5 Tips for Choosing a CNC Plasma Cutter
Looking for a plasma cutter? You likely have a lot of questions. Before you start your search, do some research to ensure you choose the right one for your shop. Here are a few factors to consider.
#1: Plate & Sheet Size
Determine the maximum plate size you’ll need to cut, whether it’s 4’ x 8’, 8’ x 10’, 10’ x 40’, or sheets. For sheets, identify how many sheets you need to cover. Every machine model can handle a range of different plate sizes; however, if the size you need to cut is outside of that range, you’ll need to transition to a larger model. Maximum plate thickness is also used to determine which machine model you’ll need, because some models are limited by the size of plasma they can carry, or the maximum thickness they can clear.
#2: Working Areas
The simplest CNC plasma machine only has one working area. This means the cutting table is only big enough for one plate at a time, which is fine for small shops or low-production environments. However, if you want to increase efficiency to load and unload while the machine is cutting, consider a table with multiple working areas, or multiple separate tables.
#3: Process Tools
Do you only require one plasma station or two? Do you want an oxy-fuel torch or perhaps four or eight of them? Keep in mind, the more tools, the wider the machine gets. For instance, think about a machine with one plasma torch and four oxy-fuel torches. To cut a 10’ wide plate, the plasma torch and at least one of the four oxy-fuel torches must be able to cross-cut the entire 10’ wide plate.
#4: Software
Don’t underestimate the importance of programming and nesting software. Even for a small shop, you still have to generate program code for the CNC to run. The good news? Many new CNCs today have built-in programming capabilities, like shape libraries or manual program editors. Many also have the ability to take in a DXF file or DWG file and “post-process” it into M- and G-Code for the CNC to run. But the best results are usually obtained by programming & nesting using special software.
#5: Options
There are countless options to consider when investing in a new CNC plasma cutter. These include the plasma system, duty cycle, oxy-fuel stations, gantry, productivity software, automated tables, dust collectors, and more. The best step you can take is to educate yourself ahead of time. This will help you make informed choices that are most profitable for your business.
