Manhart What are the most critical technical parameters of a rolling machine?

The most critical factors in the technical parameters of the bending machine include but are not limited to the following:
### 1. Hydraulic cylinder thrust
**Importance: The thrust of the oil cylinder is a key indicator for the material thickness and strength that the bending machine can handle. The greater the thrust, the thicker and stronger the materials that the equipment can handle, thereby meeting a wider range of processing needs.
**Specific parameters: For example, some models of roll bending machines have a hydraulic cylinder thrust of 25T or higher, which is particularly important for processing thick walled materials.
### 2. Repetitive positioning accuracy
**Importance: Repetitive positioning accuracy reflects the consistency of the equipment in multiple processing and is the core indicator for evaluating processing accuracy. High precision repeated positioning can ensure the quality stability and consistency of the processed workpiece.
**Specific parameters: Generally speaking, the repeated positioning accuracy of the bending machine should reach 0.01mm or below to meet the requirements of high-precision machining.
### 3. Roller parameters
**The number and layout of rollers * *: The number and layout of rollers directly affect the shape and accuracy of the processed workpiece. For example, a three roll bending machine has two transmission rollers and one adjustment roller, and the bending radius can be changed by adjusting the position of the adjustment roller.
**Roller diameter and spacing * *: The diameter and spacing of the rollers are also key parameters that determine the size range and shape accuracy of the processed workpiece. The selection of roller diameter should be based on the thickness and bending requirements of the processed material, while the adjustment of roller spacing is used to adapt to the processing needs of different curvatures.
### 4. dynamic system
**Motor power and torque * *: The motor power and torque determine the processing capacity and efficiency of the bending machine. Sufficient power and torque can ensure stable operation of the equipment during the machining process and meet various machining requirements.
**Transmission mode * *: Transmission modes such as mechanical transmission, hydraulic transmission, etc. can also affect the stability and response speed of equipment. Hydraulic transmission systems typically have higher transmission efficiency and better stability, but maintenance and management of hydraulic oil also need to be considered.
### 5. Control system
**CNC control system * *: Advanced CNC control systems can improve the automation level and machining accuracy of rolling machines. CNC systems can accurately control the motion and machining parameters of each axis, achieving precise machining of complex workpieces.
**User interface * *: A user-friendly interface helps simplify the operation process and improve operational efficiency. An intuitive user interface can reduce the training time and the possibility of misoperation for operators.
### 6. Security performance
**Safety protection devices such as protective covers and safety switches are important measures to ensure the safety of operators and equipment. These devices can quickly cut off power or stop equipment operation in emergency situations to prevent accidents from occurring.
**Emergency stop function * *: The emergency stop function is also one of the key safety features. It allows operators to quickly shut down in case of emergency to protect equipment and personnel safety.
In summary, the most critical factors in the technical parameters of the bending machine include cylinder thrust, repeat positioning accuracy, roller parameters, power system, control system, and safety performance. These factors collectively determine the performance of the bending machine in terms of processing capability, processing accuracy, stability, and safety.
