KGM 281


Owners and manufacturers of machine tools need measuring systems that provide detailed information on machine accuracy with a minimum of time spent on mounting and adjustment. The following measuring systems can satisfy these requirements: The KGM Grid Encoder is for performing circular interpolation tests with small radii and curved path tests, to inspect primarily the dynamic performance of a control Measuring standard - Two-coordinate TITANID phase grating on glass (grid) Signal period - 4 µm in both directions Coefficient of thermal expansion - atherm= 8 ppm/K Measuring range Dia. - 140 mm Accuracy grade - ± 2 µm Evaluation electronics - PC counter card IK 121 V (included) Evaluation Software - ACCOM for AT compatible PCs Recommended measuring steps - 1 µm, 0.1 µm, 0.01 µm To connect this measuring system to a PC, HEIDENHAIN offers the IK121 and IK220 counter cards for insertion in AT-compatible PCs. HEIDENHAIN offers ACCOM Evaluation Software for PCs for measured value acquisition and evaluation according to ISO 230-2 and 230-4 as well as the VDI/DGQ directive 3441. Accom 2.5.3 runs on all AT-compatible PCs: IK121 (W95/98/ME) or IK220 (W95/98/ME/2000/NT4.0).
