Premium 5-Axis Control for High-Tolerance Part Production

The DVF 6500 from DN Solutions is engineered for manufacturers requiring extreme precision, speed, and rigidity in a compact 5-axis platform. Designed with a traveling column architecture, oversized roller guideways, and simultaneous X/Y/Z/A/C-axis control, it enables full-contour 5-axis machining for complex part geometries. A robust rotary table handles up to 1,000 kg workpieces with diameters up to 840 mm and heights of 500 mm, making this machine ideal for aerospace, medical, and die/mold components that demand tight tolerances and fine surface finishes.

Power, Speed, and Stability in One Platform

The DVF 6500 is powered by an 18,000 RPM spindle with 22 kW of output and 118 N·m of torque. It features ball screw shaft cooling, Z-axis thermal compensation, and oversized roller guideways to minimize deflection during aggressive cuts. The A-axis travels ±120° and the C-axis offers full 360° rotation, enabling precise tool orientation at any angle. The high-speed motion system delivers rapid traverse rates of 45 m/min on X/Y/Z and rotary feeds up to 7,200 deg/min — all supported by intelligent compensation systems that ensure accuracy even during prolonged high-speed machining.

Intelligent Thermal and Motion Control for Long-Run Accuracy

Advanced accuracy features include absolute linear glass scales on XYZ axes and absolute rotary encoders on A and C axes. Z-axis thermal sensors feed into proprietary software that compensates for heat-induced distortion. The result is consistent micron-level accuracy across long cycles. The base casting is a single Meehanite iron structure for vibration dampening, and the dual roller gear cams on A/C axes provide superior rigidity under heavy tool loads.

Automation and Tool Management for Unattended Machining

The DVF 6500 includes a servo-driven double-arm ATC with options for 60 or 120 tools. It supports CAT40 and HSK63 tool interfaces and allows maximum tool lengths of 300 mm and tool weights up to 8 kg. The machine is fully Renishaw probe ready with laser tool setting, spindle probing, and automatic calibration via Intelligent Kinematic Compensation (IKC). Optional integration with hydraulic fixturing and multi-axis part clamping makes it automation-ready for lights-out manufacturing.

Clean Operation, Coolant Management, and Chip Control

For extended unattended production, the DVF 6500 includes through-spindle coolant, air-blow systems, flushing nozzles, and a 172-gallon (650L) flood coolant tank with chip conveyor and mist collector. The system is designed to maintain clean cutting conditions and thermal balance even during high-volume chip generation. Optional high-pressure coolant systems and external filtration are available for fine-particulate or exotic material applications.

FAQ Section

What sets the DVF 6500 apart from other 5-axis machining centers?

The DVF 6500 combines high-speed 5-axis cutting with massive workpiece capacity and advanced motion control. Its 1,000 kg table load, integrated thermal compensation, and dual-roller gear cam rotary drives give it superior performance for long-run, high-precision parts. Whether machining titanium aerospace brackets or injection molds, it offers a rigid and responsive cutting platform designed for accuracy and uptime.

Can the DVF 6500 be automated for lights-out machining?

Yes. The DVF 6500 is fully prepared for automation with hydraulic fixture prep, Renishaw probing systems, and optional high-capacity ATCs. Its closed-loop feedback with Intelligent Kinematic Compensation allows for autonomous calibration and tool monitoring. This makes it ideal for unattended production environments requiring reliability and repeatability over long cycles.

What types of parts is the DVF 6500 best suited for?

It excels in machining complex 3D components that demand multiple angles, tight tolerances, and exceptional surface finishes. This includes turbine housings, orthopedic implants, semiconductor parts, and mold cores. Its table diameter (650 mm) and vertical clearance (500 mm height) allow it to handle both wide and tall parts without repositioning.

How accurate is the DVF 6500 during long machining cycles?

The DVF 6500 uses Z-axis thermal compensation, ball screw shaft cooling, and absolute encoder feedback to maintain ±0.008 mm positioning accuracy and ±0.005 mm repeatability. Its proprietary compensation algorithms ensure consistent tolerances during long machining runs. This level of control is critical for shops producing high-value parts where rework or scrap is not acceptable.

What tool changer options are available?

You can choose from a 60-tool or 120-tool automatic tool changer. Both use a servo-driven, double-arm mechanism and support CAT40 or HSK63 holders. The ATC system accommodates tools up to 300 mm long and 8 kg in weight, and features random-access selection for faster cycle times. This flexibility allows operators to handle both heavy-duty roughing tools and small finishing tools without sacrificing productivity.
