#CMT# #/CMT# The spindle has an axially profiled shaft collar and a thread section (25), where a tool is screwed on the thread section. An axial shaft collar profile has a left-hand thread flank section (35) of a rectangular thread and a slot (37) and rotates the flank section and the slot. An axial load shedding ring profile has two left-hand thread flank sections (65, 66) of the rectangular thread and a lug (67) and rotates the flank sections and the lug. The lug is extended in the slot, which is wider than the lug. #CMT#USE : #/CMT# Tool holding spindle i.e. coolant containing hallow shaft, for holding a drill bit in a triple-thread core drill machine. #CMT#ADVANTAGE : #/CMT# The axial load shedding ring profile has two left-hand thread flank sections of the rectangular thread and the lug, and rotates the flank sections and the lug, where the lug is extended in the slot, which is wider than the lug, thus enabling safe, wear-free screwing of the tool on the spindle with less energy expenditure. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front sectional view of a tool holding spindle with a shedding ring. 25 : Thread section 35 : Thread flank section of axial shaft collar profile 37 : Slot 65, 66 : Thread flank sections of axial load shedding ring profile 67 : Lug. |
