VMC Reduces Machining Time for Complex Production Parts

In Booth 1218, Makino, Inc. (Mason, OH) displays their DA300 vertical machining center, their latest 5-axis machining system that provides the ideal blend of speed, precision and flexibility for complex part applications. Inspired by the best design characteristics from both vertical and horizontal machine platforms, the DA300 delivers the highest productive capabilities for multi-axis workpieces in the smallest of machine footprints. These features make the DA300 ideal for single setup, multi-side accessibility, or full-contouring capability to tackle a wide variety of complex production part applications found in industrial hydraulics and pneumatics, optical, electrical and semiconductor components, medical and dental products, die-cast parts, automotive components and aerospace parts.

The DA300 comes standardly equipped with a 20,000 rpm HSK-A63 spindle, delivering the speed and flexibility to tackle high speed, highly productive machining of various workpiece materials, including aluminum, die-cast, steel and titanium. Acceleration and deceleration to and from full speed can be accomplished in a mere 1.5 seconds, reducing chip-to-chip times. Additionally, the machine’s standard configuration includes a 60-position ring-type automatic tool change (ATC) magazine with capacity for a wide variety of tooling, as well as a Vision B.T.S. to verify the integrity of the tooling prior to use. Optional 230-tool and 445-tool capacity ATC configurations are also available. DA300 specifications include:

With a perfect blend of the proven stability of the FANUC hardware and Microsoft Windows Embedded Standard 7 OS, the state-of-the-art Professional 6 (Pro6) control helps move operators fluidly through machine setup, empower them with easily accessible information and protect them with enhanced safety. Included are the unique GI Milling and GI Drilling G-code functions, which cut down on wasted motion and time by cutting corners out of toolpaths. While not every tool can make use of these functions, advanced motion control GI is proven to reduce overall cycle time by 3 percent to 8 percent in typical production components. This reduction saves substantial cost in both high-volume and low-volume production environments by reducing the number of spindles required and freeing up machine availability to take on more work.

Designed to eliminate interferences in accessing the pallet, the DA300 can be configured using several approaches, including direct part handling as a stand-alone machine, manual handling using a table chuck and pallet, one of the workpiece pallet systems (WPS) or third-party automation using an EROWA chuck and pallet system. The DA300 can be field modified to add multiple pallet magazines, starting with a seven-pallet workpiece pallet system (WPS-7), and up to a 19-pallet workpiece pallet system (WPS-19). These configurations deliver the highest productive capabilities using minimal floor space.
