Common questions Z4 Milling Machine

VHF Z4 Milling Machine

It is a chairside milling machine, ideal for clinics that want to produce same-day restorations with full workflow control.

Yes, but in block format and with limited applications. The main focus is glass-ceramics and chairside materials.

Yes. This is one of its key differentiators, allowing for abutment production directly in the clinic.

The main difference between the Z4 and the E4 from VHF is the Z4’s ability to mill custom titanium abutments.

No. It features an internal compressor and touchscreen operation, allowing for quick use even by teams without advanced experience.
