A method for machining a workpiece and a lathe are provided, as well a tool head (1) for a lathe (2), having a tool holder (5) retaining a machining tool (3), wherein the tool head (1) has at least one actuator (6) for generating an additional movement of the tool holder (5) in the form of an oscillating pivoting movement about at least one pivot axis (7)

A composite sheet that includes a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The first sheet is a nonwoven material that has discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the first sheet to their distal ends and wide base openings adjacent to the second surface of the first sheet. The second sheet is a generally planar sheet that contacts the distal ends of the protrusions on the first sheet. The second sheet is bonded to the first sheet at spaced apart inter-sheet bond locations where the first region of the first sheet contacts the second sheet.

A brake rotor includes an outer surface; first and second opposing braking surfaces, each bounded by the outer surface to form first and second opposing braking surface edges. A plurality of concentric grooves are formed on the first and/or second braking surfaces.

A method for machining a wheel hub assembly for a vehicle includes providing a radially outer ring having a first radial flange, a radially inner hub having a second radial flange facing the first flange, and a plurality of rolling elements disposed between and rotatably coupling the outer ring and the hub. The hub is rotated simultaneously and asynchronously about the outer ring while machining a front surface of the second flange, which faces away from the first flange, and while rotating the outer ring about an axis of rotation of the wheel hub assembly, so as to form a machined surface of the second flange. The machined surface of the second flange is perpendicular to the axis of rotation and parallel to a front face of the first flange opposite to the front face of the second flange.

An object of the present invention is to provide a skin material excellent in tactile sensation.

The present invention provides a skin material having at least a topcoat layer, wherein an arithmetic mean roughness Ra of a surface of the topcoat layer is 12 m or less, an average spacing S of convex portions of the surface of the topcoat layer is 250 to 450 m, and the topcoat layer contains resin beads with an average particle size of 5 to 20 m.

An automated station (1) for the finishing of brake pads (4) comprises at least one rotary finishing tool (2) for finishing a friction layer (22) of the brake pad (4), a workhead (3) to pick, retain and release the brake pad (4), a handling unit (6) to move the workhead (3) along a programmable path comprising a pass over the rotary finishing tool (2) and a guide (5) having a mouth (27) which is passed through by the workhead (3) in order to start the finishing pass along the length of the programmable route, the guide (5) contacting the workhead (3) to define, along at least one direction (A; C), the relative position between the workhead (3) and the brake pad (4) during the finishing carried out by the rotary finishing tool (2).

A cutting insert and an indexable insert-type cutting tool includes a cutting edge (6A) formed on each of a pair of side ridge portions of at least one of the side faces, wherein an insert main body (1) is formed in the shape of having front-back inversion symmetry which is 180 rotationally symmetrical with respect to a line of symmetry (N) passing through the center of the side faces; a flank face adjacent to the cutting edge (6A) is formed on the side face in the vicinity of each of the pair of polygonal faces (2); each of the flank faces is formed in the shape of a twisted face; the pair of side ridge portions on which the cutting edge (6A) is formed intersect each other in such a manner that the second corner portion (B) of one side ridge portion protrudes outside the other side ridge portion.

Sample application systems can include an extraction mechanism to remove a sample from sample containers, a sample vessel disposed on a deployment mechanism, where the deployment mechanism is arranged to move the sample vessel to receive a sample, an extraction mechanism washing station to wash the extraction mechanism, a sample applicator to remove a portion of the sample in the sample vessel and apply it onto a sample carrier, where the deployment mechanism can move the sample vessel to a sample application position, a sample vessel washing station to wash the sample vessel, where the deployment mechanism can move the sample vessel to the sample vessel washing station, a sample applicator washing station to wash the sample applicator after the sample has been dispensed onto the sample carrier, and a fluid control system to control flow of a fluid provided to the extraction mechanism and the sample applicator.
