  The producers of panel saws tend to improve sawing accuracy and minimise a level of vibrations, to increase their competitiveness at the market. Mechanical vibrations in the main saw driving system, which level depend on a plethora independent factors, may really affect sawing accuracy and general machine tool vibrations. The objective of the research was to explore vibrations signals of the main spindle system, and to extract...

• The effect of a belt position in the spindle driving system on critical rotational speeds

  Publikacja

  • K. Orłowski
  • K. Duchnicz

  - Annals of WULS, Forestry and Wood Technology - Rok 2016

  The aim of this paper was to examine how the belt pulley position affects critical rotational speeds of the modernized spindle of the sliding table saw Fx3. Methodology of determination of critical rotational speeds of the spindle in a function of the spindle design features and its driving system is presented. Spindles in these kind of machine tools are mainly driven with V-belts, and the pulleys on the spindles might be positioned:...

  Producenci pilarek formatowych do drewna dążą do zwiększania dokładności przecinania. Można to osiągnąć np. przez poprawę zachowania się wrzeciona, gdyż od niego w dużej mierze zależą efekty przecinania. Przedstawiono metodykę wyznaczania prędkości krytycznych wrzeciona pilarki formatowej w funkcji cech konstrukcyjnych wrzeciona i jego napędu.
