Helical of Spiral Milling in Indexing: One of the important indexing operations to be performed on milling machine is the helical or spiral milling. Generation of flutes on twist drills, milling of helical and spiral gears, milling of worms and cutter, etc. are some of the examples of this class.
A milling machine is basically used for shaping, routing, boring, and drilling metals and other solid materials. Generally there are two categories of the milling machine which include the vertical type and the horizontal type. In order to optimize the capacity of the milling machine, it is essential to identify the appropriate milling machine type for specific tasks.
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, heavyduty gang milling operations.
