The wand is a highpressure remote hydraulic cylinder that is plumbed to a footswitchactivated pump. After the fixture is cleaned of debris and the operator mounts a new part, a shutoff valve—located in the circuit just after the fixturemounted booster—is opened. The operator then inserts the wand into the booster.

A hydraulic press is a machine press that generates compressive force by the use of a hydraulic cylinder. It is a device that is used for lifting heavyweights with the application of a much smaller force. The hydraulic press was invented by Joseph Bramah in England. He accomplished the project in the 17 th century (1795).

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.
