Honing hi precision machining process a ni a, a bik takin hole chhungril quality tihsan nan hman a ni. Honing head-a oilstone (honing bar) embedded hmanga workpiece surface chu low-speed grinding a ni a, chu chuan precision sang tak leh surface effects tha tak a nei thei a ni.
Honing principle bulpui ber chu cross mesh formation leh low-speed grinding hman a ni. A bik takin: honing head chu axial direction-ah a inher a, a inher leh a, chu chuan oil lung chu hole wall-ah a press a, intersecting spiral cutting trajectories a siam a, intersection angle chu a tlangpuiin 10℃atanga 70℃inkar a ni Grinding speed hniam (minute khata meter 15-30 vela steel processing ang chi) leh controllable cutting zone temperature (50-150℃) avang hian surface residual stress leh deterioration layer chu nasa takin a tlahniam a ni. Chutih rual chuan high-pressure cutting fluid (kerosene ang chi) hmangin chips te chu silfai a, tihlum a ni bawk.
Honing hian processing range zau tak, surface quality sang tak, leh precision sang tak a nei a. Cylindrical hole, conical hole, etc. diameter 5-500 millimeter emaw a aia lian emaw tan a tha a, thil zawng zawng deuhthaw chu process theih a ni Processing hnua surface roughness chu Ra=0.1~0.012 μ m a thleng thei a, cross mesh pattern a siam thei a, chu chu lubrication atan a tha hle.
