Bare Engine honing refers to the use of one or more oilstones installed around the honing head, and the oilstone is opened upward along the road by the opening mechanism to press it into the hole wall of the workpiece, thereby generating a certain contact surface. At the same time, the honing head rotates and reciprocates. The parts do not move; or the honing head only rotates and the workpiece reciprocates, thereby realizing MG Roewe Maxus Engine honing.

High processing accuracy: especially for some small and medium-sized through holes, the cylindricality can reach 0.01mm.

Good surface quality: the surface is a cross-net pattern, which is conducive to the storage of lubricating oil and the maintenance of oil film.

Wide processing range: mainly processing various cylindrical holes, through holes, and holes with discontinuities in the axial and radial directions

Strong hole correction ability: The use of MG Roewe maxus engine honing technology can greatly improve the dimensional accuracy of holes and outer circles, and remove small processing allowances. Roundness, straightness, cylindricality and surface roughness.
