LUBRICATION SYSTEM IN CNC MACHINE LINEAR GUIDE WAYS FOR PRECISE MACHINING AND LESS OIL CONSUMPTION

摘要

The present invention relates to a lubrication system in CNC machine linear guide ways for more precise machining and less oil consumption. The system includes: a) at least four thermocouples Tcpl_A, Tcpl_B, Tcpl_C, Tcpl_C embedded in linear guide of X-axis and Z- axis of CNC machine for temperature measurement; b) lubrication unit for discharging accurate amounts of oil or lubricant at predetermined intervals; c) lubrication control unit (LCU) with several modules for electrical circuit system; and d) program software for facilitating data acquisition, digital or analog input/output, data analysis, and for monitoring output of the lubrication system; wherein the lubrication system is capable of simultaneously monitoring real time current and temperature of the machine.
