Angular momentum pumps are very often used in cooling circuits of medium and high power engines, power plant boilers as well as bilge, ballast and firefighting installations. Such an extensive use of angular momentum pumps on board is connected with their numerous advantages. However, during operation the wear of marine hull, the rotor and shaft seals take place. The research attempts to increase the service life of shafts. The article presents the research results of pump shaft pins after finish lathing. The research was performed on a roller 60 mm in diameter made of X5CrNi18-10 steel. The finish tooling of pump shaft pins was carried out on a universal CDS 6250 BX-1000 centre lathe. The finish lathing process was carried out by means of Sandvik Coromant cutting tool with replaceable inserts. In the research of lathing, process used inserts with Wiper technology. During the lathing, the optimal cutting parameters were used for inserts: CCMT09T302WF, CCMT09T304WF and CCMT09T308WF. The cutting process was performed at side angle of 90° ± 3°. The process of lathing used cutting tool dynamometer DKM 2010. During the research, the effect of cutting tool geometric on surface roughness parameter Ra of steel applied to marine pumps shaft pins was determined. The article presents the research results of material ratio parameters. In addition provides an examples shaft surface profile analysis and material ratio. Measurement of surface roughness and material ratio parameters was performed by T8000 profilometer.

One of the greatest problems of modern production techniques is the achievement of an appropriate quality at minimal costs and accompanied by the production efficiency increase. Therefore while designing the production process, the technology used should have a considerable influence on the durability and reliability of machine parts to be produced. During finish treatment the final dimensions as well as functional properties are imparted to a given element by application of proper treatment type. The engineer has a range of production techniques to choose for the proper surface layer formation. It is crucial to find a suitable solution which will meet the requirements as well as the work conditions of a given machine part. The article presents the research results referring to the analysis of the influence of finishing lathing on the cutting forces and surface roughness of stainless steel. The research was performed on a roller 60 mm in diameter made of X5CrNi18-10 steel. The finish tooling of pump shaft pins was carry out on a universal CDS 6250 BX-1000 centre lathe. The finish lathing process was carried out by means of Sandvik Coromant cutting tool with replaceable inserts. During the research, the effect of cutting tool geometric on cutting forces and surface roughness of steel applied to marine pumps shaft pins ware tested. In addition, the influence of cutting tool geometric on cutting temperatures was determined.

Jednym z najważniejszych problemów współczesnych technik wytwarzania jest zapewnienie odpowiedniej jakości wyrobu, przy minimalizacji kosztów i jednoczesnym wzroście wydajności produkcji. W związku z tym podczas projektowania procesów wytwarzania powinno się zastosować technologię, która ma istotny wpływ na trwałość i niezawodność części maszyn. Podczas obróbki wykończeniowej nadawane są ostateczne wymiary i właściwości użytkowe danego elementu. Osiąga się to poprzez zastosowanie odpowiedniego rodzaju obróbki oraz dobór właściwych parametrów danego procesu. Technolog projektujący proces kształtowania warstwy wierzchniej ma do dyspozycji różne techniki wytwarzania. Konieczne jest znalezienie określonego rozwiązania, które będzie odpowiadać wymaganiom i warunkom pracy danej części maszyny. W artykule przedstawiono wyniki badań wpływu zmiany kąta przystawienia noża tokarskiego typu Wiper podczas toczenia czopów wału na parametry chropowatości powierzchni. Badania przeprowadzono na wałku o średnicy 60 mm, wykonanym ze stali X5CrNi18-10. Obróbkę wykończeniową czopów wału przeprowadzono na tokarce uniwersalnej kłowej CDS6250BX-1000. Podczas badań wykorzystano nóż tokarski z wymiennymi płytkami skrawającymi: CCMT09T302 WF, CCMT09T304 WF, CCMT09T308 WF o promieniu naroża 0,2 0,4 i 0,8 mm. Zmianę kąta przystawienia realizowano w zakresie ±3º. Proces toczenia wykonano siłomierzem DKM2010.
