Turning and grooving tools in use: one workpiece, five solutions

By Bhalchandra Chorghade, Editor, CNCTimes.com

Machining a complete component with as few tools as possible – that is the goal of many machinists. But especially with complex components of the drive system, several work steps are necessary and each of them brings its own challenges. Using the example of a drive shaft, we show five typical machining tasks and how you can solve them optimally and economically using our turning and grooving tools.

A frequent machining task, in which various turning and grooving tools are used, is the production of a drive shaft. Such drive shafts ensure power transmission in systems, machines and vehicles. This means that drive shafts are indispensable in many sectors, from the automotive and supplier industry to drive technology and mechanical and plant engineering.

These components, which later have to withstand the highest strength and toughness requirements, are often made of high-strength and alloyed steels. In our example this is 42CrMo4. The strength of this material is between 900 and 1200 N/mm 2 . Machining takes place, for example, on a turning-milling center. Safe internal cooling is recommended to prevent wear on the cutting inserts. This also prevents chips from getting stuck in the groove, for example, and leading to tool breakage. It is also important for a good surface quality that chips are transported away quickly and safely. In our machining example, internal cooling with an emulsion up to 40 bar is used.

The special features of the component are the tight tolerances. These are particularly important for subsequent further use. Because then there are additional components that are connected to our drive shaft as a counterpart via the splines, for example. How these exact edits are possible? Below you can see our solutions.
