Precision instruments at TU Dresden
Private lecturer Dr. Thomas Nagel, an engineer, is group leader for precision mechanical constructions at the Institute of Precision Mechanics and Electronics Design of the TU Dresden. In the scope of his lecture "Construction elements", he gives an assignment on this topic every semester. Several miniature plain bearings of the iglidur® series were used each time. The best results of the last 3 years can be seen here.
Assignment 2008
The biomaterials are stored in various containers, which should be supplied manually or semi or fully automatically in the process. For this documentation, a miniature rotary table has to be developed for the accommodation of 10 test tubes of the size ∅6 x 35 mm, whereby only one sample is made available at a time in the handling area. The other samples are covered by the housing. The rotary table should be propelled in the specified direction by means of the step motor which is linked to an electronic control system. When a button is operated, the table turns to the exact position of the sample and stops there, so that the sample can be picked up.
Assignment 2007
For a portable ticket machine, the paper feed should be implemented via the drive of the print roller. The speed of the paper should be precisely vx mm/s. A rotary step motor of the type UAG2 is provided as drive, which is operated by an electronic control system of the SAMOtronic- uni type with a widely adjustable frequency.
Assignment 2006
A linear axis should be implemented, which can move a carriage in a linear horizontal range of movement of 0-50 mm. Several buttons and switches provide the necessary commands to the control system.
