The coolant delivery system will be employed to complement and enhance part of aphysical demonstrator, i.e. facilities created as part of the ESIF project, which will be used to facilitate/supportthe take-up of high impact manufacturing technologies by SMEs in the West Midlands region. In this context, thecryogenic coolant delivery system will be used in tandem with various advanced machining centres to developnew applications in collaboration with technology providers and undertake feasibility studies and pilot projects toaddress the specific requirements of local SMEs. The cryogenic coolant delivery system should be capable of supplying extremely low temperature media in thedry condition in order to substantially cool / remove heat from the cutting zone when machining (in particularmilling and drilling) a range of workpiece materials including hard/brittle/abrasive materials such as ceramics,hardened alloys and composites. It is expected that the heat removal capability of the cryogenic coolant willsignificantly exceed that of conventional high pressure cutting fluid environments. The system should besufficiently flexible to enable easy connection to different machining centres. It should also be capable ofsupplying the cryogenic coolant both externally as well as internally through the spindle / tool. In addition to thecryogenic media, it would be desirable for the system to also be capable of delivering a stream of oil dropletstogether with the cryogenic coolant in order to improve lubrication at the tool chip interface. Specifications: - Directed / targeted delivery of dry, cryogenic media to cutting zone in various machining processes inparticular milling and drilling operations. - Capability for delivering cryogenic coolant both externally and internally through the tool / spindle of machinetool. - Ability to significantly reduce tool / workpiece temperatures when machining compared to conventional highpressure cutting fluid systems. - Equipment can be easily be connected / disconnected / reconnected to different machine tools. - Control and monitoring of cryogenic gas delivery (e.g. pressure etc.) during operation. - Fully CE compliant. 3 / 4 - Well defined and agreed workflow with time line from the purchase order through factory acceptance tests tothe site acceptance tests and training. ### Optional component technologies - Capability for delivering low volume of oil based fluid with the cryogenic stream to improve lubrication at cutzone. This project is being advertised in OJEU and is below the EU threshold spend. The time-scale which applies to OJEU will not apply in this project. Standstill period will be 10 days.
