Project Overview
In 2021, a Tier-2 automotive parts supplier in Dongguan commissioned a full axis retrofit of an aging Vertical Machining Center. The goal was to restore positioning accuracy and extend machine life without replacing the entire frame.
Equipment Supplied
- Vertical Machining Center (VMC-850) — 3-axis machining platform
Yousee.Tech Components
- Linear Guide Rail | LGD & Miniature Series
- Ball Screw | SFU & DFU Series
- Servo Motor | 400W~1.5kW Series
Implementation
Our team replaced the original plain-bearing ways with preloaded linear guide rails and precision ground ball screws on X, Y, and Z axes. The open-loop stepper drives were upgraded to closed-loop AC servo motors with 17-bit encoders, matched to planetary reducers on the Z-axis.
Results
- Positioning repeatability improved from ±0.02 mm to ±0.005 mm
- Surface finish (Ra) improved by 35%
- Reduced scrap rate by 18% over the first 12 months
