Trustworthy 45 steelCNC turning of flat mask shaft CNC Machining Service

We specialize in the precision CNC machining and manufacturing of mask shafts—key drive shafts in automated production lines for various types of flat mask shafts. We rely on high-precision multi-axis CNC milling and turning centers, professional surface treatment processes, and a rigorous dynamic balancing testing system.

Flat mask shafts typically need to operate continuously at speeds of hundreds of revolutions per minute or even higher, while simultaneously enduring impact loads from welding indenters and wear from friction with non-woven fabric. Aluminum alloys such as 6061-T6 and 7075, with their lightweight and low inertia advantages, are the preferred materials for high-speed mask shafts; while stainless steels such as 304 and 420, with their excellent corrosion resistance and wear resistance, are used in applications with special hygiene requirements or high wear.

I、We provide a full-process service from shaft design optimization, material selection, process development, prototype manufacturing to mass production. Our engineering team is proficient in the machining technology and application requirements of various flat mask shafts:

1. Earloop Welding Shaft: Used to drive the earloop welding wheels, requiring extremely high radial runout accuracy and surface hardness.

2. Pressure Roller Shaft: Used to convey non-woven fabric, requiring a smooth surface and good wear resistance.

3. Folding Shaft: Used for folding the edges of masks, requiring precise contour shape and position.

4. Drive Shaft: As the core of power transmission, requiring excellent torsional stiffness and dynamic balance performance.

II. Precise Matching of Materials and Applications

1. Lightweight High-Speed ​​Shaft: Made of 6061-T6 or 7075 aluminum alloy, precision machined and hard anodized, suitable for high-speed rotating welding shafts and pressure rollers. Shafts

2. High Wear-Resistant Steel Shafts: Made of 304 or 420 martensitic stainless steel, heat-treated and precision ground, for high-wear applications or applications requiring frequent cleaning.

3. Composite Structure Shafts: Available with an aluminum core and steel sleeve composite structure, balancing lightweight design with localized wear resistance.

III. We have built a complete precision manufacturing chain for aspect ratio shafts, focusing on achieving a balance between high precision, high surface finish, and long-term stability:

1. Precision Reference Machining: Utilizing high-precision CNC lathes, shaft blanks are precision turned, completing the machining of the center hole, outer diameter, end face, and steps in a single setup. This establishes precise and unified process references, fundamentally ensuring coaxiality in subsequent machining.

2. External Cylindrical Precision Grinding (Core Technology): For mask shafts with extremely high coaxiality requirements, CNC cylindrical grinding machines are used for final finishing, achieving IT5-IT6 level precision and a mirror-grade surface roughness of Ra ≤ 0.2μm, ensuring minimal runout during rotation.

3. Complex Feature Machining: Multi-axis machining centers are used for precision milling of keyways, flat sections, locating holes, and mounting threads to ensure precise fit with welding wheels, bearings, couplings, and other components.

Heat Treatment and Dimensional Stabilization: Based on material and performance requirements, heat treatments such as tempering, aging, and surface quenching are provided, along with stress-relief annealing to eliminate machining stress and ensure long-term dimensional stability.

IV. Surface Strengthening and Treatment

1. Hard Chrome Plating: Hard chrome plating is applied to the steel mask shaft to obtain a wear-resistant surface with high hardness and a low coefficient of friction.

2. Mirror Polishing: Precision polishing is performed on the surface to obtain an ultra-smooth surface with Ra ≤ 0.1μm, minimizing conveying resistance.

3. Dynamic Balancing: For high-speed rotating mask shafts, single-sided or double-sided dynamic balancing at G1.0 or G0.4 level is performed on a high-precision dynamic balancing machine to eliminate vibrations during high-speed operation and ensure welding accuracy and equipment lifespan.

V. Advanced Manufacturing System Ensures Coaxiality and Surface Quality

1. We are equipped with high-precision CNC lathes, CNC cylindrical grinders, five-axis machining centers, hard anodizing production lines, and high-precision dynamic balancing machines. This addresses the core aspects of mask shaft manufacturing: coaxiality and surface finish.

2. Single-Setup Machining: We complete the machining of all external cylindrical features in a single setup whenever possible, fundamentally avoiding coaxiality errors caused by secondary setups.

3. Center Hole Datum: We use a precision center hole as the grinding datum to ensure the coaxiality of shafts with a length-to-diameter ratio.

4. In-Machine Measurement and Compensation: Key processes are integrated into an in-machine measurement system, which monitors dimensions in real time and automatically compensates for machining errors.

We deliver not just a flat mask shaft, but a core transmission component for automated equipment that has undergone precision design, extreme manufacturing, and rigorous verification, enabling high-speed, stable, and long-life operation. From single-piece prototype shafts to batch production, we are committed to becoming the most trusted manufacturing partner for mask machine and non-woven fabric equipment manufacturers in the field of precision shaft parts.
