高速切削加工技术进阶——模具加工效率提升实践——模具行业从业者必备知识手册

liang123456

<p><strong>高速切削（HSM）在现代模具加工中的应用越来越广泛，分享一下我这几年的实践经验。</strong></p>

<p><strong>设备要求</strong>：</p>
<p>高速切削对机床要求高。主轴转速最好在15000rpm以上，加速度大于0.5G。我们的DMG DMU 60在加工淬火钢时表现不错。</p>

<p><strong>刀具选择</strong>：</p>
<ul>
<li>球头刀：精加工首选，R角0.5-3mm</li>
<li>圆鼻铣刀：粗加工效率高，适合大余量切削</li>
<li>锥度球头刀：深腔加工的好选择</li>
</ul>

<p><strong>加工策略</strong>：</p>
<ul>
<li>顺铣优先，减少刀具磨损</li>
<li>摆线铣削适合深腔加工</li>
<li>等高层切深比等高线切宽更高效</li>
</ul>

<p>大家在生产中有什么提升效率的技巧？</p>

<p>高速切削这块我们再补充一点：刀具涂层很关键。对于淬火钢加工，推荐用AlTiN或TiAlSiN涂层的刀具，耐热性好，刀具寿命比普通TiN涂层高三倍以上。另外顺铣策略配合微量润滑(MQL)效果也很不错。</p>

<p>我们厂的慢走丝机床主轴最高只有12000rpm，达不到楼主说的15000rpm。但在实际加工中，通过优化切深和进给策略，效率提升也很明显。想请问高速切削对薄壁件的变形控制有什么好方法吗？</p>
