NAAMS Standard Flying Cam Units MGFNS / MEFNS 70 (θ=45-60) (Part Numbers)

Question: What is the primary function of the NAAMS Standard Flying Cam Unit MGFNS / MEFNS 70?

Answer: The Flying Cam Unit is designed for side piercing, trimming, and flanging operations in stamping dies. Its cam-driven mechanism allows precise horizontal motion synchronized with the press stroke, ensuring accurate material forming and cutting.

Question: How does the 70 mm cam width affect the performance of the Flying Cam Unit?

Answer: The 70 mm cam width provides a stable contact surface, enhancing load distribution and structural rigidity. This allows the NAAMS Standard Flying Cam Unit to maintain alignment and precision during high-load or repetitive operations, especially in automotive die applications.

Question: What are the advantages of the adjustable tilt angle (45°–60°)?

Answer: The adjustable tilt angle range of 45° to 60° offers flexibility in die design by enabling optimal motion transfer between the cam driver and pad. Lower angles favor longer stroke motion, while higher angles are ideal for compact layouts requiring space efficiency and strong impact resistance.

Question: What materials and design standards are used in the MGFNS / MEFNS 70 cam unit?

Answer: The MGFNS / MEFNS Flying Cam Units are built to NAAMS global standards, ensuring compatibility across international tooling systems. Components are made from high-strength alloy steel, with hardened wear surfaces for durability and reduced maintenance in heavy-duty stamping environments.

Question: What is the role of different spring specifications like GK, ISO, NGK, and NISO?

Answer: These spring specifications define the return force and operating characteristics of the Flying Cam Unit.
• GK / NGK: High-load springs for demanding forming and trimming operations.
• ISO / NISO: Balanced force springs suitable for standard piercing and flanging applications.
Selecting the appropriate spring ensures smooth return motion and consistent part quality.

Question: How is maintenance performed on the NAAMS Standard Flying Cam Unit?

Answer: Maintenance involves periodic inspection of cam sliders, guide surfaces, and springs. Lubrication points should be serviced regularly to minimize wear. The modular design of the Flying Cam Unit allows quick disassembly for component replacement, ensuring minimal production downtime.

Question: What are the benefits of using the NAAMS standard in Flying Cam Units?

Answer: Adopting the NAAMS Standard Flying Cam Unit ensures dimensional interchangeability, simplified global sourcing, and compatibility with standardized die components. This standardization reduces lead times, enhances production consistency, and supports uniform tooling integration across manufacturing sites.
