Micro-drill experimental device 2000 (MDES 2000) can stimulate field conditions, including rock abrasiveness and drillability tests, the diamond bits performance parameters and service life tests and optimization of drilling practice parameter tests and can do some other micro-drilling experimental researches in laboratory. Drilling stimulation work can be made, and the monitoring, collecting and storing the parameters (bit pressure, penetration rate, rotary torque and spindle stroke) can be realized in drilling process with a database of drilling parameters report file being built. This experimental device has a great practical significance for the core drilling research.
