The guiding concept of the ALPHA 552 barfeed system consists mainly in maintaining the bar suspended
in an oil bath.
The hydraulic oil is contained in the machine itself. Aspirated by a pump motor, it is injected into the front
rest and the guiding blocks. A pressure switch measures the pressure at the outlet of the pump.
A level allows the monitoring of the filling rate of the hydraulic tank.
