Higher precision at increasing speeds. Better machining performance. Flexible production of complex component geometries – from small to large batch sizes. Demands related to international competition continue to grow. Spieth is the right partner for tool machine development and construction.
New-generation machines need to be designed to be highly precise, modular, and in line with customer needs. With the introduction of Industry 4.0, smart factories, and digitization, innovative production technologies and automation concepts are in demand and can generate significant improvements in performance, user-friendliness and ease of maintenance.
High-speed machining processes and high-strength, modern materials place extremely high demands for quality on main spindle drives and positioning drives. High speeds and dynamic accelerations demand excellent axial run-out and positioning precision. For reliable production with minimal tolerances. Economical high-speed precision production is only possible with high-quality connecting elements.

Spieth locking principle of the locknut with an elastic membrane system allows precise setting of pretensioning forces. 360° locking at the shaft assures that forces will be kept during operation of the ballscrew. The 8µm runout accuracy of the clamping set assures minimized vibrations of the system which will result in a precise positioning of the ballscrew and a long lifetime of the connecting components.
Precision, smooth running, long service life and easy maintenance are key features of a high-quality tool spindle. To fulfill the increasing requirements placed on modern working spindles, standard components that are freely available on the market are often insufficient for developing and producing spindles. Because of this, Spieth has collaborated with a major spindle manufacturer to develop a specialized adjusting nut for bearing retention specifically designed around these framework conditions. This specialized nut, optimized to save space, stands out for a high retention value thanks to its design and especially easy installation and removal, while allowing customers to eliminate additional peripheral components thanks to its adapted geometry. This made it possible to not only reduce installation times and optimize service processes, but also to increase the precision of the spindles by reducing the number of components.

Hydraulically activated clamping elements are often very expensive, with complex assemblies and difficult installation. At the same time, these systems offer little radial rigidity. Because of this, a leading manufacturer of 5-axis travelling column machines chose an innovative solution: Spieth engineers worked closely with the customer to develop a hydraulic clamping element based on trusted Spieth clamping set technology that allows for automatic clamping and releasing of rotary tables with a reduced number of components, better radial rigidity and maximum precision. This inexpensive solution stands out with easy assembly and disassembly and high reliability. In addition, thanks to a specialized coating we also achieved outstanding gliding properties. The system has been in use successfully for many years, and represents an alternative to complex hydraulic systems.
