Fix Poor Hole Position Accuracy & Thread Machining Defects in Milling Parts
Precision hole position and thread structure are key assembly structures of CNC milling parts, and also high-failure-rate processing links. Common problems include offset hole positions, uneven hole wall roughness, unqualified thread pitch, broken teeth and missing threads. These subtle processing defects will directly lead to failed part assembly, loose screw fixation and poor structural sealing performance. Especially for automotive parts, medical equipment components and electronic precision parts, unqualified hole and thread structures will bring hidden dangers of equipment loosening and functional failure in later use.
Our precision CNC milling process realizes one-time integrated forming of hole position drilling, reaming and thread tapping. We adopt high-precision positioning fixtures and professional drilling and tapping tools to ensure accurate hole position spacing and verticality. Strictly control the cutting speed and tapping torque to avoid thread tooth breakage, sliding teeth and uneven hole walls. All hole positions and threads are inspected by professional testing equipment to meet international standard tolerance requirements. The processed parts have precise hole positions, smooth hole walls and standard threads, which ensure tight assembly, stable fixation and good sealing performance, completely solving assembly failure and structural looseness caused by hole and thread defects.
