The INTEGREXi-150 is not only capable, but smart: there is a 3D simulation that shows any interference before machining and the CNC "talks" to the operator during setup to assure it is done properly.
One of the approaches to machining that Mazak Corp. (www.mazak.com) has been promoting for the past few years is the "done-in-one" approach. Essentially, this means that rather than machining parts on several machines in sequence, parts are finished (or nearly so) on a single machine. Realize that in a machining operation the time of doing things other than removing metal (e.g., moving from one machine to another; queuing; waiting for tool changes) tends to be significantly greater than the job at hand (i.e., making parts), and this done-in-one method makes a whole lot of sense.
The Mazak INTEGREX i-150 is designated by the company as a "multitasking center." From the standpoint of the orientation of the main 5,000-rpm 5-hp spindle, horizontal, and a 6-in. through hole chuck, and the 2.56-in. bar capacity, one could nominally think of it as a turning center. But then that runs smack into the fact that there is an integral 10-hp, 12,000-rpm milling spindle that's mounted on the vertical, rotating B-axis, and things get a bit trickier nomenclature-wise. But at the end of the day (or shift) what really matters is the machine's capability, not what it is called. The B-axis has a roller cam, non-coupling design and an absolute feedback scale that provides not only highly accurate positioning, but five-axis contouring, as well, with a range of -10° to +190°. An interesting aspect of the machine that facilitates fully doing the job is the work-handling device that is sometimes used as an NC tailstock, and sometimes as a workholding vise that can pick up the part from the spindle, index it 45° or 90°, thereby permitting backside operations; it can also be used to unload finished parts onto a conveyor.
The machine has a rapid rate of 1,576 ipm in the X, Y, and Z axes (which are, respectively, 14.57, 7.87 and 17.13 in.) There is a standard 36-tool magazine that's front loaded for operator accessibility. Another benefit of this multi-capability machine: reduced floor space. The machine requires approximately 58-ft2.
For more straightforward but still rather impressive turning capability, there is the HYPER QUADREX 150 MSY, which is engineered to machine parts from 2.56-in. diameter barstock. This machine has two horizontally opposed spindles (main spindle has a 6-in. chuck, C-axis control, and 20-hp, 5,000-rpm turning capacity; the opposite has a 15-hp, 6,000-rpm turning capacity, and a 2-in. bar capacity) and two tool turrets (each handling 12 VDI-type tools) that have X, Y, and Z motions, and 7.5-hp, 6,000 rpm live spindles for milling, drilling and tapping operations.
The HYPERQUADREX 150 MSY has a 12.6-in. swing, 11.4-in. maximum machining diameter, and a 24.2-in. machining length. The machine provides a 0.0002-in. positioning accuracy in all axes; the repeatability is 0.00004-in. on X and Z and 0.00008 in. on Y. The C-axis accuracy is 15 arc seconds with a ±5 arc second repeatability.
