硬质合金钻头是由碳化钨材料制成的钻孔工具。它们提供了穿透率和精度的最佳组合。它可用于在各种金属材料(如钢、铝和青铜)以及其他非金属材料(如木材、混凝土、砖石、瓷砖等)上钻孔。

我们为不同的应用制造和储存硬质合金钻头。我们的标准钻头是用于一般用途的 3D 和 5D 硬质合金钻头,带有青铜涂层。钻头的基底材料、几何形状和涂层可以决定它们在某些材料中的钻孔性能。我们可以根据您的要求制造。

什么是CNC钻孔?

钻孔是孔加工的基本方法。钻孔通常在钻床和车床上进行,也可以在镗床或铣床上进行。常用的钻床包括台式钻床,立式钻床和径向钻床。

钻削运动构成:钻头的旋转运动是主要切削运动,加工精度低。

用钻头在固体材料上钻孔的过程称为钻孔。钻孔是孔加工的基本方法之一。钻孔通常在钻孔机或车床上或在镗床或铣床上进行。

钻孔机是进行孔加工的主要工具。钻孔主要是在使用钻头的钻床上进行的。在车床上钻孔时,工件旋转,刀具进行进给运动。在钻孔机上加工时,工件不移动,刀具执行主旋转运动,并沿轴向移动以执行进给运动。

因此,钻床适用于在不具有对称旋转轴的工件上加工孔,尤其是在多孔加工中,例如在机壳和机架等零件上加工孔。除钻孔机外,还可以完成孔的扩孔,扩孔,平面钻孔,攻丝等工作。

Diffrence between drilling and milling

Drilling and milling are two different processes for machining a workpiece. A drill uses up-and-down motions to cut the material while milling uses sideways motions. The main difference between milling and drilling is the speed. Drilling requires a low spindle speed, while milling requires a high spindle speed. You can see the full page in our blog 这里.

硬质合金钻头还是冷却液钻头?

The internal coolant carbide drill is always preferred to avoid chip jamming when drilling deeper holes (4-5 × DC), especially in long chipping materials.

Meetyou has designed a cooling method by applying coolant through the internal hole of the drill bit. This method cools the drill bit more efficiently. The coolant flows right out of the cutting tip of the drill. This cools the hottest part of the drill bit and removes chips by flushing them out of the hole.

Our internal coolant drill bits are the best choice for high-speed operations. The concentrated cooling and rapid chip removal increase the life of the drill and improve production quality.

与高速钢钻头相比

Carbide drill bits are for industrial use for a variety of materials such as aluminum, steel, nonferrous heavy metal, and stainless steel.  Carbide drills maintain a sharp cutting edge with better wear resistance than high speed steel drills or cobalt drills and are run at higher speed rates as they absorb heat more efficiently.

As shown in the chart, carbide drills have better hardness, higher temperature endurance along with longer cutting time.

We supply both solid and coolant through drills in a wide range of sizes.  Our coolant drills are standard with AlTiN coating to perform a higher cost per drilled hole.
