Five-Axis Dental CAD/CAM Milling Machine for Zirconia Crowns - DDM-5A Model

The bottleneck was always the manual finishing on zirconia crowns — too much handwork, too much variability between techs, and we were losing about a day per case just on milling step alone.

What we needed was something that could handle wet and dry milling in one pass without us having to swap setups, and the DDM-5A does that — basically you load a zirconia block, pick your mode, and it runs through the full contour without you touching it again.

The five-axis head gives you A-axis rotation at 360° and B-axis at 25°, which means you can cut undercuts and complex internal geometries that a four-axis just can't reach, and the repeatability is 3μm so teh fit on the die is consistent case after case.

Spindle speed runs form 15,000 to 60,000 rpm depending on the matrial — for zirconia you'll typically run it toward the higher end, but for PMMA or wax you can drop it down — and it uses a pneumatic automatic tool changer with three bur positions (0.5mm, 1.0mm, 2.0mm) so you don't have to stop and swap by hand.

It's a 95kg steel-frame unit with water cooling, dimnesions about 415×588×578mm, and it needs a clean oil-free air supply at 4.5 to 6.0 bar — we usually have stock but confirm lead time if you're ordering outside standard quantities, since MOQ can shift with demand.

Also worth knowing: it's certified ISO and CE, but it's not really built for high-volume on ceramics — better suited for small labs doing 20 crowns or so per day, and the 3-bur magazine means you'll be changing tools more often than on a 6-bur machine, which is a trade-off you should factor in.
