ABSTRACT:
A pressure stabilizing apparatus is given which is capable of storing and supplying the volume of hydraulic fluid needed for rapid advances as well as accepting displaced hydraulic fluid required for rapid retractions in a barfeed apparatus. This pressure stabilizing apparatus or surge-accumulator device demonstrates the advantage of eliminating excessive force, which could damage the headstock, cause increased vibration and noise, and also prevents loss of contact with the bar end, all of which limit the speed of the spindle, and reduce productivity.
