JA-700 Sandblasting Machine Chinelatto - Professional Parts Cleaning

The sandblasting machine is used to clean engine parts removing rust, old paint, burnt oil and oxidation. It's essential in machine shops to prepare components before machining, ensuring clean finish. The JA-700 Sandblaster handles parts up to 27.6x27.6 inches (700x700mm), ideal for cylinder heads, small blocks, pistons and connecting rods. Sandblasting removes impurities that harm paint and treatment adhesion, being indispensable in any professional machine shop.

The JA-700 sandblaster has internal capacity of 27.6x27.6 inches (700x700mm) and height of 23.6 inches (600mm), handling most engine parts. It accepts cylinder heads from small and medium cars, motorcycle blocks, manifolds, oil pans and internal components like pistons and connecting rods. The 3/4HP motor ensures sufficient pressure for efficient cleaning. The compact dimensions of 2.3x2.3x4.9 ft (0.7x0.7x1.5m) allow installation in small shops, but with professional capacity for medium-sized parts.

Yes, the sandblaster works perfectly on car and motorcycle parts. For motorcycles, it cleans block, cylinder head, cylinders and crankcase without problem. On cars, it works for 4-cylinder heads, manifolds, pumps and smaller parts. The JA-700 has internal height of 23.6 inches (600mm), sufficient for most automotive cylinder heads. The 8.0mm carbide nozzle and 0.13 inch (3.2mm) air injector ensure precise sandblasting on both delicate motorcycle parts and more robust car components.

The sandblaster removes heavy oxidation, paint and rust using air pressure and abrasive, ideal for very dirty parts. The parts washer uses heated solvent, better for oil and grease, but doesn't remove rust. The JA-700 sandblaster is more aggressive, preparing surfaces for painting and welding. The parts washer is gentler, preserving original finishes. In practice, the sandblaster is indispensable for complete restoration, while the parts washer serves for routine maintenance cleaning.

The process uses compressed air (20 cfm) mixed with abrasive sand, expelled through the carbide nozzle against the part. The pressure removes oxidation, paint and impurities from the metal surface. In the JA-700, you place the part in the closed cabinet, wear the integrated gloves and direct the blast. The 3/4HP motor aspirates the used abrasive, recycling in the chamber. The result is clean and rough surface, ideal for receiving paint, welding or surface treatments.

Basic maintenance includes changing the carbide nozzle when worn (loses efficiency), cleaning suction system filters and checking cabinet seals. Change the abrasive sand when it loses cutting power. Lubricate the motor according to manual and check electrical connections. The JA-700 weighs 187 lb (85kg), facilitating movement for cleaning. With moderate use in machine shop, the machine lasts many years. The important thing is using adequate compressor (20 cfm) and keeping the cabinet well sealed.
