GE-B650 Brushing Grinding Machine

GE-B650 sits in Step 2 · Deburring & Pre-treatment of the PCB production line — right after CNC drilling and before PTH plating. Removes drill burr, dust and oxide, then rinses with DI water for a clean, slightly roughened copper surface that holds dry-film and plating.

GE-B650 FAQ

The GE-B650 is a conveyorised PCB brushing and grinding machine used after CNC drilling to remove drill burr, surface dust and oxide from the copper. It combines oscillating brushing with a grinding station on a 650 mm conveyor.

GE-B650 uses a three-stage brush sequence — 500#, 800#, 300# — that removes heavy oxide, refines the surface, then burnishes. The 800# brush is the workhorse; 300# is the final polish.

GE-B650 handles PCB plate thickness from 0.2 mm to 3.2 mm. For 0.2 – 0.5 mm thin PCB run at 0.5 – 1.5 m/min; for 1 – 3 mm standard PCB run at 2 – 4 m/min.

GE-B650 draws 4 kW from a 380 V / 50 Hz three-phase supply. The grinding motor and the brush motor are each on a separate drive for independent control.

Yes. The GE-B650 has a downstream double spraying rinse station fed with DI water to flush removed oxide and debris off the panel before the next station.

The GE-B650 removes surface burr effectively. For heavy hole-wall burr, pair it with the GE-GBD650 PCB deburring machine downstream.

GE-B650 is the mid-volume workhorse (4 kW, three brushes, 400 kg). GE-GB650 is the high-volume progressive system (28 kW, six progressive brush motors, 2500 kg) for multilayer and heavy-copper PCB lines.
