Arno Werkzeuge's AWL Toolholder Mounts Directly to Star Micronics Lathes

Arno Werkzeuge’s AWL direct-mount toolholder for Star Micronics-brand Swiss-type lathes is compatible with Star Micronics’ SR 20R II, III and IV machines currently. When combined with the AFC quick-change system, users can increase productivity for Swiss-type machines through reducing setup and non-productive times.

Designed for turning or grooving tools, the AWL toolholder has an integrated adjustable high-pressure coolant supply ranging to 130 bar. Two separate cooling channels can be selectively opened or closed. The various connection options make it adaptable to several machine types. Depending on the machine, the new AWL direct mount can fit from two to six tools. Each chamber has an integrated coolant supply to allow the simultaneous use of several tools, whether they have internal cooling or not. Since the direct mount is designed with integrated cooling, it dispenses with the time-consuming connection of external and cost-intensive tubing.

When turned, an integrated counter nut raises the wedge slightly to speed tool removal and fitting. “The direct mount can also hold the tools of other manufacturers. The freedom of tool choice is one of the greatest benefits of our AWL direct mount,” says Werner Meditz, head of technology at Arno.

“Users have the best benefits when they combine the AWL direct-mount with the AFC quick-change system,” says Simon Storf, marketing manager, since to change a tool, only the front part of the two-part holder needs to be removed and a new tool is then fitted with a different holder. This combination dispenses with the need for recalibration in many cases, according to Mr. Storf.
