Unlike the two other L32 bar autos in the range, the 8-axis L32-X adds a Y2 axis to the Z2 axis on the back tool post. So does the 9-axis L32-XII, which additionally has +90/-45° B-axis swivel on the front gang tool post, where rotary tools can work at either spindle to produce angled holes. Both machines are available in 35 and 38 mm bar diameter versions, and may be used with or without the guide bush.
The L32 design is modular, enabling users to streamline their manufacturing costs by selecting functions that achieve the optimum machine configuration, while retaining the option of being able to add extra functionality later. A workpiece conveyor is standard. Control is via the Industry 4.0-ready Mitsubishi 800 CNC, which allows up to three tools to be in-cut at the same time.
Up to 44 tools for front, back and cross machining are available in the L32-X model, while the B-axis L32-XII version accepts four fewer. The speed range of the 3.7/7.5 kW main spindle and 2.2/3.7 kW counter spindle is up to 8,000 rpm. Both have a C axis for use in conjunction with driven tool stations in the three tool carriers. Fast acceleration of tool rotation up to 6,000 rpm minimises cycle times, while rapid traverse in the linear axes is 32 m/min, except in Y2, which moves at 24 m/min.
