Applying the grinding technique to steels requires guidelines and proper implementation of tools and inserts to achieve quality results.
Steel has been thoroughly used by a lot of manufacturers and metalworkers nowadays.
The almost perfect feature of steel makes it pass all rigid requirements when it comes to mechanical properties and excellent grade.
Steel is fused with different elements that have excellent characteristics on their own – alloyed together to form one solid metal that can withstand high performance applications.
Steels are the best materials for withstanding high temperature environments that require high tensile and yield strength and excellent resistance to corrosion and oxidation.
Steels are iron-based metals. By its improved strength, steels are common raw materials used for manufacturing parts for automotive engines, aircraft structure and turbines, and even for chemical plants and medical tools.
Steel materials are challenging to be machined compared to other metals due to its kind of hardness feature. The higher the steel’s alloying content, the harder it is to machine. Mostly, this challenge falls to austenitic steel which contains a maximum percentage of chromium and nickel elements. But special metallurgical treatment has been made to enhance the machinability of steels.
In addition, hard steels need the rigid use of heavy machineries when machining. There is a need to obtain knowledge of the factors contributing to the machinability of steels to achieve complex precision engineered parts in high volumes. Mechanical properties, grades, alloyed elements, and strength are just four of the contributing factors that influence the machinability of steels.
Obtaining finer surface finish in grinding steels involves continuous abrasive metal removal. Thus, an implementation of healthy guideline to grinding steel is necessary especially when grinding hard, course part. For such operation, there are key variables to be followed such as: three-point positioning, consistent grain dressing, proper automation, and coolant application. Keeping a close watch to those key variables makes the operation running in a smooth flow, enabling to achieve that consistent part results in a single pass!
Since the operation is too continuous and rapid, tool grains on the grinding wheels might get worn out so redressing them is highly encouraged. To gain that precise surface finish and tight diameter tolerance, grinding procedure should be put properly into place.
