High Precision Quartz and ceramic Machining
India’s Leading Specialist in High-Precision Quartz & Ceramic Machining
Ramtech Manufacturing Industries stands at the forefront of advanced precision machining in India, with a rare and distinguished capability—the Ultrasonic 20 Linear DMG MORI 5-Axes Machining Center. We are proud to be the only company in India honored to possess this state-of-the-art technology, enabling us to machine extremely hard, brittle materials such as quartz, ceramics, and technical glass with unmatched accuracy and surface integrity.
Excellence in Aerospace-Grade Components
Our facility is uniquely equipped to produce high-precision quartz resonators and ceramic components used in critical aerospace and space applications, including those supplied to premier space research organizations like ISRO. These components demand ultra-tight tolerances, perfect geometries, and surface finishes free from micro-cracks or thermal damage—standards we consistently achieve through ultrasonic machining technology.
Why Ultrasonic 20 Linear?
Contactless Material Removal
Reduces stress and eliminates microfractures in brittle materials.
Nanometer-Level Accuracy
Essential for resonators, frequency stabilizers, insulators, and optical components.

Hemispherical Resonator Gyroscope
Ramtech experience in machining of fused silica optical Resonator Hemispherical Resonator Gyroscope (HRG),
HRG is unique in its simplicity and its ability to sense very small angular motions and is a compact, low noise, high performance angular rate or rotation sensor. An HRG is made using a thin solid-state hemispherical shell, anchored by a thick stem. This shell is driven to a flexural resonance by electrostatic forces generated by electrodes which are deposited directly onto separate fused-quartz structures that surround the shell. The gyroscopic effect is obtained from the inertial property of the flexural standing waves.
