14. Vertical Knee Traverse Crank. The vertical knee traverse crank is connecting part of the vertical knee with the machine arm. 15. Saddle. The saddle is part of the machine that becomes the cradle of the table. The saddle is located between the knee and milling machine table, which is square and has a 's tail shape that is in pair with ...

In Vertical Milling Machine, there is a multi-point cutting tool called milling cutter. this machine has vertical spindle which is perpendicular to the work piece. In Vertical Milling Machine, the head is used to swiveled or it can be fixed. this can move in upward and downward directions and can move in any directions.

Mill Machining, Milling Process, Horizontal & Vertical Milling Machines Definition. Milling is a process performed with a machine in which the cutters rotate to remove the material from the work piece present in the direction of the angle with the tool axis. With the help of the milling machines one can perform many operations and functions starting from small objects to large …
