DVF 4000 5-Axis Vertical Machining Center for Compact, High-Precision Parts

The DVF 4000 is a DN Solutions simultaneous 5-axis vertical machining center built on a traveling column design for high-precision work on compact, multi-sided parts. It carries a 15,000 RPM direct-drive spindle rated to 18.5 kW (24.8 hp) and 117.8 Nm of torque, a 400 mm rotary table with 200 kg load capacity, and simultaneous X/Y/Z/B/C-axis control that keeps a part in one setup instead of several. A 40-tool double-arm ATC and DN Solutions' CUFOS control with a 19-inch touchscreen round out the standard package. Ellison Technologies, the largest DN Solutions distributor in North America, supplies the DVF 4000 as part of its full 5-axis lineup within its machining centers offering, for shops moving from 3-axis or 3+2 work into full simultaneous 5-axis production on smaller parts.

Aerospace and Precision Structural Components

Small aerospace brackets, housings, and structural components often need multiple compound-angle features cut to tight tolerance without the stack-up error that comes from repositioning the part. The DVF 4000's simultaneous X/Y/Z/B/C-axis control and 620 x 440 x 430 mm travel handle these features in a single setup, while absolute glass scales on X, Y, and Z and Z-axis thermal compensation hold dimensional accuracy through longer production runs. Shops supplying aerospace manufacturers use the machine's 0.008 mm positioning accuracy to cut down on inspection rework on close-tolerance brackets and fittings.

Medical Implants and Precision Devices

Orthopedic implants and small surgical components need sub-0.01 mm accuracy and a clean surface finish straight off the machine, with minimal handling to avoid contamination. The DVF 4000's 0.008 mm positioning accuracy and 0.005 mm repeatability, combined with through-spindle air for chip and coolant control on sensitive parts, let medical device manufacturers machine implant geometries in one setup instead of splitting the job across separate roughing and finishing operations.

Mold, Die, and Semiconductor Tooling

Mold cavities, die components, and semiconductor process parts all require complex 3D surfaces machined to a tight finish spec, often in hardened tool steel that tests spindle rigidity. The DVF 4000's 15,000 RPM direct-drive spindle and roller LM guideways keep deflection low on finishing passes, and the standard 40-tool double-arm ATC, expandable to 60 or 120 tools, keeps a full range of roughing and finishing tooling on hand for automotive mold work and semiconductor component runs without a mid-job tool change stop.

High-Speed Spindle, Smarter Thermal Control, and Automation Built-In

The DVF 4000’s direct-coupled spindle is available with 15000 RPM and delivers up to 18.5 kW of power and 118 N·m of torque. Spindle cooling and integrated thermal compensation are standard, ensuring dimensional stability during high-speed cuts or extended production. For shops looking to scale, DN Solutions offers automation packages like AWC (8–12 pallets) and Multi-AWC (up to 40 pallets) to increase spindle uptime while maintaining compact floor space.

Features like Smart Thermal Control, pulse encoders, and rotary encoders on B/C axes further enhance machine intelligence, and with Renishaw or Blum probing options, the DVF 4000 is fully capable of closed-loop feedback control for tool and part measurement.

Built for Intelligent Machining, Not Just Metal Removal

With CUFOS controls, the DVF 4000 offers advanced conversational programming (EZ Guide i), real-time monitoring, and intuitive touchscreen operation. Operators benefit from helpful features like Adaptive Feed Control, Spindle Warm-Up, and detailed tool management dashboards. Paired with IKC (Intelligent Kinematic Compensation), the machine maintains positional accuracy even during complex multi-axis moves, which is vital for aerospace-grade tolerances.

Add-ons like mist collectors, through-spindle coolant, and high-capacity tool magazines (40–120 tools) make this model highly customizable for a wide range of industry demands.

FAQ Section

What is the DVF 4000 used for?

The DVF 4000 is a DN Solutions simultaneous 5-axis vertical machining center used for high-precision milling of compact, multi-sided parts in a single setup, including aerospace brackets, medical implants, and mold and die components. Its traveling column design, 15,000 RPM spindle, and CAT 40 tooling suit shops producing small to mid-sized parts that need tight tolerances without the setup time of separate 3-axis operations.

How does the DVF 4000 compare to the rest of the DVF Series?

The DVF 4000 is the smallest and most compact model in the DVF Series, built around a 400 mm rotary table and 200 kg table load. The DVF 5000 steps up to a larger table and higher spindle speed, and the DVF 6500 and DVF 8000 move up further with larger tables for heavier parts. Buyers choose the DVF 4000 when shop floor space and smaller part size matter more than maximum table capacity, since the core simultaneous 5-axis architecture carries across the line.

What types of parts is the DVF 4000 best suited for?

The DVF 4000 handles small to mid-sized, multi-sided parts that need complex geometries or 5-face access machined in one setup: aerospace brackets, medical implants, mold cavities, and semiconductor components. Its 620 x 440 x 430 mm travel and B-axis tilt range of -30 to +110 degrees reach undercuts and angled features that would need a second setup on a 3-axis mill.

What control does the DVF 4000 run?

The DVF 4000 runs DN Solutions' CUFOS control, a PC-based system with a 19-inch touchscreen, conversational programming, and CPS (Collision Protection System) for real-time collision prevention in automatic and manual modes. It includes 40-gigabyte program storage and 1,000-block look-ahead processing for complex 5-axis toolpaths.

What is the maximum spindle speed and tool capacity of the DVF 4000?

The DVF 4000's direct-drive spindle runs at 15,000 RPM with 18.5 kW (24.8 hp) of power and 117.8 Nm of torque, using a CAT 40 Big Plus taper. It ships standard with a 40-tool servo-driven double-arm ATC, expandable to 60 or 120 tools, with a 1.3-second tool-to-tool and 4.6-second chip-to-chip change time.
