Automatic PCB Grinding Brushing Machine (GE-GB650)
Progressive 300# → 500# → 800# abrasion sequence with oscillating brush and pressure control — 650 mm working width, 28 kW, for high-volume multilayer and heavy-copper PCB pre-treatment.
Automatic PCB Grinding Brushing Machine (GE-GB650)
GE-GB650 is built for high-volume multilayer PCB lines and heavy-copper PCB where the progressive abrasion sequence is needed to remove thick oxide, residual plating flash and heavy contamination in a single pass.

GE-GB650 FAQ
GE-GB650 is an automatic PCB grinding brushing machine used for high-volume multilayer and heavy-copper PCB pre-treatment. The progressive 300# / 500# / 800# abrasion sequence removes thick oxide and contamination in a single pass.
GE-GB650 runs three brush stations in sequence — 300# (coarse) → 500# (medium) → 800# (fine). Each station has its own motor and pressure control. The progression removes heavy oxide first, refines the surface, then burnishes.
GE-GB650 draws 28 kW from a 380 V / 50 Hz three-phase supply — including the six brush motors (2 per stage), the oscillating drive, and the conveyor drive.
GE-GB650 handles PCB from 0.2 mm to 3.2 mm. Maximum board size 650 × 650 mm. Conveyor speed 0.5 – 6 m/min.
GE-B650 is a three-brush mid-volume workhorse (4 kW, 400 kg). GE-GB650 is a six-brush high-volume progressive system (28 kW, 2500 kg) for multilayer and heavy-copper lines.
Yes — for the cleanest pre-treatment, pair the GE-GB650 brushing machine with the GE-GBD650 PCB deburring machine downstream to handle drill burr on hole walls.
