TYPES OF MACHINING IN LATHE

What are machining around?

The machining around are operations that are carried out by means of chip removal to a part to give it a specific shape, such as, for example, the reduction of the diameter of a cylinder (cylindering) or when the part is completely finished, we resort to separating the excess material using the parting operation.

Types of machining around

Mechanized types

Displacement

With this operation, the exterior of the part is machined to reduce its diameter or to remove any imperfections it may have.

Displacement

Facing

Mainly it consists of machining the front part of the piece to remove imperfections, inclinations or also to reduce its length.

Facing

Boring

As the name implies, it is practically used when a part needs a drill, to achieve this operation, it is necessary to put a bit in the tailstock of the lathe and advance slowly.

Reaming

A tool called reamer is used and is used to make surface finishes or to make larger holes with greater precision (the holes must be previously made with the drilling operation)

Reaming

Boring

It is used as a method of enlarging or improving the quality of an existing hole.

Chamfering

It is an operation by means of which a recess is made to the edges of the material.

Bucking

This operation is used when the part is completely finished and serves to separate it from the excess material.

Bucking

Screwed

Although we are too familiar with parts that have ropes, it is difficult to make them on a lathe, unless it is a CNC lathe where you are programmed to automatically thread.

Screwed

Grooved

It consists of opening grooves of variable width and depth in the pieces.

Grooved

Conical turning

It consists of machining the part in the shape of a cone.

Knurled

The tool called «knurling» is used and is used to mark the outer surface of the material, in order to increase the manual grip of the piece.
