Select CNC Cutting Machine

Selecting the CNC Cutting Machine
Usually, the selection of a particular CNC cutting machine mostly depends on the nature of the cutting job that needs to be performed. The operator of the machine should know which machine is more appropriate for certain tasks.


Based on the operations, the machines are divided into two types:

CNC Cutting Machine

- Straight Cutting: In some cases, the operator should choose the straight cutting machines, as they are the best ones which can perform different operations that require multiple straight cuts.

- Bevel Cutting: For other operations, the operator needs to choose the CNC cutting machine that is able to perform a perfect bevel cutting. This type of cutting allows various functions such as paring, shaving, reducing and trimming the material.

Both cutting types involve the same amount of tear and wear in any CNC cutting machine. This way, there is no significant reason other than the type of operation, to choose a specific machine instead of the other one. However, the manufacturer needs to make sure that the CNC cutting machine comes along with the adequate customer support.

This way, in case that the worker encounters various issues while using the machine, these can be solved as soon as possible. Additionally, the support offered by the CNC cutting machine’s producer should also include spare parts availability. The lack of availability actually means that the CNC cutting machine undergoes a retrofitting.

The Importance of Retrofitting for Producers
The retrofitting is very important for any operator of the CNC machine. And it is important mostly because it actually deprives the producer of important production time. The retrofitting actually reflects on the quantity of goods which are considerably diminished. Due to this issue, the producer is not able to produce the quantities he needs and this thing leads to important losses.

This is why the spare parts for any CNC cutting machine type should be always available. This way, the producer is able to ensure the continuity of its production and complete the orders on time. And for this reason, prior to investing in such a machine, you have to make sure that the manufacturer is able to ensure a constant support and service.

CNC Cutting Machine

We all know how important the quality of services and products is today. It is true that sometimes we are not able to measure the quality of services but when it comes down to products, we can definitely distinct their quality levels. The high quality products are definitely provided by the best materials and equipments. In order to obtain the best products, the industries that are performing different processing tasks in metal, wood and other materials have to use the best CNC cutting machine types. These tools are divided in three main categories: the plasma, water and laser CNC machines.

CNC Cutting Machine

The Functions of a Basic CNC Cutting Machine

Any basic CNC cutting machine should be able to perform oxyfuel and plasma cutting operations. The refinements that are ensured by the basic machines provide the following functions:

- Routing wooden or metal shapes

- Cutting shapes in the end and sides of tubing

- Drilling different soft and hard metals

- Spotting holes for drilling

Any modifications of a CNC cutting machine’s functions should be directed at the installation of the equipment and not during operations, especially if we refer to water or laser jet-cutting machines.

CNC Plasma Cutting Machine

A plasma cutting machine is a machine that uses a plasma gun to cut metals. A CNC plasma cutting machine is a plasma cutting machine that is controlled using a computer. Computer software like CAD and CAM form an integral part in controlling a CNC cutting machine. Since these machines are controlled by a computer, there is a lesser risk of injuries happening to the person controlling the machine. It is an efficient replacement to traditional welding and manual machines. It provides better productivity, less risks and a higher quality of finished products. That is why a CNC plasma cutting machine is preferred to other manual machines.

CNC Plasma Cutting Machine

Let’s first see how a traditional plasma cutting machine works and then how it is integrated with a computer to produce a CNC plasma cutting machine. Traditional plasma cutting is done by passing highly compressed inert gas through a tube. In the path where the gas passes through, an ultra high voltage electric arc is produced so that the gas which passes through is ionized, turning the gas particles to plasma. The temperature of the plasma is sufficient enough so that the metal is cut. The movement of plasma torch along the direction in which the cut is made is quick enough so that the pieces are separated from each other.



The difference between the traditional method and the computer controlled method is that the traditional machine requires the plasma torch to be in contact with the metal which may not be suitable in some cases. The CNC plasma cutting machine controls the movement of the plasma torch. Also, the plasma torch can be directed to cut the metal along different axes to produce parts of varied shapes and patterns. This is where a CNC cutting machine scores tremendously over its manual counterpart.

Choosing a CNC plasma cutting machine out of the various products available in the market can be quite a task. Below are some the factors to be considered while choosing it.

Stable Base:
It is essential that the CNC plasma cutting machine has a solid base to support the entire weight of the machine. Also, it is essential that the base doesn’t move during the cutting operation. If it moves, the finished product will turn out horrible. So, choosing a high quality machine with a sturdy physical base ensures high quality in the finished products.

Electrical System:
The conversion of inert gas into plasma takes place at very high temperatures of 25000 degrees celsius. So, the electric equipment producing such high voltages should be extremely reliable. Any slight increase from the expected voltage might result in an electrical avalanche that can cause serious electrical mishaps and can be fatal to human life.

Accuracy of Plasma Torch:
The rack and pinion mechanism that controls the plasma torch of the CNC plasma cutting machine should work at high speeds with great levels of accuracy. This ensures that the plasma torch operates at the highest level of accuracy producing high quality finished products.

Software Used:
The software application used in the CNC plasma cutting machine should be highly robust and intellectual to maintain greater cut accuracy in the plasma torch. The interface for controlling the software should be user-friendly.

These are the major points to consider while choosing a CNC plasma cutting machine. The machine and the application software should also be expandable to serve future demands. Ultimately, spending a few more bucks in buying a CNC plasma cutting machine should be result in quality finished material and improved productivity.

Used Plasma Cutters

A plasma cutter is a tool used for cutting steel and other heavy metals that are good conductors of electricity. Although metals are durable and strong, they can be easily cut by plasma cutters. In order to build megastructures like skyscrapers and suspension bridges, manipulation of metals is often required. Plasma cutters accurately cut and manipulate the metals as needed. These cutters make use of a plasma torch to cut metals. Plasma is basically a superheated substance that has to be generated through electricity and inert gases.

Plasma cutter

Used plasma cutters are a better option for people who are on a tight budget. You will find plenty of sites online, selling used plasma cutters. Before purchasing any used plasma cutter, it is necessary to confirm that it is in a good working condition. You must also ensure that the cutter is simple to use. Do not compromise on quality or performance to save a few dollars. Buying a low quality plasma cutter is indeed a waste of money. The power requirements of the plasma cutter should also match the power source at your work location. Many a times, people buy this tool at an auction with power needs that are not met at the work location. Most importantly, you need to determine whether the tool satisfies your needs.

Used Plasma Cutters
Most light and large plasma cutters operate on 110 or 220 volts. They normally run with generators and provide an output of at least 8000 W. Many of the used plasma cutters have the ability to handle power fluctuations. So voltage fluctuations that vary from 20 and 30 V won't affect the performance of the tool. Cutting capacity is another major issue of used plasma cutters. If the tool is not able to cut thick metal sheets, then the cutting performance is considered to be significantly low. So when you consider buying a used plasma cutter, determine the thickness of the metal that it will cut easily. Quality and precise cuts are a must for the work to be done. Also determine, if the cutting speed is a factor at your work place. In construction and industrial environments, plasma cutters are used extensively. In such circumstances, higher capacity cutters are a better option as they provide a quicker cutting capacity.

The duty cycle of the used plasma cutter is also an important aspect that should not be overlooked. The term 'duty cycle' gives an idea about how long the equipment will continuously run before it gets overheated. The internal components of the used plasma cutters should also be given due consideration before buying. In case they are not in proper condition, then probably the owner has not taken good care of the tool.

Cables of a used plasma cutter is another factor that needs to be considered. Check whether the cables are cracked or damaged. Worn out cable insulation is likely to cause a malfunction. Therefore it is essential to verify the condition of the cables. Exposed cables may put you in a hazardous situation. Also find out what consumables (used components of the product), that you will get along with the cutter, at no extra cost. You should also assess the cutter controls and confirm that they are working efficiently

CNC Cutting

Sometimes, metal cutting implies difficult operations which mostly depend on metal categories. One method that is the most versatile one is the CNC cutting. This method implies the use of a router, plasma or lathe cutter. When using a particular CNC machine, you have to consider the job requirements. As an example, you can use the lathe cutter to cut soft metals such as brass is but you cannot use this cutter to process strong metals like steel. For this reason, when performing a CNC cutting you have to make sure that the metals hardness meet the machines specifications.

Using the CNC Cutting Machines
The following paragraphs are going to describe different CNC machine types. By discovering this information, you are going to fully benefit from the correct use of the CNC cutting machines.

- CNC Plasma Machine: The CNC plasma-cutting machine is a device which uses heat in order to cut different metals. This machine offers a precise CNC cutting so that it is great in any projects which require high precision. Even more, it is ideal in large projects as its repetitive function can produce many cuts in a short period. These CNC cutting machines are also accessible as both portable and stationary devices.

- CNC Water Machine: This machine functions with the help of a water jet which is directed by a very high pressure. Similar to plasma cutters, the water machines can easily perform detailed CNC cutting operations. The machines offer great cutting methods which produce few residues. Additionally, you can use them in production for repetitive cuts. As well, the CNC water machine provides a smooth, clean edge which always respects project specifications.

- CNC Laser Machine: The laser machines offer an innovative form of CNC cutting. They are ideal for any projects which need “shaker” parts between metal pieces. These parts are small pieces of metals which connect different metal parts in order to form a whole piece. However, the machine performs the cutting as per specification and once the operation is completed, a worker has to remove the unnecessary parts of metal which are held by the metal shakers. The laser machine performs the CNC cutting by using oxygen and nitrogen and always delivers exceptional results with smooth finishing. The laser machine can guarantee the cost efficiency and extreme accuracy for each project.
