Sliding Headstock on Six Spindles
On my most recent trip to Europe, I visited the headquarters of Tornos in Moutier, Switzerland.
On my most recent trip to Europe, I visited the headquarters of Tornos in Moutier, Switzerland. The timing was good because we were in the process of wrapping up an article for our November issue about the company’s Cyklos surface finishing machine designed to give shops the ability to integrate electrochemical or chemical surface processing into their manufacturing lines. More about this machine can be found in the Tech Brief “Finishing Touch.”
As it turns out, the Cyklos is produced in a different facility than the one we toured. But I did get to see a number of other Tornos machines in various stages of production. The one that most caught my eye this time through was the MultiSwiss, a six-spindle CNC that provides sliding headstock capability on all six spindles. This machine was first introduced at last year’s EMO and was also displayed at IMTS in September.
Designed for parts less than 14-mm diameter (40-mm length), it features 14 linear axes, seven C axes and room for as many as 18 tools (three per position). Quick-change flexibility, wide-open access to the machining area, and the use of standard tooling contribute to its productivity advantages.
The machine is the result of 4 years of research and development in an effort to bridge the gap between single-spindle and multi-spindle lathes. More details can be found in the article “A Multi-Spindle and Swiss Combination.”
Hard turning isn’t hard to do. However, it does require an understanding of the process dynamics and a systematic approach to the tooling involved. This article looks at how proper preparation will deliver consistent, predictable hard-turning results.
Subspindles can do much more than backworking. This article looks a various options currently available.
CNC Swiss-Type machines have more capability built in than ever before. Many of these capabilites can be accessed using attachments that increase the throughput of the machine tool, improve the quality of the work coming off the machine and reduce or eliminate the need for secondary operations even for very complex workpieces.
