Dualunit Milling Workflows Boost Dental Lab Efficiency

Parallel milling cuts changeover bottlenecks

The main operational constraint in mixed-material production is the cleaning required when a single machine moves from wet milling to dry milling. Residual coolant and dust must be removed before materials such as zirconia can be processed, adding time and limiting machine availability.

By pairing a wet milling unit such as the DGSHAPE DWX-4W with a dry milling unit such as the DWX-52D, laboratories can run both processes in parallel. The arrangement allows glass ceramics and composite resins to be handled separately from zirconia, PMMA, PEEK and CoCr, supporting more continuous production.

Open architecture supports software choice

Equipment openness remains a key consideration when selecting a milling configuration. The DGSHAPE DWX series uses an open architecture, allowing laboratories to choose commonly used CAD/CAM software, scanners and material suppliers. That flexibility supports compatibility and potential future expansion.

DWX-4W: precision wet processing

The DWX-4W is designed for high-precision restorations and can hold three standard pin blocks at once. It is used for crowns, inlays, onlays and veneers. Its virtual machine panel, known as VPanel, simplifies operation, while the automatic tool changer allows operators to focus more on design work and less on machine setup.

DWX-52D: higher-volume dry processing

The DWX-52D is a widely used dry milling machine built on five-axis simultaneous control. Its Snap-in fixture system is intended to improve the efficiency and safety of material setup. The unit is positioned for stable processing of zirconia and metal sintering materials in higher-volume laboratory production.

Operational considerations for dual-machine adoption

For laboratories pursuing greater efficiency, combined procurement of the DWX-4W and DWX-52D can offer cost savings and process improvements. Before upgrading, laboratories should assess existing CAD/CAM software compatibility and ensure operators are familiar with the VPanel system to make full use of the dual-machine configuration.
