Now there are many types of aluminum profile cutting machines, and customers have higher and higher functional requirements for cutting machines. Therefore, as a buyer of an aluminum cutting machine, it is very necessary to pay attention to some purchase details of the aluminum cutting machine when purchasing.
The following are the purchase details that should be paid attention to when purchasing an aluminum cutting machine:
When purchasing an aluminum cutting machine, you must pay attention to its cutting capacity, including parameters such as table area, maximum cutting depth and maximum cutting length.
For cutting, it is also necessary to select the corresponding speed according to the model of the aluminum cutting machine. The speed of the saw blade is actually very important.
For some high-precision aluminum cutting machines, the speed matching degree is very high, because it needs to be adjusted according to different profiles. To adjust the speed of different saw blades, this situation requires the aluminium cutting machine to have speed adjustable.
The cutting accuracy of the aluminum cutting machine directly affects the quality of the cut product, so it is necessary to pay attention to the cutting accuracy when purchasing.
First of all, the cutting accuracy of the aluminum profile cutting machine should be high. The high precision is related to many factors. Not only the feeding accuracy must be high, but also the cutting accuracy must be high. The high feeding accuracy must be the motor. Drive feeding also has certain requirements for the rationality of the design of the mechanical structure. Many cutting machine manufacturers often have problems with the size of the feeding material, which does not appear in the use of accessories, generally because the mechanical structure design is unreasonable that leading to feeding not accuracy.
The working environment of the aluminum cutting machine is relatively harsh, so it must have strong durability and be able to maintain stable and reliable performance in long-term use.
The operation process of aluminum cutting machine is relatively dangerous, so it is necessary to pay attention to its safety when purchasing, including whether it has safety protection devices and whether it meets relevant safety standards.
5. Price:
The price of aluminum cutting machine is relatively high, so you need to make a reasonable choice according to your own needs and budget when purchasing. At the same time, be careful not to choose low-priced products blindly, so as to avoid problems during use.
Of course, after buyers of aluminum cutting machines purchase suitable aluminum cutting machines, it is necessary to carry out regular inspections and maintenance work on the aluminum cutting machine which only on this base that can make your aluminium cutting saw machine with high productivity benefits!

Hi - I don’t currently have a CrossFire PRO but I am seriously considering purchasing one for my manufacturing business that will be used exclusively for cutting out aluminum parts. I have some questions that hopefully someone can shed some light on to see if it is the right fit for what I need. right now I outsource my aluminum parts to a local machine shop that cuts them out from 1/8" aluminum using a water jet. I purchase 2,000+ of these parts every year from them. I also purchase around 500 parts from them made from 3/32" aluminum. The part sizing is basically 3.5" X 1.5". I have read several posts on the forum board regarding the difficulty of getting the plasma cutter “tuned” correctly to cut aluminum so the edges are acceptable. Attached is a picture of what is acceptable to me on a couple parts I have sitting around. One of the parts is cut from a water jet and the other part is cut from my own CNC machine using a router with a fluted metal bit. While the water jet is much better, both edge finishes are acceptable to me. After I tune the CrossFire PRO, can I expect similar results as in the picture?

A couple other quick questions:
Obviously I am new to plasma cutting so I apologize for the rookie questions.
As far as I know, the general progression of cut quality (and cost) goes from lowest to highest : plasma -> waterjet -> laser. But you can get some excellent cut quality on plasma, especially if you are doing the same parts over and over and you can really dial in the settings. As far as plasma cutters, Hypertherm is generally regarded at the high end, and for what you’re doing, I’d start there and make sure you’re looking at machines with 100% duty cycle. The HTP Microcut is another highly regarded machine as well. Miller, Lincoln, ESAB, and others make fine machines as well.
Plasma can leave some dross/slag on the cut - if done right, it will fall off easily, but cleanup can add handling costs to the workflow. If you are tumbling the parts after cut, you’ll probably be ok. Laser and waterjet generally don’t have too many issues with this.
If you’re outsourcing the cuts - perhaps can find a shop that does plasma and let them do a batch?
Hope that helps!
Thanks for the input @TomWS! In my research the past few days I did come across a few articles that gave some great information on aluminum plasma cutting. As you pointed out, Hypertherm has a couple of them. One in particular was very informative which can be found at https://www.hypertherm.com/en-US/learn/articles/guide-to-plasma-gas-selection/
I want to make sure I am buying production quality equipment that can cut aluminum with a nice edge for 2,500+ parts per year.
Any other recommendations?
Interesting question. I am totally convinced that the Langmuir product is probably one of the best quality systems you can get for your money, but only IF you’re able to build it and get it working. It’s not hard, but it is not a ‘turnkey’ system. If you want that you’ll have to spend 5 to 6 times more, at best. However, if you have someone who is willing to build it and learn how to tune it, you’ll have a great system in the end. And, once you have that, YOU will be able to maintain it and you won’t be dependent on someone who will want you to ‘upsell’ to the next ‘feechur’.
Good dry air. The HT will have the duty cycle you want from the plasma and great cutting capabilities (some plasmas can only run 30% duty cycle - they need to rest 7 minutes out of 10…that doesn’t mean run for 6 minutes and then rest for 14 out of 20, it’s run for 3 and rest).
But that also requires high air flow (SCFM) and dry air. So add a good compressor with a tank of reasonable capacity (60+gal) so it doesn’t have to cycle on all the time you’re cutting. Then add a dryer (either passive like the copper tubing run approach often posted here or active requiring a powered unit that removes the moisture).
Those 3 things are the most critical. After that it’s just dialing it in and changing consumable before you can drive a truck through the tip (some people will try to stretch their consumables to save $15 and burn up a $100 sheet of metal with crappy cuts as a result). DAMHIK
