Acquiring a plasmacam system is not a walk in the park or as easy as racing your way down to the nearest hardware store, and picking one up. The money-making possibilities of CNC plasma machines are virtually endless, and we attribute this to its ability to provide high precision cutting output.
A growing number of shop owners around the country have given their affirmation that plasma cutting tables are among the great items they added to their shops recently. The computer-manned robotic arm is used to guide and direct the plasma torch over the material surface being worked on, allowing it to cut through it and create the desired intricate cutting patterns.
Consider answering the following points to help and guide you on how to have easy buying decision-making. This would certainly help save you considerable time and money.
High-quality machine, this should be the first thing that you should be looking for when it comes to plasmacam. Above everything else. CNC plasma cutting tables, regardless of who manufactured them, will always come with a hefty tag price. If you will do your homework beforehand, and that is searching for top-caliber equipment and is priced within your disposable budget — you’d have high chances of getting your money’s worth.
It is a good practice to always check out and verify the quality of materials that are used in constructing the frame of your plasma cutting system. Is it made from aluminum or steel? Or was it made from something else?
Since steel, by their natural quality, comes stronger and more durable than aluminum, steel machines would be requiring less of this material and thus would probably be so much lighter than others. A possible drawback though is that it would give the make the appearance of flimsiness.
As for the aluminum machines, they tend to come bulkier but will look like they have that needed strength and durability. Machines that come from either of the two materials tend to come with more strength and are more durable, and can easily handle even the toughest of jobs.
The cutting table design is not something that you should skimp on, particularly its quality. There are a handful of factors that can affect the table performance, and variation even the slightest kind could somehow alter the cutting table performance. To better illustrate this, here is an example.
Take for instance the gantry (this is the bar that you can slide up and down across the table length). If this comes too heavy, it renders that torch unwieldy and difficult to control with high accuracy and speed. On the other hand, a light-weight type would likely produce astoundingly accurate results, even at super-high speeds.
What kind of motors is likely to control the torch? If you look at Servo motors, you’ll see that they are widely accepted and more sought after when compared to Stepper motors. You can move them to an almost countless number of motions. It also reports back to the controller to give an update where it happens to, right there and then that very moment.
Stepper motors usually come with a limited number of positions that it can move to, but unlike Servo motors, they don’t have any mechanism to give any feedback to the controller. There would be some instances that the controller would let the Stepper motor know that it needs to move itself to a certain number of steps. On the other hand, don’t have any way to determine if the movement request was actually carried out.
Now, this may be the last point to ponder here, but this one holds greater relevance. It is important to check out on the warranty also that comes with the table. Can you ensure that the manufacturing company would be standing behind their product offerings? Needless to say, a longer warranty period is more desirable and more advantageous than having only a short warranty period.
Ask yourself if all parts would be covered under warranty, or it would only include just some parts? What can be expected after the warranty has lapsed for your plasmacam? All these can be addressed by your dealer store and will help you make your decision whether you should proceed with the purchase or whatnot.
