Machine overview

Where can I find an overview over the K5? Is there a description of the K5?

With your K5 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 dry machining.

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. You can open and close the working chamber door manually.

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

  • To open or close the working chamber door, pull it upwards or push it downwards with your hand. Use the recessed grip of the door.

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

  2. Blank holder; Rotational axis A
  3. Fixing ring
  4. Spindle with collet chuck for picking up tools
  5. Tool magazine

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

Green

The machine is ready for operation.

You can open the working chamber door.

White

The machine is ready for operation.

The working chamber door is open.

Blue

The machine is operating.

The working chamber door is closed.

Red

A machine malfunction has occured.

The working chamber door is closed.

In the accessories container below the working chamber, you can store blanks, tools, and the spindle service set so they are easily accessible.

  • To access the accessories container, manually pull it out of the machine.

  • To close the accessories container, push it into the machine until it is completely closed.

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:

  • 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

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 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: CoCr
  • Tool status: new

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

  • Measurement according to ISO 3746, survey method 3

Established sound emission:

The identification plate of the machine contains identifying information such as the serial number. You can find the identification plate and machine serial number at the following location: Front side of the machine

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

Linear axes

The spindle moves along these axes.
