Machine overview

Where can I find an overview over the R5? Is there a description of the R5?

With your R5 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 blank changerClosed Machine component which stores multiple blanks in a magazine and which can automatically load them into the working chamber.. When using the search, use a blank changer or a blank magazine instead of the R5 allows you to process up to 10 jobs in succession without having to start each job manually.

The machine is designed for wet and dry machining.

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

During dry machining, our anti-soiling concept reduces the soiling of sensitive machine parts.

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 with DentalCNC. You cannot open the door when the machine is switched off or while the axes are moving.

The multi-purpose compartment contains the following components:

You can open and close the multi-purpose compartment via DentalCNC .


The open multi-purpose compartment (discs not included)

  1. Blank magazineClosed Part of the blank changer in which you store the blanks for automatic loading.
  2. Cooling liquid tank
  3. Compressed air regulator (location depends on the series)

You can insert blanks and tools into the working chamber. This is where the blanks are machined.

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:

Color

Status

White

The machine is ready for operation.

You can open the working chamber door.

Blue

The working chamber door is closed.

Red

A machine malfunction has occured.

The working chamber door is closed.

To operate the machine, you must use a computer running Windows® (“CAM computerClosed The computer that is connected to your machine and which runs DentalCAM and DentalCNC.”) and specially designed software (“manufacturing softwareClosed Term for the software package consisting of DentalCAM and DentalCNC.”). The manufacturing softwareClosed Term for the software package consisting of DentalCAM and DentalCNC. consists of the following components:

  • DentalCAMA CAM application for creating and calculating virtual blanks (“jobs”)
  • DentalCNCA CNC application for machining jobs and for maintaining the machine.

To create and design the dental objects you also need a CAD application (sold separately by specialist dealers).

You may want to read the overview of the workflow in DentalCAM and DentalCNC.

The anti-soling concept decreases the soiling and wear of sensitive machine parts.

The anti-soiling concept does not replace the regular cleaning of the machine. Without regular cleaning, the machine life decreases significantly.

NOTICE

Machine damage when dry machining without an air extraction system

When dry machining, an operational external air extraction system must be installed. Otherwise, the machine will get soiled over time and become defective.

  • Always use a correctly installed and operational external air extraction system during dry machining.

The anti-soiling concept consists of:

Dry machining

  • The external air extraction system An external suction unit creates a vacuum in the working chamber and sucks machining residues out of it.
  • Air blown into the working chamber Keeps machining residues away from the spindle and other machine parts.
  • The internal vacuum sensor Constantly monitors the vacuum in the working chamber
  • The ionizer The ionizer electrically discharges machining residues of certain materials to reduce their dispersion in the working chamber.

Wet machining

The cooling liquid keeps machining debris away from sensitive machine parts.

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

This machine has 5 axes: 3 linear axes and 2 rotational axes.

Linear axes

The spindle moves along these axes.
