Precision machining of thin-walled workpieces post-hardening presents a significant challenge in manufacturing. Traditional workholding technologies often result in roundness deviations of 20 to 30 micrometres, which do not meet the high standards required for many applications. However, a newly developed combination of tools offers a promising solution.
The VL 4 vertical lathe, paired with the innovative PICEA clamping system from STERMAN, introduces a groundbreaking approach to improving machining precision. This system utilises piezo elements that operate at the nanometre scale to meticulously measure the workpiece at six critical points. After calculation, the system determines the ideal centre position and adaptively corrects it – all before machining begins.
In practical batch production, this advancement has achieved impressive roundness values ranging from 5 to 11 micrometres, setting a new standard for precision machining. This is a significant improvement from conventional methods.
The full analysis delves into the core design of this mechatronic clamping system, as well as the integrated measurement and correction processes that drive these results. Such technological strides are crucial in ensuring that manufacturers can meet the stringent requirements demanded by advanced applications.
STERMAN’s innovative solution exemplifies the fusion of mechanical engineering and digital technology, reinforcing their position as a leader in precision manufacturing solutions. These breakthroughs not only enhance product quality but also streamline production processes, offering substantial benefits to the industry.
