A machine tool for the machining of elongate workpieces comprises a workpiece support column (1) having workpiece support means (1001, 1003) for supporting a first workpiece (W1) and second workpiece support means (1002, 1004) for supporting a second workpiece (W2), the first workpiece support means (1001, 1003) and the second workpiece support means (1002, 1004) being arranged for supporting the first workpiece (W1) vertically above the second workpiece (W2). The workpiece support column (1) is rotatable around a vertical axis (C) so as to shift the workpieces between the machining station (B) and a station (A) for loading and unloading of workpieces. The workpiece support means comprise drive means (100) for applying torque to the workpieces for machining of the workpieces by turning. A motor and chuck assembly and a method of machining workpieces are likewise disclosed.

An apparatus reconfigures or configures a wheel associated with a train. The apparatus comprises a tool configured to engage the wheel a compound slide system for positioning the cutting tool in at least two axes. The compound slide system is controlled so that the wheel is configured in accordance with a profile. The slide system can be moved mechanically and / or pneumatically and / or can use a mechanical profile. The apparatus can have a low profile and a low weight.

A machine tool includes a bed that includes a guide unit, a first structure and a second structure that are each mounted over the bed, a first drive unit that moves the first structure along the guide unit, and a protector that covers at least part of the first drive unit. The protector is extendable and retractable with movement of the first structure, at least one of the first structure and the second structure includes a protector housing portion that houses at least part of the protector, and the protector housing portion is a space that is provided in a base portion of at least one of the first structure and the second structure and opened in a movement direction of the first structure. Accordingly, structures such as a headstock and a tool post can easily approach each other and the convenience of machining a workpiece by a machine tool can be increased.

Centering apparatuses and methods for precision placement of a product or component, such as a ceramic honeycomb body, prior to a post-production processing steps are provided. In particular, after extrusion of a component or ware, the component or ware oftentimes requires one or more post-production processing steps in order to obtain a final product. The centering apparatuses and methods described herein provide for the precise and accurate centering of the product (or component) prior to performing these post-production processing steps, thereby obtaining repeatable, consistent, high-quality final products.

A motor and chuck assembly for the machining of workpieces by turning comprises a stator (101), a rotor (102) placed radially inside the stator, a hollow workpiece-spindle (103) with a first end (103a) and a second end (103b), and a retractable jaw chuck (11) comprising jaws (11a) for clamping a workpiece. The workpiece-spindle (103) is surrounded by the rotor (102) at a position between the first end (103a) and the second end (103b). The workpiece-spindle (103) is rotationally fixed to the rotor (102). The workpiece-spindle (103) has a first inner diameter (d1) at the first end (103a) and a second inner diameter (d2) at the second end (103b). The rotor (102) has a third inner diameter (d3). The second inner diameter (d2) is substantially larger than the first inner diameter (d1) and / or than the third inner diameter (d3). Also disclosed is a method of machining workpieces.
