Introduction to Thread whirling
Thread whirling is an advanced, efficient processing technology that can significantly improve productivity and part quality. But how does it work and what are the main benefits? In this initial Scholar’s guide, we will cover the basics of thread whirling.
How thread whirling Works
In thread whirling, the cutter revolves eccentrically while rotating around the central axis of the workpiece. This produces a cycloidal tool movement that ensures continuous and even cutting.
不存在传统铣削中常见的断续切削或径向力。一致的切屑厚度和均匀磨损可显着延长刀具寿命。振动和颤动也大大减少。
相对于传统铣削的优势
- 更快的金属去除率:旋风铣可实现非常高的进给率,比传统铣削高出 10 倍。这会带来巨大的生产力提升。
- 改进的表面光洁度:平滑的摆线运动消除了振动和颤痕,留下了出色的表面光洁度。
- 更长的刀具寿命:由于没有径向力和恒定的切屑负载,刀具的使用寿命显着延长。
- 减少振动和颤振:平稳的运动可防止振动,实现无颤振的过程。
Applications of thread Whirling
- Medical Implants:
- Producing bone screws and dental implants, which require high precision and surface finish.
- Aerospace Fasteners:
- Crafting threads on aerospace bolts and screws that must withstand high stress and corrosion.
- Precision Lead Screws:
- Creating high-precision lead screws used in machine tools, measuring devices, and linear actuators.
- Automotive Components:
- Manufacturing ball screw drives and various threaded automotive parts like drive shafts and steering components.
- Hydraulic Systems:
- Machining threads on hydraulic pistons and valves that require precise control and movement.
- Oil and Gas Industry:
- Cutting threads on drill strings, tubulars, and other components used in the extraction and processing of oil and gas.
- Electronic Assemblies:
- Producing miniature and precision threads for electronic components such as connectors and assemblies.
- Injection Molding Machines:
- Making high-quality screws for plasticating systems in injection molding equipment.
- Earth Moving Equipment:
- Crafting resilient and durable threads for heavy machinery and earth moving equipment.
- Marine Hardware:
- Manufacturing screws and threaded parts that are resistant to saltwater corrosion.
The thread whirling process is particularly advantageous because it allows for the creation of intricate thread profiles, deep thread paths, and long out-of-round threads with high efficiency and accuracy. It is often used for difficult-to-machine materials and complex parts where traditional thread cutting would be less efficient or effective.
成功实施的秘诀
优化速度、切屑负载、刀具路径策略和机床刚性是充分发挥旋风铣削潜力的关键。请咨询您的工具提供商,获取有关最大限度提高性能的建议。
使用什么类型的刀具?
需要带有偏心叶片或旋风环的特殊旋风铣刀。它们安装在标准镗杆或主轴上。
如何处理刚性和振动?
机器、夹具和刀具必须具有非常高的刚性。平衡的刀具和直径超过 25 毫米的刀柄有助于抑制振动。
预期的表面光洁度如何?
可以实现低至 Ra 0.2 微米的极其精细的表面处理。平滑的切割运动消除了颤痕。
Can Thread whirling be used on CNC machines?
是的,数控机床可以通过正确的编程和刀具设置来执行旋风铣削操作。 4 轴或 5 轴机器提供最大的灵活性。
旋风铣仅适用于难加工材料吗?
不,所有铝合金、钢、钛和其他金属都实现了生产力的大幅提高。这是一种通用加工解决方案。
结论
With its continuous cutting action and eccentric tool movement, 螺纹旋风铣 can unlock dramatic improvements in milling efficiency. Understanding how to implement this technology properly will allow you to increase metal removal rates and boost your shop’s production capabilities.
