Makino presented the vertical 5-axis machining center DA500 at this year's EMO in Hannover. The DA500 can perform both milling and turning operations with a high degree of reliability and agility – a gain in productivity and, thanks to the pallet magazine, a maximum level of autonomy. This minimizes the number of clamping processes, improves machining accuracy, and saves time and money.
One of the biggest advantages of the DA500: Reliable, high-precision milling and turning operations can be combined on a single machine.
This eliminates the need for setups and the associated risk of errors, and cycle times are reduced. Makino's well-known strengths in volumetric accuracy over long machining times are maintained.
This makes the DA500 the perfect solution for a wide range of applications, including the manufacturing of engines for aerospace or semiconductors.
High precision and fast
Following the successful DA300 from Makino, the DA500 also features a symmetrical structure in its design to minimize thermal effects on the machine and maximize rigidity. At the same time, elements taken from Makino's a1 series, such as the slant bed design, have reduced inertia and increased the rigidity of the Z-axis.
The tool ring magazine with curve-controlled changer enables the fastest tool changes, while Makino's proprietary Two-Vision technology reduces the risk of clamping errors by the operator through visual checks of the tool and the workpiece. Linear scales with 0.05 µm resolution, a direct drive, and Makino's Super GI.6 control ensure optimal positioning and
Repeatability.
New spindle for the toughest working conditions
The working conditions in demanding manufacturing facilities place enormous demands on the spindle. For the DA500, Makino has therefore developed a new spindle - with 20,000 rpm, 50% more torque, double the power, and only one-third of the acceleration time of the D500 spindle. In combination with axis speeds similar to the DA300 (60,000 mm/min), the DA500 spindle delivers
excellent performance in fast milling operations with constant chip thickness. As a result, parts can be produced in very short processing times with minimal auxiliary times. Another key feature of the DA500 is the proven mantle cooling of the rotary table, which dissipates the heat generated at high table speeds. Thus, this rotary table has no usage time limitation, unlike other machines on the market that are limited to 30 minutes. Overall, the agility and chip disposal of this highly precise 5-axis vertical machine are
as good as with high-quality 4-axis horizontal machines.
Customer-specific automation
In today's production environments, automation is a crucial factor for manufacturers. For the DA500, Makino has developed an automation package that can be adapted to various configurations at the customer's facility, ranging from four pallets with a maximum workpiece size of 800 mm to eight pallets with a maximum workpiece size of 550 mm, or any combination in between. Above all, the compact pallet magazine allows for higher productivity while maintaining the same footprint, with the workpiece dimensions being the same for both the stand-alone machine and the configuration with the pallet magazine.
This automation package, specifically designed for long-term operation, features additional coolant nozzles for cleaning the pallet storage, thereby reducing maintenance and cleaning efforts. An extremely useful function is the Work Vision system, a vision processing system that scans the pallet with a camera above the clamping station and informs the operator when a workpiece is outside the maximum size limits. A stress-free automation solution and the long-term accuracy of the DA500 ensure reliable production over multiple shifts.
Turning without compromises
The strength of the DA500 lies in the fact that due to its special design, there are no compromises in milling performance for turning operations. The spindle bearing for turning tools has been specifically arranged to minimize the load on the front bearing while still maintaining the rigidity of the machine. The table rotates at up to 800 min-1 with high rigidity, allowing for operations on the DA500.
machining of materials such as stainless steel for use in semiconductor manufacturing or nickel alloys for engines in aerospace is possible.
