I. Features 1, a construction start, automatic repeat, simple, one person can operate several machines, safety, the human body without harm. 2, low cost of consumables, stainless steel needle for grinding material, the service life of 3--5 years. 3 speed, the average primary grinding 4-6 minutes, strong magnetic force, replacement parts quickly, without stopping the machine can be changed abrasive. 4, finished part after grinding, never deformation, no dead ends, no damage to the surface, does not affect accuracy. 5, clean, smooth machine is good, saving sound noise is small. Second, the installation and commissioning 1, when lifting the machine can not squeeze, collisions and excessive vibration. 2, the installation of the machine, just select on a flat concrete floor. 3, the input power should be stable through the air, the safety switch, voltage and the voltage equivalent to the machine, the machine is equipped with variable frequency controller, do not have to have a good grounding. Third, the operation and use 1, through an appeal to install, and then to determine the size of the grinding conditions based on machining parts, material properties, grinding purpose, the production quantity. (1) According to the magnetic polishing machine needle size to choose an amount of primary processing of parts requirements to select the size of the grinding needle (note the presence or absence of blind holes machined parts and slit). (2) the amount of polishing solution based on the requirements of the workpiece and the polishing material properties corresponding to the rotating polishing liquid (slurry, brightener, reference dosage: 1KG part of the standard addition 30-50ML / times). 2, to determine the polishing time of selection should be based on the polishing time to change the shape of machined parts, usually find out the best time trial on the basis of the process. 3, after the processing of parts cleaning, separation of the workpiece and the needle finished processing, machining parts and needle should be washed with water, select the appropriate sub-screen will be separated parts and needle, the other parts should be further cleaned, and then do drying. Fourth, machine installation and use of a machine is a three-phase five-wire system (one zero line, a ground, and the remaining three as FireWire) 2 communicates power, turn on the power switch, voltmeter indicates voltage 380V. 3 energized before timer, set the required grinding time (M: minutes, S: seconds, H: when the unit) and square-up time (at the time the machine is running the way non-adjusted). 4 at runtime by the set time, it will stop automatically after completion, need to continue to work, press the reset button to start the machine again, the process repeats the last action. Fifth, maintain and repair a machine should be placed on the flat and practical ground, the balance must be adjusted. 2 machines on the environment should be dry air, ambient temperature must not exceed 40 degrees.
