The machining of fasteners is a crucial aspect in the manufacturing industry. Fasteners, such as bolts, nuts, screws, etc., play a crucial role in mechanical connections. Its machining has the following characteristics:
Material diversity
Common materials include carbon steel, alloy steel, stainless steel, etc. Different materials have different mechanical properties and processing characteristics, which need to be selected according to specific usage environments and requirements.
High precision requirements
The dimensional accuracy and thread accuracy directly affect the connection reliability and stability of fasteners. For example, the diameter, pitch, thread tolerance, etc. of bolts need to be strictly controlled.
volume production
Due to its widespread application in various devices and structures, large-scale production is usually required to meet market demand.
Multiple processes
Generally, it includes processes such as turning, milling, tapping, and rolling.
Turning is used for machining cylindrical parts, milling can be used for machining flat or special shapes of the head, and tapping and rolling are used to form threads.
In automotive manufacturing, a large number of fasteners require strict machining and quality testing to ensure the safety and reliability of the vehicle. In the construction industry, high-strength fasteners also require high-precision machining to withstand huge loads. The machining of fasteners requires comprehensive consideration of multiple factors such as material, precision, process, cutting tools, and quality inspection to produce high-quality and compliant products.
CNC machining also known as Computerized Numerical Control Machining, is a technology that utilizes CNC machine tools to perform precise machining on workpieces. CNC machine tools are controlled by computers and automatically complete machining operations such as cutting, drilling, and milling by reading pre written programs (usually G code).
The main characteristics of CNC machining technology include:
High precision: CNC machining can achieve high-precision machining through computer control, meeting the machining needs of various complex parts.
High degree of automation: CNC machining can automatically complete the machining process, reduce manual operations, improve production efficiency and machining quality.
Good flexibility: CNC machining can process workpieces of various materials and shapes, with strong adaptability.
CNC machining technology is widely used in various fields, such as aerospace, automotive manufacturing, mold manufacturing, electronic equipment manufacturing, etc. For example, in the aerospace field, CNC machining technology is used to manufacture high-precision components such as aircraft engine blades and rocket engine nozzles; In the field of mold manufacturing, CNC machining technology can improve the manufacturing efficiency and quality of molds, and reduce production costs.
In addition, CNC machining technology also includes various machining methods, such as CNC milling, CNC turning, CNC EDM wire cutting, etc., and suitable machining methods can be selected according to different machining needs.
