Dalian Hongsheng Machinery Enhances Precision Manufacturing with German Mahr’s MarForm MMQ 400 Roundness Tester

Dalian Hongsheng Machinery, a leading player in China’s precision manufacturing sector, has announced the acquisition of the state-of-the-art MarForm MMQ 400 Roundness and Contour Measuring Instrument from German metrology giant Mahr. This strategic investment underscores the company’s commitment to elevating quality control standards for high-precision components1.

Key Features of the MarForm MMQ 400

The newly introduced system boasts:

• High-precision measurement of roundness, cylindricity, coaxiality, and other critical parameters for rotational parts like bearings, shafts, and cylinders1.

• Automated or manual调平调心 (leveling and centering) worktable, ensuring adaptability to diverse工件 (workpiece) sizes and weights1.

• Multi-functional analysis, including waviness, perpendicularity, and straightness, catering to industries such as aerospace, automotive, and energy1.

Strategic Impact

Hongsheng’s adoption of the MMQ 400 aligns with China’s growing demand for精密制造 (precision manufacturing) solutions. By integrating this technology, the company aims to:

• Strengthen competitiveness in global supply chains.

• Reduce production tolerances for clients in高端装备 (high-end equipment) sectors.

• Accelerate R&D for next-generation industrial components.

"The MMQ 400’s accuracy and versatility will revolutionize our quality assurance processes," said a Hongsheng spokesperson. "This aligns with our vision to become a benchmark for精密检测 (precision testing) in Northeast Asia."
