A machine tool comprising: a first body; a first leg, a second leg, and a third leg coupled to the first body via first joints and configured to support at least the first body; a second body including a tool holder; a fourth leg, a fifth leg, and a sixth leg coupled to the second body via second joints and configured to support at least the second body; and a first actuator coupled to the first body and to the second body, the first actuator being configured to cause rotational motion between the first body and the second body to enable a change in walking direction of the machine tool and/or to enable a change in machining stiffness and a change in work volume of the machine tool.

A valve seat processing machine (1) configured to process a valve seat (118) in a valve device (101) including a valve body portion (110) which forms a flow passage of fluid and a valve drive portion (120) which drives a valve element (124) capable of tightly engaging with the valve seat (118) in the valve body portion (110) includes: a base portion (10) attached to the valve body portion (110); a main body portion (20) movable relative to the base portion (10) in two different axial directions; a support portion (30) movable relative to the main body portion (20) in a drive direction of the valve element (124); a main spindle (40) rotatable relative to the support portion (30) about an axis parallel to the drive direction of the valve element (124); and a tool holder (50) configured to hold a tool (T) for processing the valve seat (118).

A machine tool for carrying out operations on a part includes a longitudinal rail, a transverse arm, a module for connection between the transverse arm and the longitudinal rail, the module being fitted in translation on the longitudinal rail, a tool which is supported by the transverse arm, and a retention unit which is arranged at one end of the transverse arm, and includes at least one sucker. The machine tool has an assembly configurationin which the retention unit and the tool are positioned respectively on both sides of the longitudinal rail, such that the tool is fitted cantilevered relative to the longitudinal rail. This provides the machine tool with great polyvalence, in that it makes it possible to carry out operations in areas which in particular have significant curvatures, which are difficult to access, or which are unsuitable for securing of the sucker(s) of the retention unit.

A motorized apparatus for use in maintaining a turbine assembly includes a body configured to move through the turbine assembly. The motorized apparatus also includes at least one maintenance device coupled to the body. The motorized apparatus further includes a drive system configured to move the body relative to the turbine assembly. The drive system includes a motor and a steering component. The steering component is configured to steer the motorized apparatus relative to the turbine assembly.

A pilot pin assembly is slidably receivable within a tool bit of a drill press. The pilot pin assembly includes a first pin defining an interior cavity, and a second pin at least partially received within the interior cavity of the first pin. A spring is positioned within the interior cavity for biasing the second pin toward an extended position relative to the first pin.

A magnet sensing portable autonomous device includes a platform. A plurality of wheel sets is coupled to the platform. A drive system is used for driving the plurality of wheels. An attachment mechanism is positioned on an underside of the platform for securing the device to a surface. A control board is used for controlling the operation of the device. In some embodiments, a drill spindle assembly is coupled to the platform. A drill feed assembly is coupled to the drill spindle assembly for raising and lowering the drill spindle assembly. A plurality of sensors are operable to sense one or more magnets disposed below the surface. A drive table is used for positioning the drill spindle assembly in an XY plane based on an output of said plurality of sensors.

A sale mode cross slide system having a cross slide with a hack plate, a front plate and a saddle. The back plate can have a pair of end caps, a pair of linear guides, a first ball screw, a first gear box, a first servo motor, a first drive, and a first manual feed knob and the front plate can have a pair of end caps, a pair of linear guides, a second ball screw, a second gear box, a second servo motor, a second drive, and a second manual feed knob. The system can have a power supply, a communications hub with a processor and data storage.

A weld cutting machine having a first cutting jaw part (4) and a second cutting jaw part (5), a base frame (500) having fixedly attached thereto the second cutting jaw part (5), a power unit and a transmission mechanism (3). The power unit is connected to the transmission mechanism (3) to arrange for movement of at least one of the first cutting jaw part or the second cutting jaw part (4, 5).

A system for repairing dovetail slots includes a slot adaptor having a body configured and disposed to nest between first and second side walls of a dovetail slot, and a tool holder configured to be coupled with the slot adaptor. The tool holder includes a tool guidance system configured and disposed to direct a tool into contact with one of the first and second side walls of the dovetail slot. A cutting tool is mounted in the tool holder. The cutting tool includes a tapered surface configured and disposed to form a tapered recess in the one of the first and second side walls of the dovetail slot.
