WaterJet Cutting Versus Laser Cutting

Waterjet Cutting Machine

Water jet cutting and laser jet cutting are two of the most well known and widely used material cutting methods. With respect to the material in question and the result, you desire to have, one of them is going to be highly appropriate for a given application. Paramount to optimizing the benefits these two material cutting methods can bring lies on how profound we understand their fundamental differences, most especially in terms of the processes involved and the materials they are known to work well with.

Water Jet Cutting Machine

Unlike laser cutters, waterjet cutter machines utilize pressurized water to cut through any given material. In order to further intensify its cutting power, abrasive materials like aluminum oxide and garnets can be added to the pressurized water.

The working idea behind waterjet cutter was inspired by the erosion of soil in nature, just that it is done with so much more intensity and at a higher concentration and speeds. Imagine, an extremely powerful, high-pressure water pump forcing water through rigid hoses. This will result in a strong jet of water. For water jet, It is typical for them to produce an impressive output of 4 to 7 kilowatts of power. The water jet is unlike laser cutters. The source or point of origin of the laser is coming inside the machine itself, the pump and the work area are not together but separate.

Applications and Materials

Water jets are capable of cutting through almost every imaginable material there is, including a combination of 2 or more materials. Even though this method can cut through a wide spectrum of materials, delamination is one of its possible downsides. It can also handle your needs for 3D material cutting. Additionally, the cutting of materials that gives you limited access to the target area is possible but presents great challenge or difficulty.

Water jet technology allows you to carry out structuring, cutting ablation. It lets you handle several materials including ceramics, stone, and even thick metals. Materials with a thickness level of 0.4 to inches can benefit from the use of the water jet method.

LaserJet Cutting

Laser cutting machines solely relies on a gas laser for energy, typically CO2. The CO2 gas is going to be transmitted via a beam, under the guidance of a mirror before it is finally directed at the material.

The source of the CO2 laser is situated inside the machine itself. As for the beam, this can come in the range of 1500 2600 watts of power. If you want to consider the use of laser cutters, applications, materials, safety, and precision are a few of the important factors that you’ll need to take into account.

Applications and Materials

Laser cutters can handle the cutting of a variety of materials. This would include glass, plastic, wood, and all kinds of metals, except for reflective metals. In case that the material is a combination of metals, and have different melting points, it will bring along a certain level of challenge to cut through it.

Sandwich structures that come with cavities may never be completely cut with a CO2 laser. The same is also true for materials that have limited access. As for 3D material cutting, it also presents difficulty in managing due to the rigid beam guidance.

Top 3 Common Misconceptions on CNC Plasma Kits in Australia

Best CNC Cutting Machine

Managers in charged with overseeing CNC plasma kits in Australia manufacturing firms usually started their careers in other areas first. Nothing wrong with that, but they have very limited exposure and experience in the manufacturing space.

Thus, we can’t expect them to always have a profound understanding of what is going on inside the shop. So, when hurdles and challenges come to materialize they either have a hard time finding ways to resolve the issue at hand or grope in the dark.

Let us delve into some of the frustration-causing miscues that can be seen in the vast majority of shop employees and management people.

Learn CNC Programming

Myth 1: Anybody can run a CNC cutting machine

While a significant number of CNC profile cutters we have today were engineered to allow even an average-skilled person with minimal exposure and training in the manufacturing space run and operate such pieces of machines seamlessly, such applications are infrequent.

Truth is, to become a highly qualified CNC operator, you need to know how to carry out many tasks that require skills and need you to have vast knowledge about them, too.  

Such operator task may include cycle monitoring, cycle activation, work piece measurement, statistical process control reporting, work piece loading and unloading, acceptability evaluation, sizing adjustments, and dull-tool replacements.

The higher your expectations are for an operator, the more they need to know. This explains the reason why it is imperative to give them upskill training programs. Find out here.

Myth 2: A project task that was previously run successfully will still run without any problem or friction in the future

If your setup personnel run into a sticky situation in the job, the manager is likely to say, “I thought we had successfully run this job before”.

The presumption here is that since it was witnessed before the job was successfully run in the past, it would flawlessly run successfully again.

However, it must be noted that the manner in which the job was carried out in the past and the way in which it is executed in the present could run the risk of creating a potential problem. It is important to eradicate variations to make it possible to run jobs consistently without having to run into problems.

Myth 3: G-Code Programming is obsolete

G-Code Programming

Managers are under the impression that when it comes to CNC programming, it can only get done with the use of a company’s dedicated CAM system. It is somehow true. The majority of companies employing CNC technology are also using a CAM system. Or in the absence of which they utilize instead something similar to it in terms of function and usability. 

It is of paramount importance for managers to know that a CAM system’s output is G-code. This is the exact type of G-code which manual programmers write out. It is also the exact G-code program that a CNC machine is capable of executing. 

If in case one of your setup personnel ran across a G-code program that needs changes, it is more convenient to implement required tweaks at the machine level. It is much better that way as opposed to having a  programmer make the required G-code changes under the CAM system. Or restructure the entire G-code program and have the same sent back to the machine. 

When it comes to changing programs at the machine level, it comes to follow that you understand G-code programming to its core.

The Takeaway on CNC Plasma Kits Australia

To become a highly efficient CNC programmer, it is imperative to have an in-depth understanding and knowledge on machine operations, processing, cutting conditions and cutting tools. He also needs to have a good orientation on how setups are made.

It is also expected from a good CNC machine operator to know how to direct operators and setup people. They are the end-users of the program they create.
