Antes de moer uma broca helicoidal de haste reta<\/h4>\n<p>Primeiro, coloque a aresta de corte principal das brocas helicoidais e a superf\u00edcie do rebolo em uma superf\u00edcie horizontal, garantindo assim que toda a aresta de corte seja retificada quando a aresta de corte entrar em contato com a superf\u00edcie do rebolo<\/p>\n<p>Este \u00e9 o passo di da posi\u00e7\u00e3o relativa da broca e do rebolo. Depois que a posi\u00e7\u00e3o for definida, mova lentamente para a superf\u00edcie do rebolo<\/p>\n<h4>2. Refere-se \u00e0 rela\u00e7\u00e3o posicional entre o eixo das brocas helicoidais e a superf\u00edcie do rebolo<\/h4>\n<p>\u00c9 suficiente levar 60 \u00b0, esse \u00e2ngulo geralmente \u00e9 mais preciso<\/p>\n<p>Aqui devemos prestar aten\u00e7\u00e3o \u00e0 posi\u00e7\u00e3o horizontal relativa e \u00e0 posi\u00e7\u00e3o angular da broca antes de afiar. Ambos devem ser levados em considera\u00e7\u00e3o<\/p>\n<p>N\u00e3o negligencie o \u00e2ngulo para achatar a borda, ou ignore a borda plana por causa do \u00e2ngulo<\/p>\n<h4>3. Retifique a partir da borda<\/h4>\n<p>Depois que a aresta de corte entrar em contato com o rebolo, ela deve ser retificada a partir da aresta de corte principal<\/p>\n<p>The cutting edge of<a href=\"https:\/\/www.tenyutool.com\/pt\/fabricantes-de-brocas-helicoidais\/\" title=\" the twist drill bits \"> the twist drill bits <\/a>first contacts the grinding wheel, and then the entire flank surface is slowly ground down<\/p>\n<h4>4. Ao cortar a broca, voc\u00ea pode tocar levemente no rebolo<\/h4>\n<p>Primeiro execute uma certa quantidade de afia\u00e7\u00e3o e preste aten\u00e7\u00e3o para observar a uniformidade da fa\u00edsca, ajuste a press\u00e3o da m\u00e3o no tempo e preste aten\u00e7\u00e3o ao resfriamento da broca<\/p>\n<p>Recozimento at\u00e9 a ponta. Quando a temperatura da aresta de corte estiver alta, a broca deve ser resfriada a tempo<\/p>\n<h4>5. Esta \u00e9 uma opera\u00e7\u00e3o de retifica\u00e7\u00e3o de broca padr\u00e3o<\/h4>\n<p>A aresta de corte principal deve balan\u00e7ar para cima e para baixo no rebolo, ou seja, a m\u00e3o que segura a frente da broca deve balan\u00e7ar a broca para cima e para baixo na superf\u00edcie do rebolo uniformemente<\/p>\n<p>Mas a m\u00e3o que segura a al\u00e7a n\u00e3o pode balan\u00e7ar, e a al\u00e7a traseira deve ser impedida de se inclinar para cima, ou seja, a cauda da broca n\u00e3o pode ser levantada acima da linha central horizontal do rebolo, caso contr\u00e1rio, a aresta de corte ficar\u00e1 cega e n\u00e3o poder\u00e1 ser cortar<\/p>\n<h4>6. Este \u00e9 um passo chave<\/h4>\n<p>A broca est\u00e1 bem ou mal aterrada, e a t\u00e9cnica \u00e9 muito importante<\/p>\n<p>Quando a moagem for quase a mesma, comece pela aresta de corte e, em seguida, pressione-a suavemente no canto traseiro para tornar a parte de tr\u00e1s da aresta de corte mais suave<\/p>\n<h4>7. Certifique-se de que a aresta de corte das brocas helicoidais esteja alinhada com o raio e, lentamente, remova os dois lados simetricamente<\/h4>\n<p>Depois que a aresta de corte \u00e9 retificada, a outra aresta de corte deve ser retificada e a aresta de corte deve estar no meio dos lados vertical e horizontal da broca<\/p>\n<p>As arestas de corte em ambos os lados devem ser sim\u00e9tricas. \u00c9 adequado para retifica\u00e7\u00e3o de \u00e2ngulo de inclina\u00e7\u00e3o, o centro da ponta \u00e9 sim\u00e9trico e as duas bordas s\u00e3o sim\u00e9tricas<\/p>\n<p>Ao perfurar, o chip de perfura\u00e7\u00e3o \u00e9 leve, sem vibra\u00e7\u00e3o e n\u00e3o se expande<\/p>\n<h4>8. Depois que as duas bordas da broca s\u00e3o retificadas<\/h4>\n<p>Existe um plano na ponta das duas arestas, que afeta o posicionamento central da broca<\/p>\n<p>Voc\u00ea precisa chanfrar atr\u00e1s da borda e tentar afiar o plano da borda<\/p>\n<h4>9. O m\u00e9todo \u00e9 erguer as brocas helicoidais, alinh\u00e1-las com o canto do rebolo e despejar um pequeno sulco na raiz atr\u00e1s da l\u00e2mina contra a ponta da l\u00e2mina<\/h4>\n<p>Este tamb\u00e9m \u00e9 um ponto importante para a centraliza\u00e7\u00e3o da broca e corte leve. Observe que ao chanfrar a aresta de corte, n\u00e3o a retifique at\u00e9 a aresta de corte principal<\/p>\n<p>Isso aumentar\u00e1 o \u00e2ngulo de inclina\u00e7\u00e3o da aresta de corte principal, o que afetar\u00e1 diretamente a fura\u00e7\u00e3o<\/p>\n<p>Mastering the manual sharpening method of <a href=\"https:\/\/www.tenyutool.com\/pt\/fabricantes-de-brocas-helicoidais\/\" title=\"a straight-hand twist drill bits\">a straight-hand twist drill bits<\/a> is an important job<\/p>\n<p>Acumula experi\u00eancia na opera\u00e7\u00e3o real<\/p>\n<p>Know more about <a href=\"https:\/\/www.tenyutool.com\/pt\/fabricantes-de-brocas-helicoidais\/\" title=\"the drill bits\">the drill bits<\/a> e <a href=\"https:\/\/www.tenyutool.com\/pt\/laminas-de-serra\/\" title=\"l\u00e2minas de serra\">l\u00e2minas de serra<\/a>,\u00a0<a href=\"https:\/\/www.tenyutool.com\/pt\/fabricantes-de-brocas-helicoidais\/\" title=\"click here\">click here<\/a>!<\/p>\n<h2>Request Your Free Sample<\/h2>\n<div style=\"display: flex;
