Steps of On-engine Cylinder Boring for Diesel Generators

Many users may not be familiar with cylinder boring. What is its composition? What are the specific categories? How to use it correctly? Below, Dingbo Power, a professional diesel generator manufacturer, will introduce in detail the steps of on-engine cylinder boring for diesel generator sets.

1.Install the fixing device of the cylinder liner in the adjacent cylinder.

2.Clean the cylinder plane and the bottom of the cylinder liner. If there are debris between the top surface of the cylinder block and the cylinder liner, it will cause the cylinder liner to tilt, making the cylinder axis not perpendicular to the cylinder plane, which will affect the repair quality.

3.Place the cylinder boring machine on the cylinder block, align it with the cylinder to be bored, and use the fixing device of the boring machine to initially fix the boring machine.

4.Select a set of corresponding centering fingers according to the cylinder diameter, and turn the centering finger knob to retract them.

5.Lower the boring bar to the lower part of the cylinder using the lifting handle, turn the centering finger knob to extend the fingers to the cylinder wall, thereby pushing the boring bar to center it in the cylinder. For more accurate centering, loosen the centering knob, rotate the boring bar to another angle, center it again, and gently turn the cylinder boring machine to fix it completely. Retract the centering fingers and lift the boring machine.

If the cylinder is sleeved, it can also be centered at the maximum diameter. The advantage of this method is that the boring amount is minimized, while the disadvantage is that the cylinder centerline will shift after honing, which affects the assembly accuracy of internal combustion engine parts to a certain extent. The above preparation work is very important when boring cylinders. However, due to its simple operation, it is often overlooked, resulting in insufficient fixation. During boring, the boring tool is loaded, causing the boring machine to move and damage the cylinder. Therefore, in daily work, we must strengthen our sense of responsibility and carefully and meticulously complete the above work.

6.Select a suitable boring tool holder according to the cylinder diameter, install it on the push frame. Then wipe the tool holder and the hole, and install the tool holder into the tool holder hole.

7.Adjust using the micrometer on the cylinder boring machine. Adjusting the boring tool is the most important part of the work. Sometimes, due to improper adjustment, the cylinder may exceed the selected repair size, and thus it is necessary to increase the repair size and re-sleeve the over-bored cylinder. Therefore, during adjustment, we must have a serious and responsible attitude and meticulous spirit, be patient and careful, and check repeatedly, especially for the final cut, which must be extremely accurate.
