Office Chair and Table Leg Polishing

Polishing of office chair and table legs requires different methods based on different objects and needs. Here are the specific operation procedures:

Polishing of office chair legs
You can refer to the polishing process: First, lift the workpiece and align it, then move it to the polishing work area for preparation. When polishing, prioritize the outer side. During rotation, ensure that the chair legs precisely fit the sanding belt to avoid excessive local wear or omissions. If there are burrs or minor scratches on the chair legs, you can first use low-grit sandpaper for preliminary treatment and then gradually transition to high-grit sandpaper to complete the polishing.

Polishing of table corners (flattening treatment)

• Manual polishing: Suitable for scenarios where a handmade texture is desired or for minor repairs.
  1. Select 80-120 grit coarse sandpaper and sand along the wood grain direction to remove protruding burrs and obvious unevenness until the surface is basically flat.
  2. Switch to 240-320 grit medium sandpaper and continue sanding along the wood grain to eliminate the marks left by the coarse sandpaper and make the surface delicate and smooth.
  3. Finally, lightly sand with sandpaper of 600 grit or above to further enhance the surface texture.
• Electric polishing: Suitable for scenarios with significant wear or requiring quick treatment.
  Use a small angle grinder equipped with a sanding disc, control the force and angle to avoid damaging the surrounding paint or solid wood surface. After polishing, you can apply wood wax oil or varnish as needed to protect the surface.

Rounding treatment of table corners

• Evaluation and tool selection:
  First, evaluate the material of the table corner (such as solid wood or veneer) and its sharpness, and clarify the polishing goal (such as a complete rounded corner or a slight chamfer). Manual tools (such as sandpaper and sanding blocks) are suitable for small-scale fine adjustments or veneer furniture, while electric tools (such as angle grinders and trimming machines) are more efficient for large areas or hard wood.
• Operating posture:
  Hold the tool with both hands, with the thumb and index finger roughly aligned with the extension line of the table corner. Stand with your feet shoulder-width apart, keep your weight on the balls of your feet, and use a slight rotation of your hips to drive the movement of your arms and the tool to ensure stability.
• Polishing points:
  Apply pressure evenly and control the consistency of the arc to avoid local over-polishing or under-polishing. During the process, frequently check the polishing effect and make timely adjustments. After completion, use a slightly damp cloth to remove dust, wipe dry with a dry cloth, and finally apply wood wax oil or varnish as needed.
