Pain Point 1: High dust levels, heavy pollution, and health hazards

Improvement Solution: Install a simple dust collection hood and connect an external industrial vacuum cleaner; install baffles around the workbench and dust collection troughs on the floor; ensure operators wear dust masks and goggles, and regularly clean dust from the machine.

Pain Point 2: Uneven polishing results, prone to scratches, and inconsistent batch performance

Improvement Solution:

1. Standardize sisal wheel specifications and regularly adjust and level them to avoid uneven wheel surfaces;

2. Install a simple limiting and positioning bracket to fix the polishing angle and distance of the workpiece, reducing differences in human feel;

3. Divide the polishing process into two stages: rough polishing and fine polishing, using sisal/cloth wheels with different grit sizes to reduce scratches.

Pain Point 3: Reliance on experienced workers, low efficiency, and high consumable consumption

Improvement Solutions

1. Create simple tooling fixtures for fixing and polishing small parts, making it easy for beginners to operate;

2. Standardize the use of sisal wheels, allowing for regular maintenance instead of direct replacement, reducing consumable costs;

3. Implement dual-station rotation for one machine, reducing idle time and increasing single-machine productivity.
