Milling machines are complicated and advanced machines, used for the most demanding operations. As you would imagine, they are rich in features, and they are complicated to use. But first of all, it is complicated to choose the best one, simply because there are a lot of different models on the market.

You will have an opportunity to choose between a manual and a CNC milling machine. CNC models are more expensive and they are more professional, while manual are more affordable and they are simpler to use. Addition: Most CNC models are improved and upgraded manual models. Now we have come to the size. In this case, a bigger milling machine is better. The main advantage is in the construction itself. Larger machines are made from steel and they are more durable and rigid. All of this guarantees you that you can use them for rougher and more precise operations. At the same time, we will add that the best milling machines must withstand all types of use, such as shaping steel for example. A power for a milling machine is mandatory. Models with 1 HP electric engines are usually the best choice. The main goal is to have a lot of torque and available speed (you won’t always use the top speed). This is needed for different types of metal. Steel requires a high level of torque and low speed, while the aluminium must be processed with a high speed and low torque. A related feature is the phase of electric motors. Those with 3 phases (gears) are the best choice! You can choose the speed and therefore the torque, accordingly to your need.
