Toothbrush Simulation ZM-3.8 & ZM-3.12

 

Field of application

The device simulates various brushing movements on the surfaces of teeth and test pieces.

Functional Principal

Up to a maximum of 8 (12) specimens are simultaneously exposed to abrasion in the tooth brushing machine. The individual specimens may be of various forms and materials (hardness), and may be loaded with various levels of contact pressure. The specimen chambers are separated from each other so that each specimen can be operated with its own liquid (e.g. toothpaste-water mix), and individually cleaned. All the brushes are controlled by a central drive system, and the chosen type of movement is therefore the same for all specimens used in the trial. A high-grade motion controller guarantees exact speeds and trajectories which can be adjusted with a very high degree of precision. The motion sequence (teeth cleaning technique) can be freely selected from a combination of forwards, backwards and circular movements. Complex motion sequences can be easily programmed by means of an optional software module.

Chief advantages

  • Efficient and time-saving with 8 (12) specimen chambers able to be used simultaneously
  • Free choice of cleaning motion combinations in the X and Y axes (only X, only Y, circular and zigzag)
  • NEW: The speed of the brushing motion can be adjusted from 1mm/s up to 60mm/ s
  • Robust construction giving a high level of stability and reproducibility, and quiet running without intrusive noise levels.
  • Contact pressure over a range of weights from 50 g to 300 g
  • Contact pressure individually adjustable for each of the specimen chambers
  • Any type of brush can be easily attached with screws
  • Specimen holders can be cheaply made to individual customer specification
