CNC Milling
High-tolerance milling solutions for complex geometries, engineered for aerospace, oil & gas, and semiconductor performance.
Who We Are
What is CNC Milling?
CNC Milling is a subtractive machining process using multi-axis cutting tools to shape metal or plastic workpieces with pinpoint precision. At Hytech, our milling centers are optimized for both prototyping and production — delivering dimensional accuracy and repeatability with every run.
Our Capabilities
Swarf Milling
For complex angled surfaces and contoured profiles.
Pocketing & Slotting
For enclosures, internal geometries, and structural parts.
Undercut Machining
Ideal for aerospace components with hidden reliefs.
5-Face Machining
Single-setup machining across five surfaces for high accuracy.
Indexing Drilling
Precise multi-angle drilling using rotary tables.
Benefit of CNC Milling
Tight tolerance: ±0.01mm achievable
Complex geometry expertise
Consistent batch production
Quick turnaround on prototypes
High Precision Tolerances

CNC Milling Tolerances & Standards
| Description | General Tolerance or Standard |
|---|---|
| Maximum Part Size | Milled parts up to 80” x 48” x 24” (2,032 x 1,219 x 610 mm). |
| Distance Dimensions | For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”. |
| Precision Tolerances | Manufacture and inspect to tight tolerances, including sub +/- 0.001” tolerances, per your drawing specifications and GD&T callouts. |
| Minimum Feature Size | 0.020” (0.50 mm). This may vary depending on part geometry and chosen material. |
| Surface Finish | The standard finish is as-machined: 125 Ra or better. Additional finishing options can be specified when getting a quote. |
