The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head. Although there are several other types of milling machines this document will focus only on the vertical milling machine. A milling machine removes metal by rotating a multitoothed cutter that is fed into the moving workpiece.
The position of the workpiece can be moved along all 3 of the machines working axes (X Y and Z). By advancing the workpiece into the rotating cutter material is removed and it is brought to the desired size and shape. Machine Specifications Spindle 2HP 604200 rpm Spindle Taper Size R8 Table Size 49" x 9" (equipped with 3 tslots)

Milling machines are very versatile. They are usually used to machine flat surfaces but can also produce irregular surfaces. They can also be used to drill bore cut gears and produce slots. The type of milling machine most commonly found in student shops is a vertical spindle machine with a swiveling head.
• This will help determine which way the head needs to be moved • CCW needle motion indicates the table is getting lower or the angle between the mill head and that side of the table is less than 90 degrees. • CW needle motion indicates the table is getting higher or the angle between the mill head and that side of the table is greater
One of the key alignments on a vertical milling machine is setting the vertical head so that it is square with the milling table. This has to be so it is square in the xz plane and in the yz plane. All vertical heads except on the smallest machines are designed so that they can rotate in the xz plane. This is a very useful feature.
Pedersen model vpu0 and I would like to convert it into a vertical milling machine.

In the simplest terms a lathe holds a workpiece on a rapidlyspinning chuck a cutting head or tools then moving along the length of the workpiece forming it into the correct shape. On a mill the workpiece is stationary clamped onto the bed of the mill in the case of a vertical mill. The rotating head then drills into the workpiece.
