Typical application of abrasive nylon brush in automobile engine industry_FAQ

The engine is the heart of the car. The tiny burrs left after machining have an impact on the life and overall performance of the engine, which has become increasingly prominent with the improvement of product quality. In the past few years, the European, American, and Japanese automobile manufacturing industries have had deburring processes on their engine parts production lines, using a variety of special equipment and nylon brushes containing abrasive filaments to achieve a burr-free effect. A. Automobile engine cylinder head production line: (1) After the end face of the cylinder head is finished milling, use a disc brush to remove the burrs at the intersection of the plane and the complicated grooves, grooves and holes, and the sharp edges are trimmed into arcs. After the cylinder head camshaft seat hole is finely bored, use the hole brush to remove the burrs. (2) Car engine camshaft production line: After the camshaft is heat treated, use brush wheels to clean oxide scale and burrs. (3) Car engine cylinder block production line: Use hole brushes to clean the main and auxiliary oil holes. Install a strip brush on the honing head to clean the crankshaft hole burrs. (4) Car engine crankshaft production line: Clean the oil holes with a hole brush of about Φ6mm. (5) Car engine connecting rod production line: Use Φ44mm small wheel brush to remove burrs. B. Use on other auto parts (1) Transmission: Use a brush to clean the burrs and sharp edges of the valve body, and use a hole brush to clean the burrs and sharp edges of the valve body. (2) In the production of automobile distribution pumps, oil pump nozzles and other parts, there is an abrasive-containing nylon brush deburring process. C. In motorcycle engines, carburetors and other parts, use an abrasive nylon brush to remove burrs on the shell, holes, threads, etc. D. Hydraulic parts and pneumatic components industry: With the upgrading of host products, the quality of hydraulic parts (hydraulic pumps, hydraulic cylinders, hydraulic valves, hydraulic motors, etc.) and pneumatic components (valves, cylinders, air source components, etc.) Increasingly demanding. Compared with imported parts, the main problem lies in the finishing process (small burrs left after machining). Developed countries use a variety of special equipment and abrasive nylon brushes in the production of hydraulic and pneumatic components to remove burrs, Finishing processing. E. Compressor industry: automotive air-conditioning compressors, air compressors, refrigerator compressor parts processing.
