reikäsorvaus

Reikäsorvaus, also known as boring, is a machining process that enlarges a pre-existing hole or creates a precise hole within a workpiece. It is a form of turning performed on a lathe. The process involves a cutting tool that moves along the axis of rotation of the workpiece, incrementally removing material to achieve the desired diameter and surface finish. Reikäsorvaus is distinct from drilling, which creates a hole from solid material.

The primary purpose of reikäsorvaus is to achieve a high degree of accuracy in hole diameter, straightness, and concentricity. It is often used as a finishing operation after drilling or casting to achieve tight tolerances required for fitting shafts, bearings, or other components. The process can also be used to create internal tapers or complex internal profiles.

Key equipment for reikäsorvaus includes a lathe, a boring bar (which holds the cutting tool), and a cutting tool. The workpiece is held and rotated by the lathe's spindle, while the boring bar is advanced linearly. The depth of cut and feed rate are controlled to achieve the desired material removal and surface quality. Different types of cutting tools, such as single-point tools or specialized boring heads, can be employed depending on the material being machined and the desired outcome.

Reikäsorvaus is a versatile process used in various industries, including automotive, aerospace, and general manufacturing. It is essential for producing precision components with accurately sized and finished internal features.
