Multiple operator station for machine tools

Multiple operator station (1) for machine tools designed in particular for chip removal along several axes, comprises several operator units (345) suitable for coupling with a tool or a workpiece, these operator units (345) being fitted on a bearing structure (2) that is curved in shape with the concave part facing downwards, and positioned in such a way that below the zone (6) in which the part is positioned during machining, there are no functional parts of the machine subject to movement of one part in relation to another.

Liquid filtering system in machine tools

A liquid filtering system in machine tools which uses, in a recycling circuit, a work tank, a dirty liquid tank, a filter and a clean liquid tank in which water of a very low conductivity is used and adding at least one ferric oxide flocculent based on a polyelectrolyte polymer to the low conductivity water.

Reference object for coordinate measuring machines and machine tools

The invention relates to a low-cost, low-weight, highly stable reference object, easy to handle, for the measurement of the errors of geometry of coordinate measuring machines and machine tools. The reference object consists of an array of probing elements in the form of rings, spheres, or flats, each representing reference points by means of their surface geometry. The probing elements are glued between two panes of a geometrically stable material, establishing a firm connection between these panes. Holes in the panes enable the measuring probe of the machine under inspection to probe the reference elements' surfaces. The resulting box-type structure of the reference object gives it the said advantages of low weight, low price, and high stability.

Position drive, in particular for use in machine tools, and tool head having such a position drive

The invention relates to a position drive for a tool head for use in machine tools. The tool head comprises a base body (12), a tool shank (16) which protrudes axially over the base body (12) and is coupleable to a rotating machine spindle (14), and a thrust member (18) which is movable with respect to the base body (12) and which serves to move at least one tip holder or cutting tool (76). Further, an electric motor arrangement (24), which is coupleable to the thrust member (18), and a power supply device (26) for the motor arrangement (24) are positioned on the base body (12). In order to ensure a compact construction having an efficient motor arrangement, a hollow shaft (50) is borne rotatable about an axis of the base body (12), which is concentric with respect to a displacement axis (52) of the thrust member (18), and the hollow shaft (50) has an internal thread which engages in an external thread (42) of the thrust member (18). The hollow shaft (50) has a toothed ring (62) which is positioned concentric with respect to the external thread (42), for the engagement of at least one gear (70) which is positioned on a driven shaft (68) of the motor arrangement (24).
