Valves

A short overview on valves. In piping technology, a valve is a piping component which influences the fluid flow by opening, closing, diverting, mixing or partially obstructing the passage through itself. Valves are broadly classified according to their fields of application, e.g. power plant valves, heating valves, gas and food-grade valves.

Feed Rate Calculator

When milling or drilling, or creating a tool path for a CNC machine the feed rate must be determined. Materials have rated surface speeds for a given type of cutter. The harder the material the slower the speed. Given the diameter of the tool and the surface speed, the RPMs of the spindle can be calculated.
