The M series of combination lathes is useful for mixed-volume, short-run operations as well as in high-volume applications.
With a swing of 16.9" and a distance between the centers of 43.46", the M17 combines turning and machining capacity within a compact, 107.09" × 49.76" footprint. Rapid traverse rates of 394 ipm (X axis) and 295 (Z axis) translate to accelerated machine cycle times and reduced non-cut time, which increases the overall throughput, the company says. An optional automatic electric drum turret offering a 0.48 second station-to-station indexing time is available. The turret holds eight tools with pockets for square toolholders and bolt-on ID toolblocks.
The MI 7 has a cast iron "H" bed design. The guideways are induction hardened and ground and feature a Turcite-coated carriage and cross-slide that ensure rigidity, the company says.
The lathes also include a belt-driven cartridge-style gearless headstock that has a 10-hp AC GE Fanuc "P"-type spindle motor with a variable speed drive. This permits spindle speeds as low as 375 rpm. Three spindle options allow users to match the spindle speed and size to specific production needs.
Other noteworthy features include an automated lubrication system; a coolant system with splashguards; a Fanuc 2Li-T; manual cutting; and G-code programming.

This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
