?

A: We are a professional manufacturer of saw blade grinders. We have a 30,000 square meter factory and a team of dedicated technicians specializing in design, manufacturing, and sales.

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 accurate is the feeding system?

A: The rear feeding system uses grating-scale positioning. The single feeding stroke can be set from 2–400 mm, and multiple feeding operations can be used when a longer feeding distance is required.

Q5:Can the GZ4232 cut multiple pieces at the same time?

A:Yes. Within the specified cutting range, multiple pieces can be arranged into a bundle for simultaneous cutting. This is particularly useful for high-volume production of smaller-section materials.
