A servo transfer, also known as a servo transfer system, is a system that provides automatic control and motion transferring from the motor to the drive in order to allow for the continuous operation, which is usually seen on a servo press.
On a servo press, the servo transfer is often in combination with the servo motor and servo drive on a computerizes controlled servo press, which contains the servo encoder and the servo transformer that provides continuous and accurate movements that drives the moving parts of the press.
In a CNC machine that applies computer to control the parameters including the speed, torque, and moving orientations of the moving parts of the machine, such as the spindle and the tools, a servo transfer system is required, since it is the system that performs these works for the CNC machine.
No matter the manual control machines or the machines that are combined with the CNC system, there are several complex components that require to be carefully operated. Although the experienced operators are definitely capable of handling these operating processes, to improve the accuracy and productivity of the works and enhance the quality of the products, they cannot be achieved without a servo system.
With a servo system, the parameters that determine the performance of the works can be transformed into numerals or the so-called codes, which allows for the machine to follow the standards to operate. In addition, as the CNC machines that adopt the servo system don’t have the limitations that the manual operated machines would have, they can be made of larger sizes that serve for more loads at a time, which results in the high productivity of these machines.
Depending on how the servo transfers are mounted and the space the systems would take up the entire machine, they can be divided into two types, including the through-the-window mounted system and the front-and-back-mounted system.
● Through-the-window system
As the name suggests, the through-the-window system is set up through the both ends of the compatible machine, and is equipped with the transfer-finger bars throughout the system, which take up a large amount of space for the machine.
Since the transfer-finger bars for this type transfer the instructions from the computer through the one end to the other of the machine, the span of these bars must be long. In addition, for the machines that come in larger sizes and adopt this type of servo system, the span of the transfer-finger bars should be even longer, which makes this system be limited in space when it is necessary to be applied.
● Front-to-back system
The front-to-back system, which covers the space of the machine from the front to the back, would take up less space as it transfers the instructions only in the center of the bar, instead of the transfer-finger bars that run through the window of the machine.
This makes the total span, width, or weight of the front-to-back system be saved for a lot amount, as the requirements of the long bars are eliminated, which allows for the smaller and light bars to be set up.
● Compatible with a wide range of loads
Since the servo transfer is often used in a CNC machine that is controlled automatically by the computer, it would not be restricted to the limitations that the manual operators may have, such as the break and off time that are required and the limited physical strength that the operators have.
Therefore, the machines that are in conjunction with the servo transfer can be designed as larger and heavier sizes, which allow the machines to work with more loads at a time. If the required loads are small, this device can also help control the operation properly without problems.
● Improved stability
This is one of the features that make the automatic operation surpasses the manual operation of the machines. When it is necessary to make an adjustment for the machine during operation, or there are some slight external disturbances, the servo transfer can ensure the stability of the machine.
In contrast, the manual operation of the machine would take more time to stabilize the machine, which is less efficient than the former one.
● Definite accuracy
Since almost all functions on a CNC machine that adopts the servo transfer are conducted by following the codes, this device can also ensure the definite accuracy, including the displacement accuracy and the positioning accuracy, etc.
● Fast response
This feature of the servo transfer improves the efficiency and the productivity of the machine that it serves for. Because the components that are driven by the servo system can respond to the instruction fast, it would not take a lot of time to complete a cycle of the work, which allows for the larger scale of production accordingly.
