CNC Plasma Tube Cutter: The Ultimate FAQ Guide

It is essential to know the details of the CNC plasma tube cutter before buying it for your business.

Here is a comprehensive FAQ guide regarding CNC plasma rotary tube cutters.

It includes its definition, the plasma cutting process, benefits, etc.

What is a CNC Plasma Tube Cutter?

A plasma cutter is a metal cutting machine that uses various working gases to cut sheet metal and metal pipes of various thicknesses.

It is a useful power tool for metal manufacturing.

A plasma cutter is a powerful tool that processes metal materials using plasma cutting technology.cnc plasma tube cutting machine supplier

CNC plasma tube cutting machine

It can cut all sorts of metals that are difficult to cut with oxygen, notably non-ferrous metals, using various working gases (stainless steel, aluminum, copper, titanium, nickel).

The flame cutting machine is the polar opposite of the plasma cutting machine, and the two cutting procedures are distinct.

Plasma Cutting Process

Plasma cutting is a manufacturing technology that uses the warmth of a high-temperature plasma arc to partially or melt (and vaporize) the metal at the workpiece’s cut, then removes the molten metal using the high-speed plasma’s momentum.

Plasma cutting with multiple operating gases may cut a wide range of metals, including non-ferrous metals, that are difficult to cut with oxygen (stainless steel, aluminum, copper, titanium, nickel).

The cutting effect is superior, and the main benefit is that the metal thickness is reduced.

New fine plasma or high-precision plasma technologies have been widely deployed in recent years, with excellent results.

The quality of the workpiece’s cutting surface is greatly improved by increasing the design of the cutting moment.

The verticality of the shaft edge can reach 0-1.5°, which is very advantageous for cutting thick plates.

The electrode life has been boosted by several times thanks to the improved cutting gun.

However, because the distance between the cutting torch and the steel plate is so great, the cutting torch’s height sensor must be more sensitive, and the cutting torch must react faster.

Plasma cutting of 4-30 mm steel plates is thus an appropriate approach for avoiding the drawbacks of low oxygen and oxygen deprivation, substantial deformation, severe cutting, and severe slagging.

Manual and semi-automatic cutting is more prevalent in some small and medium-sized businesses and some important businesses.

Steel is cut in enormous quantities in the machinery business.

The demands for work efficiency and product quality in sheet metal cutting are growing in tandem with the development of the contemporary machinery sector.

As a result, the market potential for CNC plasma cutting machines remains enormous, and the market outlook is somewhat positive.

What are the Key Features of the Plasma Tube Cutter?

A plasma tube cutter machine has the following important features:

  • Tees, miters, saddles, alignment offsets, numerous intersections, elbow supports, gusset slots; round, rectangular, saw cut, intersecting pipe holes, re-pads having axial offsets and baseline or working point offsets, and other types of intersecting cuts are all possible with the CNC plasma rotary tube cutter.
  • Precise casting parts and careful manufacturing and testing procedures ensure high accuracy, dependability, and longevity.
  • It can produce CNC codes from AutoCAD drawings, saving operators and engineers time. It is integrated with specialist programming and computation modules for sophisticated massive steel structure building. IGES, DXF, SAT, and STL files are all supported by these modules.
  • The out-of-round pipe is compensated vertically using an automatic, servo-driven height measuring system. For loading and unloading, there are in-feed and out-feed conveyors available.
What are the Parts of a CNC Plasma Tube Cutter?

The CNC is a controller developed for machine tools with a specific interface panel and a particularly designed management console.

It might even be as simple as using a Windows laptop computer to run a specific package program and interact with the machine discs via the LAN connector.

A laptop computer or personal computer is used as the controller for various entry-level machinery, HVAC equipment, and even some precision unitized machines.

The movement of the torch is regulated by the CNC to cut components from the plate. The half outlines are described in an area program, which is sometimes just a computer file with “M-codes” and “G-codes” to show the torch on and off.

Half programs are occasionally developed by a software called a “post-processor,” which takes a section of pure mathematics from a CAD file and converts it into M-codes and G-codes that the CNC can read.

A driving system, which includes drive amplifiers, motors, encoders, and cables, is also required for a CNC plasma cutter.

A minimum of two motors will be used.

Every motor has a piece of electronic drive equipment that converts a low-power signal from the CNC into a higher-powered signal to move the motor.

Every axis contains a feedback system, occasionally an encoder, that generates a digital signal that indicates how far the axis has moved.

Cables connect the electrical equipment to the motor and return the position indications from the encoder to the CNC.

How Do CNC Plasma Rotary Tube Cutters Work?

Plasma cutters come in many different shapes and sizes.

Large format CNC plasma cutting tables with robotic arms for accurate cutting is available, as are streamlined portable plasma cutters for hand workshops.

CNC plasma pipe cutting machine

Regardless of size, all plasma cutters operate on the same principle and have similar structural construction.

When the plasma cutting machine is turned on, compressed gas such as nitrogen, argon, or oxygen is released through a small pipe.

In the middle of the pipe, a negative electrode is put.

A conductive loop is formed when power is applied to the negative electrode.

The nozzle opening makes contact with the metal.

A high-energy electric spark is produced between the electrode and the metal.

The electric spark warms the inert gas as it passes through the pipeline, bringing it to the fourth state of matter.

This reaction generates a plasma stream with a temperature of roughly 16,649 degrees Celsius and a flow rate of 6,096 meters per second, capable of rapidly turning metal into slag.

The plasma itself conducts an electric current.

The arc generating cycle continues as long as the electrode is energized and the plasma is in contact with the metal.

The cutting machine nozzle is fitted with another set of pipes to ensure this contact while preventing damage caused by oxidation and other unknown plasma properties.

To protect the cutting area, these pipes continuously emit protective gas.

The shielding gas’s pressure can efficiently control the columnar plasma’s radius.

The plasma pipe cutter should be installed away from large-scale electrical equipment and regions where there is a lot of electrical interference.

How to Setup a CNC Plasma Tube Cutter?

Plasma tube cutters produce a lot of dust in the everyday production process, so we need to build robust ventilation mechanisms in the apparatus workplace to exhaust the smoke produced during the CNC plasma pipe cutter cutting process.

Check that all of the gear switches are off and that the rotary switch at the back of the plasma power source is in the horizontal position before turning it on.

  • Turn on the main power switch cabinet’s power supply to provide the two wires’ power.
  • Turn on the circuit breaker in the machine’s control box.
  • The primary interface should appear on the monitor after turning on the power supply of the CNC controller with the key switch.
  • Turn the back of the plasma input supply’s rotating switch 90 degrees to the vertical position. The power indicator on the front of the plasma power supply should be on at this point.
  • Turn the air compressor on (flow rate 1 m3/min), and adjust the air compressor pressure control switch so that the compressor output air pressure is between 6.1 and 8.2 bar; if the air pressure is less than 6.1 bar, the air pressure will be lowered during cutting, resulting in better cutting quality. Unstable; if the air pressure is more than 8.3Bar, the air filter on the plasma power supply will be damaged.
  • Maintain a pressure of 5.5-6.0 Bar by adjusting the air pressure control knob on the plasma power supply.
  • To ensure that the air pressure does not fall below 5 bar, turn the plasma power supply current alteration test knob to the gas test setting.
  • When the pressure is less than 5 bar, the cutting quality suffers significantly, and the plasma power supply may even fail.

CNC plasma tube cutting machine operating

A multi-stage combination filtering system should be present in front of the plasma power source if the operating environment cannot ensure the cleanliness of the supply air supply.

Otherwise, air contaminated with oil, moisture, and dust will result in arcing failure and harm to the cutting torch while cutting.

The start-up process is complete if plasma cutting is employed.

How to Maintain a CNC Plasma Pipe Cutting Machine?
  • Ascertain proper pressure and flow
  • Use a Tangent That Is Reasonable
  • Perforation and cutting thickness must be within the plasma cutting system’s allowable range.
  • Do not overburden the nozzle.
  • Maintain a clean and dry plasma gas
What are the Precautions to Consider While Using a CNC Plasma Pipe Cutter?

Clean the dust in the pipe cutting machine and the dirt on the parts on a regular basis while functioning, and check whether the wires are aging.

The ground wire and the workpiece make poor contact.

Before cutting, grounding is an essential step.

Insulation on the workpiece’s surface and long-term use of a ground wire with significant aging.

For example, it will result in poor contact between the ground wire and the workpiece if a dedicated grounding tool is not employed.

Special grounding equipment should be used, and any insulation between the grounding wire and the workpiece’s surface should be checked.

Aging grounding wires should be avoided.

The plasma pipe cutting machine must first spark the arc if the spark generator cannot switch it off automatically.

  • To provide proper gas pressure and plasma flow. The right gas pressure and plasma flow are critical for the long life of consumable parts. The electrode’s life will be substantially reduced if the air pressure is too high; the nozzle’s life will be harmed if the air pressure is too low.
  • Maintain a safe cutting distance. Use an appropriate cutting distance according to the instruction manual’s guidelines. Cutting distance refers to the distance between the cutter nozzle and the workpiece’s base. When perforating, utilize double the typical cutting distance or transmit with the plasma arc. The highest point is possible.
  • The perforation thickness must be within the machine system’s permitted range. The plasma cutter will not be able to perforate steel plates that are thicker than the working thickness. Penetration thickness is usually 1/2 of the cutting thickness.
  • Make sure the nozzle isn’t overloaded. The nozzle will be damaged fast if it is overloaded (that is, the operating current of the nozzle is exceeded). The current intensity should be at least 95% of the nozzle’s operating current. For instance, a 100A nozzle’s current intensity must be tuned to 95A.
  • Maintain a clean and dry plasma gas. To function correctly, the plasma system requires dry and clean plasma gas. Dirty gas is a common issue in the gas compression system, reducing the life of consumable parts and causing anomalous damage.
  • Setting the cutting torch in the test state and placing a mirror underneath it to consume the gas in the cutting torch is one way to test the gas quality. If water vapor and mist emerge on the mirror, you must determine the cause and repair the problem.
  • Rather than perforating, plasma cutting must begin as close to the edge as practicable. Using the edge as a starting point will help the consumable parts last longer. Before igniting the plasma arc, you should point the nozzle directly towards the edge of the workpiece.
  • Reduce time spent on “arc starting (or arc guiding).” When the arc starts, the nozzle and electrode are immediately consumed. The cutting torch should be set within walking distance of the metal to be cut before beginning.
  • Slag on the protective shell should be removed.
