Imported internal grinder operation need to pay attention to several points: 1, imported internal grinder must comply with the safe operation of mechanical cutting procedures. 2, the workpiece before processing, should be based on the workpiece material, hardness, precision, rough grinding and so on, a reasonable choice of the appropriate wheel. 3, change the wheel, according to the safety of grinding wheel operating procedures. You must carefully check the wheel size and line speed meets the requirements, the surface can not be cracked, the sound should be crisp. 4, the installation of grinding wheel, to be balanced test, first empty car test run for 10 minutes, confirm the correct before use. 5, grinding, the first vertical block iron adjust the tight, so that reciprocating sensitivity. People are not allowed to stand on the front, should stand on the side of the wheel. 6, feed, the wheel will not be allowed to touch the workpiece, to leave a gap, slowly feeding, to prevent the sudden burst of force after the wheel accident occurred. 7, the wheel does not leave the workpiece, shall not stop running. Loading and unloading workpieces, measuring precision should be stopped, the wheel back to a safe position to prevent abrasion injury. 8, dry grinding of the workpiece, not suddenly converted to wet mill, to prevent wheel fragmentation. Wet grinding work coolant is interrupted, stop grinding immediately. 9, imported grinder grinding bore, plug gauge or instrument measurement, the wheel should be retreated to a safe position, to be carried out after the wheel stopped. 10, imported grinder grind various cutting tools, splines, keyway, flat body and other intermittent surface work, you can not use automatic feed, the amount of infertility should not be too large. 11, not specifically used face grinding wheel, are not allowed to grind a wider plane, to prevent broken wounding. 12, often change the coolant, to prevent environmental pollution. Grinder is the use of abrasive on the workpiece surface grinding grinding. When inadvertent grinder after prolonged use, simply show some faults, troubleshooting methods are there? 1, intuitive method: that is, the use of human senses pay attention to the appearance of the attack and determine the failure of the attack site. If there is a fault, there is no abnormal sound, spark attack, where the focal blur appears, where the appearance of abnormal heat, and then further to the appearance of failure of each circuit board, which is a basic , The most simple way, but it requires grinding machine maintenance staff have a certain maintenance experience. 2, Hardware prompt function: Indicator lights can identify the fault location. In the centerless grinder hardware circuit board has many lights, which can be roughly identified the location of the fault location. 3, the software prompts: CNC system has self-diagnosis function. In the system operation time, the system can be quickly diagnosed by self-diagnosis program. Once the fault is detected, the indicator light will blink, maintenance can be based on the light to find the fault location grinder. 4, grinder system parameters: system parameters will directly affect the changes in the function of the grinder, and even make the grinder attack failure, the entire centerless grinder can not work. Disturbing the outside world can result in a single parameter change in the memory, which can be checked against grinder parameters when some grotesque fault occurs.
