Removes material from the workpiece end to create flat reference surfaces — part of our one-setup turn-mill workflow for consistent precision.
Creates or enlarges holes in a single setup, eliminating secondary operations and reducing tolerance stack-up.
Cuts internal/external metric, imperial, and pipe threads for fasteners, fittings, and assemblies.
Separates finished parts from stock material with a clean edge.
KT Advantages
One Setup, Multiple Operations
Our advanced turn-mill equipment performs milling, drilling, tapping, and multi-process machining in a single setup, greatly reducing errors from repeated clamping. Our turn-mill centers integrate turning and milling in one machine, ideal for shafts with eccentric holes, keyways, flats, and complex end features.
Reducing setups improves efficiency and dramatically enhances concentricity, stability, and positional tolerance consistency — critical for high-volume OEM assembly.

Tolerance Guide
Precision is crucial in CNC turning to ensure parts meet exact specifications and fit accurately within assemblies. Tolerances are determined by considering factors such as part function, material properties, and machining capabilities. By defining precise tolerances, we balance performance requirements with manufacturing feasibility, optimizing both quality and cost efficiency for each project.
Proper tolerance design in CNC turning helps minimize machining costs and enhance production efficiency. To achieve this, consider the following best practices:
- Avoid over-tight tolerances where not functionally required
- Use standard tolerances for non-critical features
- Simplify complex geometries when possible
- Maintain uniform wall thickness for better stability
- Consider material behavior during machining
| Tolerance Type | Standard Tolerance (±mm) | Material | Cost Impact | Machining Feasibility |
| Non-critical Linear Dimensions | ± 0.10 | Aluminum (6061, 7075), Brass | Low | Easy to machine with standard tools |
| Critical Linear Dimensions | ± 0.05 | Stainless Steel (304, 316) | Medium | Requires more machining time, tougher material |
| High-precision Linear | ± 0.02 / 0.03 | Titanium (Ti) | High | Needs 5-axis machining and CMM inspection |
| Non-critical Linear Dimensions | ± 0.10 | PEEK, POM, PC, PTFE | Medium | Good for high-performance parts, but may require specialized tooling |
