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, heavy-duty gang milling operations.

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.
Belt Length . When the head and tail pulley are the same size: L=(D+d)/2 x 3.1416+2C When one pulley is larger than the other pulley: L=(D+d)/2 x 3.1416+2C+(D-d) 2 /4c. Belt Speed. Expressed in feet per minute (FPM) S=D x RPM x .2618 x 1.021. Belt Load. At one time when the load is known per square foot: P= G 1 x C(in feet)x W (in feet)

Belt properties determine the conveyor belt's primary applications. For example, mining and milling industries commonly use rubber to handle bulk materials including raw ore and aggregates. Grocery stores commonly use PVC conveyor belts, and airports may use neoprene, polyester, or rubber for luggage handling.
Oct 30, 2010· do you mean variable belt drive or geared head? a BP J head is a belt driven with manyally changed step pullys and a V belt, a 2J variable speed BP is still a belt drive but it uses a variable pully that changes speeds for you with a crank. A gear head mill is normally a larger machine like a Cincinnati or K+T etc. Just a bit of educational input.
A belt hardens twice again faster each time its operating temperature increases another 10 degrees Celsius (18 °F). This is an insidious problem because if a belt slips just a little, it generates heat—the belt's enemy—and it does so precisely at the belt's mating surface! A harder belt slips even more, which generates still more heat.
