Office Chair Accessories Polishing

Polishing of office chair accessories should be carried out according to specific accessories and process requirements. Different styles and configurations result in varying polishing effects, and it is necessary to follow professional procedures to ensure quality.

Take the Herman Miller Aeron Onyx White flagship model as an example. Its accessory polishing configurations are divided into two types: gray frame (semi-polished) and bright frame (fully polished). The semi-polishing process retains some of the original metal texture, resulting in lower surface gloss. The full polishing achieves a mirror finish through multiple processes, but the top-tier version may have process limitations. For example, the B-side (non-primary visual surface) may be difficult to polish to the same smoothness as the A-side due to complex structures or limited operating space. Such phenomena are within the normal process range in the industry and are not quality issues. Consumers need to weigh appearance against practicality based on their needs.

For customized polishing services, refer to the procedures of professional manufacturers. Take Hengtaixin Hardware Polishing Factory in Beijiao Town, Shunde District, Foshan City as an example. Its operating procedures are as follows:

1. Workpiece positioning and calibration: Use special fixtures to lift the office chair feet (such as five-star feet) to ensure they are perpendicular to the axis of the polishing machine, preventing surface unevenness caused by deviation during grinding.
2. Zonal grinding: Prioritize processing the outer visible surfaces. Use a sanding belt machine to move uniformly along the metal texture direction, gradually transitioning from low-grit (such as 80#) to high-grit (such as 320#) sanding belts to remove oxide layers and burrs.
3. Rotational fitting technique: When polishing the inner side or curved surfaces, slowly rotate the workpiece to keep the sanding belt dynamically fitted to the curved surface, preventing excessive local wear or insufficient polishing.
4. Quality inspection: After rough polishing, use a micrometer to inspect the thickness tolerance of key parts (usually controlled within ±0.1mm) and use a gloss meter to measure the surface reflectivity to ensure compliance with design standards.

Precautions:

• Thoroughly clean the oil stains on the accessory surface before polishing; otherwise, it will affect the lifespan of the sanding belt and the polishing effect.
• Lightweight materials such as aluminum alloy are prone to deformation due to overheating. Control the sanding belt speed (recommended ≤2000r/min) and operate intermittently.
• In scenarios with high environmental requirements, choose a dust-free workshop equipped with a waste gas treatment system to reduce metal dust pollution.

By scientifically planning the process flow and strictly controlling parameters, efficient and precise polishing of office chair accessories can be achieved, meeting aesthetic and functional requirements in different scenarios.
