Disclosed is a wheel front burr removing device, comprising an upper servo motor, a right support plate, a right slide plate, right guide rails, a right cylinder I, a right cylinder II, a right driven conical friction wheel, a rim burr cutter, a right workbench, a right shaft, a mandrel and the like. Rim burrs are removed on the right station while cap section burrs are removed on the left station, double stations are adopted for machining, so the efficiency is very high.

A machining unit for machining, in particular turning and/or milling, workpieces, in particular elongate workpieces, in particular shafts, includes a machining tool. The machining tool can be moved along at least two different, in particular combined, motion paths in a motion plane. The machining until also includes at least one drive unit, which is designed for moving the machining tool along a first motion path and along a second motion path, which is different from the first motion path, possibly in a combined manner.

A selecting device causes a machine tool, which machines a workpiece from a bar material, to select another workpiece that the machine tool can machine from a leftover material, which is a remaining part of the bar material being machined, when a workpiece to be machined is not machinable from the leftover material. The selecting device includes: a selecting unit that refers to mountable tool data indicating a tool that can be mounted on a mount position of the machine tool, and causes the machine tool to select another workpiece that is machinable by the tool that can be mounted on the machine tool, in selecting another workpiece to be machined by the machine tool from the leftover material.

A machine tool includes a bed, and a table that is provided on the bed and movable in a Z-axis direction. The table includes a workpiece holder, a table base including a first support portion and a second support portion for turnably supporting the workpiece holder at positions spaced from each other in an X-axis direction, the workpiece holder being mounted on the table base, and a turning device that is provided in the first support portion, and turns the workpiece holder around a turning center axis extending in the X-axis direction. The machine tool further includes a first feeding device and a second feeding device that are provided on the bed and are connected to the first support portion and the second support portion respectively to drive the table in the Z-axis direction.

A handheld machining device (1), particularly for drilling, having a mechanism includes: a first mounting (20), on which a tool holder (2), and a motor (3, 4) arranged to rotate the tool holder (2), are mounted; a second mounting (30); and an element (40) for translatably guiding, between the first mounting (20) and the second mounting (30), a linear actuator (5) enabling the first mounting (20) to be spaced apart from the second mounting (30), and the first mounting (20) to be brought toward the second mounting (30). The motor (3, 4) is electric, and the rotor (4) of the first motor (3, 4) is directly mounted onto the tool holder (2) and is rigidly connected thereto.
