Small CNC lathes and large CNC lathes compared to what advantage
The workpiece to do rotary motion (spindle, the main movement), the tool to do plane movement (auxiliary movement) of the processing form, known as turning, also known as peeling. This machine is called lathe.
The price is different, mainly because "small CNC machine tools" and "large CNC machine tools" scale is not the same. As the scale is not the same, the machine used by the material, manufacturing equipment, technology is not the same, supporting the control, the implementing agencies are not the same, for example, small CNC machine tools, often as long as eight single board machine with stepper motor can be very good Already working. Large CNC machine tools may be 32-bit (or even 64-bit) host plus servo motor to work properly. Because the scale is large, the amount of data to be processed becomes a geometric progression.
Must say that an advantage is that the price of small CNC lathe will be much cheaper.
Small CNC lathes and large CNC lathes are basically not comparable. Although called "CNC lathe", but their respective areas of work and objects are completely different.
