Abstract: A device for keyway broaching is provided with a housing, a drive shaft, a broaching carriage received and supported in the housing, a tool support connected to the broaching carriage, and a crank drive that couples the drive shaft and the broaching carriage with each other. The broaching carriage, when driven by the drive shaft, performs an oscillating movement comprising a cutting movement and a return stroke. A sleeve is arranged between the housing and the broaching carriage. A first seal is provided between the housing and the sleeve and/or between the sleeve and the broaching carriage. The tool support is connected to the broaching carriage with a rocking lever interposed between the tool support and the broaching carriage. The drive shaft has a control section that controls a relative movement between the rocking lever and the broaching carriage.

Abstract: A thread whirling device 1 and a whirling ring 3, corresponding thereto, are presented, in which the whirling ring 3 can be attached in a hollow spindle 11 of the thread whirling device 1 in a simple and reliable manner using a combined bayonet-type and clamping connection.

Abstract: A sliding block 31, a tool carrier 1 and a tool holder 3 are presented, providing a high-precision interface that is also adjustable. As a result, very exact positioning of the tool arranged in the tool holder 3 in relation to the tool carrier can be achieved. The repeat accuracies lie below five micrometers.

Abstract: A system is proposed that is made up of a tool holder 1, a collet 15 with a clamping nut 19, and a tool insert 27, in which the collet 15 and the tool insert are fixed and positioned on various function surfaces within the tool holder 1. Nevertheless, the clamping means are the same, namely a thread on the tool holder 1.

Abstract: A tool support for a machine tool has a clamping surface. A positioning device for a tool holder is provided that is positioned at the clamping surface. The positioning device has at least one conical element wherein a longitudinal axis of the conical element extends orthogonally to the clamping surface. The conical element is a conical bore or a conical pin. The tool holder is equipped with complementary conical elements so that a positive-locking, precise positioning of the tool holder relative to the receiving bore in the tool support is ensured.

Abstract: The invention relates to a device for holding tools (13) on machine tools, comprising a tool receptacle (1) and a tool holder (6). Clamping elements (4) are used for fixing the two parts. According to the invention, the device is configured in such a way that both the tool holder (6) of a first type and the tool holder (6) of a second type can be adapted. The tool holders (6) of the first type meet the HSK standard while the tool holders (6) of the second type, for the purpose of shortening the length, do not have any receptacle (11) for a clamping system as it is required for tool holders (6) of the first type.

Abstract: A tool support for tools on machine tools has a tool support receptacle and a tool clamping insert arranged in the tool support receptacle and receiving a tool. At least one clamping screw secures the tool clamping insert in the tool support receptacle. The tool support receptacle has at least one continuous threaded bore having an axis that is positioned angularly relative to an axis of rotation of the tool. The at least one clamping screw when screwed into the at least one threaded bore engages in a tightened state a radial circumferential outer surface of the tool clamping insert.

Abstract: A tool head for securing a tool in a machine tool has a stationary spindle bearing housing, a spindle rotatably supported in the spindle bearing housing, and a modular tool changing insert for receiving a tool. The tool changing insert is exchangeably arranged on the spindle or a holder. An internal cooling medium supply device supplies a cooling medium directly from the spindle bearing housing into the tool changing insert. The cooling medium supply device preferably supplies the cooling medium laterally into the tool changing insert via an auxiliary housing.
