High speed five axis VMC

Share This Post

Makino has introduced the D200Z five axis VMC.

From roughing to high speed finishing of multifaceted, contoured 3D geometries, the D200Z enhances productivity with competitive processing capabilities for complex dies and moulds typically found in the automotive, injection molding, packaging, medical and optical markets.
“With mold manufacturers strained for capacity and challenged to keep pace with new design changes, all while minimizing costs, the need for high performance five axis machining has never been more critical,” said William Howard, vertical product line manager at Makino. “The speed and precision of the D200Z supply a unique foundation for responsive high speed cutting and outstanding surface finishes that reduce or eliminate handwork. Its 30,000 rpm spindle and integral direct drive table provide quick, precise, full five axis machining. All of this capability is tied together with Makino’s proprietary SGI.5 motion control software for the highest degree of accuracy and quality in the blends and matches of intricate surfaces and 3D accuracy requirements typical of today’s die, mould, medical and intricate geometry components.”
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 swift movement with rapid traverse and cutting feed rates of 60m/min. The D200Z has also adopted a unique, lightweight 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 agile, accurate, high-speed, responsive angular and rotational operation.
Wide base castings and core cooled ballscrews serve as a base platform for all other machine components, enhancing process stability. The machine’s 30,000 rpm, HSK-E50 spindle is designed with a high tech spindle core and jacket cooling system to tightly control thermal growth, deflection and vibration during high speed machining operations. This enables the D200Z to extend tool life and enhances surface finishes even in applications requiring fine tool blends and matches.
An integrated pallet chuck reinforces the stiffness and rigidity of the machine tool, while ensuring efficient workpiece changeover speed and full usage of work zone and workload capacities. The design has a common pallet interface that can be integrated into a variety of automated cells and systems prevalent in today’s tool, die and mould shop environments.
The D200Z can also be configured with a graphite machining package to provide high speed, accurate and productive five axis production of graphite electrodes.
