A linear transport system can have a carriage guide rail having a first and a second carriage, which are arranged in such a way that they can be moved independently of one another on the carriage guide. The XY table for this linear transport system can comprise a carrying structure and a first and a second linear guide, which are embodied with an angular offset relative to one another and each have a first and a second guide element, e.g., which can be moved relative to one another along a linear track. In one arrangement, the first guide elements of the first and second linear guides are connected to the carrying structure. The second guide element of the second linear guide can be connected to the first carriage and the second guide element of the second linear guide can be connected to the second carriage.

A manufacturing system including a base and multiple work machine modules that are arranged in an arrangement direction on base to be attachable to and detachable from base, in which one wheel of a pair provided on work machine module is engaged with one rail of a pair provided on base in a state in which positional deviation in the arrangement direction is prohibited, and the other wheel of the pair is engaged with the other rail of the pair in a state in which positional deviation is permitted in the arrangement direction, thereby the position of work machine modules on the base in the arrangement direction is specified, and work machine modules are fixed at a setting position on the base to be restricted so as to be drawn toward the base by a module fixing mechanism that is provided on the base.

A sliding linear motion guide device that is to be provided between a supporting body and a movable body is provided with: a rail (300) having a first guiding surface (302) and second guiding surfaces (304, 306) which are inclined; a carriage (200) having a receiving recess for receiving at least part of the rail and having a first sliding surface (204) facing the first guiding surface of the rail and second sliding surfaces (206, 208) facing the respective second guiding surfaces; and sliding members (10) each of which is a thin plate attached to one of the sliding surfaces. The sliding members each have a lubricant pocket (14) which is a recess surrounded by a land part (12).

Methods and systems for supporting and/or positioning mechanical components or tools, the methods and system employing work stands that have a moveable base, a vertical support member disposed on the moveable base, a support platform attached to an upper end of the vertical support member via a support coupling that permits independent rotational movement of the support platform, a plurality of extendable arms that are each pivotally coupled at a lower end to the vertical support member and pivotally coupled at an upper end to the support platform, and each extendable arm can be independently and controllably extended and retracted. The work stands further include a controller for controllably extending and retracting the extendable arms to position the support platform in a desired orientation, and a user input coupled to the controller and configured so that a user employing the controller can position the support platform in the desired orientation.

A cutting tool for boring (40) that is attached to a machining apparatus and used for cutting a hole (13) on a large-diameter side of a stepped hole of a workpiece (10) is provided. The cutting tool for boring (40) is a set of two tools, and each cutting tool for boring (40a, 40b) in the set of two includes a shaft part (41), a cutting blade (42) laterally protruding from the respective shaft parts (41), and an abutment surface (43) formed at the tip of each shaft part (41) and used to cause the tips of the respective shaft parts (41) to butt against each other. Each cutting tool for boring (40a, 40b) performs cutting while the two cutting tools for boring (40a, 40b) rotate integrally around the center line of the shaft parts (41) in a coupled state in which the tips of the cutting tools for boring (40a, 40b) are butted together.

The machine spindle arrangement (22) according to the invention forms a unit with a motor (19) as central element. At one side of the motor (19) a spindle neck (35) with a spindle (32) is flanged that is directly driven by the rotor (28) of the motor (19). The spindle (32) is a so-called null spindle that can be replaced without readjustment with all bearings and other wear parts due to the present exactly adjusted positioning surface (39) that abuts against an axially properly defined bearing contact surface (38). At the backside of the motor (19) facing away from the spindle (32), a tool releasing device (20) and an angle adjustment transmission (21) is arranged that serves to rotate a present traverse feed shaft (42) relative to the spindle (32). The traverse feed shaft (42) serves to actuate an adjustment device at the tool (15).
