Aicmiú Táirgí Snasú

Mar is eol dúinn go léir, tá go leor tionscail phróiseála agus déantúsaíochta miotail agus neamh-mhiotail doscartha ón bpróiseas snasta. Ós rud é go bhfuil ceanglais an-bheag ag snasta maidir le liúntas meaisínithe, go háirithe le haghaidh próiseáil táirgí le bailchríoch speisialta, ba cheart táirgí snasta a roghnú, ionas go bhfeabhsófar an éifeachtúlacht oibre a oiread agus is féidir nuair a chomhlíonann an dromchla na ceanglais. Is iad seo a leanas na táirgí snasta a úsáidtear go coitianta:

1. Gaineamh snasta: úsáidtear go forleathan é le haghaidh snasta páirteanna crua-earraí, plátaí, gabhálais meicniúla, táirgí plaisteacha, ábhair neamh-mhiotalacha agus tionscail eile. De réir a ábhar, cuimsíonn sé gaineamh alúmana, gaineamh corundum donn, emery, gaineamh corundum dubh, gaineamh corundum bán, gaineamh cruach, gaineamh chomhdhúile sileacain glas Bead gloine (ar a dtugtar gaineamh gloine freisin), etc. i measc na n-ábhar seo, éilíonn cuid acu go bhfuil ní mór na cáithníní scríobacha a bheith cruinn, mar shampla coirníní gloine, agus éilíonn daoine eile gur chóir go mbeadh na cáithníní scríobacha géar, mar shampla emery. Dá bhrí sin, ba cheart é seo a chinneadh de réir riachtanais éifeacht snasta an táirge. Tá éifeachtaí próiseála go hiomlán difriúil ag an scríobach snasta céanna mar gheall ar mhéideanna éagsúla na gcáithníní, ó garbh go fíneáil, mar shampla Uimh. 24, Uimh. 36 agus Uimh. 60 , 80, 100, 120, 150, 180' , 220, 280, 320, 400, 600, 800, 1000, agus os cionn 1000. Sa phróiseas oibríochta iarbhír, déantar an chuid is mó díobh a phróiseáil trí phléascadh gaineamh, nó cuireann siad an gaineamh go díreach ar eitleán an phíosa oibre atá le próiseáil agus snas é le cuimilte.

2. Polishing wheel: soft binders such as elastic resin and rubber can be used to make the polishing sand into a specific shape through the mold, or the abrasive can be directly attached to other substrates, such as sponge wheel, wool wheel, wool felt, hemp wheel, cloth wheel, sandpaper, hundred page wheel, thousand page wheel, etc. in addition, there are paste products, such as diamond grinding paste.

3. Polishing oilstone: generally divided into natural oilstone and artificial abrasive oilstone. Natural oilstone is formed by long-term deposition in nature, so its quantity is limited. In most cases, artificial abrasive oilstone can replace natural oilstone, even with better effect, which is more conducive to long-term production. Therefore, it is very helpful to distinguish the materials for the production of oilstone. The abrasives include carbides such as black silicon carbide, green silicon carbide and boron carbide, corundum such as brown corundum, white corundum, red corundum and single crystal corundum, as well as superhard materials such as diamond and cubic boron nitride. Generally, the oilstone used for polishing is relatively fine, including 600, 800, 1000, 1200, 1500, 2000 and 3000. The finer the particle size is, the brighter the polishing effect is. In terms of bonding agent, ceramic bonding agent, resin bonding agent, rubber bonding agent and metal bonding agent can also be selected.
