In the competitive world of precision manufacturing, the quality of threaded holes can be the difference between a flawless assembly and a costly failure. For businesses relying on machined components, mastering CNC drilling, tapping, and threading techniques is not just a technical detail—it's a critical business advantage. As a leading onestopshop for custom CNC parts, we leverage advanced methodologies to ensure every thread is perfect, delivering reliability and value to your global supply chain.
The process begins with precision CNC Drilling. Creating the pilot hole for a thread is a foundational step. We utilize highperformance drills and optimized pecking cycles (G83) to efficiently evacuate chips, preventing work hardening and ensuring a clean, accurately sized hole. This is crucial as the quality of the drilled hole directly impacts the success of the subsequent tapping operation.
Following drilling, CNC Tapping is employed to cut the internal threads. We strategically choose between different tap geometries (spiral point, spiral flute) based on the material—whether it's aluminum, stainless steel, or hightemp alloys. For highvolume production, we often use rigid tapping, where the spindle's rotation and Zaxis movement are perfectly synchronized by the CNC control. This eliminates the need for a tensioncompression holder, resulting in faster cycle times and exceptionally consistent thread quality.
For the most demanding applications, especially in tough materials, Thread Milling offers superior flexibility and strength. Unlike tapping, a thread mill produces threads through a circular interpolation path. A single tool can create multiple thread sizes and pitches, reducing tooling inventory. More importantly, thread milling generates less cutting force, is less prone to tool breakage, and produces stronger threads due to the coldworking effect on the material.
Our expertise extends beyond the machine. We provide comprehensive Design for Manufacturability (DFM) feedback, advising on optimal thread depths, hole positions, and material selections to enhance part strength and reduce production costs.
