CUTTING MACHINES

What are cutting machines?

Cutting machines are designed to cut through different types of metals. These machines use different technologies and cutting principles to deliver accurate and efficient cuts, which makes them relevant across many industries. Cutting machines are typically used in manufacturing, fabrication, construction, and other areas where precise cutting is required.

Definition and function of cutting machines

Cutting machines are used to cut or shape metals using plasma, oxy-fuel (flame), or laser. The process applies heat, energy, or a focused beam to separate the material and create a clean cut edge. Depending on requirements, throughput, and cut complexity, cutting machines can be manual or CNC-controlled.

Types of cutting machines

• Laser cutters: Use high-energy light to cut materials with high accuracy where detail and tight tolerances matter.
• Plasma cutters: Use a high-temperature plasma arc to cut electrically conductive materials such as steel, aluminium, and copper. Known for fast and efficient cutting.
• Waterjet cutters: Use a high-pressure water stream, often with abrasive media, to cut most materials such as steel, wood, and plastics. Suitable for heat-sensitive materials where thermal input can cause distortion.
• Oxy-fuel cutters (flame cutters): Use an oxygen-fuel flame to cut thick plate. Often chosen for rough cutting and heavier material thicknesses.
  

Applications of cutting machines across industries

Cutting machines play a key role in several industries, including:

• Metalworking: Cut and prepare parts accurately for machines, equipment, vehicles, and structural components.
• Automotive: Cut body panels and other components with repeatable accuracy.
• Construction: Cut steel beams, pipes, and panels to support precise and efficient assembly.
• Electronics: Cut small, complex parts where accuracy affects component function.

When you select the right cutting method, your business can achieve accurate, fast, and cost-effective cuts that match your production needs.

Plasma cutters

Plasma cutters are advanced cutting machines that use a high-temperature plasma arc to cut electrically conductive materials such as steel, aluminium, and copper. Many workshops and production environments choose plasma for its speed, accuracy, and flexibility across a wide range of applications.

How does a plasma cutter work?

A plasma cutter creates an electrical channel through superheated, electrically ionised gas plasma. When the plasma contacts an electrically conductive workpiece, it melts the material and blows the molten material away. The system uses a power source to generate the arc and compressed air (or another gas supply, depending on the setup) to remove molten material and support a clean cut.

Advantages of using a plasma cutter

Plasma cutters offer several advantages for many cutting tasks:

• Precision: Produces precise cuts with smooth edges, which supports parts where detail and accuracy matter.
• Speed: Cuts faster than many oxy-fuel and waterjet processes in relevant thickness ranges, improving throughput.
• Versatility: Handles a wide range of thicknesses and is suitable for many different production tasks.

Typical uses for plasma cutters

Plasma cutters are used across industries due to their flexibility and cutting performance. Common applications include:

• Metalworking: Cutting accurate parts for products and components.
• Automotive: Cutting body parts, chassis components, and other parts that require consistency and durability.
• Construction: Cutting beams, plates, and pipes for buildings and infrastructure.

Advantages of buying used cutting machines

Investing in a new cutting machine can make sense, but used machines can be a cost-effective option without sacrificing performance when selected correctly. Used machines can give access to advanced features at a lower investment level than new equipment. Key benefits include:

Financial benefits

The most obvious advantage is lower cost. Used machines typically cost a fraction of a comparable new model, which frees budget for consumables, setup, or other production needs. This can be particularly relevant for small and medium-sized businesses.

Environmental benefits

Buying used machines extends the service life of existing equipment and reduces demand for new resources and production. For companies that track sustainability initiatives, this supports responsible purchasing.

Quality control

When you buy used cutting machines from a reliable dealer like Sandfeld, you can expect the machine to be inspected and tested to confirm condition and performance. Check machine history and maintenance records, and verify the control to reduce risk and avoid unexpected downtime.

Faster delivery

Used machines are often available faster, because you typically wait for preparation and commissioning rather than manufacturing lead times. That helps you start production sooner and maintain throughput when capacity is critical.

Tips for choosing the right cutting machine

The right cutting machine depends on your materials, production volume, and required cut quality. Use the points below to support your decision.

Assess your requirements and applications

Start by defining what you need and which materials you plan to cut. Consider thickness, material type, and whether you need a manual or automated solution. For example, a plasma cutter can suit the cutting of thicker metal plates, while a laser cutter may be a better match for precision work and complex shapes.

Compare machine types and key features

Compare cutting capacity, speed, accuracy, and ease of operation. Some machines fit specific tasks better than others. For example, a waterjet cutter can be suitable for heat-sensitive materials, while oxy-fuel cutting is often used for rough cutting of thick plate.

Consider budget and total cost of ownership

Budget matters, but you should also evaluate total cost of ownership, including maintenance, spare parts, and operating costs. In many cases, a used cutting machine that meets your requirements provides a strong cost-to-performance ratio.

Consult specialists

If you are unsure which cutting machine fits your production needs, specialist guidance helps. Sandfeld provides advice to match machine type and configuration to your requirements, so you can make an informed decision.

FAQ

What is the difference between a plasma cutter and a laser cutter?

A plasma cutter uses a high-temperature plasma arc to cut electrically conductive materials such as steel, aluminium, and copper.. A laser cutter uses a focused light beam to cut with high accuracy and finish. Laser cutting is typically chosen for precision work, where detail and tight tolerances matter.

What are the benefits of buying used cutting machines?

Used cutting machines can reduce investment cost compared with new equipment. When the machine is well maintained and inspected, it can deliver reliable performance and cut quality. Used machines can also provide access to advanced features at a lower price point.

How do you choose the right cutting machine for your business?

Start with materials, required accuracy, cutting speed, thickness range, and production volume. Then compare machine types such as plasma, or laser and evaluate the relevant features. Include both purchase price and total cost of ownership to select the most suitable solution.

What maintenance tips apply to plasma cutters?

Carry out regular inspections for wear, leaks, and loose connections. Keep the work area and machine clean by removing dust and debris. Service moving components according to the manufacturer’s guidelines and replace consumables when needed. Ensure operators follow safety procedures and receive proper training.
