Eichenberger Ballscrews cold rolled excellence!


Design engineers regularly have to determine the most suitable drive solution for implementing linear movements. Today's forever advancing technological progress in machine building and automation has resulted in increased complexity.  Ballscrews and leadscrews are among the most frequently used drive systems in many areas. Rolled thread screws have become established in the linear sector as cold-formed spindles result in highly efficient drive systems with the additional clear advantage of excellent energy efficiency

Reliability and customer benefit are no coincidence

The Eichenberger spindle technology and thread rolling (cold forming of outer surface of round parts) combine maximum load-bearing capacity and force density with incredible dynamics, amazing precision and maximum running performance.

Despite the big differences between the various fields of application, Eichenberger Ballscrews and Leadscrews can be found in the following industries

Industrial automation
Electrical and automotive engineering
Robotic engineering
Medical technology
Satellite technology
Space exploration
Semiconductors research
Photovoltaic systems
Vacuum valves

The similarity in requirement here are high precision, higher intelligence, superior performance  and the search for economical overall solutions.


What makes the Eichenberger cold rolled screws such a resilient and ideal functional element?

Thread rolling produces very precise geometries with high surface quality. Typical thread manufacturing processes such as milling, turning or whirling involve machine cutting the material, with the disadvantage of interrupting the grain of the steel. However, thread rolling diverts the longitudinal fibres rather than using cutting and the surface profile hardens at the same time. This "smooth rolled surface" offers little opportunity for dirt to attack. This is crucial for a long service life and also decisive for the quiet rolling of the balls. Cold forming also results in very good roughness values (~ Rz 1.0) on the thread flanks and in the base radius.

 A radial dynamic force is exerted 
between two rotating rolling dies to form the thread.

Always in focus: Efficient, coste ffective overall solution for customers

Choosing the correct drive technology has many variables to consider. Time and cost pressures combined with  objectives such as precise processes, high load capacities and speeds together with service life. Over the decades, Eichenberger has produced and developed an  impressive selection of ball and leadscrew drives. Designers at Eichenberger always try to build on an existing product and adapt the screw drive to the specific applications requirements. This results in a decisive price advantage, making the product more competitive for the customer.

Moore International can supply you with off-the-shelf or in-house custom machined ballscrews  and leadscrews made to your requirements. By chosing Eichenberger you can be sure of precision from start to finish.
