The DBB Double Ball Bar is a telescoping double-ball-bar linear encoder for performing circular interpolation tests with large radii to inspect primarily the machine tool geometry

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 DBB Double Ball Bar is a telescoping double-ball-bar linear encoder for performing circular interpolation tests with large radii to inspect primarily the machine tool geometry Measuring standard - Scale with DIADUR graduation and reference mark Signal period - 10 µm Measuring range - ± 5 mm Length between ball centers - 150 mm, 200 mm, 250 mm, 300 mm System accuracy - ± 1 µm Evaluation electronics - PC counter card IK 121 A (included) Evaluation software (option) - ACCOM for AT compatible PCs Recommended measuring step - 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).
