A high-precision two-part flat chuck device includes: a base, a cylinder, a sliding plate, a first clamping plate and a second clamping pate. A piston rod of the cylinder is connected with the sliding plate. Precision sliding rails are arranged at two sides of the base, and two sides of the sliding plate are respectively matched with the precision sliding rails in a sliding manner. An accommodating groove is arranged in a middle part of the sliding plate. The first and second clamping plates are symmetrically distributed in the accommodating groove along a center of the sliding plate, and a spring is arranged between the first and second clamping plates. Side surfaces of the first and second clamping plates are inclined planes, and chucks matched with each other are arranged at end parts of the first and seconding clamp plates.

The present invention relates to a tool carrier 62 for a machine tool, in particular a lathe, having a rotary shaft drive for a numerically controllable rotary shaft B for rotating the tool carrier 62, a first tool turret head 62A carrying tools, rotatably mounted around a first turret axis, and a second tool turret head 62B carrying tools, rotatably mounted around a second turret axis, the first tool turret head 62A and the second tool turret head 62B being positioned on opposite sides of the tool carrier 62 with respect to the axis of rotation of the rotary shaft B. The present invention also relates to a machine tool, in particular a lathe, having a tool carrier 62 of this type.

A working head for a cutting machine having a frame, and a cutting disc assembly supported by the frame. The cutting disc assembly having a cutting disc and a first driver rotatably moving the cutting disc around an axis of rotation of the cutting disc. A milling cutter assembly is supported by the frame. The milling cutter assembly has a milling cutter and a second driver that rotatably moves the cutting disc around an axis of rotation of the cutter.
