CNC Lathe Parts In China
CNC lathe parts deliver exceptional precision and efficiency — ideal for prototypes, small batches, and large-scale production.
What Are CNC Lathe Parts
CNC lathe parts are precision-turned components created through advanced computer-controlled machining. By rotating raw materials such as aluminum, stainless steel, or brass against cutting tools, we achieve smooth surfaces, tight tolerances, and consistent performance.
At TiRapid, our CNC lathes deliver accuracy within ±0.01 mm — ensuring stability, durability, and efficiency for every project. Whether for aerospace shafts, automotive bushings, or medical connectors, our parts meet international quality standards.

1.Add a Radius to Internal Corners
Adding a small radius to internal corners helps improve turning efficiency and reduce tool stress. Sharp internal edges often cause cutter wear and poor surface finish. By introducing a radius equal to one-third of the cavity depth, tool life and machining stability are greatly enhanced.
2.Avoid Excessive Part Length or Depth
Keeping part dimensions within practical limits minimizes cutting time and setup complexity. Long or deep parts require additional support and special tooling, which increases costs. Keep the length-to-diameter ratio within 4:1 for better rigidity and efficiency.
3.Increase Wall Thickness for Stability
Thin walls may deform under cutting forces, especially in high-speed CNC lathe operations. Slightly increasing wall thickness enhances dimensional stability, reduces vibration, and shortens machining time.
4.Use Standard Diameters and Threads
Designing with standard bar diameters, hole sizes, and thread pitches simplifies production and lowers tooling costs. Standardized features reduce tool changes and setup time, ensuring faster, more cost-effective machining.
5.Specify Tight Tolerances Only When Necessary
Unnecessarily tight tolerances greatly increase machining time and inspection effort. Define precision levels based on functional needs — for most non-critical CNC lathe parts, standard tolerances are sufficient.
6.Leverage the Machinability of Metals
When designing CNC lathe parts, consider the machinability of materials such as brass, aluminum, or mild steel. These materials allow higher cutting speeds, smoother finishes, and longer tool life — all contributing to lower overall manufacturing cost.
