Central Manufacturing Facility(CMF) has carried out manufacturing related Research and Development projects in collaboration with industries and Academia. CMTI were pioneers in development of cutting tools for metal cutting operation and have developed many technologies for metal cutting. Some of the recent R&D activities carried out by CMF in the recent years include:

|
|
Cryogenic machining (Cryogenics as a alternative to flood coolant) |
 
|
Supply of Cryogenics such as Liquid Nitrogen (LN2 @ -196 °C) to the cutting zone is one research area that is being explored to improve the process efficiency of difficult to machine materials. Outcomes: Improvement in tool life reported. Subsequent applications found in machining of Tyre treads by Cryo machining for M/s. Ceat Tyres Ltd. |
|
|
Minimum Quantity Lubication(MQL) |
|
A collaborative R&D project carried out at CMTI with University of Arkansas – UARK, USA, to establish, using of MQL for manufacturing and to introduce this technology to the INDIAN manufacturing industry. Outcomes: The test results showed that nanoparticle integrated lubricants significantly reduce the cutting forces by reducing sliding friction between the tool and the work piece, increases Grinding-ratio and surface finish of the work pieces and improve the overall grinding performance in MQL applications compared to that with base fluids and conventional flood lubrication |
Other R&D projects carried out include
- Cutting Force measurements and Analysis for Spheroidal Grey Cast Iron during Turning and Drilling
- High Speed Machining of Stainless Steel
- Machining Technology development for Magnesium alloy, Aerospace components
Product manufacturing department manufactures components of high precision and special purpose applications. Some of the components manufactured in the past include the following
