Design engineers are regularly faced with the task of determining the appropriate drive solution for the realization of linear movements. Technological progress is increasing the complexity of systems. Ball screw drives are among the most frequently used drive systems in many areas. Rolled screw drives have established themselves in the linear area and there is no way around cold-formed spindles. The advantages of these drive systems lie in their high efficiency and energy efficiency.
When reliability and customer benefits are no coincidence
Eichenberger's spindle technology, thread rolling (cold forming of the lateral surface of round parts), combines maximum load capacity and force density with enormous dynamics and astonishing precision at maximum running performance. There is enormous potential in industrial automation, robotics and medical technology. However, there are also undreamt-of development opportunities in a wide range of industrial and research applications for semiconductors, photovoltaic systems, vacuum valves, etc. Eichenberger Gewinde AG - incidentally the only manufacturer of rolled ball screws in Switzerland - serves a wide range of industries, from mechanical engineering to medical, electrical and automotive engineering through to aerospace. The various fields of application may be very different, but there are nevertheless many similarities. The constantly increasing quality requirements, the trend towards greater intelligence and the search for cost-effective overall solutions characterize all areas.
What makes the Carry ball screw drive so resilient and the ideal functional element?
Thread rolling produces very precise geometries with a high surface quality. The usual manufacturing processes for threads such as milling, turning or whirling are machining processes. These have the disadvantage that they interrupt the grain flow of the steel. Thread rolling, on the other hand, is a non-cutting process that does not cut the longitudinal fibers, but merely diverts them. At the same time, the surface in the profile hardens. This "smooth surface" offers little opportunity for dirt to accumulate. This is crucial for a long service life and also enables the balls to roll quietly. The cold forming process also results in very good roughness values (~ Rz 1.0) on the thread flanks and in the base radius.
Always in focus: Efficient, economical overall solution for customers
Drive technology finds itself in a field of tension. Increasing time and cost pressures are set against objectives such as precise processes, high load ratings and speeds or long service life. Over the decades, an impressive range of ball and lead screw drives has been developed. Eichenberger's developers always try to build on an existing product and adapt the screw drive to the application-specific requirements. This results in a decisive price advantage and makes the customer's product more competitive.
Together with our customers, we develop screw drive solutions for specific requirements and manufacture them to measure - in the shortest possible time. We challenge the limits of what is technically feasible to give our partners a competitive edge.
