Swiss CNC Turning Services for Aerospace Precision Components

Reliable Manufacturing Partner for High-Precision Brass Contact Pins, Standoffs and Miniature Turned Parts

Supporting Aerospace and High-Tech Industries with Stable Production of Critical Small Components

Project Background

A global aerospace equipment manufacturer required a reliable manufacturing partner for a series of precision brass components used in aerospace systems.
The project involved multiple miniature turned parts, including:

• Brass contact pins
• Precision standoffs
• Small support components
• Custom precision connectors

Although these components are small in size, they are critical functional parts within the final assembly.
The customer required a supplier capable of providing:

• Consistent dimensional accuracy
• Stable production quality
• Long-term manufacturing reliability
• Professional export support

Based on customer-provided:

• 2D engineering drawings
• 3D CAD models

YS Precision developed a complete Swiss CNC turning manufacturing solution for approximately:
10,000 sets of aerospace precision components.
 

Project Overview

Customer Challenge

Finding a Reliable Supplier for Precision Miniature Components

For aerospace applications, component size does not determine importance.
Small precision components often directly affect:

• Assembly accuracy
• Electrical connection reliability
• System performance

The customer needed more than a machining supplier.
They needed a manufacturing partner who could ensure:

• Stable quality across production batches
• Consistent dimensions over thousands of parts
• Reliable delivery schedules
• Reduced supply chain complexity

Key Manufacturing Challenges

1. Complex Miniature Component Manufacturing

The parts included multiple precision features:

• Small diameter sections
• Internal bores
• External threads
• Precision grooves
• Multiple diameter transitions

These structures require:

• Stable machining conditions
• Experienced process planning
• Accurate tooling management

2. Tight Tolerance Control

Some critical features required:
±0.005mm tolerance
while other dimensions required:
±0.01mm tolerance
For aerospace-related components, maintaining these tolerances consistently during production is more challenging than producing individual prototype samples.
The production challenge was: Maintaining the same quality from the first part to the 10,000th part.
 

3. Brass Material Machining Stability

Brass is widely used for precision aerospace and electronic components because of:

• Excellent machinability
• Good dimensional stability
• Electrical conductivity

However, precision brass machining still requires control of:

• Surface finish
• Burr formation
• Tool wear
• Dimensional variation
