CNC Machined Long Axis Threaded Shaft

Processing Technology for Shaft Components

Shaft components are common and critical basic elements in the mechanical manufacturing industry, widely used in various mechanical equipment such as automobiles, machine tools, ships, etc. The machining quality of shaft parts directly affects the performance and service life of the entire mechanical equipment. Therefore, mastering the machining process of shaft parts is of great significance for improving product quality and reducing production costs.

Classification and Characteristics of Shaft Components

Shaft components can be divided into optical axis, stepped shaft, hollow shaft, and crankshaft according to their shape and structural characteristics. These parts need to meet high requirements for dimensional accuracy, shape accuracy, and surface quality during the machining process.

The Machining Process Flow of Shaft Parts

The machining process of shaft parts mainly includes the following steps: blank preparation, rough machining, semi precision machining, precision machining, heat treatment, grinding, and inspection.

Preparation of raw materials

Blank preparation is the first step in the machining of shaft parts, mainly including forging, casting, and welding methods. The quality of raw material preparation directly affects the smooth progress of subsequent processing and the final quality of the parts.

Rough machining

The main purpose of rough machining is to remove the excess on the surface of the blank, so that the shape of the part approaches the final requirement. Common rough machining methods include milling, turning, and planing.

Semi precision machining

Semi precision machining is the process of further adjusting the shape and size of parts based on rough machining, in preparation for subsequent precision machining. Semi precision machining usually uses methods such as milling and turning.

Precision machining

Precision machining is a crucial step in the machining of shaft components, requiring high dimensional accuracy and surface quality. The commonly used precision machining methods include grinding, grinding, and polishing.

Heat treatment

Heat treatment is the process of improving the mechanical properties and wear resistance of parts by altering the internal structure of the material. Common heat treatment methods include annealing, normalizing, quenching, and tempering.

Grinding processing

Grinding processing is mainly used to improve the surface quality of shaft parts to meet their usage requirements. Grinding processing can be divided into outer circle grinding, inner circle grinding, and end face grinding.

Inspection

Inspection is the final step in the machining of shaft parts, mainly checking whether the size, shape, and surface quality of the parts meet the design requirements. The commonly used inspection methods include dimension measurement, geometric tolerance detection, and surface roughness detection.

Precautions During the Machining Process of Shaft Parts

Reasonably select cutting parameters and cutting tools to ensure machining efficiency and quality.

Strictly control the thermal deformation and vibration during the machining process to avoid affecting the machining accuracy of the parts.

Pay attention to the cleanliness and rust prevention of parts to prevent damage from iron filings and oil stains generated during the processing.

Regularly maintain and upkeep the processing equipment to ensure its normal operation and machining accuracy.
