摘要:
A touch-sensing device (60) is used to determine the spacing of the cutting teeth (12) of a workpiece (10) in relation to a workpiece holder (44), said touch-sensing device (60) being in a measuring position reached by the tip (18) of a cutting tooth (12) of the workpiece (10) when the workpiece slide (42) is displaced in the direction of the swivel axis (A), said cutting tooth (12) pointing in the direction of the swivel axis (A). The touch-sensing device (60) comprises a barrier (70) whose length (L) in the middle plane (G) transversal to the workpiece slide rail (40) is greater than the maximum tooth spacing (T) of the workpieces (10). The inventive machine has a control mechanism which is programmed so that the touch-sensing device (60) is activated before an advancing device (50) if the tip (18) of a cutting tooth (2) is not located on the swivel axis (A).

Disclosed is a device comprising a mandrel (12), a steady rest (14), and a dog (30). At least the mandrel (12) is mounted so as to be rotatable about the longitudinal axis while the dog (14) is fixed to the mandrel (12) and can be engaged with the workpiece (50) when the workpiece (50) is clamped between the mandrel (12) and the steady rest (14) in such a way that the dog (14) transmits a rotary movement of the mandrel (12) to the workpiece (50). The dog of the inventive device is provided with a spring element (30) which can be coupled in a pretensioning manner to the workpiece (50) so as to transduce torque.

摘要:
An electrode wire (20) is drawn from a feed reel (22), led via guide rollers (24-30) to a machining section (32) and finally wound onto a winding reel (40). The electrode wire (20) is guided in such a way that it remains in the same plane perpendicular to the axis when wound onto the winding reel (40) and when drawn from the feed reel (22). Both reels (22, 40) are mounted on a common carrier (50) which can move on a line parallel to the axes of the reels (22, 40). A measurement device (70) is arranged between the feed reel (22) and first guide roller (24) and measures deviations in the position of the electrode wire (20) from a predetermined position. The carrier (50) is linked to a slide drive (60) which corrects deviations noted in the position of the electrode wire (20) unwinding from the wind-off reel (22) by axial displacement of the carrier (50) and thus ensures that the used electrode wire (20) is wound correctly onto the winding reel (40).
摘要:
The invention relates to an apparatus (10) for machining plate-shaped or cylindrical workpieces (70) that are provided with cutting teeth (S). Said apparatus (10) comprises a machine base (12), a machining device (14) that is movable relative to the machine base (12), and a workpiece positioning device (16) which is movable relative to the machine base (12). The machining device (14) encompasses a machining bridge (18) which can be linearly displaced relative to the machine base (12) along a first axis (Y1) in space, and a machining arm (20) that can be linearly displaced relative to the machining bridge (18) along a second axis (X1) in space. A machining unit (26) comprising a machining tool (28) is mounted on the machining arm (20) so as to be pivotable about a swiveling axis (E1) which extends substantially perpendicular to a plane defined by the first and second axis (Y1, X1) in space. The workpiece positioning device (16) is equipped with a bearing carriage (32) which can be linearly displaced relative to the machine base (12) along a third axis (Z1) in space. A tilting bearing arrangement in which a workpiece accommodating arrangement (44) is mounted so as to be tiltable about a tilting axis (B1) is provided on the bearing carriage (32).

The invention relates to a device (10) for machining workpieces (36), particularly peripheral areas of disc-shaped workpieces such as circular saw blades, comprising: a clamping device (38) for fixing the workpiece (36) to be machined in machining positions; a machining device (30) for machining the workpiece (36), and; an advancing device (40) for displacing the workpiece (36) between a first machining position and at least one other machining position. According to the invention, the machining device (30) for machining the workpiece (36) can be displaced relative to the workpiece (36), which is fixed in the machining position, by means of a single or multiple axis arrangement (14) that can be controlled per axis. The advancing device (40) has a contact element (44) that can be brought into contact with the workpiece (36). This contact element is coupled to the single or multiple axis arrangement (14), and at least one axis of the single or multiple axis arrangement (14) can be controlled for displacing the workpiece (36) between the first machining position and the at least one other machining position by means of the advancing device (40).
