A lathe includes a spindle, an opposite spindle, a tool post, a controller, and a contact-type breakage detector. The controller determines whether the cut-off tool is broken according to a control parameter for controlling at least one of the spindle and the opposite spindle at a first detection timing immediately after the cut-off tool cuts off the bar material while the opposite spindle holds the bar material held by the spindle. The controller determines whether the cut-off tool is broken according to a detection result by the contact-type breakage detector at a second detection timing different from the first detection timing.

A system for machining and positioning an automobile hub and a production line for intelligent cleaning and precision including upper and lower mounting plates connected vertically. At least three U-shaped blocks are fixed on a top surface of the upper plate. An L-shaped support is mounted between every two blocks including a screw-equipped ball head disposed thereon. The support is driven by a first driving apparatus to move along the upper mounting plate. A slidable chuck is disposed in each block, with a push rod assembly connected to the bottom. The assembly is driven by a second driving apparatus to move along the upper mounting plate with the chuck. Three wedges are circumferentially fixed on a top surface of the lower plate and are driven by a third driving apparatus to move along the lower plate. Inclined surfaces of the wedges are mated with bottoms of the push rod assemblies.

The invention relates to a cutting tool apparatus comprising a tool head rotatingly drivable about an axis of rotation, which tool head has a tool slide adjustable along an adjustment axis and an electrical measuring device for detecting an adjustment path of the tool slide, and comprising an external display device which is mechanically and electrically releasably connectable to the tool head and has a display unit for displaying the adjustment path of the tool slide. In order to further develop the cutting tool apparatus such that its handling is simplified, it is proposed according to the invention that the display device is mechanically securable on the stationary tool head in order to set the tool slide and is automatically releasable from the tool head if a predeterminable rotational acceleration of the tool head is exceeded.

A method for manufacturing a roll mold by cutting a roll, includes generating a control waveform based on a signal corresponding to a rotary position of the roll, and making a plurality of cuts on a surface of the roll by, while the roll is rotated, reciprocating a cutting blade in a radial direction of the roll in accordance with the control waveform. Making the plurality of cuts includes at each of a plurality of predetermined locations, making a predetermined number of cuts of predetermined depth based on the control waveform. Generating the control waveform includes generating a control waveform dictating that, when multiple cuts are made at a predetermined location, each subsequent cut will have a smaller depth than a preceding cut.

A clamp for a robotic drill and related method and system for robotic drilling of a component. The clamp attaches to a drilling tool of a robotic drill. The clamp includes: an attachment portion configured for attachment to the drilling tool; a frame linearly moveable relative to the attachment portion along a central axis of the clamp parallel to a drilling direction of the drilling tool; an actuation mechanism including a servo motor configured to drive linear movement of the frame relative to the drilling tool; a workpiece contacting portion at a distal end of the frame, including a surface for contacting a surface of a workpiece to be drilled and an aperture allowing for passage of a drill bit of the drilling tool through to the workpiece surface; and a force sensor arranged to measure a force acting on the workpiece contacting portion in the drilling direction.

A cutting tool mounting assembly includes a base that defines a receptacle. A bushing is configured to be received in the receptacle and includes an aperture. A rotatable cutting tool is received in the aperture of the bushing. The rotatable cutting tool includes a cutting tip. The cutting tool mounting assembly includes a split, modular and wireless wear detection system including a target proximate the cutting tip for emitting a signal representative of the wear of the cutting tip, a sensor element for detecting the signal emitted by the target at a spaced apart location with respect to the target, a data recording and data transmitting device for recording data from the sensor element and for wirelessly communicating the data to a processor and/or a display device.

A rail drill drive train can include a common drive end between a single drive motor and a common gear. A speed train end can extend from the common gear to rotate the drill spindle. A feed train end can independently extend from the common gear to advance and retract the drill spindle. The speed train end can include a sprag gear so that, without unmeshing any gears, the drill spindle is not unnecessarily rotated in the reverse direction when the drive motor is reversed to retract the drill spindle. A rail drill control circuit and related sensors can enable automatic operation throughout the complete drilling cycle without any manual input from the user other than starting the cycle. Such a fully automatic drilling cycle can minimize overall cycle time to preserve battery life and can free the user to perform other tasks between drill moving and clamping operations.

A method for assisting with the positioning of a drill bit for boring a component, which includes capturing images of a first component which has notable points, of calculating a digital representation from these images, of superposing the digital representation thus calculated and a digital design representation of the component, of evaluating the distances of the centers of bores to be created with respect to the notable points, and of positioning a drill bit with the aid of a camera and of the evaluated distances. The method continues in the same way for the other components to be assembled.
