The new four-axis CNC 1 5/8” bar machining center with a subspindle that uses a three-sided tool platen featuring nine live tools (three on each side), six stationary drill holders, eight turning holders plus a separate cutoff toolholder for parts production at one location. A third axis combined with gang tooling allows the model 42-9 LSS to function as a productive alternative to standard two-axis gang tool lathes or lathes with turrets, the company says.
The 24 tools in a small area is said to minimize the travel distance from tool to tool for faster parts production while the addition of the Y axis allows for easy tool centerline adjustment through simple tool offsets. The main spindle has a 1 5/8" collet capacity and the subspindle has 1 3/16" collet capacity. The main spindle can be fitted with a 6" chuck and the subspindle with a 4" chuck. Both the main spindle and subspindle are servo driven and can be programmed for profile synchronization. Both spindles are located to 0.1 degrees (3,600 points). The machine design uses a 10 to 15 hp servo main spindle drive, a 2.6 to 3.5 hp servo subspindle drive and Mitsubishi servodrives for all axis movements. The control has a 10 1/2" flat color monitor capable of six-axis simultaneous interpolation. The control has 96 tool registers for tool assignments and tool offsets in all axes. Programs are compatible with programs using standard "G" codes and "M" functions.
