Estimating the term…
A rotary tool for machining workpieces, said tool comprising a base body having a clamping section and a tool head comprising a cutting region having at least one cutting edge. The tool head comprises at least one coolant channel for supplying a cooling and/or lubricating fluid into the cutting region. At least some sections of the coolant channel have a cross-section that tapers in the direction of the tool head. In this region, at least two coolant outlet lines branch off from contact points of the coolant channel in the direction of the tool head upper surface, and are offset in the axial longitudinal direction of the coolant channel. Also, a production method for a rotary tool, in which the blank of the tool is produced by a sintering method in which the coolant channel of the tool is formed integrally in the sintering method at the same time.
A lathe tool for machining workpieces, said tool comprising a base body having a clamping section and a tool head which comprises a cutting region having at least one cutting edge, the tool head comprising at least one coolant channel for supplying a cooling and/or lubricating fluid to the cutting region, the coolant channel having a cross-section tapering across the complete length of the lathe tool in the direction of the tool head, at least two coolant outlet lines branching off from contact points where the respective coolant outlet lines meet the coolant channel, in the area of the tool head, at least two of the coolant outlet lines arranged at positions offset in an axial longitudinal direction of the coolant channel.
A lathe tool for machining workpieces, said tool comprising a base body having a clamping section and a tool head which comprises a cutting region having at least one cutting edge, the tool head comprising at least one coolant channel for supplying a cooling and/or lubricating fluid to the cutting region, the coolant channel having in at least one tapered section, a cross-section tapering in the direction of the tool head and at least four coolant outlet lines branching off from contact points where the respective coolant outlet lines meet the coolant channel, in the area of the tool head, at least four of the coolant outlet lines arranged at positions offset in an axial longitudinal direction of the coolant channel, the contact points where the respective coolant outlet lines meet the coolant channel arranged in a spiral pattern around at least one portion of the at least one tapered section of the coolant channel.
