6-2 CHAPTER 6: HYDRAULICS
ALPHA ST320 S2
1. GENERAL DESCRIPTION
The guiding concept of the ALPHA ST320 S2 feed system consists mainly in maintaining the bar
suspended in an oil bath.
The hydraulic pump injects the oil into the space between running bar stock and guiding channel
elements hence achieve functions below:
1. To keep the bar stock positioned at central of the channel.
2. To reduce friction between running bar stock and the guiding channel.
3. To absorb the vibration created during machining.
A pressure switch detects the pressure at the outlet of the pump. A level allows the monitoring of the
filling rate of the hydraulic tank.
