The characteristic of stainless steel grinding reachs the choice essentials of dosage

The choice of the characteristic of stainless steel grinding and dosage essentials

1, stainless steel grinding characteristic:
(1) grinding muscularity, grinding temperature is high, treatment expresses easy burn;
(2) machines sclerotic trend serious;
(3) worries bit easy conglutinate is on emery wheel, make emery wheel hole jams;
(; of cut of occurrence grinding of 4) workpiece surface
(5) workpiece allows changeful entity.
2, the choice of grinding dosage principle:
(The choice: of Vs of speed of 1) emery wheel? Still Gou Gu Ao Zhixing has enough Zhang of the grave that read Nai angries when showing? grinding stainless steel, should choose Vs of taller emery wheel speed, but, make as a result of the meeting when emery wheel rate is high emery wheel jams, lose cutting ability instead, and incidental grinding burn, easy cut machines the surface, because speed of careful choice emery wheel answers when this grinding stainless steel. Carry out a proof, the emery wheel speed of grinding stainless steel with exceeding 25m/s more appropriate.
(The choice: of Vw of 2) workpiece speed? W of Qu of ぜ  Yu should change as Vs of emery wheel speed, basic principle is Vs low, vw is inferior also;vs is tall, vw also subsequently heighten, such doing can make area of the cut that cut bits keeps basically changeless. Vs and Vw change into scale, can make grinding cut decreases. General, the speed of workpiece speed and emery wheel is optional inside 1/60~1/100 limits.
(The choice: of Ap of 3) grinding deepness? When Sun of suddenly of flatter ハ Da is worth benzyl of ⑺ of the hot toad that ask a source to wish to knock at Mou Mu to deepness of bright? grinding is less than or be equal to 0.01mm, emery wheel is easy conglutinate jams, appear easily the phenomenon such as burn and cut. Its reason is arenaceous bead has certain round horn radius, when grinding deepness too hour, arenaceous bead is cut do not enter matrix, and in apparently delimit brush extruding, cause grinding force and grinding hot heighten, cut bits easy conglutinate to jam emery wheel, reduced capacity of emery wheel cutting, cause workpiece face cut. 0.02~0.05mm is taken commonly when kibble, 0.01mm left and right sides is taken commonly when essence of life is ground.
(The choice: of 4) feed? Word of   earnestly is stupefied Qu of Ji of Ao Zhi of domestic fall from the sky will calculate. Outside round grinding stainless steel, the feed of kibble is desirable (1/4~1/6)B, the feed that essence of life grinds is desirable (1/8~1/10)B. Take when grinding deepness is big among them lesser value, grinding deepness hour is taken among them greater value. When workpiece tigidity is good, feed can increase appropriately. Grinding is long and thin when kind of workpiece and thin wall workpiece, to prevent to be out of shape, can use big feed and small grinding deepness to undertake grinding. Inside when round grinding, the feed of kibble is desirable (1/3~1/4)B, the feed that essence of life grinds is desirable (1/6~1/8)B. When grinding shallow aperture, take among them greater value, when grinding deep aperture, take among them lesser value. When the treatment precision when workpiece and demand of exterior surface roughness are higher, feed should be reduced appropriately.
