Some key things to pay attention to when using a diamond reamer for rock coring in mining:
Rock Type - Carefully select a reamer design suited to the anticipated lithology, such as segmented for hard rock or impregnated for mixed geology.
Fluid System - Ensure adequate fluid supply and pressure to effectively flush cuttings away from the bit face and transport debris from the hole.
Wear Monitoring - Check reamer frequently for wear flat spots and reduce pressure/replace it if penetration rates decline substantially.
Cutter Dressing - Dress the bit regularly to maintain an aggressive cutting structure and expose fresh diamonds.
Impact Protection - Use appropriate guards/deflectors to shield the reamer from fractured zones that could cause damage.
Rig Control - Maintain optimal rotational torque and thrust/pullback pressures advised for the rock and reamer.
Hole Cleaning - Periodically backream or circulate to fully evacuate fines and cuttings plugs impairing drilling.
Health & Safety - Employ proper dust suppression, enclosed cabins, hoisting gear, lockout procedures as dictated by regulations.
Record Keeping - Document drilling parameters, performance metrics and geological observations to optimize subsequent reaming programs.
Maintenance - Inspect and service the reamer and rig daily per manufacturer instructions to minimize downtime on site.
Proper handling, operation within ratings, and diligent attention to these factors helps maximize reamer life and ensure consistent, safe and efficient coring runs.

Q&A:
1,Are shorter, more frequent reaming rounds better than full-shift runs?
For some applications, it may be preferable to conduct multiple short duration reaming cycles per shift using multiple tools in rotation rather than running single reamers continuously until dull. This balances wear across the available systems.
2,Do reaming simulations or 3D part designs shorten product development?
Yes, virtual modeling and dynamic simulations during reamer design can validate concepts against modeled stresses without physical prototypes. They efficiently test reamer-rock interaction under various cutting conditions, shortening physical test work and getting new tools to market faster.
3,Can reaming performance data be collected, monitored and analyzed?
Instrumenting reamers provides valuable insights by transmitting downhole parameters in real-time. Telemetry networks record penetration rates, torque, vibrations and cutter temperatures. Analytics identify correlations between performance and factors like hardness, fluid properties or dressing schedules to optimize reaming programs.
4,Do computer aided designs facilitate rapid prototyping of new reamers?
Absolutely. 3D CAD models allow rapid evaluation of new cutter layouts, materials selections or structural tweaks through computer modeling before desktop manufacturing techniques like CNC machining or additive processes produce evaluation prototypes in hours/days rather than the weeks required for conventional manufacture. This shortens design-test feedback loops significantly.
5,How successful has 3D printing technology been for manufacturing reamers?
Initial applications involved pilot production of consumable components. Now entire reamer heads, cones and frames are being additively manufactured as standard products. Benefits include design complexity, part consolidation, physical property tailoring and on-demand local production avoiding long lead times - transforming how customized solutions reach challenging job sites.
