Clamping System for Swiss-type Lathes Enables Fast Tool Changeovers

GWS tooling system (linear unit)

Göltenbodt’s clamping system for Swiss-type automatic lathes reduces setup times to increase productivity. Due to the design of Swiss-type automatic lathes, the space for tool changes and setups is often tight. This meant that shank tools had to be completely removed when replacing the cutting tool, resulting in longer setup times.

The design of the Göltenbodt tooling system is adapted to the respective machine type so that it matches the existing interface present on the machine. The existing coordinates —such as the distance to the guide bushing, center height and the distances between the cutting tools — are adapted 1:1.

The shank holder is clamped in the Göltenbodt quick-change holder, removed from the machine during setup and tool changeover, and then measured outside the machine.

Measuring outside the machine reduces nonproductive times, and ensures fast and smooth production processes using spare tools. The company says this process reduces tool changeover times to less than one minute.

The Göltenbodt quick-change holder is clamped and released using a clamping claw with a changeover accuracy of < 0.01mm. An additional locking mechanism secures the holder, further preventing it from falling out.

The integrated coolant supply provides coolant at up to 120 bar directly to each individual tool through the linear unit. The separate coolant manifold enables custom coolant supplies tailored to the requirements or application of the customer. According to the company, the targeted coolant supply thus ensures trouble-free production, improved part quality machining demanding, long-chipping materials, and prolonged tool life.
