Precision spindles from Bachofen: perfect finish for complex workpieces
The initial situation
Cylindrical grinding machines from the traditional Swiss company Fritz Studer AG operate at full capacity in industrial manufacturing facilities around the globe. Their hallmark is the highest level of precision, which all moving machine components must meet without compromise – especially the screw drives used in the CNC universal external cylindrical grinding machines of the S31, S33 and favorit models.
Project requirements
- Significant support for a flawless visual grinding finish
- Maximum precision, positioning accuracy and absolute rigidity of the screw drive component
- Complete fulfilment of the strict technical requirements of Fritz Studer AG in terms of quality and function
- Technical support and assistance during the testing phase
- Good value for money
- Reliable delivery and adherence to deadlines
Bachofen’s solution
With the THK ball screw drives, Bachofen is able to propose a solution that is well received by the design engineers at Fritz Studer AG. The positive first impression is confirmed in tests with several spindles: the THK precision components perform the movements on both the longitudinal and transverse axes with the required accuracy. Thanks to their smooth-running characteristics, they ensure a perfect visual finish of the ground surfaces. Bachofen wins the contract and supplies the spindles for the cylindrical grinding machines in a total of five different lengths. Fritz Studer AG is not only convinced by the product – it also values the technical advice provided by Bachofen’s motion technology experts and the reliable delivery of the components. That’s what makes partnership-based collaboration enjoyable.
