鉆不銹鋼用什么鉆頭?

首先在選擇鉆頭之前,請(qǐng)隨小編看一看不銹鋼工件加工時(shí)難點(diǎn)是什么?找出難點(diǎn)就可以很準(zhǔn)確、很快速的找到使用的鉆頭了。

一、不銹鋼工件加工的難點(diǎn)有哪些?

1.容易粘刀: 不銹鋼加工時(shí)切屑強(qiáng)韌、切削溫度很高。當(dāng)強(qiáng)韌的切屑流經(jīng)前刀面時(shí),將產(chǎn)生粘結(jié)、熔焊等粘刀現(xiàn)象,影響加工零件表面粗糙度;

2.加工硬化嚴(yán)重:奧氏體不銹鋼以及一些高溫合金不銹鋼均為奧氏體組織,切削時(shí)加工硬化傾向大,通常是普通碳素鋼的數(shù)倍,刀具在加工硬化區(qū)域內(nèi)切削,使刀具壽命縮短;

3.切削力大,切削溫度高:該類型材料強(qiáng)度大,切削時(shí)切向應(yīng)力大、塑性變形大,因而切削力大。此外材料導(dǎo)熱性極差,造成切削溫度升高,且高溫往往集中在刀具刃口附近的狹長(zhǎng)區(qū)域內(nèi),從而加快了刀具的磨損;

4.刀具磨損快:上述材料一般含高熔點(diǎn)元素、塑性大,切削溫度高,使刀具磨損加快,磨刀、換刀頻繁,從而影響了生產(chǎn)效率,提高了刀具使用成本;

二、通過上述加工難點(diǎn)分析,不銹鋼的在鉆削加工中的對(duì)不銹鋼鉆頭的選擇和加工參數(shù)與普的材料都有許多不同,對(duì)鉆頭的選擇建議如下

硬質(zhì)合金不銹鋼鉆頭

㈠涂層:

高溫合金與難加工不銹鋼優(yōu)選;

韌性好的細(xì)顆粒材質(zhì)等級(jí)和 TiAIN 鍍層;

紅硬性極好

抗化學(xué)與氧化磨損**

PVD 鍍層;

(Ti,AI) N TiN.

㈡鉆頭本體:在鉆尖,橫刃,刃口處理;

㈢切削液推薦乳化液,濃度含量為 10%;

含鈷高速鋼

含鈷高速鋼

涂層:耐高溫,抗粘,耐磨

鉆頭本體:含鈷高速鋼本體韌性更好。
