New and Different—Really

“New” and “different” are often overused terms, but a new multi-spindle machine introduced by Tornos at this year’s IMTS (Booth S-8666) does fit the description. The Multi-Swiss is a six-spindle multi machine with the additional wrinkle of providing sliding headstock capability on all six spindles.

“New” and “different” are often overused terms, but a new multi-spindle machine introduced by Tornos at this year’s IMTS (Booth S-8666) does fit the description. The Multi-Swiss is a six-spindle multi machine with the additional wrinkle of providing sliding headstock capability on all six spindles.
 
Like a conventional Swiss-type machine, Z-axis motion is generated by the stroke of the main spindle or, in the case of the Multi-Swiss, all six spindles operating independently. The Z-axis stroke of this 14-mm-diameter machine is 50 mm, with a maximum part length of 40 mm.
 
There are some that might take issue with calling this machine a Swiss-type since it does not use a guide bushing. However, the point is that the machine’s Z-axis motion is generated by the linear motion of the main spindles, eliminating the need for compound slides on the cross-slides.  
 
The machine is fully integrated, including a barfeeder, electronics, chip conveyor and ancillary equipment, all on a single platform. The machine uses 1.5-m bar stock, which reduces the overall footprint by 35 percent and enables higher rotational speeds for the machine’s main spindles.
 
The heart of the machine, or of any multi-spindle, is the spindle drum. Integrated 5.6-kW motors with an active cooing system can provide rotational speeds up to 8,000 rpm for each independently programmable spindle. The machine uses a torque motor for positioning and indexes station-to-station in 0.3 seconds. The drive motors are hard wired, so a reverse rewind is a necessary part of the cycle.
 
If your shop does medium- to high-volume production of highly complex parts, check out this new machine at the Tornos booth. It really is new and different.

While it is important to just walk the show floor to see what new technology is available, make sure you are checking the show for lunches, knowledge bars and other opportunities to learn.
