The present invention realizes the function of automatic loading and unloading, and improves the working efficiency and the consistency of workpiece processing.

The present invention discloses a five-axis vertical machining system with automatic loading and unloading, including a feeding mechanism, a loading mechanism, and a numerical control machine tool. The feeding mechanism is arranged in front of a ram assembly, and the feeding mechanism drives a raw material to move along an X axis and/or a Y axis of the numerical control machine tool; the loading mechanism is fixed on the ram assembly; and the loading mechanism moves along a Z axis of the numerical control machine tool to drive the raw material onto a cradle assembly of the numerical control machine tool. The present invention realizes an automatic loading and unloading function by setting a feeding mechanism capable of automatic feeding and a loading mechanism with automatic loading to cooperate with each other, thereby improving the working efficiency and saving manpower.

A machine tool includes a workpiece holder, a tool holder holding working tools that includes a hob cutter used in a rough machining and a skiving cutter used in a finish machining, a tool magazine, a tool replacing device replacing one of the working tools mounted on the tool holder with the other of working tools housed in the tool magazine, a rough machining controlling section performing the rough machining on the workpiece, a tool measuring device measuring a position of a blade in a rotation direction of the skiving cutter, an angle correcting section correcting a rotation angle of the skiving cutter based on a result measured by the tool measuring device, and placing a tooth space formed in the workpiece and an edge tip of the blade in a position corresponding to each other, and a finish machining controlling section by which workpiece is finish machined.

A spindle drive tool for adjusting a position of a head of a spindle relative to a piston of an electro-mechanical automatic lubrication system in which the spindle and piston are connected by complementary screw threads includes a mounting portion and a coupling portion connected to the mounting portion. The mounting portion includes a bearing surface having a spindle head inlet at a first end, a first cavity and a second cavity. The spindle head inlet opens into the first cavity, the first cavity has a cross section configured to couple with the spindle head such that the spindle head cannot rotate relative to the mounting portion while in the first cavity, and the second cavity is coaxially with the first cavity and has a larger cross section than the first cavity such that the spindle head can rotate freely in the second cavity.

A workpiece support system includes: a plurality of rods that are extendable and retractable in an axial direction; a holder rotatably placed in an upper end portion of each of the rods, to hold a workpiece; a first lock part that keeps an extended/retracted position of the rod in the axial direction; and a position adjustment device including a hand portion configured to hold the rod or the holder, to perform position control of the hand portion. The position adjustment device moves the hand portion, to extend and retract the rod, based on shape data of the workpiece that is recorded in advance, in a state where the rod or the holder is held by the hand portion, and the first lock part keeps the extended/retracted position of the rod extended and retracted by the position adjustment device.

A device is proposed for machining a workpiece using a robot which holds and moves the workpiece, in which the robot has a drive unit which is suitable for fixing the workpiece in a clamping device. According to the method the workpiece is placed in a clamping device by a robot and then machined after the workpiece has been fixed in the clamping device by means of the robot.

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.

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.
