1, if it is new Honing Process , how many will be a little rough, this is normal! Can be used to trim flat! 2, depending on what type you are honing rod of a! If you are honing up multiple open then because thimble with each honing wear contact surfaces are not the same, when you remove and then fitted with the last installed if honing not correspond to the position is not the same as it will as a result of the contact surface uneven honing level there is a change! So it is best for each slot in the honing rod well marked, and then the corresponding honing also cook the same label, so each honing installed the same position each time there would not be this problem! 3, if it is a single of the honing honing rod, that is not loaded thimble in place, or junk resisted! If you change the thimble or ground rod (including the same model specifications) ejection time will be a bit uneven, and that is no way! Shuhei had it processed again!
Although the metal processing industry without pressure Honing Process , but there are still such a process requirements. Sunnen honing rigidity developed before the procedure can reduce the undesirable dimensional changes caused by processing . Honing can improve the uniformity of the quality of the workpiece surface , the other trimming process can be produced in micro- cracks. However, only in the honing do not process it as a case of cutting only showing the above-mentioned advantages. In addition to honing grinding surface only slight bulge above the average peak , cutting depth does not exceed several tens of microns . Figure 3 shows the honing can significantly improve the surface quality . Figure 3 on the map is not the honing of the workpiece, its surface was rough serrated The figure is the same after honing surface . After honing the cylinder wall is to increase the contact pressure with the piston . When we compare the before and after contact with the surface brush honing ratio found brush honing surface after honing brush contact rate increased significantly in the absence of excessive resection material or damage the surface quality of the workpiece surface finish of the case raise a processing method . Brush honing the block is similar to a brush . Brush which contains abrasive nylon filament , which contains 40% of the honing material . The abrasive nylon filament can be Al2O3, SiC, BN or diamond , and other abrasives . Honing brush to form massive sales , the same as with conventional honing stone can be installed in a standard combination of honing head, a group of blocks brush honing honing under pressure at 40psi over 20,000 holes.
