There are three points in the operation of a press brake that will determine how fast it works: down speed, working speed and return speed. For NC press brake, it will use 6:1 or 8:1 cylinders, and for CNC press brake, it will use 13:1 or 15:1 cylinders, so the CNC press brake works faster than the NC press brake.

One of the features of Onefinity CNC Elite machines is it's advanced close loop stepper motors over the open look stepper motors of the X35 and X50 Onefinity machines. Most hobby CNC routers use open loop steppers. Many new users to CNC machines often wonder the differences between the two. Let's look at the …
The open loop system means the output of the system is free from their input. In the closed-loop system, the desired output depends on their input. The open loop system is called the non-feedback system while the closed loop is the feedback system. The control and controlled process are the two components of the open loop system.
