Technical data: Side-by-side comparison

The following tables give you an overview of the technical data of vhf dental machines.

The technical data in this document are only valid for machines which are delivered at the publishing date of the document and onwards until further notice. The technical data of older machines may vary. To determine the technical data of an individual machine, see the original operating instructions that were provided with the machine.

You can find the technical data as well as additional prerequisites for machine operation in the operating instructions.
When you obtain the external CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC., regard DentalCAM & DentalCNC‘s system requirements.
