Ballizing Process

The analysis of this work was based on oil has significant effect on the surface finish as compared with kerosene, graphite by weight in oil as a lubricant. A pre-machined surface roughness could be finished and improved surface hardness was obtained.It was found that the response surface model made it possible to visualize overall metal cutting economy and to study optimum conditions of Ball burnishing. The result was improved fatigue life. Using  factorial design, the surface roughness models were obtained. The Ball burnishing parameters(for force evaluation )considered were speed, feed and the force. The result obtained was improved surface finish by force and lubricant. Alloy Al material can not be machined properly on conventional and even on CNC machine.The balls are located inside, are made of hard material The balls are free to move with the movement of the work piece due to frictional engagement between their surfaces. When balls are pressed against the surface of metallic specimen, the compresses pre-calibrated springs. The springs are used to reduce the possible sticking effect of the Balls and also to measure the applied vertical Ball burnishing force with help of the depth nut. Rotating in the clockwise direction, the load is applied on spring through steel body. This tool includes ball bearings and flat-ended springs. The finishing  and Ball burnishing tool is designed in a simple manner so that it can be mounted easily on lathe machine. The analysis of variance technique The trial numbers  were at corner points and obtained by varying high and low values of the diffrent parameters (for force evaluation). Centre points were obtained by keeping parameters (for force evaluation) at centre values to minimize the error under dynamic loads are based on inducing residual compressive force per unit area in the boundary layer. These include heat treatments such as hardening and Nitriding but also shot peening and ball Ballizing. Chip removal processes such as up cut milling or a well-matched grinding process can also induce significant residual compressive force per unit area in a component. It is only in the case of deep rolling that all three effects combine whereby this process can bring  about extraordinary high increases in dynamic strength. Ball rolling can be applied to all  metallic materials. The areas of application currently extend from steels and cast materials to lightweight alloys such as Aluminium Alloy, and mild steel.
