Types of CNC wire bending machines

A cnc wire bending machine is used to precisely bend metal wires into different geometric shapes and angles. According to how the wire is bent, there are three common types of CNC wire benders: shearing & punching CNC wire bender machines, rotary CNC wire bender machines, and 3D CNC wire bender machines.

• Shearing & punching CNC wire bender machines:

  In general, shearing & punching CNC wire bender machines are equipped with a bending tool that can bend specific complex shapes as required by the customers. First, the workpiece is cut to the desired length and then is bent into the required shape by using the bending tool. The entire process is controlled by a computer. This kind of machine is usually used to create wire forms with fewer bends.

• Rotary CNC wire bender machines:

  Rotary CNC wire bender machines can also be called rotational bender machines, which use a rotary movement to bend the metal wire into specific shapes. Normally, the wire is fixed on the machine first, and then the machine will move and bend the wire around a mandrel or spindle to form arcs or curves. Rotary CNC wire bender machines can be used to create circular, oval, or spiral shapes. They are usually made into complex bends with high precision and consistency.

• 3D CNC wire bender machines:

  3D CNC wire bender machines can also be called three-dimensional CNC wire bender machines. They are digital-controlled machines that can bend metal wire in multiple directions. The advantages of this machine are that it offers a higher level of flexibility and accuracy, making it easier to create complicated and intricate wire forms. In general, 3D CNC wire bender machines are the more advanced option for those needing precise wire bending capabilities and complex design possibilities.

Specifications and Maintenance Requirements for a CNC Wire Bending Machine

• Machine Sizes:

  CNC wire bending machines usually have multiple bar lengths and diameters. The average lengths generally offered are between 1.5-6 meters (5-20 feet) and widths from 3 centimeters (1.2 inches) to 10 centimeters (4 inches).

• Material Thickness Capability:

  Depending on the CNC wire bender model, wire thickness will vary. Wires include stainless steel, carbon steel, copper, aluminum, etc. Generally, the thickness for steel wires is between 2-12 mm (0.08 - 0.47 inches). For other materials, it could range between 0.5-6 mm (0.02-0.24 inches).

• Machine Weight:

  As a general rule, the weight of a CNC wire bending machine increases with its size. A larger machine is heavier and will have a machine weight of approximately 2,000 kg. A smaller machine will be more transportable with a weight of around 300-500 kg. They are also sometimes used in wire bending facilities.

• Bending Radius:

  The machine can bend wires at different radii. This affects the shape of the workpiece as well as the wire material's stress.

• Contours:

  Using the machine after uploading the code helps get complex shapes, like circles, arcs, and polygons. The required shape is entered in the computer control section, followed by the material input section, and then the workpiece is produced.

Maintenance requirements for CNC wire bending machines

It is essential to keep the machine clean. Performing regular inspections is a critical part of the maintenance schedule. Doing a functional test after completing part lubrication is also vital to ensure operational effectiveness and smooth machine use.

During the maintenance and service procedures, safety practices should be prioritized. Ensure that all parts are disconnected from the power cord. Use appropriate tools and protective equipment for any maintenance and lubrication actions.

• Cleaning:

  Ensure any dust, waste or debris removed from the machine area. Use a vacuum cleaner or compressed air pump to ensure all corners and tracks are clean, including the guide rails.

  Keep all containers, pipes, water channels, and cooling systems clean and unclogged.

• Lubrication:

  Regularly apply lubricant to all moving parts. This includes the guide rails, sliding blocks, along with drive chains and gear wheels. Lubricate bent arms and their bearings too. Use a soft rag or cloth to remove the dirt first. Ensure the areas are clean before applying the lubricant. Lubricate the chain with a spray lubricant that will give enough coverage. Use appropriate oils for different components as specified in the machine's manufacturing guidelines.

• Inspection:

  When checking the machine, look at all cables and wires to see if there are signs of wear or tear. Ensure they are in safe operational condition. Check whether all screws and nuts are tight. Look for any signs of abnormal noise or looseness when the machine is in operation and rectify them immediately.

Application scenarios of cnc wire bending machines

• Automotive industry:

  CNC wire benders are used to manufacture different types of automotive parts, like frames and springs. The machines also create exhaust hangers, throttle return springs, clutch springs, and other components.

• Aerospace industry:

  This involves bending wires for the production of lightweight and durable aircraft structures, like brackets, frames, and support components. Many CNC wire bending machines make use of high-precision bends to create aerospace wire forms.

• Electronics manufacturing:

  This involves using wire benders to produce various kinds of electrical connectors, such as coiled leads, terminals, brackets, and mounting hardware.

• Construction industry:

  This involves using CNC wire bending machines to produce reinforcing steel bars (rebar) and wire fences. Such structures are used in construction projects, like commercial, residential, industrial, and infrastructural projects.

• Furniture industry:

  This involves using CNC wire benders to create uniquely designed furniture pieces, such as stands and shelves.

• Medical industry:

  CNC wire bending machines are used to manufacture medical devices, such as catheter components, guidewires, stents, and surgical instruments.

• Robotics and automation:

  CNC wire bending machines are used in making precise wire components, such as sensor housings, robot arms, and custom brackets.

How to Choose CNC Wire Bending Machines

There are a few things business buyers need to consider when shopping for a CNC wire bending machine for sale. They will need to focus on the machine's software, automation features, wire diameter range and bending accuracy. However, it is still important to match the specific qualities of the machines with the needs of the customer's business application.

Choose a machine with an easy-to-learn, user-friendly software interface. Look for software that comes with pre-loaded bending templates for various materials. An advanced CNC wire bending machine can have customizable features that let users create unique templates to suit their specific needs.

When selecting a wire bender machine, consider its level of automation. Does the machine have automatic feeders or quick-change systems that affect? Look for a device with automated features to reduce labor and boost productivity. The automation will minimize the need for manual setup and supervision during operation and reduce the tendency of human error.

Pick a wire bending machine with various wire diameter settings. A versatile machine can easily accommodate most wire thicknesses. This flexibility eliminates the need to purchase multiple bending machines for different wire gauges.

Most businesses need efficient machines that can produce highly accurate bends. Choose a wire bending machine with a consistent repeatability rating of 0.5 mm or better. Superior wire bending accuracy will ensure high precision and quality in all the products made with it.
