CNC Automatic Horizontal Band Saw For Metal Processing Industry Cutting

The GZ4240 CNC Automatic Horizontal Band Saw is a high-performance cutting solution designed specifically for the metal processing industry. With a cutting capacity of φ400 mm for round materials and 400 mm for square materials, this heavy-duty band saw is ideal for processing carbon steel, alloy steel, stainless steel, tool steel, and other ferrous metals commonly used in manufacturing and fabrication operations.

Built with a robust dual-column structure and steel plate welded frame that has undergone vibration aging treatment, the GZ4240 delivers exceptional stability and cutting accuracy for demanding metal processing applications. The hydraulic feeding system with optical ruler positioning ensures precise material indexing with ±0.2 mm cutting length tolerance, while the bundle cutting capability allows multiple materials to be cut simultaneously for increased productivity.

The machine features a PLC control system with color touch screen interface, offering both manual and automatic operation modes. With four-speed blade selection (25/35/50/65 m/min), hydraulic infinitely variable feed rate control, and automatic blade break detection, the GZ4240 combines versatility, efficiency, and safety for a wide range of metal cutting applications.

• Q1: What metals can the GZ4240 cut?
  A: This band saw is designed for cutting carbon steel, alloy steel, stainless steel, tool steel, and other ferrous metals commonly used in metal processing and fabrication operations.

• Q2: What is the cutting accuracy?
  A: The GZ4240 delivers cutting length tolerance of ±0.2 mm with optical ruler positioning, ensuring consistent part dimensions for downstream operations.

• Q3: Can the machine cut multiple bars at once?
  A: Yes, the machine is equipped with a bundle cutting device. Within the clamping width and height limits, multiple metal bars can be placed side by side or in multiple layers for simultaneous cutting.

• Q4: What are the blade speed options?
  A: The machine offers four blade speeds: 25, 35, 50, and 65 m/min, allowing optimal cutting parameters for different metal types and hardness levels.

• Q5: How does the feeding system work?
  A: The hydraulic feeding system with optical ruler positioning provides accurate material indexing. Single feed stroke is up to 600 mm, with multiple feeds available for longer workpieces.

• Q6: Can the machine be operated manually for small batches?
  A: Yes, the GZ4240 features both manual and automatic operation modes. Manual mode is ideal for small batch or single piece cutting, custom fabrication, and specialty materials.
