Blum-Novotest’s LC50-Digilog laser measuring system has been redeveloped to enhance the speed, precision and in-process reliability of tool measurement in machine tools. The measuring system is said to generate thousands of measurement values per second while adjusting the measuring speed according to the nominal speed of the tool. The system also measures each cutting edge individually, so that comparisons from the shortest to the longest cutting edge can be made. Run-out errors caused by contamination on the taper of the tool holder are automatically detected. The system also detects any contaminants and cooling lubricants adhering to the tool and deducts them from the result.

The system’s measurement and testing times have been shortened by as much as 60 percent, the company says. An optimized beam shape and a 30-percent smaller focus diameter improve accuracy, and the homogeneity of the laser beam enables more analog measurements. The influence of coolant mist has been reduced to improve accuracy and in-process reliability. The optimized design enables the measurement of tools that are as much as 30 percent bigger, the company says.

Applications include the company’s 3D ToolControl software, which enables continuous digilog-based contour measurement of tools including visualization on the control screen. The SpindleControl technology cycle can be used to record and evaluate the state of a spindle bearing.

    The uses of working gage blocks are as varied as the number of gage blocks in a large set. The working blocks have an intermediate grade and are often used in the inspection or calibration lab, but they may also be found on the shop floor.

  • Surface Texture From Ra to Rz

    The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.
