FIELD: process engineering. ^ SUBSTANCE: set of inventions comprises revolving tool depth adjuster (RTDA) and revolving tool incorporating said device. RTDA comprises adjusting element travelling along spindle axis, intermediate element attached thereto and travelling toward working depth, and working element revolving relative to intermediate element between locked position and unlocked position to inhibit withdrawing the RTDA from tool body. Intermediate element has hooking element turning toward unlocked position to hook tool body when working element turns into locked position. When working element turns into unlocked position, aforesaid hooking element disengages from tool body to withdraw RTDA from tool body. Revolving tool comprises RTDA, revolving spindle and tool tip. Adjuster axis of revolution is parallel with tool tip axis. ^ EFFECT: higher accuracy and ease of adjustment. ^ 23 cl, 8 dwg |
