NANOFINISH technology consists of Superfinishing/ Microfinishing/ Lapping process for generating surface finish that can only be measured in Nanometers.

NANOFINISH range of machines use mainly Film Backed Abrasives with Grind Master NANOTouch Contact Tooling to provide reliable and high performance solutions to a wide variety of components ranging from Engine Parts to Rotogravure Cylinders. NANOFINISH Product Range makes use of Superfinishing & Microfinishing Technology

1. Superfinishing Technology:

It is line contact type method in which Film Backed Abrasives used with NANOTouch ROLL (Wheel) Backing is oscillated against the jobs which are either held between Centre or on Rollers (Centerless) provides surface finish improvement without damaging geometry, achieving Up to Ra 0.05


2. Microfinishing Technology:

It is surface contact type method in which Film Backed Abrasives are used with Various Contact Tooling such as NANOTouch STIFF (for Journals), NANOTouch FLEX (for Lobes), NANOTouch PLANAR
(For Faces).

In most cases the workpiece is oscillated between Centers. Apart from achieving Surface finish requirements, the process also achieves improvement in geometrical parameters such as roundness.

Customized Variations of NANOFINISH Technology such as GSF (Geometry – Size – Finish) are able to achieve multiple parameters in the same process with Advanced Size Control Technology.

ALL NANOFINISH Technologies ensure proper lubrication characteristics which results in extended products life along with elimination of noise & vibration.
