Cylindrical drilling on a CNC engine block machining center
In the engine block, the pistons move in the cylinders. Over time, due to movement, the cylinders may crack or wear out due to material defects, under-design, overload due to tuning, improper lubrication...
In such cases, cylinder drilling is the best solution. We have several options for cylinder renewal. We drill out the cylinder to a larger diameter, thus removing the defective surface, and then install pistons of a correct size in the block. Or we machine the cylinder to such a radius that we can press a cylinder bushing into it, so a completely new, perfect surface is created and we can use the basic size pistons again.
Cylinder drilling is performed using CNC technology. In engine restoration work, cylinder drilling must be followed by a honing process, so that the cylinder wall has a special surface when honed, which helps to maintain compression, and at the same time provides adequate lubrication for the sidewall of the piston.
