WO/2016/112443 METHOD AND TOOL FOR MACHINING CYLINDRICAL HOLES||WO||21.07.2016|
||PCT/BG2015/000003||GD INZHENERING EOOD||MAKSIMOV, Yordan|
The invention can be used in machining cylindrical holes in metal structural elements which are subject to cyclical external effects. The present method includes mounting a workpiece and carrying out plastic deformation using a tool (100) which is inserted into the hole to be machined (8) and moved in the direction of the axis thereof such that the working portion of the tool passes completely through the hole and is then withdrawn therefrom. What is characteristic is that the workpiece (4) is mounted by means of clamping same with a clamping force F between two supports (1) and (5), one or both of which are moveable and each of which is provided with a hole (45) which is larger than the hole to be machined (8). The tool is characterized in that it is provided with a resilient deforming element (27), which is compressed as the tool (100) is withdrawn in a direction opposite to the direction of insertion. The main advantages include an increase in the fatigue life of a machined structural element and a reduction in the axial force required for reverse movement.

The invention relates to the field of mechanical engineering, and more particularly to lubricants in a general sense and to the maintenance of automotive vehicles by means of checking the oil and fluid therein. First, a sample of oil from the relevant unit or assembly of the vehicle is drawn into the chamber of a syringe. Then, said sample is compared with a reference sample of new oil or fluid of the same grade and type as the sample drawn. The two samples are compared visually with regard to the density of the fluid and the presence of mechanical impurities. This comparison is made by rubbing, identifying impurities, and noting the nature of or a difference in colour.
