Product Information


ZEISS RONDCOM 73 is a universal roundness/spindle tester with a large measuring range for heavy workpieces.
The spindle form tester features high rotational accuracy and minor parallelism errors.

The working range of the RONDCOM 73 A is exactly where other form testers reach their limits. The form measuring station features excellent rotational accuracy and a substantial measuring range in spite of its compact design. Heavy workpieces also pose no problem for this precise spindle form tester. Comprehensive collision protection, fully automated alignment of the workpiece and automated CNC measuring runs set the RONDCOM 73 A apart. The ACCTee PRO software included offers an intuitive user interface and guides the user through the entire measuring process.
