American high-end equipment supplier CNC parts cooperation case

Customer and project background

Customer introduction

Our customer is a high-end equipment supplier with a high reputation in the field of industrial equipment manufacturing in the United States. It focuses on providing key solutions for precision machinery, automated production lines, agricultural irrigation and marine engineering. Its products have extremely high requirements for the quality, precision and reliability of accessories, especially focusing on performance in harsh environments such as high pressure and corrosion.

Project launch

This cooperation revolves around 4 CNC accessories for water pipe connectors:

1. Quick-release leather hose connector (for rapid deployment of emergency water systems)
2. Double-head threaded connector (for multi-pipe integration)
3. Stainless steel knurled connector (manual adjustment in a small space, can be assembled with double-head threaded connectors)
4. Knurled internal thread connector (reliable connection between hose and valve)

The customer urgently needs this batch of high-precision accessories due to business expansion to ensure that the equipment is delivered on time, and at the same time requires compliance with ISO 9001:2015 quality standards and strict environmental tolerance.

Project Challenges and Innovative Responses

Core Challenges

1. Drawings were revised many times: the initial design had problems such as thread parameter deviation and insufficient structural strength, requiring 5 key revisions
2. Strict precision requirements: the tolerance of some parts is required to be ±0.005mm, far exceeding the conventional CNC processing standards
3. Urgent delivery pressure: customers require the sample cycle to be compressed to 7 days and the mass production cycle to be 4 weeks

Solutions

• The engineering team quickly analyzed and reviewed the drawings in detail and proposed accurate modification plans; maintained close communication with customers and provided timely feedback on the progress of modifications

• Photographing detail pictures of parts and operation demonstration videos at key points. Through this intuitive way, customers can clearly see the details and actual effects of the product

• Material control: 316L stainless steel containing 2.5% molybdenum is preferred, and ultrasonic flaw detection and chemical composition detection are carried out before storage
• Processing process:
  • 5-axis CNC machine tool performs multi-process integrated processing, and the thread is cut by a single-point diamond tool
  • The knurling process uses a customized mold to ensure that the texture uniformity error is less than 0.02mm
  • The surface is polished by 800-2000 mesh sandpaper progressively, and finally achieves a mirror effect (Ra≤0.4μm)

Full process quality control

• Detection system: 100% dimensional detection (CMM three-coordinate measuring machine), 100% pressure test (no leakage after 30 minutes of pressure maintenance)
• Traceability system: Each part is laser-etched with a unique number, which is associated with processing parameters, detection data and delivery records

Cooperation results and continued trust

A good start for the first cooperation

• During the first cooperation, the customer only purchased 500 studs. After receiving the goods, he highly praised the quality and surface polishing effect of the products, and was also satisfied with our delivery speed. This laid a solid foundation for the subsequent in-depth cooperation.

In-depth cooperation and bulk orders

• Based on the good experience of the first cooperation, the customer then consulted 4 CNC accessories and asked for 50 samples of each. We completed the sample task with high quality according to the customer's requirements. The customer was very satisfied after receiving the samples and soon placed bulk orders for 2,500 and 5,000 respectively. In the subsequent 4 transactions, our products and services have won unanimous praise from customers.

Continuous return orders and establish long-term cooperative relations

• With high-quality product quality, efficient delivery speed and professional service, the customer has established a long-term and stable cooperative relationship with us, and is still continuing to return orders. We will continue to uphold the attitude of excellence, provide customers with better quality CNC accessories and more complete services, and jointly promote the continuous development of both parties' business.

Case summary: The dual value of precision manufacturing and agile services
This cooperation successfully transformed drawing defects into industry benchmark products through technical breakthroughs (high-precision processing, material optimization) and service innovation (quick response, transparent communication). We have proved that in the field of high-end CNC accessories, it is necessary not only to break through the process limits, but also to establish full-chain collaborative capabilities from design to delivery. In the future, we will continue to focus on "precise response to customer needs" to help global high-end equipment manufacturers achieve dual improvements in performance and efficiency.
