Product Description


Wet Dental Mill

Roland DG now offers a wet-milling device for the precise and uncomplicated production of glass ceramics and composite resins. The DWX-4W produces crowns, bridges, inlays and onlays, and veneers at high-speed with its Jaeger DentaDrive spindle and simultaneous 4-axis milling and offers unattended milling convenience and increased efficiency with the option of loading up to three standard pin-type blocks at a time. Featuring Roland DG’s famous reliability and product support, it’s the ultimate in affordable and dependable milling technology.



Distinguishing Features
High-performance 60,000-RPM Jaeger DentaDrive spindle
Combines ball screw-driven 4-axis milling with simple one-button operation
Multi-pin clamp mills up to three different pin-type materials at a time
4-axis simultaneous milling to support undercuts
4-station Automatic Tool Changer (ATC) to change burs without interruption

Maximum Convenience
The DWX-4W combines simultaneous 4-axis milling with simple one-button operation. Color-coded LED status lights signal machine status and alerts the operator to any change in machine status that helps save time and materials and enables lab technicians to carry out the milling process with confidence. In addition, the DWX-4W features a 4-station Automatic Tool Changer (ATC) that changes grinding burs as needed without interrupting the production process for a high-efficiency workflow.

Virtual Machine Panel
Unlike traditional CNC mills, Roland DG has replaced the complex controls with a user-friendly Virtual Machine Panel (VPanel) that operates machine diagnostics and the calibration and milling processes from your computer desktop. The VPanel also tracks tool, spindle time and milling progress, and provides a reminder when daily collet maintenance is needed, and tracks overall machine time for maintenance purposes.



Coolant Compartment and Water Filtration<.
The DWX-4W is equipped with a fully integrated pump and coolant system. The coolant container slides in and out, making it exceptionally easy to replace the coolant on a regular basis. It also features an integrated water collection filtration system for maintaining a clean and efficient workspace.

CAM Software Included
Purchase of the DWX-4W includes open-architecture CAM software that accepts all STL file types and supports the milling of relevant materials. This easy-to-use software features a user-friendly interface and simple workflow that promotes a short learning curve. Its features include automatic nesting and placement options to help maximize efficiency and pre-defined milling procedures for direct software-to-mill functionality without interruption during tool path calculation.

Growth Potential
Highly scalable, the DWX-4W offers multicast capability that allows connection of up to four Roland DG machines to one computer, making it easier than ever for dental labs to expand their businesses and increase their production capacity. The DWX-4W wet mill lets labs control the entire process in-house with a single software seat, maximizing your investment and resources.
