The ball joint parts made of forged steel are quite important in the suspension system. The quality of production of ball joint parts is very important because of their role. Some basic defects can be found in the hole edge form. These defects affect the hole quality of ball joint parts. In this study, the effects of cryogenic processing on the wear of AISI D2 punches and the effects of punch wear on the hole edge geometry of hot forged AISI 1040 steel ball joint parts were investigated. The hole geometry changes are generally associated with punch wear and process parameters. For the purpose of investigation, piercing was carried out using an eccentric press with AISI D2 tool steel punches on 6.0 mm-thick ball joint pieces. The punches were traditionally heat treated. Some of the punches were cryogenic-treated at -145 °C in addition to the conventional heat treatment. Weight loss values were measured to assess the punch wear, and SEM and OM images were analysed. At the end of the industrial piercing process, it was found that the D2 tool steel punch wear decreased with cryogenic process applied and the size changes in the hole edge geometry of the punched 1040 hot forged steel parts turned out to be less marked.

“…Among the first researchers that have studied the influence of the clearance between active elements upon the burr's size, were Tisley and Howard back in 1958 and Jimma and Sekine in 1990 [5]. The researches that were carried out shown that besides active elements clearance, the part's quality is also being influenced by other parameters that are related to the sheet metal raw material stamping.…”

The sheet metal bearing cages quality obtained through punching is influenced by a variety of factors related to the punching mechanism construction, to its adjustment onto the press and also to the technological parameters of the punching process itself. This paper refers to an experimental research study applied to a real industrial environment, which analyzes the sheet metal bearing cages obtained through punching. The paper informs about the main results which were obtained during researches regarding the influence of clearances between the active parts of the punching mechanism upon the dimensions of the punched bearing cages windows burrs. The study presents also some information about results interpretation and several related conclusions.
