The main spindles have a higher maximum speed, up from 7,000 to 8,000 rpm, and over 50% more power at 19 kW. The multi-spindle machine can be equipped with six pairs of V-shaped cross slides and X, Y, Z axes at each spindle position, with the option of a simpler single-axis NC grooving or drilling/boring slide to serve any of the six spindles.
Fluid cooling results in high power output, allowing elevated loads and speeds without excessive heat generation. The ability to select speeds and feeds independently at each spindle results in optimal chipping, maximum surface quality, extended tool life and short production times, even when processing exotic materials, says the company.
Each cross slide now has a W serration that matches a similar feature ground into the tool holder, whether for a live or static cutter, facilitating its alignment to micron accuracy and speeding set-up. The operator can pre-set the holder externally, then place it on the slide and fix it in position using a quick clamping device from Index. Only a quick turn with the wrench renders the holder ready to use.
Simultaneous rear end-working capability has been improved, as either one or two swivelling, C-axis synchro-spindles now position themselves in two NC axes on a pair of slide-ways, rather than one, and may be equipped with up to six tools, half of which may be driven. This configuration provides users with a broad range of machining options, including off-centre drilling, threading, contouring, hobbing and polygonal turning. If two rear-working synchro-spindles are specified, it is possible to set the machine for double-three machining, resulting in rapid output of less complex components with front and rear-end features.
Another development that increases efficiency is a small twin turret that can be mounted on a slide in five spindle positions. The turret contains static tools that can be changed within half a second. This hydraulically-controlled tool carrier is capable of operations that include roughing, finishing, threading and grooving.
Control is via the Index Industry 4.0-ready iXpanel with 18.5” touchscreen and Siemens S840D sl. The front-opening design of the multi-spindle machine, with its good accessibility and ergonomics, has been retained, as have various automation options that enable the MS32-6 to machine chucked parts. If producing from bar, a 3.3 or a 4.3 m magazine feeder is provided with the notable feature of a built-in drilling station, which allows the bar end to be drilled and gripped internally for precise guiding of the stock, rather than the pusher.
