Machine Tool Shaping: Components and Operation

Shaping in Machine Tools

Shaping, using a knife or cutting tool and alternative rectilinear movement, begins when the workpiece is set on the machine table.

Parties

Caucus

The body of the machine houses the cutting mechanisms and facilitates progress. It includes horizontal and vertical guides for the movement of the neck and head.

Vertical Slide

Slides along the horizontal guides, enabling alternative rectilinear movement.

Carriage Tilt

Rests on the front of the head and can rotate horizontally. On its
