CNC machines are sold by many manufacturers at different market prices. These machines are advertised as quality and affordable, with no company claiming the contrary. Quality CNC machines are not cheap and purchasing the right machine may prove to be a challenge. Here is a guide to help you make the right choice.
It is important to go through the manufacturer’s description on the cutting speed before making your decision. High amperage machines have a faster cutting speed than those with low amperage. If you are in a production industry, choose a machine which can handle twice the normal thickness since it allows quick cuts.
2.The thickness of the metal
First, decide on the metal thickness before making your choice. Plasma cutting machines are designed differently to cut materials of different thickness. These machines also have different amperage.
For thick metals, go for machines with low amperage and high amperage for thin materials.
3.Its capability to withstand dust
CNC machines produce a lot of dust and smoke during its operation. Therefore, you should look for a machine that can withstand these conditions. You can also ask the vendor about the machines capability. Make sure you pick the right machine especially when you are dealing with messy operations.
Plasma cutter consumables include the nozzle and the electrode. Manufacturer’s description will include the life time of these consumables. It is best to calculate the cost of these consumable basing on how the plasma cutter will be used. Going for an expensive plasma cutter whose consumables have a longer life span may save your money in the long run.
Portability is also a very crucial factor to consider. If your company requires you to carry the plasma cutter, weight and size must be taken into consideration. Less weight machines are easier to move around, less bulky and comfortable.
This is also very crucial when buying your machine. Some machines provide a nozzle-in place safety sensor. This sensor limits the plasma cutter from operating without a nozzle.
Some Plasma cutters also produce a pre flow sequence which warns the operator when the machine starts arcing.
If you are still not sure of the type of machine to go for, look for a good plasma cutter guide. However, these are some of the things to consider before purchasing a plasma cutter machine.
