Precision Surface Milling

High-accuracy face milling and surface milling of large components requiring flatness, parallelism and surface finish specifications.

Service Overview

Precision surface milling is one of DHANRAJ Engineering's core strengths. Our SANCO double column machining centre delivers outstanding flatness and surface finish across wide component faces — a critical requirement for machine tool bedways, structural faces and mating surfaces.

We achieve tight flatness and surface roughness specifications using high-quality carbide face mills. Our rigidity advantage ensures consistent cut depth across the full face width, preventing waviness that commonly affects lighter machining centres.
