Today, as high-end equipment manufacturing continues to move towards high precision and performance, fasteners, as the most fundamental and critical connecting components, have a direct impact on the safety and stability of the entire machine's operation due to their processing quality. As a technology-based enterprise specializing in the manufacturing of high-end standard parts, Zhejiang Jingkong Standard Parts Co., Ltd. deeply understands that the quality of every fastener cannot be separated from the support of the core process of "turning machining".

1、 Basic principles and functions of turning machining

Turning is a basic mechanical machining method that uses the relative motion between a rotating workpiece and a fixed tool to cut metal materials. It is widely used in the external processing, thread forming, and dimensional finishing of fasteners such as bolts, nuts, and bolts, and is an indispensable process foundation in the manufacturing of standard parts.

The advantages of turning technology lie in high machining accuracy, strong adaptability, and batch automation production, especially suitable for metal parts with symmetrical structures and strict dimensional accuracy requirements. For high-strength and high-performance materials such as B7, F53, HC276, etc., turning can effectively achieve surface processing and dimensional control, ensuring that the parts still have good mechanical properties and assembly matching under extreme working conditions.

2、 Precision controlled turning machining capability

As a manufacturing enterprise with strong technical accumulation in the industry, Zhejiang Jingkong has built a turning platform covering high-precision CNC lathes, automatic feeding systems, and composite machining units, comprehensively improving the automation level and consistency control capability of fastener processing.

1. Leading equipment configuration

The company adopts industry-leading standard part dedicated CNC lathes to achieve high-speed and stable processing efficiency, and is equipped with automatic tool compensation and error correction systems to ensure that various bolts and nuts still have excellent dimensional stability under high-strength working conditions.

2. Systematize the processing flow

From raw material cutting and initial processing to precision turning and thread forming, Zhejiang Precision Control strictly implements process parameter management and inspection rhythm in the turning process to ensure controllable accuracy and process stability of each step.

3. Strong material adaptability

Faced with diverse high-performance materials, the company continuously optimizes turning parameters and tool configurations, effectively solving technical difficulties such as tool wear and chip control in the processing of high hardness and high corrosive materials, and improving turning efficiency and surface quality.

3、 Quality control runs through the entire process

Zhejiang Jingkong has established a comprehensive physical and chemical performance testing center and online detection mechanism, supplemented by dimensional measurement, thread gauge inspection, spectral analysis and other means during the turning process, to achieve real-time identification and feedback correction of quality problems, truly implementing "precision manufacturing" into every standard part.

In addition, the company has passed the ISO 9001 quality management system certification, and its products strictly comply with domestic and foreign standards such as GB, ANSI, DIN, JIS, etc., ensuring that the turning parts meet the high standard requirements of different industries in terms of accuracy, strength, compatibility, etc.

4、 The core force driving manufacturing upgrading

Faced with the trend of manufacturing industry transforming towards "high-end, intelligent, and green", turning machining is also continuously evolving towards digital control, tool optimization, data closed-loop, energy conservation and consumption reduction. Zhejiang Jingkong will continue to increase investment in technology research and development, continuously optimize the turning process chain, and promote the transition of standard part manufacturing from "precision manufacturing" to "intelligent manufacturing".
