Poor or Improper Maintenance. CNC machines need to be carefully cleaned and lubricated on a regular basis — otherwise, problems can begin to arise. A lack of cleaning could lead to a buildup of dirt and debris. This might seem to be purely a hygiene issue, but it can have real implications in the machine's output.
The lower end (suction side) of a pump is connected to the hydraulic reservoir, the upper end is connected to the remaining circuit. The dark upper triangle in these hydraulic symbols indicates fluid going out of the system and hence represents a pump. In the case of the hydraulic motor, the dark triangle is inverted indicating that the fluid ...
Many different types of hydraulic circuits are used in machine tools. For controlling the flow of the fluid in hydraulic systems various designs of cylinders, pumps, hydraulic motors, valves and many others are used. In circuits with variable delivery pumps, or motors, the cutting speed and the rate of feed can be regulated by reducing or ...

Other machines that make use of hydraulics include vehicles on construction sites. Diggers, cranes, bulldozers and excavators can all be run by robust hydraulic systems. A digger, for example, powers its massive arm with hydraulicpowered rams. The fluid is pumped into the thin pipes, lengthening the rams and, by extension, the arm.
Breather filters are placed on hydraulic reservoirs to prevent atmospheric contamination from entering. Air enters the reservoir whenever the fluid level drops. This occurs during normal cycling of the machine, and when fluid cools down during idle periods. Breathers are designed to stop particles larger than 3 µm from entering the system.

Part 1 of this series, covering hydraulic cylinders, is in Design Data Sheet 28. The purpose of the present issue is to suggest circuit arrangements which will minimize the tendency of an air cylinder to "chatter" or move erratically when operated at a slow rate of travel. Air cylinders are essentially power, not feed, devices.
