The machine tool, also, will present design constraints to the spindle. The amount of available space in the head, cost considerations, complexity and market demands will affect the ultimate spindle design. Cost will have a significant impact on the final spindle design. A very sophisticated and capable spindle design will not be acceptable on a lowcost machine tool. Consequently, an advanced

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. 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.
