Specialists in the investment casting and machining of alloy metals, such as aluminium and titanium, which are primarily used for jet aircraft engines and airframes, have to measure the dimensions of the blades after surface grinding.After casting, the turbine blades undergo surface grinding to complete the collaboration of surfaces. The dimensions of the blade post-grind then need to be accurately measured as the initial proportions from the casting will have changed slightly. A precision process application is required to confirm to final specification requirements (dimensional accuracy and surface finish).
Using the digital spring loaded displacement probes, the measurement from the desired location on the turbine can be taken, and fed into the digital readout. High resolution, excellent linearity, long life precision bearings, and an IP65 ensure that probed maintain their performance for millions of cycles.
