What Is The Purpose Of Using Milling Machine
A milling machine removes metal by rotating a multi-toothed cutter that is fed into the moving work piece. Most milling machines are equipped with power feed for one or more axes. Power feed is smoother than manual feed and, therefore, can produce a better surface finish. Power feed also reduces operator fatigue on long cuts.

Difference between Meter In and Meter Out Circuit
In the meter-out circuit, the flow control valve is connected in the secondary line, directly after the load. In this circuit, speed control is achieved by changing the flow adjustment of the flow control valve, which controls the flow coming out from the piston rod end of the cylinder. Meter out circuits is used in drilling …
