July 5, 2018 –Makino announced the D200Z 5-axis VMC. The Makino D200Z 5-axis vertical machining center combines machine movements and accuracies with software developments for motion control. From roughing to high-speed finishing of multifaceted, contoured 3-D geometries, the D200Z boosts productivity with the most competitive processing capabilities for complex dies and molds typically found in the automotive, injection molding, packaging, medical and optical markets.
Designed with an integral chuck to maximize work-zone volume and load capacity, the D200Z accommodates workpiece sizes up to 300mm in diameter and 210mm tall with weight up to 75 kg. The X, Y and Z axes (350mm, 300mm and 250mm travels, respectively) provide movement with traverse and cutting feedrates of 60m/min. The D200Z has also adopted a B-axis tilting structure with 180 degrees (0 to +180) of tilt capability at 100 rpm. Both the B-axis and rotational C-axis (360 degrees continuous at 150 rpm) feature direct-drive motors for responsive angular and rotational operation.
The design of the D200Z is 1500mm wide by 2220mm deep. All machine elements and peripheral equipment are strategically located within the main body of the machine to limit the overall machine footprint. Both the standard 20-tool capacity automatic tool changer (ATC) and the optional 40-tool ATC fit within the same machine floor space. In addition, the machine tool magazine capacity can be optionally expanded to 100 and 300 tools.
Wide base castings and core-cooled ballscrews serve as a base platform for all other machine components. The machine’s 30,000-rpm, HSK-E50 spindle is designed with a spindle core and jacket cooling system to control thermal growth, deflection and vibration during machining operations.
An integrated pallet chuck reinforces the stiffness and rigidity of the machine tool. Additionally, this design has a common pallet interface that can be readily integrated into a variety of automated cells and systems prevalent in today’s tool, die and mold shop environments.
The D200Z can also be configured with a graphite machining package to provide 5-axis production of graphite electrodes.
