Horn 推出 DM40 模块化 PCD 立铣刀系列
Modular PCD end mill
Horn 以 DM40 系统扩展产品线，推出面向铝、压铸铝及 N、O 组材料通用铣削的模块化 PCD 立铣刀系列。该刀具系统由可长期重复使用的整体硬质合金刀柄和以钢为基体的 PCD 可换头组成，设计目标是减少磨损、节约资源并保证工艺经济性。模块化设计把长寿命部件与高磨损部件在功能上分开，端面切削刃是铣削中的主要磨损区，而切削长度超过直径两倍时崩刃风险上升，可换头系统在这些部位相比传统整体式刀具减少材料用量并降低后续成本。用户可在现场直接更换切削模块，装回后无需额外调整即可继续使用，从而减少机床停机时间、更换交期和维修成本。刀柄与可换头之间通过中央夹紧螺钉连接，形成力配合与形位配合，并配有颜色标识便于装配识别，内置防错原则避免装错。可换头与刀柄的接口保证新刀和重磨配对都能获得精确、无台阶的铣削结果。磨损的可换头在规定直径范围内最多可重磨两次。高轴向前角设计带来平稳切削和良好表面质量，几何形状兼顾通用应用的稳定铣削。该系列适用于批量生产和自动化产线。

With the DM40 system, Horn is expanding its product range to include a modular PCD end mill series for universal milling applications in aluminium, die-cast aluminium and materials in Groups N and O. The tool system combines a permanently reusable, solid carbide toolholder with a PCD-tipped, interchangeable head based on a steel body.
Horn has specifically designed the system to reduce wear, conserve resources and ensure cost-effective processes. The modular design functionally separates long-lasting components from those subject to high wear. The face cutting edges, in particular, are among the main wear zones in milling applications. At the same time, cutting lengths exceeding twice the diameter increase the risk of edge chipping. In these areas, the interchangeable head system reduces material usage and lowers follow-on costs compared with conventional monoblock tools.
Users can replace the cutting module directly on site. The tool can then be put back into service without any additional adjustment. This reduces machine downtime, replacement lead times and repair costs. The separation between the durable base toolholder and the replaceable head also ensures transparent and predictable maintenance costs. The system is therefore particularly suitable for series production and automated production lines.
Horn connects the PCD-tipped steel head to the toolholder via a central clamping screw, ensuring both a force-fit and a form-fit connection. Additional colour coding facilitates the identification of components during assembly. The integrated poka-yoke principle prevents assembly errors and enhances process reliability during use.
The interface between the interchangeable head and the toolholder ensures precise, step-free milling results for both new tools and resharpened tool pairings. Worn interchangeable heads can be resharpened up to twice within specified diameter ranges. The ability to resharpen reduces resource consumption and further improves the system’s cost-effectiveness.
The high axial rake angle design enables smooth cutting and excellent surface finishes. At the same time, the geometry ensures stable and reliable milling across universal applications.
FACTS
- Sustainable and straightforward replacement of the main wear zone
- Cost-effective standard range with universally applicable replacement heads
- Cost reduction thanks to a durable, solid carbide toolholder
