Study on the Control and Test of High Precision Honing Machine for Injection Nozzle
Because of the high precision in roundness, straightness and roughness, it is very difficult to machining the inner surface of injection nozzle. Honing machine is the main equipment for machining the injection nozzle. The key honing control techniques and honing test for injection nozzle on the developed high precision vertical honing machine are analyzed. The quantitative expansion，which is one of the most important feeding styles in honing process, is discussed in detail. Some machining tests on the developed honing machine are made and the work pieces of injection nozzles with inner surface Φ11mm are honed successfully with roundness tolerance less than 0.4μm, straightness tolerance less than 1μm and roughness tolerance less than 0.04μm.
