摘要： A method and device for disturbance sensing in the drive system of a numerically controlled machine tool or similar device is disclosed, in which at least one drive motor for positioning of a machine part being moved such as an advance slide or an X/Y cross-slide is coupled via one or more transmission elements in which the position of the moving machine part is measured directly on the machine part and also indirectly in at least one location in the transmission chain. Direct and indirect position measured values are compared and the measured value comparison value is used to record a disturbance with consideration of the actual operating conditions, such as machining speed and acceleration/delay, optionally moved masses and machine-specific process forces upon fulfillment of a specific criterion.

摘要： A wire tensioning system for a wire-shaped working electrode of a spark erosion machine and a procedure for the tensioning of the working electrode. The working electrode at least nearly circumferentially encompasses a braking roller in a wire entry zone and/or a tensioning roller in a wire withdrawal zone. A nozzle is assigned to the braking and/or the tensioning roller such that the nozzle exerts a tensile force on the working electrode to tension the wire.

摘要： A wire transport system for an electrical discharge machining apparatus with at least one wire electrode includes a wire supply, a wire tensioner and/or a wire disposer arranged such that the entire wire transport is automated. The wire is automatically transported from the wire supply to a processing zone, in particular, by a fluid. Due to the elimination of fluctuations in the uniform movement of the wire, a wire transport with less vibration is attained, and the processing quality is improved. In addition, a higher reliability is achieved.

摘要： An EDM machine for machining a workpiece is disclosed. The EDM machine includes a machine frame having a central stationary machine body and a machining electrode to machine the workpiece. Machining occurs by producing a relative movement in at least one of an X axial direction and a Y axial direction between the machining electrode and the workpiece. The machine also includes a first axial slide for moving at least one of the workpiece and the machining electrode in the X axial direction, and a second axial slide for moving at least one of the machining electrode and the workpiece in the Y axial direction. The first axial slide is mounted in a substantially vertical plane on the machine body for lateral movement in a substantially horizontal direction.

摘要： A machine tool with a machine frame is disclosed. A first tool guide is provided on the frame to guide a tool to a first guide position. The first tool guide is a movable gantry carrier with a movable first sliding carriage. The tool guide can be moved with respect to the machine frame in a first plane along a first direction and in a second direction which is orthogonal with respect to the first direction. Furthermore, a second tool guide is provided on the machine frame to guide the tool to a second guide position. The second tool guide can be moved with respect to the machine frame in a second plane along a third direction and a fourth direction which is orthogonal to the third direction, independently of the first tool guide. Finally, a tool holder is provided on the machine frame to hold the machined part. The machined part is led between the first and the second guide positions of the tool. The second tool guide is a movable gantry carrier with a movable second sliding carriage.

摘要： The invention presents a spark erosion machine, having a travelling wire electrode and an optical measuring means to measure the deflection of the travelling wire electrode. The measuring means includes a light source (10) producing a homogeneous parallel bundle of rays. A sensor assembly (1,11) measuring the light beam which comes from the light source and is shaded by the travelling wire electrode (9) is designed such as to absorb a light quantity which is dependent in one-to-one correspondence on the relative position of the travelling wire electrode (9). An evaluation circuit connected downstream of the sensor assembly provides an electrical signal indicating the deflection of the travelling wire electrode from its straight position. By means of this electrical signal, the relative positions of the guide heads of the travelling wire electrode and that of the workpiece can be corrected in such a way that machining errors caused by the deflection of the travelling wire electrode can be avoided.
