DESCRIPTION
The used SUNNEN CHV-31A pneumatic cylinder honing machine is a precision machine tool for finishing cylinder bores in small and medium displacement engine blocks.
The manual mandrel expansion system allows direct control of the contact pressure between the abrasives and the cylinder wall, enabling adjustment of the stock removal rate and working on different diameters with the same tooling.
The pneumatic drive guarantees constant rotation speed regardless of the applied load, eliminating speed variations that could compromise the quality of the surface crosshatch pattern.
