Introduction to Precision CNC Micro Turning Small Stainless Steel Parts

Precision CNC micro turning small stainless steel parts are a kind of high-precision parts specially made for automobile industry. This product is manufactured by JST and processed by CNC turning and cold heading. Its raw materials are rich and varied, including stainless steel, carbon steel and brass, which can meet the performance requirements of different automobile parts.

Features of Precision CNC Micro Turning Small Stainless Steel Parts

Material characteristics

Stainless steel has excellent corrosion resistance, which can effectively resist the corrosion of various chemicals and humid environment during automobile operation; Carbon steel, on the other hand, has high strength and hardness, which is suitable for parts with high requirements on mechanical properties; Brass plays a role in some special automobile electronic components because of its good conductivity and processability.

Exquisite processing technology

Through CNC turning and cold heading technology, the dimensional accuracy of the parts is extremely high, and the tolerance range is controlled between ±0.02mm and ±0.10mm, which ensures the accurate installation and stable operation of the products in the complex mechanical system of automobiles.

Excellent surface treatment

The salt spray test of galvanized parts can reach 48 hours, and nickel plating can further improve the wear resistance and corrosion resistance of the parts, so that the parts can still maintain good performance in the harsh automobile use environment.

Advantages of Precision CNC Micro Turning Small Stainless Steel Parts

Rich production experience

Since 2010, JST has become a supplier of many large companies, accumulated rich production experience, deeply understood the high standards and strict requirements of the automobile industry, and accurately grasped the product quality.

Strict quality control

Each batch of orders can provide inspection reports and test reports. From the procurement of raw materials to the delivery of finished products, it goes through many strict quality inspection procedures to ensure the stable and reliable product quality.

Large-scale production capacity

The order processing capacity of 500,000 pieces per month and the low minimum order quantity of 50,000 pieces fully demonstrate the powerful large-scale production capacity and can meet the large demand for parts in the automobile industry.

Application

Mainly used in various fields of automobile manufacturing:

Engine system

In the fuel injection system, valve assembly and other parts of the engine, these parts rely on high precision and good mechanical properties to ensure the efficient operation and power output of the engine.

Brake system

Used for key components such as brake calipers and brake discs. Its high strength and corrosion resistance ensure the safety and reliability of the brake system under frequent use.

Electrical system

Among the electrical connection parts of automobiles, the parts made of brass use its good conductivity to ensure the stable transmission of current and ensure the normal work of automotive electronic equipment.


1. Why is the minimum order quantity 50,000 pieces of each kind?

This is determined by comprehensive consideration of production cost, production efficiency and equipment debugging. The equipment debugging cost of CNC turning and cold heading process is high, and these costs can be effectively shared by mass production. At the same time, a large order quantity is also helpful to optimize raw material procurement, production process management and other links to ensure the cost performance and quality stability of products.


2. What is the difference between nickel plating and zinc plating, and how to choose it?

Nickel coating has high hardness, good wear resistance and brighter and more beautiful appearance, which is suitable for parts with high requirements on surface hardness and aesthetics. Galvanizing has good corrosion resistance and relatively low cost, especially in the salt spray test. For example, exposed parts or cost-sensitive parts of automobiles are more suitable for galvanizing. The selection should be based on the use environment, performance requirements and cost budget of the parts.


3. The tolerance range is ±0.02mm to ±0.10mm, can it meet the accuracy requirements of all automobile parts?

This tolerance range can meet the accuracy requirements of most automobile parts. However, some high-end or special parts in the automobile industry may have stricter accuracy standards. In view of this situation, JST can further improve the precision of parts and meet the special requirements by optimizing the process and strengthening quality control according to the special needs of customers.


4. What does 48 hours of salt spray test mean?

Salt spray test for 48 hours is an important index to measure the corrosion resistance of galvanized parts. This means that in the simulated salt spray environment, the parts can resist corrosion for 48 hours without obvious corrosion. This performance ensures that the parts can still be kept in good working condition under the harsh environment of wet and salty automobile, such as coastal areas or road environment where salt is sprinkled and snow is removed in winter, and the service life of the parts is prolonged.


5. How to ensure the stability of product quality?

JST has established a perfect quality management system, with strict standards and procedures, from the strict screening of raw materials to the precise control of each process in the production process, and then to the multi-round inspection of finished products. At the same time, through the long-term cooperation and accumulated experience with many large automobile enterprises, the production technology and quality control methods are continuously optimized to ensure the stable and reliable quality of each batch of products.


An automobile parts manufacturer: "Since we cooperated with JST, the precision CNC micro turning small stainless steel parts they provided for us have never let us down. The product quality is stable, the dimensional accuracy fully meets our requirements, and it has excellent performance in the timeliness of supply. It has never affected our production progress because of the supply of parts. "


Automobile engine manufacturer: "JST's parts are excellent in our engine products. Especially their precision CNC micro turning small stainless steel parts, after a long period of use and the test of various bad working conditions, still maintain good performance. The nickel-plated surface is not only beautiful, but also has good wear resistance, which effectively prolongs the service life of engine parts. "


Automotive Brake System Supplier: "JST's products have helped us improve the overall quality of the brake system. The excellent performance of galvanized carbon steel parts in salt spray test makes us full of confidence in the reliability of products in complex environment. Their inspection reports and test reports also make us more assured in quality control and are trustworthy partners. "
