Inventor: C M Myers Priority requested Win June 2, 1960 (USA) In the operation of grinding and polishing machines, e.g. for .sliping and polishing 1 = skin fitted with padded contact wheel and stipule partCovered polishing tape, which moves with dor speed, it is edge to completely Vata a new and rigid polishing tape Tried kerosene or similar substances will soften the tape, whereby. . The narrow temperature and solidification properties of tallow, etc., make these usable for the spirit. The stoned tallow makes it easy for workers to adjust the working depth of the dipping surface of the belt by appropriately adjusting the amount of tallow that pales the surface of the belt. However, the tallow also has certain undesirable properties, especially since the tallow has absorbed large amounts of powdered abrasive and metal particles and thereby forms mainly solid material, which is pressed into the spaces between the abrasive particles on the surface in the form of a metal or less hard layer, which results in , that the band becomes stiff and loses its. the joint effect. Since a strip on it has been partially damaged by pressing in material, it is usually necessary to either stop the polisher and clean the strip, to replace the strip with a new Admit or to apply a higher pressure to the workpiece to be polished. The use of a higher pressure immediately means a non-obscure advantage: lining of the band's dipping surface and possible damage to the workpiece as a result of the greater friction saint further an unfavorable wear and tear of the belt's backing material, thereby reducing the belt's effective fit1ngng.

Sasom visat i fig. 2 bildar polermedlet, da det paforts slippartiklarna 24, ett enda Amutjockt skikt pa partildarnas 21 6vre yta. I fig. 3 har antagits, att det pa ytan befintliga rued-let, som vanligtvis bestar uteslutande av talg eller talgliknande eller fettartade aranen, torrt och upptagit en massa sma slip- och metallpartiktar, varigenom det bildats en forhallandevis hard produkt, som packats runt slipkornen 24, sasom visat rid 26. As shown in Fig. 2, when the abrasive particles 24 are applied to the abrasive particles 24, a single Amut-thick layer forms on the upper surface of the partitions 21. In Fig. 3, it has been assumed that the surface-present window, which usually consists exclusively of tallow or tallow-like or greasy arane, has dried and taken up a lot of small abrasive and metal particles, thereby forming a relatively hard product which is packed around grinding grains 24, as shown in ride 26.
Vid anvandande av slip- och polermedlet for slipning och polering av metallforemal i en polermaskin av bandtyp, sasom visat i fig. 1, overdrages bandet 7 forst med ,ett skikt av polermedlet genom att delta pafores bandets slipyta via dysan 17 fran avgivningsanordningen 16, van i medlet forvaras och standigt °mores medelst onnoraren 19, sa att det alltid bildar en likforrnig och homogen blandning. Till f6ljd av bandets 7 stora hastighet, som norm-alt uppgar till c:a 1790-2700 m/ min beroende pa polermaskinen, storlek has kontakthjulet 4 osv. avkastas snabbt eventuellt overskott av medial fran bandets yta och slipytan tackes harigenom med ett jfimnt och tunt skikt av medlet, sasom antytt I forstorad skala i fig. 2. Harefter Unser arbetaren att det sker en forangning eller avgang av en del av det mycket flyktiga och snabbt verkande us- ningsmedlet for smorjmedlet, vilken forangfling Mrsiggar tamlige•n snabbt som en foljd av bandets snabba rOrelse, till dess att konsistensen hos den pa slipytan kvarblivna delen av medlet Or den lampliga f6r det speciella slip- och polermedlet. Slipningen och poleringen kan sedan begynna och efter kort lid borjar det harda smorjrnedlet att stelna och upptaga delar av slippulver och metallpulver i .samma man som losningsmedlet fortsfitter att fOrangas. SO. snarl bandet blivit srautsigt eller fatt slipytan inh8ljd med en blandning av hart smorjmedel, slippulver och metallpulver, se fig. 3, paverkar arbetaren avgivnings- anordningen 16 ochytterligare Mang- der av medlet pa bandets 7 yta alit under del att poleringen fortsatter. Genom paforingen av sa.da:aa ytterligare mingder av medlet pa bandets 7 yta losgores eller upploses mer eller mindre momentant del inpackade eller smutsiga, harda smorjmedelet, och delta bortstotes darefter fran bandet genom centrifugalkraften, och poleringen fortsfitter pO. °van beskrivet sat. Del an klart att det ovan beskrivna Mrfarand:et vid slipning och poleriing av metallforemal icke beh5ver utf5ras med anvandande an den beskrivna automatiska a.pparaturen utan Oxen kan ske manuellt genom begagnande av slipmedlet pa slipytan av bruk- • liga handdrivna •sliporgan. When using the abrasive and polishing agent for grinding and polishing metal molds in a belt-type polishing machine, as shown in Fig. 1, the belt 7 is first coated with a layer of the polishing agent by participating in the sanding surface of the belt via the nozzle 17 from the dispenser 16, in the agent is stored and constantly ° mores by means of onnoraren 19, so that it always forms a uniform and homogeneous mixture. Due to the belt's 7 large speed, which normally amounts to about 1790-2700 m / min depending on the polishing machine, the size of the contact wheel 4, etc. any excess of the medial from the belt surface is quickly returned and the grinding surface is thereby thanked with a smooth and thin layer of the agent, as indicated on an enlarged scale in Fig. 2. fast-acting lubricant for the lubricant, which evaporates rather quickly as a result of the rapid movement of the belt, until the consistency of the part of the agent remaining on the grinding surface is suitable for the particular abrasive and polishing agent. The grinding and polishing can then begin and after a short time the hard lubricant begins to solidify and absorb parts of the abrasive powder and metal powder in the same manner as the release agent continues to evaporate. SO. If the belt has become dirty or the grinding surface has been covered with a mixture of hard lubricant, grinding powder and metal powder, see Fig. 3, the worker affects the dispensing device 16 and further. By the application of the following: aa further amounts of the agent on the surface of the belt 7 are loosened or dissolved more or less momentarily part wrapped or dirty, hard lubricant, and delta is then repelled from the belt by the centrifugal force, and the polishing continues pO. ° van described sat. It is clear that the procedure described above for grinding and polishing metal objects does not have to be carried out using the described automatic equipment, but the Taurus can be done manually by using the abrasive on the grinding surface of conventional hand-operated grinding means.
Det framga'r av det ovan anfOrda, all man genom uppfinningen imdanrojer de ink& ningsvis amtalade olagenheterna i saraband med tidigare anvanda medel for polening av metaller. Dessa olagenheter avhjfilpas genom begagnande av medlet enligt uppfjnningen och av det angivna sattet for slipning och pole7 ring av metaller. Det torde vidare vara klart, att upprinningen har de angivna fordelarna jamfort med de hittills kanda metodema.- ShitTigen shall papekas, att uppfinningen icke fir begransad till ovan angivna utforingsexempel utan kan tillampas aven I manga andra utfOringsformer utan overskridande ax dess ram. It will be apparent from the foregoing that the invention encapsulates all of the inactivated impurities in association with previously used means for polishing metals. These disadvantages are remedied by using the agent according to the invention and by the specified method for grinding and polishing metals. It should further be clear that the origin has the stated advantages over the hitherto known methods. It should be noted that the invention is not limited to the above embodiments but can also be applied in many other embodiments without exceeding its scope.
