Project Overview
A mid-sized laser cutting factory in Qingdao was processing 8 mm carbon steel and 6 mm stainless steel sheets for agricultural machinery parts. After laser cutting, every part carried sharp burrs, slag deposits and oxide skin along the cut edges. Manual grinding with angle grinders required four workers per shift and created inconsistent edge quality, which delayed welding and coating downstream.
Challenges
- High labor cost: four dedicated workers only for deburring.
- Inconsistent quality: manual grinding left some edges sharp, others over-ground.
- Safety risks: operators frequently suffered cuts from sharp burrs.
- Dust and noise: grinding dust filled the workshop and exceeded local OSHA limits.
Recommended Machine
After reviewing workpiece drawings and daily output (approximately 400 parts per day), we recommended the BG-RR-1300 Heavy-Duty Sheet Metal Polishing Machine. Its 1300 mm working width covers two standard 500 mm parts side-by-side, and the heavy-duty abrasive belt station removes thick slag and oxide skin in a single pass.
Workflow Integration
- Loading – Cut sheets are placed on the infeed conveyor in stacks of 20–30 pieces.
- Deburring & Slag Removal – The first abrasive belt head removes heavy slag and large burrs at 15 m/s belt speed.
- Edge Rounding – The second rotary brush station breaks sharp edges to a uniform R1–R2 radius.
- Surface Cleaning – A final scotch-brite brush removes oxide skin and leaves a clean, weld-ready surface.
- Collection – Finished parts exit onto a sorting table for QC inspection.
Results
- Labor reduced from 4 workers to 1 machine operator.
- Cycle time per part dropped from 45 seconds (manual) to 8 seconds (automatic).
- Edge consistency improved; welding wire consumption decreased by 12 % because of better fit-up.
- Dust extraction module (optional BG-DC-3000) captured 99 % of particulate, bringing the workshop into compliance.
Customer Feedback
“We were skeptical about replacing manual grinding, but the BG-RR-1300 paid for itself in under eight months through labor savings alone. The edge quality is now so consistent that our welding reject rate fell by 60 %.” — Production Manager, Qingdao Agricultural Equipment Co.
