The TB-25-LYMB Y-axis multitasking center's X, Y and Z axes move independently and do not have the problems associated with "axis on axis" stacking. The X, Y and Z axes are 90 degrees apart from each other and do not require movement of two axes to enable Y-axis motion. This kind of design makes the machine a turning center a four-axis machining center in one. Using conventional programming techniques, it can run as a turning center and a four-axis machining center, all in one program. This enables reduction of processing time by 56 percent on parts that require turning and off-center milling, drilling and tapping.
This single-spindle machine has a 10" chuck with a swing of 21" and a turning length of 24". It has a bar capacity of 2.5" and a full travel tailstock, allowing the capability of chuck work, bar work and shaft work. The turret has 12 stations with radial drive VDI-40 tooling. It is a servo-driven turret allowing for greater accuracy, repeatability and reliability. The main spindle motor is a 20-hp integrated motor drive with a 3,500-rpm spindle.
The twin-spindle version has a second spindle with an 8" chuck, 10 hp and a spindle speed of 5,000 rpm. The advantage of this two-spindle machine against others is the turret design containing 24 VDI-40 tools, which can be used on either the main or second spindle. This added tool feature gives greater flexibility in complex part processing, the company says.
The machine is equipped with a tool setter to enable reduction of setup time on complex parts involving fixed and rotating tools. It has provisions for untended running using bar feeders and parts conveyors on single machines. Traverse robots for loading and unloading between multiple machines can be used to enable machine cells augmented by auto-measuring and compensation.
