Special Purpose Microscope (SPM04) is a specially designed microscope with a high resolution CCD camera to view, instantly photograph & measure exact angle of honing ( Hatch Angle) in honed grey iron cylinder liners used in internal combustion engines. The honing texture consists of two sets of approximately parallel, stochastically placed groves at different angles to the cylinder axis Engine oil consumption. longevity and noxious emissions highly depend on the quality of this grove texture.
Vardhan SPM04 is interfaced with your own computer. The Honing texture image is crystal sharp & can be directly seen on the computer monitor The Image can be saved as a traceable record, exact angle of honing is measured by a user friendly software This novel set up completely replaces the old method of testing the liner surface by fax film.
