“…An automatic machine is a machine in which all the main and auxiliary movements necessary for the cycle of workpiece processing are automated, including loading and dispensing of the processed part. The worker should only periodically load a batch of blanks or bars and periodically control the dimensions of the parts [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Turret lathes, which are automated turret machines, are widely used in large-scale and mass production. The use of automatic machines in small-scale production, which has a significant specific weight in instrument construction, was considered inadvisable until recently due to the fact that their reconfiguration takes a lot of time. Currently, thanks to the expansion of processing methods, which allow with minimal time consumption to go from the production of one part to the production of another part of the same group, automatic machines are increasingly used in small-scale production. The introduction of innovative methods to expand the technological capabilities of machines should go not only by increasing the accuracy of processing, a wider use of the expansion of functionality can be realized by equipping with auxiliary devices that can perform operations that improve the production of parts. One of the ways to improve the productivity of the automatic lathe is to use shaped cutters, which allow you to process the part faster and with better quality, and with the help of developing a methodology for calculating and adjusting the cams. The expansion of the technological capabilities of automatic machines should not only go by increasing the accuracy of processing, a wider use of the expansion of functional capabilities can be realized by equipping them with auxiliary devices that can perform such operations that improve production. One of the ways to improve the productivity of the automatic lathe is to use shaped cutters, which allow you to process the part faster and with better quality, and with the help of developing a methodology for calculating and adjusting the cams. Therefore, the topic of the article is relevant.

Experimental studies of counterbalance valve for the hydraulic drive control systems of mobile machines are presented. According to the results of theoretical research experimental prototype of the counterbalance valve is developed. Experimental stands are elaborated, where leak tightness degree was studied and static characteristics were obtained. Dependences of operating fluids supply on the parameters of the pressure difference at its basic spool and load pressure are plotted. Transient processes in the hydraulic drive control system are analyzed, adequacy of the theoretical calculations to the elaborated mathematical models for the control system of mobile machine hydraulic drive is proved.Streszczenie. Przedstawiono badania eksperymentalne zaworu równoważącego w układach sterowania napędem hydraulicznym maszyn mobilnych. Zgodnie z wynikami badań teoretycznych opracowano eksperymentalny prototyp zaworu równoważącego. Opracowano stanowiska eksperymentalne, na których badano stopień szczelności oraz uzyskano charakterystyki statyczne. Narysowano wpływ zasilania płynów eksploatacyjnych na różnicę ciśnień na szpuli podstawowej i ciśnienie obciążenia. Przeanalizowano procesy przejściowe w układzie sterowania napędem hydraulicznym, udowodniono zgodność obliczeń teoretycznych z opracowanymi modelami matematycznymi dla układu sterowania napędem hydraulicznym maszyny mobilnej. (Charakterystyki eksperymentalne zaworu równoważącego układu sterowania napędem hydraulicznym maszyny mobilnej).

The subject of this article is the failed bushing used in the car suspension. The claim of the broken bushing came from the car producer. The main aim of this paper was to know if the failure was a green crack as evidenced by steam treatment oxide on the crack interfaces. To check, these items a Scanning Electron Microscope (SEM), hardness testers, and optical microscope were used. The density of the upper edge where the crack occurred was checked. Based on this investigation it was found that the crack was not caused by the rollover application.
