Abstract: The working performance of a spring-type quick-stop device (QSD) was experimental researched. The specimen at the chip root was obtained by using the device, and the adiabatic shear band of the saw-tooth chip was investigated. A high-speed camera was used to record the movement track of the tool rod of the spring-type QSD. The initial velocity and acceleration of the tool rod tip was calculated. The influence of the workpiece rotation and tool feed of the tool quick-stop experiment was discussed. The influence of Metal deformation inertia was qualitatively discussed too. QSD experiment on disc shape workpiece sample was carried out on lathe by orthogonal cutting. The adiabatic shear band in cutting zone was studied by saw-tooth chip roots received and made into metallographic specimen. The spring type QSD can be used instead of explosive type QSD. The device can effectively obtain the chip root sample at a certain cutting speed and cutting layer thickness.
