Index’s next generation MS32-6 six-spindle automatic lathe brings the benefits of multi-spindle technology to a broader range of applications thanks to a flexible tool-slide platform that reduces changeover times. Accommodating up to 32-mm bar stock, the lathe’s 12 cross-slides enable it to handle a wide variety of complex parts. Two V-shaped cross-slides are equipped with X- and Z-axes located at each spindle position. Users can implement C- and Y-axes and live tools to allow for a broad range of machining processes, including off-center drilling, threading, contouring, hobbing and polygonal turning. All of the machine’s slides can also be alternatively configured for grooving or drilling.
Each cross-slide incorporates Index’s patented W-serration locating system that is said to provide micrometer-accurate alignment of the tool holder. Coupled with the company’s quick-clamping device, users can set up tools off of the machine and quickly install them, reducing tool change times by as much as 50%. Additionally, the machine incorporates the same W-serration system on its live units for drilling, milling and polygonal turning. By presetting tooling for these operations off of the machine, users can reduce setup times by as much as 92%.
Users can also apply twin turrets with rigid tools in as many as five spindle positions. These hydraulically controlled units can alternate between tools in less than half a second. This enables customers to efficiently use separate tools for roughing and finishing in the same position. The twin turrets can also reduce tool changes by incorporating duplicate tools, an option that is especially suited for working with difficult-to-machine materials.
Robotic automation is transforming a job that was perhaps a machine operator’s least-favorite work assignment into one that is not a heavy lift.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
The additional rotary milling axis on these machines allows them to complete many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, eases the programming challenge significantly.
