FIELD: instrument making. ^ SUBSTANCE: head contains a body installed with the capability of rotating around the axis, support, bearing a cutting instrument and which moves with the help of the transmission mechanism along the relatively oriented axis of rotation in the radial direction of the axis of movement relative to the body and to compensate the support and the cutting instrument's dis-balance, at least two counterbalancing bodies, which with their centres of mass protrude on the side of the axis of movement and forcibly turn relative to the support and body. To reduce the control force for the movement of the counteracting support of the body installed with the capability of turning around the immobile relative to the support axis of rotation and is forcibly directed relative to the body at a distance from the rotation axis. ^ EFFECT: use in machines with compensation for dis-balance. ^ 39 cl, 12 dwg |
