More than a few buyers stumble into a competitive market looking for a CNC machine for sale only to find themselves confused, disillusioned and ultimately disappointed. This is mainly due to the fact that their search is random and unfocused without much knowledge or thought of exactly what their application really needs. The result is they end up researching or buying very cheap (expensive) machines that do not give them value or the tools they need to get their projects done. Key considerations have to be analyzed in order to make a sound and profitable investment when looking for a CNC machine for sale. The following questions will help one choose the most suitable machine.
Whats the point of a CNC machine?
Before searching for a CNC machine for sale, take a little time to really evaluate the reasons for buying one. This will help you select the best machine. It is important to establish whether one is replacing existing equipment, adding the capacity of the existing one or upgrading the current ones available. Whatever the reason, it is important to keep the objective clear. For example, purchasing excess CNC Lathes when one requires CNC mills will make one end up with fewer machines that they require and overpay for those they will not use. Moving into new markets also warrants an extensive research on the machines to buy and their prices.
2. What kinds of materials are being machined?
The materials you process will more than likely help you to determine the size machine you need. Easier-material to machine like wood or aluminum sheets under 4×8′ does not require a huge complex piece machinery. Since they an easier to machine, a light-duty piece of equipment is suitable. However, harder materials such as titanium and stainless steel will require more stable and heavy-construction machinery. The machines must have a powerful spindle drive to maintain high spindle speeds and feed rates. A CNC machine today offers a wide variety to choose form depending on the parts being created. The CNC plasma miller is a good choice to operate light material with. For tougher machinery the CNC Laser is appropriate due to its stable high-powered spindle speeds.
3. What tolerances do your projects require?
When producing close-tolerance parts, a very stable and rigid machine is required. The machine should incorporate a powerful structure and design to produce parts at a high speed but while maintaining the accuracy of the parts. Temperature variations are bound to occur when production is ongoing. It is important to look for a device that will monitor the temperature to either allow increase or decrease of the machine speed. CNC routers are very good when considering this factor.
4. How much material does one need to produce?
The materials and production speeds will determine the type of CNC machine to be purchased. When looking for a CNC machine for sale today, the production rates of parts dictate the machine to be bought. For materials such as cast iron the machines chosen should have an adequate horsepower, torque and heavy duty construction. Machines such as the CNC Turret Punch are a wise choice for this job.
5. How complex are the parts to be produce?
There are more sophisticated multi-faced parts such as turbine blades, impellers and airframes that require a greater number of operations. These parts can be produced by using multiple CNC machines but it is always better to use a multi-purpose machine. The most common machines that facilitate the functioning of more than one CNC machine in a single one are the vertical machining centre (VMC). They are capable of up to a 5-axis machining functionality. The multi-purpose lathe is another good functionality combined machine. The advantage these machines offer is that they require fewer costly fixtures and specialized tools, reduce operator time per part, and increase spindle usage and provide flexibility of parts.
6. Are the parts being produced associated with each other?
A CNC machine comes with more interactive controls that help in reducing setup times, manage production schedules and monitor material usage. All a person does it to set the parameters for the associated parts and the machine writes a program to facilitate the production of all of them. All this will lead to better productivity and profitability. The best machines come with a swivel Head Rotary Table and a Travelling column. The VMC machines are the ideal ones to buy when looking for these features.
With the right answers to these questions, one will be in a better position to purchase better machines when looking for a CNC machine for sale. It is important to ensure that the investments people make are worth it to ensure long-term profitable investments.

Below are a couple links I found helpful with this Epilog laser review. I’ve found them and Universal a little over kill on price due to the extra features and CNC milled parts all done in the USA. Feel free to leave your comments.
Hurricane Laser reviews will show mixed opinions. Most forums show recent activity.
CNC stands for ‘Computer Numerical Control’. That means computer has the ability to change the design patterns into numbers, produced by Computer Aided Design Software (CAD). These converted numbers control the movement of the cutter. In this way, computer controls the cutting and engraving of the objects.
A CNC Laser Cutter allows for extremely precise cutting and engraving of many materials such as wood, foam, concrete, different metals and many others. It contains a sharp and pointed router to produce clean and exact cutting of the material. This sharp cutter can even cut most organic materials and depending on the power metals as well.
This process of cutting is controlled by the computer system in which the required software and hardware are installed. In big industries, a high powered laser cutter is often used to cut sheet and piping materials. Different companies use this technique to increase their outcome. Because less men power is required for this technique and it consumes less time to laser the material in efficient way than the older process to cut the objects. You can attach this machine with your desktop to make designs and images.
High laser beam is required to obtain a clear and clean material. But the amount of laser cutting power is depending on the thickness of the material. It is the most easy and efficient way to laser or cut the materials.
The use of modern Technology has increased in last few decades. These technologies have made everything easy. CNC Laser Cutter allows you to make different patterns and designs on different materials. Some parts of jeweler are also designed and cut by using this technique. There are several methods that are used in cutting using lasers and such methods may include vaporization, melt and blow, melt blow and burn, thermal stress cracking, scribing, cold cutting and burning stabilized laser cutting.
This machine is easy in use and to handle. But a lot of concentration is required to control this machine. It is a safe mode of working especially in industries.
In CNC laser cutter mirrors and lenses are also installed and aligned. After which you can also design create different colors across all types of materials. Pulsed lasers is also a great factor that is very effective in Laser cutting processes specially piercing, or when very small amount of cutting speed is required. The technology of laser cutter is more precise and consumes less energy for cutting metal sheets than plasma cutting. But the maintenance of the machine is very necessary. It should handle with great care. By using CNC laser cutter we are able to design different wooden frames and there are unlimited opportunities for us to deal with this new technology in a useful manner. It increases the productivity of any company. In less time, it gives more outcomes with a small amount of men power. CNC Laser Cutter is very affordable and useful as well. This machine has a high processing speed. You can cut and engrave the material with the same machine. It has made human life easy. The worker has no direct contact with the machine tools; the machine can be controlled through operating system and by pushing just a single button.
