DWX-4 Dental Milling System

The industry’s most cost-effective and user-friendly dental mill, the DWX-4 is a small dental milling machine that produces single crowns, copings, bridges and hybrid abutments with precision and ease. The DWX-4 is the ideal device for labs and practices just getting into digital milling. With the DWX-4 dental milling machine, you can quickly and economically mill on-demand in a wide variety of materials, including the latest composite resins.

Distinguishing Features

  • Mills wax, zircona, PMMA and composite resins in standard blocks and pin-types
  • Combines simultaneous 4-axis milling with simple one-button operation
  • Automatic tool changer with two tools for unattended milling (four tool option available)
  • Mill up to four different pin-type materials simultaneously with an optional multi-pin clamp
  • Multicast connection of up to four DWX dental mills to one computer

Mill with Confidence and Ease

The DWX-4 Dental Mill is designed for simple operation so that users can quickly set up and start creating precision prosthetics right out of the box. It combines simultaneous 4-axis milling with simple one-button operation and offers intuitive features such as a colour-coded LED light that signals machine status and an automated tool changer which provides two tools for precision unattended milling from start to finish.

Powerful Production Capabilities

The DWX-4 includes an automatic tool changer for two tools, and can be enhanced with the addition of an optional four-position automatic tool changer which supports up to four different tool sizes.

With an optional multi-pin clamp, the DWX-4W can mill up to four prosthetics in a single production run. The additional multi-pin clamp mills different pin-type materials simultaneously and saves time, labour and costs.

Compatible with Multiple Materials

The DWX-4 Dental Mill is equipped to mill standard blocks and pin-type materials, including wax, PMMA, zirconia and composite resins. Composite resins, such as VITA ENAMIC® are acclaimed in the industry for their superior strength and aesthetics. They can be finished without firing, which dramatically reduces labour and production time.

Connect Multiple Machines

Highly scalable, the DWX-4 offers multicast capability that allows you to connect up to four Roland machines to one computer, making it easier than ever for dental labs to expand their business and increase production capacity. The DWX-4 Dental Mill lets labs and practices control the entire process in-house with a single software seat, maximising your investment and resources.

Virtual Machine Panel

A user-friendly Virtual Machine Panel (VPanel) provides advanced controls so users can operate all machine diagnostics, calibration and milling processes from a desktop. The VPanel also tracks spindle time, tool and collet time, and overall machine time for maintenance.

Clean Milling Area

An integrated air blower* prevents excessive dust buildup, while a negative ion generator reduces static electricity when milling PMMA. A dust collection sensor prevents the machine from starting if the vacuum is inadvertently left off.

*requires air compressor

Economical Open Architecture

The open architecture of the DWX-4 enables production with the latest materials, CAD/CAM software and scanners so you’re not limited to the technology you can use. If you already have a production solution, the DWX-4 works perfectly with your existing scanner and compatible CAD/CAM software and eliminates reliance on a single source for materials. Compatible with RML-1 and NC code, the DWX-4 interfaces with your computer through a USB connector.
