A cutting machining apparatus includes a rectangular box-shaped housing as a whole, a base member fixed to the housing via a cushioning member, a workpiece holder disposed inside the housing to be apart from the housing, fixed to the base member, and holding a workpiece, and a machining unit disposed inside the housing to be apart from the housing, fixed to the base member, and machining the workpiece.

A power tool includes a housing, a motor positioned substantially within the housing, a drive mechanism supported by the housing and coupled to the motor, a battery pack electrically coupled to the motor, and an isolation system. The isolation system includes an interface member positioned substantially within the housing. The interface member receives a portion of the battery pack to electrically couple the battery pack to the motor. The isolation system also includes a plurality of isolators coupled between the housing and the interface member to isolate the battery pack from the housing during operation of the power tool.

A machine tool having a workpiece spindle, a tool spindle, and at least one movable machine axis configured to execute a machine kinematic to machine the workpiece using the tool.

The machine tool has a structure to be damped, and a device for vibration damping connected to the structure for vibration damping of the structure to be damped, the device having a spring system with at least one spring element and a mass system with at least one mass element. wherein

The structure to be damped has a first eigenmode in a first direction, the structure to be damped has a second eigenmode in a second direction different from the first direction, and the spring system has first and second rigidity in first and second directions of action, respectively, with the first rigidity being greater or less than the second rigidity.

A machine tool system includes a machine tool including a processor to process a workpiece with a tool, and a bed on which the processor is mounted, a transport apparatus including two, left and right, legs spaced apart from the bed to transport the workpiece and feed the workpiece to the processor or discharge the workpiece from the processor, and a plate that connects the bed to the legs and is elastically deformable. The plate is upright such that a plate surface is aligned with a front-rear direction, and a connection portion of the plate that connects with the bed and a connection portion of the plate that connects with the legs are displaced in a front-back direction.

A guide apparatus includes a track member, a movable member having a first rolling surface that forms a load rolling passage together with a rolling surface of the track member, and a damper provided on a first surface. The first surface is at least a portion of the surface of the movable member opposed to the track member excluding the first rolling surface. The damper includes a plate member disposed in such a way as to cover the first area and a reservoir space formed between one surface of the plate member and the first area. The reservoir space contains a damping medium and allows the plate member to displace relative to the first area. The damper is provided on the movable member in such a way that the other surface of the plate member slides on at least a portion of the surface of the track member opposed to the movable member.

A machine tool that machines a workpiece by a tool includes a workpiece spindle device that holds the workpiece in a rotatable manner with a predefined workpiece rotational axis Rw as a center, one or more in-machine robots, and a connecting mechanism that attaches the one or more robots on the machine tool so that the one or more robots move independently from the workpiece, with the workpiece rotational axis Rw serving as a center.

A machine tool that cuts a workpiece by a rotary tool includes a tool spindle device that holds the rotary tool in a manner to allow self-rotation with a predefined tool rotational axis Rt as a center, one or more in-machine robots, and a connecting mechanism that attaches the in-machine robot on the tool spindle device so that the in-machine robot moves independently from the rotary tool at a periphery of the tool spindle device with the tool rotational axis Rt as a center.

A cutter holder has a body, a fastening bolt, and a vibration absorbing structure. The body has a specific weight. The fastening bolt is mounted inside the body. The vibration absorbing structure is mounted inside the body and has a sleeve, an elastic unit, a spacer, and a set nut. The sleeve is mounted around the fastening bolt and has a specific weight. The specific weight of the sleeve is larger than the specific weight of the body. The elastic unit is mounted around the fastening bolt and has two opposite ends. One of the ends of the elastic unit abuts against the sleeve. The spacer is mounted around the fastening bolt and abuts against the other end of the elastic unit. The set nut is screwed with the fastening bolt and abuts against the spacer.

Fixture Apparatus and methods of manufacturing fixture apparatus. Fixture apparatus comprising: a first body to at least partially support an object, the first body including a structure having variable stiffness along at least a first axis of the first body.

A damping apparatus includes a damping unit 30 composed of a plurality of damping plates 36 having plasticity, a holding member 31 holding at least one ends of the damping plates 36 in a manner to allow deflection of the damping plates 36 with the damping plates 36 laminated together, and a contact member 33 provided at a position spaced from a holding position of the holding member 31, and attached to an outermost one of the damping plates 36, or extending through and held by the damping plates 36 in such a manner that it can be brought into contact with the outermost one of the damping plates 36 and can be moved in an extending direction thereof. The damping unit 30 is supported by a support mechanism 2 in such a manner that the contact member 33 can be brought into contact with an object W.
