After the angle grinding machine was return, feed mechanism 4 was sent general each 2-7 millimeter of sending according to default feed length moment.
Feed mechanism 4 is carried out the instruction that the automatically controlled device 7 of micro computer sends, driving feeding reductor 42 by feeding motor 41 starts working, roll wheel 431 motions by the active-feeding that is connected with feeding reductor 42, roll wheel 431 at active-feeding, driven feeding is rolled under wheel 432, the synergy of elastic press wheel 433, carry stably test with being cut rod iron 8 to tested cutoff wheel 11 belows, test can be adjusted by the automatically controlled device 7 of micro computer according to test is required with the delivered length that is cut rod iron 8.
Namely begin the second cutter cutting test after feeding puts in place, later each cutting test all is smart-cut, and namely the speed initial value in regulation enters cutter.During moment values surpass to be set in the cutting process moment intermediate value, angle grinding machine 12 feeding that just reduces speed now; Moment values just begins the speedup feeding less than the moment intermediate value hour angle grinding machine 12 of setting in the cutting process.So come and go and change, until moment values hour, assert that test of this test cutting is cut off with being cut rod iron 8.Repeat afterwards cutting experiment, when reaching the cutting times of setting, termination test, the angle grinding machine is got back to initial position, and the automatically controlled device 7 of micro computer cuts off the power supply of angle grinding machine 12 and dedusting mechanism 6.
The dust that produces in the process of the test enters tornado dust collector by tornadotron 621 by the air inlet 626 that is communicated with top box, and the tornado dust collector High Rotation Speed produces centrifugal force, and dust and particle are in the periphery, and central authorities are net air.Exhaust outlet 625 is got outside the net air discharge machine of central authorities.Peripheral dust laden air is collected in the wind sheltering stifled 624 by dust-collecting pipe 623 by taper dust hopper 622 by the gravity of self, and test is opened wind sheltering stifled 624 later and taken out dust.
After cutoff wheel performance test machine comes to a complete stop, open the machine upper chamber door, unload and test with remaining cutoff wheel 11.Measure the diameter of residue cutoff wheel 11, and this diameter value is input to the automatically controlled device 7 of micro computer.At this moment the touch display screen of the automatically controlled device 7 of micro computer can demonstrate following test figure: actual cutting times, average cutting speed, clipping time, cutting ratio and average cutting force square.
Average cutting speed is larger, clipping time is shorter, the cutting ratio is larger, it is less on average to cut moment, and the cutting ability of expression cutoff wheel is better.
