Project Highlights

Ultra-Precision Micro-machining Centre is a CNC-controlled 5-axes machining centre
that is specially developed for the demands of micro-machining in numerous industries. While
most Machine shops offer 3 or 4-axis milling services, AMTDC-CoE is confident about advanced
5-axes micro-machining capabilities. In combination with the rotary and swiveling unit, the
efficient computer numerical control (CNC) enables the machining of 2.5D, 3D and freeform
surfaces by the use of up to 5 simultaneous axes of motion. According to the selection of ‘tools’
and the process parameters, a wide variety of materials can be machined to the highest

precision of 0-1 micron. The spindle speed can reach up to 50,000 rpm, which allows tools in
the range of 250 micron to 8 mm to be used. The base of the unit is made of cast-iron structure
filled with epoxy concrete, which guarantees the highest long-term thermal and mechanical
stability and effectively eliminates vibration. Together with high precision of the individual
axes, a high precision is ensured for the entire unit. The machine finds huge application in
manufacture of dental and bone implants; instrumentation, electronics, jewelry manufacturing
industry and precision aero- and space industry components. This vertical ultra-precision
machining centre, being developed under this project is designed to match the performance of
similar imported machines at a cost about one-third of the imported variants.

Current Status

The prototype of the Ultra-Precision Micro-Machining Centre is under development at
the industry partner MTAB Engineers, Chennai. The project will be completed by September
2019.
