Chapter 2: Common Issues he Quick Load Servo 65 / 80 is designed to be a user-friendly, simple, and reliable bar feeder, covering a range of diameters 6 to 65 / 80, depending on the machine purchased. Although easy to use, including extremely quick changeovers and the capability for unmanned operation this unit is not flawless.
Vibrations Description: The term “vibration” is being used regarding the Quick Load Servo 65 / 80, to indicate that the RPM performance of the lathe is physically deteriorated, to the point of creating an unbalanced rotational oscillation of the bar stock, within the confines of the spindle of the lathe that is detrimental to the machining process.

“Feed with help of the turret” application must be selected. It is recommended by LNS that when feeding without the help of the turret that a dead-length, parallel gripping type clamping device be used. This type of clamping system will prevent the bar stock from moving forward when the clamping device is closed, thus losing the positioning accuracy.
