The invention relates to the transmission of power and/or data from/to a stationary part of a machine tool 200 to/from an accessory 100 mounted in the spindle 210 of the machine tool 200. A first electrical link or interface 1a,1b,1c,1d provides electrical communication between the stationary part 200 and the spindle 210, and a second electrical link or interface 3 is provided electrically connected to the first electrical link at the accessory mounting area 230. The second link 3 is in the form of electrical contacts. The invention extends to an accessory shank 360 for mounting to the spindle 210 of the machine tool, and also to an accessory 100 e.g. in the form of a measurement probe, connected to the said shank 360.
A machine tool comprising a stationary part and a spindle rotatable relative to the stationary part, the spindle having a shank receiving area for releasably accepting the shank of a cutter or other machine tool accessory, and comprising a first electrical link between the stationary part and the spindle, and a portion of a second electrical link at the shank receiving area in electrical connection with the first link for providing in use a disconnectable electrical link between the spindle and the shank, wherein the portion of the second link is in the form of a least one electrical contact, wherein the first link is an inductive link having complementary inductors which in use of the machine have relative displacement, one of the inductors being mounted to the spindle and the other of the inductors being mounted to the stationary part.
A machine tool comprising a stationary part and a spindle rotatable relative to the stationary part, the spindle having a shank receiving area for releasably accepting the shank of a cutter or other machine tool accessory, and comprising a first electrical link between the stationary part and the spindle, and a portion of a second electrical link at the shank receiving area in electrical connection with the first link for providing in use a disconnectable electrical link between the spindle and the shank, wherein the portion of the second link is in the form of at least one electrical contact, wherein the at least one electrical contact is in the form of a “C” shaped conductive element mounted to a non-conductive block at the shank receiving area.
