A machine tool which causes a tool mounted on a main spindle and workpiece attached to a table to move relative to each other so as to machine the workpiece, said machine tool being equipped with: a column that has guides for guiding movements in the vertical direction, that is, the direction of gravity; and a moving body that supports a spindle head at the front and moves in the vertical direction along the guides. The guides comprise a pair of right and left first guides and at least one second guide that is provided on the inner side of and posterior to the pair of first guides.

The present invention relates to a machine tool for machining a workpiece. The machine tool has a motor spindle for the rotative actuation of a tool. The motor spindle is supported by a stand. A turning bearing is provided at the stand and the motor spindle at the turning bearing is pivotable and positionable about a first turning axis. At the motor spindle, a linear guide is provided, which enables an advancing movement of the tool parallel to the spindle axis.

A grinding machine for grinding of a profile, comprising a machine bed, wherein a machining device is arranged on the machine bed, wherein the machining device comprises a swivel head which carries a first grinding spindle with a first grinding tool, especially with a roughing grinding tool, and a second grinding spindle with a second grinding tool, especially with a finishing grinding tool, wherein a workpiece carrier being a rotary table is arranged on the machine bed. To allow the production of workpieces with a complex geometry in a high precision in an economical manner the invention proposes that the swivel head further carries at least one third grinding spindle with a third grinding tool, wherein the swivel axle of the swivel head is directed horizontally and the axis of rotation of the rotary table is directed vertically.

In the context of multi-axis motion control systems, a modular frame is disclosed comprising two or more subassemblies that each comprise one or more motion actuators. Each subassembly comprises a reference interface surface along which the subassembly may be attached to that of an adjoining subassembly. Motion actuators of a first subassembly are aligned to a first reference interface surface so that motion vectors of the actuators come into precise alignment with the motion vectors of actuators on a second subassembly when the first subassembly and second subassembly are joined. In forming an additive manufacturing system, a material depositing component may be attached to the first subassembly and tested as a unit with the first subassembly before the second subassembly is made or becomes attached to the first subassembly.

A machine tool comprises a frame, which carries a fixed gantry for supporting at least one tool spindle. The gantry comprises a gantry recess, through which a working space is accessible. The one or more tool spindles on the gantry can each be moved vertically in a first direction and in a second direction orthogonal to the first direction. The machine tool further comprises a workpiece table with at least one location for supporting workpieces. The workpiece table is movable in translation in a third direction Y orthogonal to the first direction and the second direction. At least one tool magazine is associated with the at least one tool spindle tool spindle. Tools for tool changing can be fed through at least one magazine opening in the gantry. Tool changing between the one or more tool spindles and the at least one tool magazine takes place in a pick-up process.

The invention relates to a machine for processing plastic workpieces. A machine housing surrounds a working chamber located between a workpiece spindle for rotationally driving the workpieces about a workpiece axis of rotation and a fast tool servo for producing an oscillating feeding movement of a rotary tool in the direction of the workpieces. The workpiece spindle is provided with a carriage which can be driven and is guided on at least two guide surfaces of a guiding arrangement in order to produce a relative advancing movement between the workpiece and the rotary tool. The advancing movement runs transversely with respect to the feeding movement and defining therewith a processing plane in which during processing the rotary tool engages with the workpiece. The guiding arrangement is mounted on the machine housing such that the processing plane extends between the two guide surfaces.

A machine tool, in particular a multi-spindle and/or double-spindle milling machine, comprising a machine frame, a workpiece clamping device for clamping a workpiece, an axis slide assembly which is arranged on the machine frame and is configured to linearly move the workpiece clamped on the workpiece clamping device by way of two controllable linear axes in a Y-direction and a Z-direction, and a spindle carrier assembly, which is arranged on the machine frame and has at least two tool-carrying work spindles that can be moved independently of each other in the S1- and S2-directions which are each inclined with respect to the Y-direction and Z-direction and to one another.

Disclosed is a five axis machining apparatus. The five axis machining apparatus comprises a base member, a support member, a stationary base, a first moving plate, a second moving plate, a third moving plate, a fourth moving frame, a fifth moving frame and a controller (not shown). The five axis machining apparatus is designed to hold together A, C and X axes thereby resulting in a reduced size without compromising on rigidity that is required for processing metallic job components. The five axis machining apparatus allows independent as well as simultaneous control of X, Y, Z, A and C axes.

A precision protection jig with a base is provided and includes: a platform having its two ends provided with a first end portion and a second end portion, respectively, wherein a table connects bottoms of the first and second end portions, and a connection block is appropriately positioned on inner wall surfaces of the first and second end portions; a horizontal support jig having two ends provided with two connection plates, respectively, such that the connection plates allow the horizontal support jig to be transversely connected to the connection block of the first and second end portions, respectively; and a vertical support jig having two ends connected to the horizontal support jig and the table centrally and perpendicularly, respectively, wherein the horizontal support jig exerts lateral stress upon the first and second end portions, whereas the vertical support jig produces vertical stress.

A machine tool and a feed saddle structure thereof are provided. The feed saddle structure includes: a fixed column having a first vertical side and a horizontal side adjacent to the first vertical side; a feed saddle having a second vertical side corresponding in position to the first vertical side of the fixed column, and a bottom portion being adjacent to the second vertical side and corresponding in position to the horizontal side of the fixed column; a first guide rail and a second guide rail disposed on the first vertical side and the horizontal side of the fixed column, respectively; and a first slider and a second slider disposed on the second vertical side and the bottom portion of the feed saddle, respectively, and engaged with the first guide rail and the second guide rail, respectively, thereby increasing the dynamic and static rigidity of the machine tool.
