Abstract:
Die Erfindung beschreibt eine Poliervorrichtung (100) zum Polieren eines Bauteils (200) mit einem länglichen Polierelement (110), welches parallel zu der Längsachse (z) der Bauteil (200) gegen die Oberfläche (205) der Bauteil (200) gerichtet ist. Dabei ist das Polierelement (110) in seiner Längserstreckung in benachbarte Teilsegmente (110-1, 110-2,... 110-n) ausgebildet. Ein Gehäuse (120) dient zur Aufnahme des Polierelementes (110). Zwischen einer Auflagefläche (123) des Gehäuses (120) und dem Polierelement (110) ist ein Druckelement (130) angeordnet, zum Anstellen und Andrücken des Polierelementes (110) gegen das Bauteil (200). Dabei ist das Druckelement (130) als mindestens ein druckbeaufschlagbarer Schlauch ausgebildet.
Abstract:
An einem Werkstück (1) befinden sich erste Längenabschnitte (2a, 2b, 2c), die zu der durchgehenden Längsachse (5) rotationssymmetrisch sind und durch spitzenloses Rundschleifen geschliffen werden sollen. Das Werkstück (1) hat auch einen zweiten Längenabschnitt (3), der zu der Längsachse (5) rotations-unsymmetrisch verläuft und bei Rotation zur Unwucht führen würde. Deshalb wird ein Ausgleichsgewicht (6) mit einer radial verlaufenden Ausnehmung (7) auf den zweiten Längenabschnitt (3) aufgesetzt (Pfeil 9, Gleitrippen 8). Das Ausgleichsgewicht (6) führt weitgehend eine gleichmässige Verteilung der Drehmassen herbei, verringert damit die Unwucht auf eine sehr geringe Rest-Unwucht und ermöglicht ein prozesssicheres und genaues spitzenloses Rundschleifen.
Abstract:
An abrading method which is excellent in loading resistance and durability, and allows a minute finishing to be provided in a short period in the case of abrading a curvilinear surface of a workpiece.
Abstract:
The invention relates to a device for the grinding of drafting rolls (7) with an emerizing roll (2), at which a drafting roll (7) can be advanced to the emerizing roll casing on one side thereof by an automatically driven carriage (6) holding the drafting roll, the carriage (6) being mounted on a first guiding element (5), and a second guiding element (8) being secured to the emerizing roll (2) on the side opposite the first guiding element (5). This second guiding element (8) supports a hand-driven second carriage (9), and the direction of rotation of the emerizing roll is reversible.
Abstract:
A CNC cylindrical grinding machine comprising a bed, a worktable movable relative to the bed along a linear path, wheelhead movable in a direction generally perpendicular to the direction of worktable travel, a rotatable grinding wheel mounted thereon for engagement with a workpiece mounted on the worktable, wheel drive means on the wheelhead for rotating the grinding wheel, headstock and tailstock means carried by the worktable for supporting a workpiece at its opposite ends, drive means associated with the headstock and tailstock means for rotating the workpiece, worktable drive means for effecting movement of the worktable relative to the bed and therefore the wheelhead, wheelhead drive means for effecting movement of the wheelhead and therefore the grinding wheel towards and away from the workpiece, control means by which all of the drive means and particularly the worktable and wheelhead drive means, are controlled, thereby to enable the workpiece to be positioned axially and rotationally relative to the grinding wheel, and to move the grinding wheel into engagement with the workpiece, further comprising transducer means for generating position and speed of rotation signals from at least the worktable and the wheelhead, and the headstock drive, for supply to the said control means, thereby to enable complex shapes and forms to be ground in the surface of the workpiece.
Abstract:
Vacuum cleaner for industrial and domestic applications, in which the sucked up dust is collected in a vessel (1) filled with water (7). The necessary sucking action is generated with an air pump (2) or with a venturi (16), located in a suction tube (3) in front of the vessel (1). In order to realize complete washing out of the dust, the vessel (1) is provided with at least one grid (9) through which the air bubbles can escape.
Abstract:
The invention relates to a part for polishing, comprised of a substrate of a rigid material and an underlying flexible support. The substrate consists of contacts (1) separated by intervals (3, 4), said intervals (3, 4) defining at least two lines (3) extending in the same direction from one side of the support to the other.
Abstract:
A machine tool comprising: a machine frame; a work carrying assembly for carrying a workpiece, carried by said machine frame for reciprocal movement along a work axis; and a cover assembly carried by said machine frame and including cover portions disposed to cover selected areas of said machine frame proximate said work axis. The cover assembly is not connected to the work carrying assembly but is operable to effect movement of said cover portions commensurate with movement of said work carrying assembly. The work carrying assembly includes a work carriage and said machine frame mounts a slideway proximate said axis and extending in the same direction as the work axis. The work carriage extends in the direction of said work axis but is of lesser extent than said slideway such that portions of said slideway to either one, the other or both extremities of said carriage assembly may be exposed upon said reciprocal movement of said work carrying assembly work carriage. The cover portions cover the slideways that may so be exposed. A first cover portion is disposed to cover the slideway to one side of the work carriage and a second cover portion is disposed to cover the slideway to the other side of the work carriage. Each cover portion includes a plurality of telescoping, slidably interrelated covers which are moved with respect to each other to cover more less of said slideways as such become exposed or become covered by the work carriage.
Abstract:
A machining location for machining workpieces, comprising: a machine tool; an enclosure for said machine tool that encloses the entire machine tool within a predetermined space; workpiece storage within said predetermined space for storing workpieces at least prior to being worked on by said machine tool and for subjecting such workpieces when so stored to said machining environment to become oriented thereto. The machining location is mounted and supported to be separate from and independent of said machine tool so that vibrations are not transmitted from said enclosure to said machine tool. The machining location further comprises ambient environment controls for effecting control of at least the temperature of the air within said predetermined space.
