高速加工(HSM)通常与高速锭子(15K至40K RPM)和更高的料点相关联。它也被称为高速加工。它们是一个相同的,因为两者都代表了最准确和最短的循环时间中的加工组件。

In the past 10 to 15 years HSM was focused on the mold and die industry that uses pre-hardened materials and hardened tool steels—such as P-20, H-13, S-7 and D-2, which range in hardness from 28-62 HRC. The traditional method of finish machining hardened materials was EDM. In applications where HSM can replace the EDM process there will be considerable cost and cycle time reductions.

To be successful with HSM the following components need to be integrated; if one of these is incorrectly applied then your machining application will suffer.

不是每个人都了解如何以及何时应用正确的HSM原则。这并不是说每个加工应用程序都会受益于HSM,但是如果它不适用于错误信息和假设,许多应用程序都可以受益。

This is the most significant component for HSM, and should be designed specifically for HSM. The construction of the base, as well as the individual components—drive train, spindle and CNC—must be capable of handling the demands of HSM, especially in the case of hard milling.

It is much more than just looking at the maximum spindle rpm and feedrates. You must consider the size and mix of work to be machined. Know what you are planning to machine and evaluate accordingly. Are you going to be machining 2-D or 3-D surfaces on components or are materials to be machined, soft or hardened? These are just two examples.

用最高主轴RPM购买机器:40K带1,000 IPM进料。听起来很棒,对吗?让我们进一步进一步:所有部分都是非常复杂和小的,您拥有一些最好的HSM切割工具(在直径上1.0毫米。/ 2-长笛),专为60k转/分,芯片负载为0.003“。现在,您受到40k主轴的限制,因此您必须以40k的降低的RPM运行刀具。计算进料(40k x 2x.003“),您有240个IPM进料。现在我们拥有40k rpm和240个IPM,所以我们真的在移动!

等待,记住您将运行的零件的大小和复杂性?如果由于零件配置而无法达到240 IPM,该怎么办?您必须减慢主轴速度以维持.003的芯片载荷,因为实际切割时可以达到的实际进给率。重点是,您只能尽可能快地作为最慢的链接将允许(机器,数控控制,刀柄,切割工具)。

刀架
没有一个刀架类型,可以满足所有应用:收缩拟合,液压,夹头样式等。它们都具有可以根据应用程序应用的特定功能。对于HSK和CAT的特定功能,同样适用于主轴锥度接口,其本质上是不同的。这些需要根据您的加工要求进行评估。

平衡非常重要,但并非所有工具都需要平衡!这取决于刀架所需的内容。平衡考虑从大约8k rpm开始。这并不意味着您平衡所有将在8K运行的刀架,这意味着您开始思考平衡的地方。

For instance, if a tool is to be run at 9K rpm and used in a roughing application it very well may not need to be balanced. On the other hand, toolholders that will be used for finishing operations at speeds above 8K rpm may benefit from balancing. It all depends upon your requirements.

This is one area where companies try to cut corners because of the cost associated per piece, but there are more variables to consider—performance and better finishes, along with how long the tool will perform well in the cut. In some cases, you can throw commodity-type tools at an application, but you will have shorter and less consistent tool life, resulting in more downtime changing tools, etc. You need to know what is expected of the cutting tool—surface finish, material hardness and tool life requirements—so you can run lights out, unattended.

CAD/CAM Systems
There are still many CAD/CAM systems that do not have the capabilities to create toolpaths for HSM or hard milling routines easily. To be able to evaluate a system, you must understand what types of routines are required for HSM to attain the best results. Using experts in the field will reduce your learning curve considerably.
