Abstract:
A machine tool with lathe tool and milling cutter includes a machine support, a worktable, a moving device, a lathe feeding mechanism and a milling feeding mechanism. The worktable is positioned on the machine support. The moving device is slidably assembled to the machine support along a first direction and located above the worktable. The lathe feeding mechanism and the milling feeding mechanism are slidably assembled to the moving device along a second direction perpendicular to the first direction. The lathe feeding mechanism includes a feeding assembly and a lathe tool connected to the feeding assembly. The feeding assembly is configured for driving the lathe tool to move along a third direction substantially perpendicular to the first and second direction reciprocally, the milling feeding mechanism includes a milling cutter and is configured for driving the milling cutter to move along the third direction.
Abstract:
There is disclosed a readjustment system comprising an advancing head supporting a cutting edge and being retained on a spindle. The cutting edge is advanced by means of an actuation element adjustable by a contactless linear drive.
Abstract:
An example method includes performing a machining operation by providing linear movement of a tool along a feed axis relative to a workpiece while superimposing oscillation of the tool onto the feed axis and providing rotation of the tool relative to the workpiece. During an optimization mode, the machining operation is performed on a first workpiece portion while providing the linear movement at an initial feed velocity, and sequentially superimposing the oscillating at a plurality of different frequencies. An optimal oscillation frequency is determined from the plurality of different frequencies which causes the tool to apply less force to the first workpiece portion at the initial feed velocity than others of the frequencies. During a run mode, the machining operation is performed on a second workpiece portion having a same composition as the first workpiece portion while superimposing the oscillation at the optimal oscillation frequency.
Abstract:
A linear actuator having a linearly extending slider disposed in a body casing, a plurality of magnets fixed to the slider along the axial direction of the slider, and a plurality of coils supported by the body casing so as to surround the slider to which the magnets are fixed, the linear actuator being structured so that a slider shifts in the axial direction relative to the body casing due to interaction between energized coils and magnets, the linear actuator further comprising a plurality of flat springs each supporting one end or the other end of the slider in the axial direction, each flat spring being elastically deformed relative to the axial direction of the slider.

Abstract:
A tool holder assembly and method for intentionally inducing modulation in a machining process. The tool holder assembly is configured for mounting in a tool block on a machining apparatus and includes a tool holder body configured to be secured to the tool block of the machining apparatus, a tool holder mounted on the tool holder body and configured for securing a cutting tool thereto, and a device for imposing a superimposed modulation on the tool holder so as to move the cutting tool relative to the tool holder body and thereby relative to the tool. The tool holder assembly is useful in a process for producing chips having a desired shape and size, and particularly to a method of controllably producing nanocrystalline chips.
Abstract:
A bar feeder for feeding a machine tool, comprising at least one guide that forms a channel along which the bar to be fed is made to advance by way of a bar pusher connected, through a bridge, to a carriage that is guided parallel to the channel and is actuated by a linear electric motor.

Abstract:
A collet chuck comprises a rotating cylinder block defining a cylindrical axis and an exterior cylindrical surface with first and second annular grooves. A collet and collet sleeve are at least partially surrounded by the rotating cylinder block. A piston slides within an annular interior space in the rotating cylinder block. A stationary port block has an interior cylindrical surface adjacent the exterior cylindrical surface of the rotating cylinder block and connects a first inlet port with a first annular groove and a second inlet port with the second annular groove. Switching pneumatic pressure between the first and second inlet ports moves the piston and collet sleeve between the clamping and unclamping positions and the gap between the rotating cylinder block and the stationary port block provides a frictionless seal.
