Specialized WET block mill for glass ceramic & pre-milled — same-day dentistry — Volume × precision × ease — restorations in about four hours.
The W4 is DEPRAG's 4-axis WET Milling machine purpose-built for glass-ceramic and pre-milled work. A 20-position, four-sided super holder with a zero-point change System lets a lab mill up to 20 blocks in one load, so multiple crowns, inlays and veneers run without frequent stops — supporting scan-to-seat workflows in roughly four hours. A 2.5 kW, Ø62 mm Water-cooled spindle and integrated casting body keep output stable, while C5-grade ball screws, P-grade guideways and hybrid-ceramic bearings (<3 µm) deliver 5 µm repetition and 0.01 mm accuracy. (An external compressor is required.)
For a practice or lab scaling glass-ceramic and pre-milled work, the W4 hits the sweet spot: a 20-block super holder for batch runs, lithium-disilicate-grade precision, and a simple WET-only workflow on a compact 130 kg body. It is the machine that turns frequent outsourcing of single units into same-day, in-house production.
