The differences between pipe bending machine automatic and semi-automatic pipe bending machine

As pipe bending machine factory, FYCHIS MACHINERY can offer customers several types of pipe bending machine: pipe bending machine nc, cnc pipe bending machine hydraulic and 3 axis pipe bending machine cnc to meet their different production requirements. The pipe bending machine nc is also called semi-automatic pipe bending bending machine while the cnc pipe bending machine hydraulic and 3 axis pipe bending machine cnc are called pipe bending machine automatic. All these pipe bending machines have the same pipe bending machine function: to bend pipes in certain angles with the help of pipe bending machine die. And the same pipe bending machine can be square pipe bending machine, rectangular pipe bending machine, oval pipe bending machine and pipe bending machine round if use corresponding pipe bending machine die. But, what is the difference between these pipe bending machines? FYCHIS MACHINERY will introduce their differences in detail.

1.The differences in structure

CNC pipe bending machine design: PLC control system, servo motors control feeding, rotation of tubes and bending and hydraulic system work for moving forward and backward of the pipe bending machine die.
NC pipe bending machine design: Single chip microcomputer controlling and hydraulic system control bending process.
Comparing cnc pipe bending machine and nc pipe bending machine design we can find out that the structure of cnc pipe bending machine is more complicated. On a automatic pipe bending machine we can see pipe bending machine mandrel system, pipe bending machine die, drawer slide for feeding system and tube rotation system on the frame of the pipe bending machine automatic. A servo motor is installed under pipe bending machine die.

Structure of NC pipe bending machine round is more simple. On the main frame of the pipe bending machine round the pipe bending machine mandrel system and pipe bending machine die are installed. The hydraulic cylinder under the pipe bending machine die is in charge of the bending work.

2.The differences in the bending efficiency

The operation of a nc pipe bending machine equipment is quite complicated if there are several bends on the same pipe. The operator needs to take out the pipe after one bend and puts the pipe at the proper point for the next bend. Although using positioning device can help the operator to locate the bends, the operation is really very complicated and it takes longer time.

The cnc pipe bending machine is automatic pipe bending machine. The operator only needs to input bending parameters in the pipe bending machine. Servo motors on the machine control the feeding, rotation of tube and bending process. The PLC system of the automatic pipe bending machine send pulses to servo motors, servo motors rotate corresponding distance and send back pulses to the PLC system. Thus, the cnc pipe bending machine for sale can do automatic feeding, automatic rotation and automatic bending with high accuracy. The operator does not need to take out the pipe even there are several bends on the same pipe.

3.Difference in bending precision

The cnc steel pipe bending machine has higher bending precision. As mentioned before, servo motors are in charge of the bending process of the cnc steel pipe bending machine. So the bending can de done quickly and precisely. The tolerance of bending angle of tube bending cnc pipe bending machine is about 0.05°. The tolerance of steel pipe bending machine for sale is about 0.1°. Howerver, using the steel pipe bending machine for sale to do complex bending not only takes time but also has risk of low bending precision. The operator needs to take out the pipe and put it in the right position and correct direccion for the next bending. A little difference in position or in direccion may lead to disqualification of the pipe.

4.Difference in nc steel pipe bending machine cost and cnc pipe bending machine cost

There is a big difference in semi automatic pipe bending machine price and cnc pipe bending machine price because of the dissimilarity in structure and control system. The price of cnc pipe bending machine is much higher than the semi automatic pipe bending machine price even when they have same bending capacity. For example, both the pipe bending machine 38NC-DW and 38CNC-3B can bend tubes less than 38mm x 2 mm, the price of 38NC-DW is 4000 dollars while the price of 38CNC-3B is 14000 dollars. And this dissimilarity in price is more obvious in large diameter pipe bending machine. The price of pipe bending machine 100NC-DW is 20000 dollars and the price of cnc pipe bending machine 100CNC-2B is about 41000 dollars.

5.Difference in pipe bending machine function

The control system of automatic pipe bending machine is PLC system and the display screen is the operation terminal. The PLC system outputs command to position unit and the position unit outputs command to servo motor. Servo motor rotates according to the command and give back position information to PLC. By this way, automatic pipe bending machine can guarantee high bending accuracy.

The cnc pipe bending machine has the automatic error diagnosis function, errors will show on the display screen If encounter trouble during the bending process and operator of pipe bending machine cnc can solve problems quickly.

These abouve are distinct and well known advantages of a cnc copper pipe bending machine. The cnc copper pipe bending machine has more advance funtions that the nc pipe bending machine cannot achieve.

1) Usually, a cnc pipe bending machine for sale has 3 axis: feeding, rotation and bending. And it can be a cnc pipe bending machine 5 axis when it’s necesary. For example, when we need to bend several times on the same pipe and these bends are in 3 bending radius. In this case, a cnc pipe bending machine 5 axis can be very helpful and labour saving. If we use a nc pipe bending machine equipment to do this job, we need to change pipe bending machine die because of different bending radius. And this will cost a lot of time. 2) A tube bending cnc pipe bending machine can install the industrial control system. With this system, the tube bending cnc pipe bending machine can read CAD drawings direcctly and transform the CAD drawing into datas of X,Y,Z axis, and realise the bending work. This function can save works of the operator and improve the work efficiency.
