Many cutting machines are equipped with a reducer when they are configured, but portable CNC cutting machines are not used. Why is this? The editor of Chengdu CNC cutting machine manufacturer Xiaobian tells you the answer:
The portable CNC cutting machine is driven by a stepper motor, because the stepper motor has a characteristic: the torque is large when running at low and medium speeds. Due to the small size and light weight of the portable CNC cutting machine, the load of the motor is small when it is running. When the torque of the stepping motor is sufficient, the speed can just meet the requirements of CNC cutting. In addition, the internal space of the portable CNC cutting machine is limited, so the portable CNC cutting machine is not equipped with a reducer.
Before explaining whether it needs to be equipped, we need to understand the working principle of the reducer. The reducer is to reduce the higher motor speed and convert it into larger torque. To achieve the perfect balance of speed and power.
In the CNC cutting machine drive system, considering the equipment's own weight and cutting accuracy requirements, it is generally equipped with a reducer. This is widely used in large-scale equipment such as gantry CNC cutting machines, intersecting wire cutting machines, etc. The portable CNC cutting machine is not equipped with a reducer, so I will explain why the portable CNC cutting machine is not equipped with a reducer.
