Usha is capable of producing parts that have sub-micron dimensional and geometric tolerances – Usha regularly makes parts that are tolerated within 0.001mm or one millionth of a meter with measuring capabilities within 100 nanometers! And these parts have near-perfect form geometries like roundness and cylindricity within fraction of microns!

Parts manufactured to such close tolerances must be super-finished to extremely fine surface finishes. Usha is normally capable of generating turned surfaces with a finish of Ra 0.50 microns and ground / honed / lapped / super-finished surfaces with a finish of Ra 0.05 microns.

Usha manufactures parts in various heat-treatable alloy steels including through hardening ball bearing steels, high-speed steels, stainless steels, case-hardening steels, nitriding steels and many more. All these steels are procured from the most reputed domestic and international steel mills with necessary test certificates and subsequently tested by Usha.

The core strength of Usha comes from an excellent heat-treatment facility for steels supported by a metallurgical laboratory which is capable of producing the most consistent quality of heat-treated parts.

Usha’s technical capabilities are reflected in its extensive manufacturing, heat-treatment, inspection and product testing facilities. In the following pages you will discover how Usha with its rich experience and technical expertise in precision component manufacturing
