Description

The MarForm MMQ 400 is a flexible and fully automated solution for precision measurement of form, position, and surface characteristics. Designed with high-precision motorized axes in the Z and X directions, it ensures repeatable and accurate results even for complex or heavy workpieces. The integration of the MarWin platform software enables measurement of roughness, waviness, and contour in addition to traditional form assessments.

This system offers high versatility and cost-effectiveness, paying for itself quickly by streamlining measurement processes. Its automatic centering and tilting table allows faster alignment and maximizes productivity. The MarForm MMQ 400 is widely used across industrial and medical fields, including machine building (bearings, ball screws, shafts), automotive (steering systems, gearboxes, motors), and medicine (hip and knee endoprostheses, medical screws, dental implants).

By combining automated measurement sequences with smooth, precise axes, the MarForm MMQ 400 ensures high-quality inspection and reliable data for quality control, production monitoring, and research applications.
