Servo Press

Servo press machines are presses forming machines that are driven by electric servo presses to conduct a series of servo based pressing actions. Servo presses are different from hydraulic presses in that the hydraulic cylinder instead of servo motors generates great and sudden compressive forces. The design of hydraulic presses is based on Pascal's principle, that is, the pressure throughout a closed system shall be constant.

Servo presses are not as common as hydraulic presses, which are enlisted as widely used machineries in various industrial sectors, and the model is the machine presses using a hydraulic cylinder that emits great and sudden compressive powers to the relevant objects. Servo forces and servo torques are both stable and powerful force sources for mechanics, so servo presses are highly reliable. 


Hydraulic Mechanism vs. Servo Motions

Not like the servo presses, the composition structure of hydraulic presses is based on the fluid mechanics calculated and given by Frence mathematician Blaise Pascal, in which the fluid pressure throughout one closed force system shall be always constant no matter where it goes, without any exceptional cases.

In a press machine operation, one part of the system is that a piston unit acts as a pump unit, and that piston is designed and developed with moderate mechanical forces acting on a small cross sectional area. Besides this part, the other part of this machine is a piston with a larger area which generates a comparatively relevant large mechanical force. Most of the original hydraulic press machines are designed with the well known C frame structure.

C frame press machines are press machine which are based on the same mechanical principle that is designed with the appearance of a bowed shape that looks like the English letter C, and is usually operated vertically in a perpendicular to the installed ground. As it is perpendicular, the pressing action and the horizontal ground shall be a ninety degree angle to each other. 


Applications of Servo Presses

Now as the technology of both servo motors and hydraulic cylinders are quite well developed, both servo presses and hydraulic presses are commonly used in the metalworking sectors for many kinds of precision forming operations, such as clinching, die pressing, molding, punching, blanking, deep drawing, and still many other metal forming operations onto a wide variety of different alloy materials with complicated chemical and metallic features. The proper way to deal with them may be servo, or may not, depending on the working situation.

However, compared with the hydraulic press machines, the cycle time of the servo presses in regard to the production procedure could be shortened in a significant scale. At the same time, within an acceptable tolerance values regarding the output, servo press machines are able to achieve much high standards that cannot be done easily by ordinary presses due to the servo features. Compared with traditional metal cutting processing that always requires a lot of machining time in cutting and profiling, the procedure of metal press based forming process offers faster shaping process that makes massive production much feasible and is able to be further studied and developed in the phase of speed.


CNC Controlled Servo Presses

CNC servo presses are the popular models in the market now. Even though it is more expensive compared to the older hydraulic presses, the high precision rates and the better controlling experience still move the selling of this type of presses to a new top level in the recent years. They are much more popular in the high end manufacturing site for the production of advanced electronic devices and other stuffs, since they can generate many valuable outcomes for their owners within a adjustable automatic setting.

Moreover, presses are mostly used for mass production model, rendering work pieces in a targeted shape within a short period of time while making a large quantity of items. Currently, the trend of small amount but largely diversified production orders are the leading roles in the world manufacturing industry, so that the issue of a quicker pressing die changes mechanism for achieving agile manufacturing becomes very serious, and the servo motors becomes important in this circumstance.

Since all kinds of manufacturers may use the similar presses model, so that in the global market, it is important and critical for manufacturers across all kinds of industries in the global market to be in touch with the same servo specification with little custom changes and modifications. Business owners in the automotive and electrical sectors are those who adapt to this trend well among many other sectors because with the help of computer assistance such as CNC controller, PLC controller, rather than the manual designs that only benefit the experienced operators but not all the workers, now all the trained junior workers can make precision pressing by setting the numbers unto the control panel and have the actions done by the servo fashions.
