Micro Precision Brass CNC Turning Parts with 0.5μm Real Gold Plating

High-Volume Production of Miniature Brass Electronic Components with ±0.01mm Accuracy

YS Precision specializes in manufacturing micro precision brass CNC turning parts for electronic components and high-performance industrial applications.

For this project, we produced miniature brass crimping rings using precision CNC turning technology. These extremely small components required strict dimensional control, excellent surface quality, and premium gold plating treatment.

The finished parts featured an outer diameter of only 2.5mm, an inner diameter of 1.9mm, and a height of approximately 1.5mm.

With production quantities reaching approximately 50,000 pieces per batch, YS Precision maintained stable quality with ±0.01mm dimensional accuracy and a 0.5μm real gold plating finish.

These precision brass components were exported to customers in the Americas for use in electronic equipment applications.

Project Overview

Precision Brass CNC Turning for Miniature Components

Brass is one of the preferred materials for miniature precision components because of its excellent machining performance and reliable physical properties.

Compared with other metals, brass offers:

• Excellent machinability
• Stable dimensional performance
• Smooth surface finish
• Good electrical conductivity
• Excellent compatibility with plating processes

For this project, the micro brass components required extremely small machining features. YS Precision optimized the CNC turning process to achieve consistent dimensions and surface quality throughout large-volume production.

Our engineers carefully controlled:

• Cutting parameters
• Tool wear
• Burr formation
• Dimensional variation
• Production consistency

Micro CNC Turning Capability for Ultra-Small Brass Parts

Producing components with a diameter of only a few millimeters requires specialized machining experience.

YS Precision has extensive experience manufacturing:

• Brass micro shafts
• Precision pins
• Contact rings
• Bushings
• Sleeves
• Electronic connectors
• Miniature turned components

Our precision CNC turning processes are capable of handling challenging requirements including:

• Small diameter machining
• Tight tolerance control
• High-volume production
• Complex surface finishing requirements

±0.01mm Precision Control for Electronic Components

For electronic applications, small components often directly affect product assembly and performance.

Even minor dimensional changes can impact:

• Mechanical fitting
• Electrical contact stability
• Product reliability

For this brass crimping ring project, YS Precision controlled critical dimensions within:

±0.01mm tolerance

Our quality control process includes:

First Article Inspection

Verification of machining parameters and critical dimensions before production.

In-Process Inspection

Continuous monitoring during mass production to ensure consistency.

Final Inspection

Complete dimensional and appearance inspection before shipment.

0.5μm Real Gold Plating for Brass Electronic Components

The customer's application required a genuine gold plating finish with a thickness of:

0.5μm Gold Plating

Gold plating provides important advantages for electronic components:

• Excellent electrical conductivity
• Corrosion resistance
• Stable contact performance
• Long service life
• Premium surface appearance

For plated brass components, surface preparation before plating is critical.

YS Precision carefully controls:

• Machining surface quality
• Cleaning process
• Plating thickness
• Surface appearance

to ensure reliable and consistent gold-plated parts.

High Volume Brass CNC Turning Production

Although these parts are extremely small, the production volume was significant.

Each production batch required approximately:

50,000 precision brass components

Large-volume production of miniature parts requires:

• Stable machining processes
• Efficient production management
• Strict quality monitoring
• Reliable packaging methods

YS Precision supports customers from prototype validation to continuous production supply.
