CNC Turning Surface Finishes
Finishing options improve appearance, corrosion resistance, and durability:
As Machined + Deburring
The standard finish straight from the CNC machine. All sharp edges and burrs are removed for a clean, functional part. Typical surface roughness: Ra 3.2 μm. Cost-effective with no additional processing time.
Sandblasting
A process that propels abrasive media at the part surface to create a uniform matte or satin texture, hiding tool marks and providing a great base for painting. Available in various grit sizes for different texture levels.
Anodizing
An electrochemical process for aluminum that increases corrosion resistance and surface hardness. It also allows for dyeing the part in various colors (Type II and Type III Hardcoat). Provides excellent wear resistance and electrical insulation.
Electroplating
A process that deposits a thin layer of metal (e.g., nickel, chrome, zinc, gold) onto the part surface for enhanced corrosion resistance, wear resistance, and aesthetic appeal. Can improve electrical conductivity and solderability.
Electrochemical Polishing
An advanced process that uses electrical current and specialized electrolytes to remove surface material, resulting in a smooth, mirror-like finish. Ideal for complex geometries and internal surfaces that are difficult to polish mechanically.
Brushed Finish
A directional satin finish created by brushing the material with an abrasive belt. Common for decorative metal parts like appliance housings, architectural elements, and consumer products. Available in different patterns and coarseness.
Powder Coating
A dry finishing process where electrostatically charged pigment powder is applied to a part and then cured under heat to form a durable, protective, and decorative layer. Available in countless colors and textures with excellent durability.
Laser Engraving
A precise, permanent marking method to add serial numbers, logos, barcodes, or other identification directly onto the part surface. Works on metals, plastics, and other materials without affecting material properties.
CNC Turning Tolerance Standards
Introduction to Tolerances in CNC Turning
CNC turning tolerances define the allowable deviation in part dimensions during machining. At HRC, we maintain high precision standards to ensure part accuracy, compatibility, and performance.
Standard Tolerance Capabilities
Our turning capabilities cover a wide range of tolerance levels. Below are our general and precision standards for common features:
| Feature Type | Standard | Precision |
|---|---|---|
| Diameters | ±0.025 mm (±0.001") | ±0.0127 mm (±0.0005") |
| Linear dimensions | ±0.05 mm (±0.002") | ±0.025 mm (±0.001") |
| Concentricity | 0.05 mm (0.002") | 0.025 mm (0.001") |
| True position | 0.08 mm (0.003") | 0.05 mm (0.002") |
Factors Affecting Tolerances
Several elements determine achievable tolerances:
- Material properties: Hardness, stability, and thermal expansion.
- Part geometry: Thin walls or long parts are harder to maintain precise.
- Feature location: Features far from the chuck can increase deviation.
- Machine capability: Rigidity, spindle precision, and tool wear.
- Environment: Temperature and humidity affect dimensional stability.
Inspection Methods
We use advanced tools to guarantee accuracy:
CMM
Coordinate Measuring Machines capture precise 3D measurements for complex geometries.
Optical Comparators
Profile inspection and dimensional verification for intricate features.
Surface Roughness Testers
Ensures surface finish meets specified requirements.
Note: All tolerances comply with ISO 2768 and ASME Y14.5 standards, as well as customer-specific requirements.
Custom Turning Design Guidelines

Efficient CNC turned parts follow these key principles:
- Simplify geometries where possible
- Standardize features and sizes
- Ensure tool access and clearance
- Design for stability during machining
- Minimize setups and operations
