1. Bare Engine have high processing accuracy: especially some small and medium-sized through holes, the cylindricality can reach 0.001 mm.

2. Bare Engine have good surface quality: the surface is cross-netted, which is conducive to the storage of lubricating oil and the maintenance of oil film.

3. Isuzu Engine have a wide processing range: mainly processing various cylindrical holes: through holes, axial and radial intermittent holes

4. Bare Engine reduce cutting allowances.

5. Strong hole correction ability: By eliminating small processing allowances, the dimensional accuracy, roundness, straightness, cylindricality and surface roughness of the holes and outer circles of Bare Engine can be greatly improved.
