Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

Fig. Helical milling vertical mode 370. The first advantage of this is the table does not need to be able to swivel. The second advantage of this is that whereas the table can only swivel to a maximum of about 50º, the vertical head can, sometimes, be tilted to nearly 90º.
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 multi-toothed cutter that is fed into the moving workpiece.
Explain the difference between a variable-speed head and step-pulley head. Variable-speed head must have the machine running to change the speed, and a step-pulley must be off and manually changed. True or False: Angles can be cut on a vertical milling machine by tilting the head.
This enables the use of all the Sherline accessories such as the faceplate, 3- and 4-jaw chucks, Drill Chuck, and centers with the indexer. A built-in mechanism detents the spindle every 5°, and there is also a red laser engraved collar that indicates rotation in 1° increments.

Title: Microsoft PowerPoint - How to Tram a Mill Head
Loosen those four bolts on the front of the head. On the left or right hand side of the mill (usually opposite swivel adjustment bolt), there MAY be a pin, to prevent the head from rotating beyond 20* or so. Older mills most likely do not have this pin, the Bridgeport at work …
How to use a divide head and rotary table. The divide head and rotary table are a device used to rotate the work piece around a third machine axis, this is usually referred to as the 'C' axis and is commonly used on milling machines or borers to provide the ability to easily create accurate single or multiple machining operations around a component.

Vertical milling machines have a spindle located vertically, parallel to the column face, and mounted in a sliding head that can be fed up and down by hand or power. Modern vertical milling machines are designed so the entire head can also swivel to permit working on angular surfaces.
For example, when you add a rotating machine table to a 3-axis CNC, the combination of rotation and vertical movement make it capable of milling threaded parts. It requires much more complex programming to effectively use a rotary table with your 3-axis CNC milling machine, and you’ll need CAM software to create programs.
