Milling

Milling is a highly flexible machining method used for precise and complex parts. This Lexicon entry explains different milling techniques, from 3-axis to 5-axis machining, and their relevance for sourcing decisions. Tailored for technically-minded buyers.

• Manufacturing process

  All processes for the production of geometrically determined bodies with predetermined technical properties and dimensions are referred to as manufacturing processes. In addition, material-changing methods such as hardening or soft annealing also belong to the manufacturing processes. Under the preamble of manufacturing methods, the individual methods are divided into six main groups according to their common features. These are described in more detail in DIN 8580 and categorized in subgroups and process variants. Manufacturing processes serve both for the production of semifinished products for further processing and for the production of final products.

• Milling

  Milling refers to a cutting which is used for manufacturing components with a specific geometric contour. Thanks to its high efficiency, productivity and precision, milling is particularly popular in metal-processing production technology. The milling can be used both for the processing of planar surfaces and for the production of complex, three-dimensional contours. A milling tool with geometrically determined cutting edges is used and, during the milling process, material is removed from a workpiece by a rotating circular movement. Milling can now be carried out both manually and using state-of-the-art CNC machine tools with a high degree of automation.

• Con rod

  A connecting rod is also referred to as a connecting rod or push rod and connects the crankshaft to the piston in a crank drive. The connecting rod converts the linear movement of the piston into a linear oscillating axial movement and thereby allows the force transmission in the vehicle train. As a rule, connecting rods are made from C70 steel or from microalloy steels. In addition, compensation steels or titanium are also used in the sports motor sector. Connecting rods in large series are frequently forged, sintered or cast, whereas in productions with small numbers a cutting production of metal pieces is preferably used.
