Production machine for non-circular workpieces

Abstract

The invention relates to a production machine tool for non-circular workpieces, which is provided with a tool feed unit (1) with a tool holder (2) for accommodating a tool and for pulse decoupling A compensating body (3), wherein the working movement of the tool holder (2) can be realized by a drive device (4) acting between the tool holder (2) and the compensating body (3). The invention proposes that the tool holder (2) is supported by a plurality of rolling bodies (5), the compensating body (3) being suspended on the housing part (7) of the tool feed unit (1) via elastically deformable guide elements (6) , wherein the mass of the compensating body (3) is greater than the mass of the tool rest (2) carrying the tool, the working movement of the tool rest (2) results in a compensating stroke of the compensating body (3), which is only located in the guide element ( 6) within the range of elastic deformability. The guide element (6) thus enables the guiding and resetting of the compensating body (3).

Description

technical field [0001] The invention relates to a manufacturing machine tool for non-circular workpieces, especially a non-circular lathe, which has a reciprocating tool and a tool holder, and a tool for pulse deactivation that can move in reverse relative to the tool and the tool holder. A coupled compensating body, wherein the movement of the tool can be triggered or realized by a drive acting between the tool holder and the compensating body. Background technique [0002] Such a production machine tool is known, for example, from DE 198 10 996 A1 and is used in particular for high-speed production of non-circular turned components or generally in highly dynamic tool feed units. The pulse decoupling serves here to prevent impacts being transmitted with full intensity by the highly dynamic tool movement to the housing or the anchorage on the housing, which would have a negative effect on the machining accuracy.

Problems solved by technology

The pulse decoupling is used here to prevent shocks from being transmitted with full strength by the highly dynamic tool movement to the housing or the anchorage on the housing, which could lead to adverse effects on the machining accuracy

[0003] "Entwicklung und Einsatz einer hochdynamischen Werkzeugzustelleinheit mit hydrostatischer Lagerung, Forschungsgemeinschaft" by M. Weck, J. Hennig e.V., Aachen, October 2002 "It is known that static friction aerostatic or hydrostatic guides in order to avoid the so-called stick-slip effect when guiding the tool holder meet the requirements for precision and uniformity of movement, while Due to the high dynamics of the system, the use of rolling bearings cannot be considered when the travel paths are at the same time small

[0004] However, hydrostatic guides require a high structural complexity due to the conveying lines, supply devices and measures for preventing leakage.

Due to this higher structural expense manufacturing machine tools become more expensive, prone to failure when operating in harsh environmental conditions, and require extensive maintenance
