Machine overview

Where can I find an overview over the Z4? Is there a description of the Z4?

With your Z4 you can machine blanks of different materials to create high-quality objects for the dental sector. You can find a list of the materials which you can process with the machine in the manufacturing softwareClosed Term for the software package consisting of DentalCAM and DentalCNC..

The machine is designed for wet machining.

During wet machining, the tools and blanks are constantly being cooled by cooling liquid.

The screen in the working chamber door of your machine responds to touch. You can use it to operate the machine by selecting icons on the user interface and to receive information about jobs, tools and the machine status.

A section of the user interface

The working chamber door locks the working chamber and protects the user from injuries during operation.

The working chamber door is operated by electricity. You can open and close the door via the touchscreen or with DentalCNC. You cannot open the door when the machine is switched off or while the axes are moving.

  6. Measuring sensor
  7. Webcam

Colors of the working chamber lighting

If the working chamber lighting is insufficient, provide additional lighting.

The machine illuminates the working chamber in different colors. The color will change depending on the state of the machine. You will find the colors and respective machine status in the following table:

  2. Cooling liquid tank
  3. Cover of the cooling liquid tank with strainer basket
  4. Space for tool magazines

This machine is designed for an integrated CAD / CAM workflow which allows you to manufacture restorations with the following components:

*not provided

You can use the touchscreen for standard operation and basic maintenance.

If you do not use an integrated CAD / CAM workflow, you will need to access Windows® on the CAM computerClosed The computer that is connected to your machine and which runs DentalCAM and DentalCNC. during standard operation to directly work with DentalCAM & DentalCNC.

The actual sound emission of the machine varies heavily depending on the manufacturing material and the machining conditions.

  • If the machine is exceptionally loud, check the following operating conditions:
  • Cleanliness of the blank holder
  • Condition of the tools
  • Quality of the blank
  • If loud noise cannot be avoided, wear ear protection during machining.

Sound measurement

Measuring conditions:

  • Machined material: IPS e.max (Block, C14)
  • Tool status: new

  • Measured value: Sound pressure level (distance: 1 m)

  • Measurement according to ISO 3746, survey method 3
