摘要:
The invention relates to a machining device for producing a plasticizing cylinder (20, 20') with at least one conical screw-type bore. Said machining device comprises a clamping mechanism (12, 12', 14, 14') for mounting the plasticizing cylinder (20, 20') that is to be machined as well as a machining unit (40, 100) for machining the conical screw-type bore. According to the invention, the clamping mechanism (12, 12', 14, 14') is rotatably driven and is configured for eccentrically accommodating the plasticizing cylinder (20) that is to be machined such that the plasticizing cylinder (20) is made to gyrate in a wobbling manner about the axis of symmetry thereof when the clamping mechanism (12, 12', 14, 14') rotates, the future centerline of the conical bore forming the axis of rotation. The machining unit (40, 100) is provided with a turning chisel (46, 106) which can be linearly moved back and forth in the direction of the axis of rotation.

The invention relates to a stripping unit for machining plastic pipes or pipes which are coated with plastic and covered with a barrier layer or oxide layer, in particular in order to weld or adhesively bond two such pipes to one another, or for machining pipes having plastic fittings, sleeves or the like, in order to remove the barrier layer or oxide layer on the outer surface of the plastic pipe transversely or substantially transversely to the longitudinal axis thereof by orbital cutting prior to the welding process. The stripping unit substantially comprises a housing (2) with a threaded spindle (3) which projects out of, and is fixedly connected to, the housing (2), it being possible for a clamping mandrel (4), into which the threaded spindle (3) is screwed upon rotation with driving of the housing (2), to be screwed onto that end of the threaded spindle (3) which is remote from the housing (2), wherein an arm-shaped sliding block (5) is arranged in parallel with the threaded spindle (3) and is likewise held at one end in the housing (2) and bears, at the opposite free end thereof, a stripping blade (21) which projects into the region of that end of the clamping mandrel (4) which holds the threaded spindle (3). The sliding block (5) can be pivoted and locked by means of a lever mechanism, such that the stripping blade (21) can be moved into a predefinable position with respect to the clamping mandrel (4) and be releasably locked, in order to apply a defined or adjustable pressing force of the stripping blade (21) to a pipe (25) to be stripped.

The present invention relates to a machining system etc. capable of highly accurately machining a workpiece even in a case where the workpiece is deflected. A machining system 1 is configured with a lathe 10 having end portion supporting mechanisms 13, 15 for supporting both end portions of an elongated workpiece W horizontally, a tool rest 20 for holding a tool, a feed mechanism for moving the tool rest 20 in three orthogonal directions, and a control device 25 for controlling the feed mechanism, and a non-contact measuring device 30 for measuring the deflection shape of the workpiece W when the workpiece W is rotated. The control device 25 moves the tool along the deflection shape measured by the non-contact measuring device 30.

The present invention relates to a machine for machining crankshaft (5) ends, which comprises two machining heads (1, 2) designed to machine crankshaft (5) ends and two machining stations (3, 4) designed to receive and secure at least one crankshaft (5), said machining stations (3, 4) being disposed between the two machining heads (1, 2). The crankshafts (5) will be mounted in such a manner as to be disposed parallel to each other and oriented at 180º. Additionally, the machining heads (1, 2) are designed to be positioned facing the ends of the crankshafts (5) of the machining stations (3, 4). Additionally, the invention relates to a crankshaft (5) machining process based on the fact that both machining heads (1, 2) alternately machine flange ends (9) and spike ends (8) in the crankshafts (5) secured to the machining heads (3, 4). In this manner, the machine machines crankshafts without stopping between the machining of two successive crankshafts.

The milling cutter (10) comprises three blades (11) each having a cutting edge (12) and a rear face (14). The cutting edges extend radially outwards from a longitudinal axis (x) so as to create, during the rotation of the milling cutter, one or two concave surfaces (13) for receiving the ends of one or two electrodes (E). The rear face (14) has a concave profile in a section plane perpendicular to the cutting edge (12).

Die vorliegende Erfindung betrifft ein Verfahren und eine Maschine zur Herstellung eines Rotors einer Exzenterschneckenpumpe, bei der bzw. bei dem die Gestalt des Rotors durch einen Schälvorgang hergestellt wird, dem sich ein Glättvorgang der Oberfläche anschließt. Aufgabe der Erfindung ist es, den Glättvorgang mit diesem Verfahren bzw. mit dieser Maschine weniger zeitaufwendig und zudem kostengünstiger zu gestalten. Gelöst wird diese Aufgabe mit einem Verfahren, bei dem der Glättvorgang durch Glattwalzen erfolgt. Die Maschine zur Durchführung des Verfahrens weist ein Maschinenbett (3) auf, auf dem zur Bearbeitung des Rotors (2) axial verfahrbar mindestens ein Glattwalzkopf (7) angeordnet ist.

An electrostatic chuck comprises an insulating layer with an electrode embedded therein and having a surface to come in contact with a workpiece to be held. Formed on the insulating layer surface is a silicone rubber layer which is filled with reinforcing silica, but free of another filler having an average particle size of at least 0.5 µm. The ESC allows for an intimate contact with a wafer and has an improved cooling capacity.
摘要:
A system for controlling the temperature of fluidic samples includes a device having a first outer surface and a second outer surface which are parallel to one another. The interior of the device contains two or more channels suitable for accommodating samples. The channels lay on a common plane that is also parallel to the first and second outer surfaces. A temperature sensor is positioned between the channels along the common plane. A heater is thermally coupled to one of the two outer surfaces while a heat sink is coupled to the other of the two outer surfaces, thereby establishing a temperature gradient between the first and second outer surfaces. A temperature controller receives sensed temperature input from the temperature sensor and adjusts the heater in response thereto.
