Three systems for the destruction of the data storage portion of electronic media storage devices such as hard disk drives, solid state drives and hybrid hard drives. One system utilizes a mill cutter with which the hard drive has relative motion in the direction of the axis of the mill cutter to destroy the data storage portion. A second system utilizes a laser to physically destroy the data storage portion. The third system utilizes a chemical solvent to chemically destroy the data storage portion.

A machine tool chip removal device including a coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed. The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed.

A part cleaning machine includes a cradle moveable along an X axis, and rotatable about a first cradle axis. A part holder is attached to the cradle, and is rotatable about a second cradle axis. A chuck holder is moveable on a tool positioning plane that is perpendicular to the X axis. A tool chuck is attached to and moveable with the chuck holder. A tool holder is moveable relative to the chuck holder along the X axis. A plurality of tools are releasably attached to the tool holder for selective attachment to the tool chuck. A machine controller is operable to control movement of the chuck holder, the tool chuck, and the tool holder to transfer a selected one of the tools between the tool chuck and the tool holder, and position an appropriate tool and the part in different positions for several different cleaning operations.

A method for cutting machining of turbine blades (1) on a multi-axis machine tool, the turbine blade (1) is held by a rotatable blade-root clamping device and a rotatable blade-tip clamping device (2) and is machined by means of a tool which is chucked in a tool spindle. A first profile section (4) which is adjacent to the blade tip is first of all machined by the tool and the tool is then removed. The tool spindle then grabs an already horizontal additional clamping device (5) which has clamping jaws (6.1, 6.2) adapted to the first profile section (4). The additional clamping device (5) is positioned on the blade-tip clamping device (2) in such a way that the clamping jaws (6.1, 6.2) rest in the first profile section (4). The tool spindle then grabs a tool and machines the remaining profile section with it.

A machine tool can perform a turning process using a fixed tool and a milling process using a rotating tool. The machine tool includes: a tool spindle having an air supply portion, for rotating the rotating tool; a lower tool rest for mounting a plurality of fixed tools thereon; a tool holder having a tapered surface restraining a tool, and attached to the lower tool rest, for detachably holding the tool; an automatic tool changer; and a special tool mounted on the tool spindle, into which the air is introduced from the air supply portion. When the tool is automatically changed by the automatic tool changer, the special tool mounted on the tool spindle is coupled to the tool holder, and the air from the air supply portion is supplied to the tapered surface through the special tool.

An interchangeable unit adapted to couple to a computer numerical control (CNC) machine is disclosed comprising a holder that couples to a spindle of the CNC machine, a controller, wherein said controller is configured to receive the rotational speed of the spindle as an input, and a material processing unit, wherein said material processing unit executes a first function in response to a first rotational speed range of the spindle and executes a second function in response to a second rotational speed range of the spindle.

A rotary part of a pump (200) is connected to a body member (110) to be rotatable together. When the body member is attached to a main shaft (20) of a machine tool (10), a rotation stopping pin (310) of a rotation stopping device (300) fits in a fitting hole (41) of the machine tool and abuts on a wall surface (41a) of the fitting hole, whereby the rotation stopping pin and a rotation stopping lever (340) axially move against an elastic force of a spring (320) and the rotation stopping lever disengages from an engagement hole (113) in the body member such that the body member becomes rotatable relative to a support part (150, 160) that rotatably holds the rotary part. A force detecting sensor (50) outputs a force detection signal indicating a force with which the rotation stopping pin is pressing against the wall surface.

A harsh environment camera system. The system can include an enclosure having an electronics compartment and a camera compartment with a camera opening. A camera module is disposed within the camera compartment and one or more electronic components capable of generating heat are positioned in the electronics compartment. A compressed gas connector, connectable to a gas source, can be mounted on the enclosure. A metering orifice having an inlet and an outlet is in fluid communication with the connector. The metering orifice is operative to cool a gas flowing therethrough, thereby condensing moisture from the gas. A gas conduit is in fluid communication with the outlet of the orifice and extends through the electronics compartment to the camera compartment. A portion of the gas conduit is positioned in close proximity to the one or more electronic components, whereby the gas is heated prior to entering the camera compartment.
