Measuring Methods - process-integrated quality Control  

Inductive workpiece measurement is a non-contact measuring method for measuring deep-hole drilled, shaft-shaped workpieces, such as turbine shafts, where the outer contour of the workpieces is to be precisely matched to the inner contour in order to achieve a uniform wall thickness of the workpieces. The process can be used for all electrically conductive materials such as simple steels as well as superalloys and nickel-based alloys such as Inconel 718, and can be integrated fully automatically on our horizontal machining centers. In the process, a specifically calibrated eddy current sensor is positioned and moved via the machine axes of the boring bar unit in the working area of the machine within the deep-hole drilled workpiece. The distances between the sensor and the workpiece are then measured at any fineness via the rotation of the workpiece. The measuring method is insensitive to environmental influences such as temperature fluctuations or foreign substances, and can be used for a wide range of materials.

Scanning workpiece measurement is a process in which elements and contours of workpieces are measured circumferentially by means of probes with constant workpiece contact. This enables fast and highly accurate measurements with a high point density. In order to measure concentricity or roundness and diameter to an accuracy of 1 µm, a temperature-stable reference is required. In addition, complete element geometries, roundness, straightness, and flatness as well as form deviations can be measured even for complex contours and free-form surfaces. We integrate various scanning systems for workpiece measurement into our horizontal and vertical machining centers in order to measure the parts quickly and process-integrated in their raw state, as well as after individual process steps and final machining. This allows us to effectively improve machining accuracies, reduce scrap, and increase the productivity of your manufacturing.

Tactile workpiece measurement is a method by which workpieces can be measured in-process with high precision by probing from all sides. Parameters such as workpiece geometry, straightness, flatness, roundness, and the surface condition in terms of roughness and waviness of the workpiece can be determined independently of its size and weight using various predefined touch points. Tactile workpiece measurement are integrated into all our vertical and horizontal turning and machining centers. We measure the workpiece blank precisely before the start of machining to adjust the machining process to fit exactly. Any tolerance deviations can be determined and corrected if necessary while machining is still in progress. This allows us to effectively improve machining accuracies, reduce scrap to a minimum, and increase the productivity of your production.

Optical tool measurement is a non-contact method of measuring tools inside the machine by means of a laser. It is suitable for both rotationally symmetrical tools and turning tools. Factors influencing the process, such as changed cutting edge geometries or wear, are detected with maximum repeatability and absolute accuracy, with tools being replaced as required. By integrating various optical systems for tool measurement into our turning and machining centers, we can measure tools quickly and, in a process-integrated manner, improve machining accuracies, and reduce scrap.

 

Tactile tool measurement is a process in which tool cutting edges are measured by means of probing. We integrate measuring cubes for tactile tool measuring in all our vertical and horizontal turning and machining centers in order to measure the tools used in any cutting edge position in a process-integrated manner, and to adjust them automatically. In the case of rotationally symmetrical tools, a breakage check can also be carried out. This allows us to effectively improve machining accuracy, reduce damage and scrap, and increase the productivity of your production.
