Micromachining facility at CMTI with its state of the art infrastructure and expertise promotes the benefit of micromachining and ultra-precision technology for manufacture of micro-components to the Indian industries through consultancy, services and training. Precision Manufacturing & Process Engineering group focuses particularly in development of products indigenisation and fabrication services of high precision parts.
PMPE group has executed many service projects towards development of micro components indigenously. Developed high precision components for Aerospace, Defence, Biomedical and Automobile parts that require precision manufacturing technologies comprising micro feature sizes and dimensional tolerances less than 5µm.Micro components and features ranging from 5 microns to 2-3 mm and dimensional accuracies from 1 micron to 10 microns have been developed for many applications for the components like micro needles, micro channels, micro fuel injection parts, sensors, biomedical parts etc,. Components like Hyperbolic Feed Rollers for automobile industries, breathing regulators components having low feature sizes and 100% quality acceptance criterion for bio medical application, fuel injector components and gyroscopic flexural components for aerospace industries are being manufactured and supplied to the user industries.
