Professional CNC Turning Services

Precision Stainless Steel & Custom Metal Components

We are a CNC turning manufacturer based in China, specializing in precision machining. With over 50 advanced CNC lathes and supporting automation equipment, we provide one-stop manufacturing solutions for carbon steel, stainless steel (SUS303, SUS304), aluminum alloys, and engineering plastics.

With nearly 20 years of experience, we deliver consistent quality and reliable performance across a wide range of stainless steel turned components and custom metal parts.

Core Capabilities

Precision CNC Turning

We focus on the efficient production of complex parts, with particular expertise in SUS303 stainless steel shaft components. Strict process control ensures consistent dimensions and high-quality surface finishes across all batches of stainless steel turned components.

Thread Machining

Dedicated tapping equipment allows precise machining of both internal and external threads, ensuring proper fit and compliance with tolerance requirements.

Centerless Grinding

For applications requiring tighter diameter tolerances and improved surface finish, we offer centerless grinding as a secondary process. This ensures excellent roundness and smoothness for shaft components.

Quality Control System

Quality is at the core of our operations. Our factory operates in accordance with ISO 9001 standards.

Material Inspection

All incoming materials - including C36000 free-cutting brass, carbon steel, and stainless steel - are verified for chemical composition before production.

In-Process Control

We implement first article inspection and routine in-process checks. Production is monitored using:

• Optical measurement systems

• High-precision micrometers

• Vernier calipers

This ensures stable and controlled production quality.

Final Inspection

All products undergo 100% inspection prior to shipment:

• Surface roughness is verified using a roughness tester

• Thread quality is checked using GO/NO-GO gauges

This ensures every component meets required specifications.

Packaging & Logistics

To ensure safe delivery of precision components, we use: Thermoformed trays + high-strength cartons

This packaging method secures each part, minimizes movement during transport, and protects against impact and surface damage-ensuring all stainless steel turned components arrive in optimal condition.
