Plasmacam: What to Know before Buying Your Own Cutting System?

More shops today are realizing the importance of having a plasmacam in their shops. Also, a computer-controlled robotic arm serves as a guide to the plasma torch over the work surface in order to create a complex and intricate cutting pattern. However, it can be challenging to buy a good quality CNC machine. There are a few questions and things that you need to consider that will help make the buying decision a lot easier. Careful research can help you and your company save time and money.

Quality of the Machine


This is the very first thing to consider. You need to be certain that you are getting a high-quality machine. The machine can be a bit expensive, so you need to do your homework and be sure that you are getting the best quality with your budget.




Make sure that you check the quality of materials that are used in the construction of the frame. For example, is it aluminum or steel, or something else? Compared to aluminum, steel is stronger, thus steel machines are lighter and need less material but may have the presence of flimsiness. On the other hand, aluminum is bulkier but possess the appearance of strength.




The quality of the table design should also be checked. There are several factors that can have an impact on the performance of the table and eve the slightest variation can change the performance. For instance, if the gantry is very heavy, it can make the torch to be difficult to control with accuracy and high speed. On the other hand, a lightweight one could produce great results at high speed.




What kind of motor controls the torch? A servo motor is one of the most widely recognized type. It can move to different positions as long as it is within its own range of motion. At the same time, it provides feedback to the controller, informing the controller where it should be at a given time. A stepper motor has a fixed number of positions that it can move to and has no feedback to the controller. This is the reason why there are times that the controller would tell the stepper motor to move to a specific number of steps, but there is no way for the controller to know if the requested movement really occurred.




The software that is runs and designs the equipment is the most significant component of the plasmacam and the table setup. The software is expected to perform two different functions. One is to design the piece that needs to be cut and another one is to control the plasma cutter and table. Although a software such as AutoCAD is best for creating high-quality designs for various applications, be careful as you are not making use of a sledgehammer to swat flies.




A downdraft is a made up of skirts around the base of the table that encloses the entire area under the table and a fan that will suck the air down through the outdoors and table. This is a simple, yet effective system to eliminate dust and smoke. But in every installation, it needs to be custom figured. When you compare tables, make sure that you ask about the downdraft system.

By knowing all these things, you can rest assured that you will find a good cutting system that will deliver the expected results without exceeding the budget.
