Single-side automatic loading and unloading

A gantry loading and unloading system has been added to replace manual loading, and the material selection and loading is autonomous, with high efficiency, mechanical execution, good stability, and no mistakes.​

PUNCHING AND LASER COMBINED MACHINE

On the basis of CNC punching machine, laser cutting function is added. Punching is done first and then cutting. There is no need to process on laser cutting machine first. It is highly efficient and can process small workpieces. It can also reduce equipment cost, equipment footprint, production cost and improve production efficiency.

Turret device

The turret features a thick sleeve structure that increases tool durability and life. The robust design ensures stable guiding accuracy, minimizes wear during high-speed operation, and maintains alignment and concentricity for smooth tool changes. High-strength materials resist torque and stress for consistent performance even under heavy loads.

Frequently Asked Questions

Servo punching machines have obvious advantages over hydraulic and mechanical punching machines. First, the servo drive system can provide higher speed and precision, which will greatly improve production efficiency and is suitable for workpiece processing that requires fast response and high precision. Compared with hydraulic punching machines, servo punching machines are not only slower than servo machines, but also energy-saving and environmentally friendly, reducing the maintenance and cleaning of hydraulic oil and reducing operating costs. Mechanical punching machines are susceptible to wear and tear, consume a lot of energy, and long-term use will affect precision and efficiency.

  • Small workpiece production: When producing small workpieces, punching or forming can be performed directly through the punch press, eliminating additional processes such as bending and improving production efficiency.
  • Mesh plate processing: Punching machines are very suitable for mass production such as mesh plates, and can quickly and accurately complete hole punching, especially for scenes that require high production efficiency.
  • Complex graphics or lines: If the workpiece requires fine lines, laser cutting is more suitable because it can handle more complex graphics and fine lines. For cutting large areas or simple shapes, punching machines are a more efficient choice.

Punching machines are suitable for large batches, small workpieces, mesh plates, and forming processes, while laser cutting is more suitable for fine lines and complex graphics.

Burrs are produced after both stamping and cutting. Here is an explanation of the generation of burrs

  • Stamping: During the stamping process, burrs usually appear on the back of the material, that is, the position where the punch leaves. Softer metals and thicker materials are prone to larger burrs.
  • Cutting: Burrs may also be produced during the cutting process, especially mechanical cutting and laser cutting, and thicker metals are prone to burrs.

The impact of burrs:

Burrs can affect product appearance, precision, function and safety, increase production costs and interfere with subsequent processes.
