Buying guides for cutting machines to make the right decision.

Which machine to use for cutting?

The cutting head of a cutting machine is held in place by a gantry attached to the machine’s table. Plates, sheets, profiles, and panels may all be cut using these machines. Laser, water jet, and plasma cutting are only a few examples of cutting technology. The material to be cut and the manufacturing requirements will determine the technology used.

What factors should be considered while purchasing a cutting machine?

A cutting machine (tronzadora) must be chosen based on the substance or materials to be cut’s fundamental properties. Several other types of cutting machines out there don’t employ the same technology, such as metal, plastic, cloth, and wood cutting machines.

Additionally, the machine must be able to accomplish the planned thickness of the cut, and the table must be able to accommodate the dimensions of the parts to be cut. Cutting technology must be selected based on the required accuracy, quality, and productivity. Finally.

How would you characterize the leading-edge technologies that are now available?

Cutting metals may be done using laser, plasma, EDM, or oxyfuel cutting techniques. Water jet cutting may be used to cut thick materials, whether metallic or non-metallic. The knife cutting machine is an excellent option for cutting flexible materials like fabric, leather, flexible plastic, paper, or cardboard.

When should you use a laser cutter?

With mirrors or optical fibers, a laser beam may be directed into a cutting path and provide the heat necessary for cutting. Depending on the laser, they can cut a variety of materials.

  • Cutting materials including plastic, foam, wood, glass, and textiles are most suited for CO2 laser cutting equipment. Reflective metals such as copper and brass cannot be cut with this tool.
  • Most often utilized for sheet metal and various polymers, fiber lasers offer a greater cutting power.

As long as the laser is configured correctly, it is possible to work with various materials without changing equipment. Because of its precision, this is the cut of choice for intricate shapes. Depending on the material being cut, the cutting speed changes. Automated laser cutting equipment reduces the likelihood of accidents since they need minimal human interaction to use in cutting center (Centro de corte).

This machine’s biggest drawback is its very shallow cutting depth (less than 25 microns). Laser cutting is used mainly for sheet metal production, particularly in the automobile sector, and for the fabrication of metal frames for electrical cabinets, computers, and other devices, such as printers. Plasma cutting is the best option for items with more than 25 mm thickness.

Warping may occur due to the laser beam’s high heat output to a tiny region. Because laser cutting emits gaseous emissions, a well-ventilated space is necessary while using the equipment.

When should you use a plasma cutter?

Steel, stainless steel, aluminum, brass, copper, and other non-ferrous metals up to a maximum thickness of 160 mm cannot be cut using plasma cutting equipment.

Compared to laser and oxyfuel cutting, plasma cutting is faster for thick or medium-thickness plates. When it comes to cutting heavy metal plates, plasma cutting is ideal.

It’s important to note that plasma cutting and TIG welding work on the same basic concept: ionized gas injected between the electrode and the material to be cut. Various gases are used in plasma cutting; the most frequent are argon, nitrogen, oxygen, and hydrogen. No matter what gas is utilized, the nozzle and electrode will eventually need to be changed. Portable models may be used for occasional usage.

Plasma cutting should only be done in well-ventilated places or outdoors because of the poisonous fumes from vaporized metal.

Oxyfuel cutting devices-

Oxyfuel cutting devices cut molten metal with a stream of pure oxygen. Only particular kinds of steel may be utilized for this method, but it has the benefit of cutting plates as thick as 400 mm.

It’s a procedure that takes a long time. On the other hand, some machines have several oxyfuel torches that operate concurrently, allowing larger output capacity.

To use an EDM cutting machine, you need to know when to do so.

Conductive materials are machined using EDM machines, also known as spark discharge cutting machines. They can cut components up to a maximum thickness of 300 mm with extreme accuracy. Electrical discharges remove material from the component while the process runs. This method is best suited to cutting tough metals, such as hardened steel.
