Deep drilling device

A deep drilling device suitable for drilling in workpieces, particularly crankshafts, holes at different positions and / or in different orientations relative to a work longitudinal axis, has a deep drilling unit and a work holding unit cooperating therewith. The deep drilling unit permits parallel displacements of the deep drilling tools in a horizontal X direction and a vertical Y direction, as well as a tool feed parallel to the spindle axis. The tool holding device receives one or more crankshafts in such a way that their longitudinal axis is horizontally oriented and permits a rotation about the longitudinal axis and a swivelling of the workpieces about a vertical rotary axis. As a result both different tilt angles of the holes relative to the work longitudinal axis and also different positions of the holes relative to the circumference of the workpieces can be obtained.

Deburring by hobbing with integrated secondary deburring without a smoothing tool

The invention relates to a method for tooth-machining of workpieces (3), especially gear wheels, comprising milling, deburring by hobbing and integrated secondary deburring. The method proceeds on a machine tool (1) having two workpiece spindles (11, 12) which may exchange places. A workpiece (3) is mounted on a first workpiece spindle (11), followed by the workpiece spindles (11, 12) exchanging places, followed by pre-milling and, where applicable, cutting (=deburring by shaving) of the workpiece (3), followed by a further exchange of places, followed by chamfering and cutting of the workpiece (3), followed by a further exchange of places, followed by a finish-milling of the workpiece (3), followed by a further exchange of places, followed by a workpiece change. At the same time, the same procedure takes place on the second workpiece spindle (12), staggered in time by an exchange of places of the workpiece spindles (11, 12). With the method according to the invention, well-deburred toothed workpieces (3) may be produced quickly and at low cost.

Monitoring system comprising infrared thermopile detector

The present invention relates to a semiconductor processing system that employs infrared-based thermopile detector for process control, by analyzing a material of interest, based on absorption of infrared light at a characteristic wavelength by such material. In one embodiment, an infrared light beam is transmitted through a linear transmission path from an infrared light source through a sampling region containing material of interest into the thermopile detector. The linear transmission path reduces the risk of signal loss during transmission of the infrared light. The transmission path of the infrared light may comprise a highly smooth and reflective inner surface for minimizing such signal loss during transmission.

Pallet changer apparatus

In a pallet changer apparatus, a pallet changing arm is connected to a motor via a raising / lowering mechanism and an intermittent drive unit. During operation of the motor, the pallet changing arm is raised from a lowermost position to an uppermost position, and is held at the uppermost position, and then is lowered from the uppermost position to the lowermost position. The pallet changing arm is also connected to the motor via a turning mechanism and a second cam drive portion. During operation of the motor, the pallet changing arm is turned while being held at the uppermost position. The pallet changing arm is moved up and down and turned by using the single motor provided above a table. The table below the pallet changing arm is reduced in size so as to allow an operator to perform operations without being impeded by the table. The structure also eliminates the need to determine the drive time of a plurality of drive force sources based on output signals of sensors, thereby decreasing the possibility of a malfunction and improving reliability.
