Rotary Table Shot Blasting Machine QJ3512–QJ3525 | Jinwo, Qingdao, China

Jinwo's Rotary Table Shot Blasting Machine cleans small and medium-sized workpieces in batches by turning them on a rotating table while blast wheels throw steel shot at the surface. It removes sand, oxide scale and other residues, and can also strengthen the surface.

It suits flat, thin-walled and impact-sensitive parts that would be damaged in a tumble blaster, such as connecting rods, gears, diaphragm springs, discs, rings and covers. Frequency-controlled blast wheels and a table turning at constant speed give even coverage, with a stated shot coverage of over 98%. The machine is offered in three sizes, QJ3512, QJ3516 and QJ3525, and can be built with single, double or multi-station tables.

Frequently Asked Questions

• What size parts can it clean? Cleaning size ranges from 300×130×120 mm on the QJ3512 to 1,000×800×400 mm on the QJ3525, with table loads of 200–1,000 kg.
• Can it be built with more than one station? Yes, the rotary table can be designed with single, double or multi-station layouts for easier loading.
• Will it damage delicate parts? Parts rotate with the table rather than tumbling, so there is no collision or deformation, which suits thin-walled and fragile workpieces.
• What should I send for a quotation? Send the workpiece type, dimensions and weight, material, the surface condition to be removed, the finish required, batch size or output target, and the number of stations wanted.
