Servo Press for assembling, press fit, metal forming and testing machine with built-in process monitoring


Auloma propose an extended range of servo presses modules with a built-in process monitoring. Our range of servo press is developed to match and solve whichever exigences and applications. The differences between the various models depends by the power transmission, the ball screw type and the force sensor and you can choose what is the best servo press modules for your project. The power transmission could be actuated directly by a stiffness join coupling or by a timing belt with zero backlash and thanks to the high performance and features of our belt both solution can provide an upper torsional stiffness. Our modules can be equipped with different ball screws and this choice depends by the precision that need the applications. Auloma utilise only ball screw with the nut preloaded to avoid axial backlash and thus means high axial stiffness and low deformations procured by the compressive strength. The precision of the press ram is fundamental in press fit applications. To guarantee a precise positioning Auloma's servo presses mount mainly grind ball screw according ISO IT3 standards and on request ball screw manufactured according the standard ISO IT1. Exist many way to measure a force and this depends mainly by the accuracy that you need. Auloma can provide the two solutions of direct or indirect force measurement. In direct force measurement the force sensor is mounted directly on the press ram in the force path. Auloma suit in its servo presses a tool holder made in according at UNI 441 standards with a force sensor embedded, this solution with strain gauge force sensor own an accuracy of 0.35% on the full scale. In indirect force measurement the strain sensor is embedded on the body press and provide force measure with an accuracy included in a range of 0.3 to 1% of the full scale. .


The main benefit procured by a servo press consist in a solution for automated assembling, metal forming and testing machine that doesn't need of any software development to obtain a process monitoring. Thanks to this solution the development costs results cutting on the roots and the users can invest the budget in others project's items. The importance of a device with a process monitoring integrated will be a constant control of your process in run and all defects and abnormalities will be seeking in real time. This solution give to you the confidence that scrap parts won't be shipped to your customer and many expensive end production test could be eliminated.

Principle of Working

servo press working scheme

The servo press provide in the servo drive interfaces two analogue outputs. Encoder feedback and force sensor measures are analysed by the APM process monitoring software installed in the servo press controller. The controller has dedicated two analogue channel to execute the process analysis. In the channel (x) is possible set the ram position values and in the channel (y) is possible set the Force values. The waveform obtained by interpolation of two channels correspond at a mathematical model of the processed parts. The APM working for comparison and use a recorded masterpiece waveform to compare all processed parts. In APM process monitoring is possible on the masterpiece waveform set-up the off set force limits, this to create the force tolerance limits to discriminate the defected parts through waveform analysis. The APM process monitoring is available in the servo drive PLC built-in or in a stand alone PLC's CPU control unit. The response pass or fail (OK or NOK) of the processed part is noticed to main machine control ( operator console ) by a digital output.
