Retrofits on large boring mills are one of the specialties of the Starrag Large Parts Machining Systems business unit. Sometimes a comprehensive technical cure is required, from complete replacement of the drive units to installation of new control technology. But, if the substance is right, the targeted overhaul of a single central component is often enough to significantly increase a machine’s performance and efficiency.

The headstock of an old Scharmann Heavycut boring mill was mechanically overhauled. This component plays an important role in everyday work, as the heart of the boring mill carries the main spindle, transmits torque and speed to the tool, and ensures smooth running and precise machining, even for workpieces weighing several tonnes, such as turbine housings, ship components or wind power components.

The results of the overhaul are impressive: For the customer, it means working at a new machine level with higher availability, less downtime, improved precision, and repeat accuracy. This leads to greater planning security, as the machine is reliably back in operation. The customer saves 50 to 60% on costs compared to a new purchase with a significantly shorter throughput time.
