KT TOOL provides low-volume CNC milling and turning (mill-turn) services for complex, high-precision components. Our mill-turn process combines milling and turning operations in a single setup, enabling the machining of prismatic and rotational features without multiple re-clamping. This improves dimensional accuracy, reduces tolerance stack-up, and shortens lead time, making it ideal for parts with complex geometries and tight tolerances.
We support a wide range of materials including aluminum, stainless steel, titanium, and engineering plastics. From prototype to low-volume production, we ensure consistent quality, efficient machining, and reliable delivery for demanding applications.Application Scenarios
Technical Process
Adopt 5-axis CNC turn-mill integrated machining process: External flange holes and internal 3D spiral curved cavity are formed in one clamping linkage machining, which cannot be processed by 3-axis machine. No mold required, directly machined from digital models, naturally suitable for small-batch flexible mold parts customization.
Advantages of Small-batch Production
- Zero mold development cost, much lower custom cost than full mold opening for small-batch mold parts
- Direct 5-axis machining from digital models with fast delivery and flexible mold structure iteration
- Supports single-piece & small-batch mold insert production with strong customized flexibility
- 5-axis machining realizes closed spiral special-shaped cavities unavailable for 3-axis machines, optimal solution for small-batch precision molds
Core Characteristics
- Integrated 5-axis linkage molding of closed spiral inner cavity, unavailable for 3-axis machining
- Mirror polished inner cavity with ultra-high contour accuracy and coaxiality
- Mold steel material with high temperature resistance, wear resistance and corrosion resistance
- Mold-free production with fast delivery, perfectly suitable for small-batch mold development customization
- One-time clamping without secondary error, stable batch dimensional consistency
