Machining Process of Custom CNC Turned Components：
Design and Programming:
According to the design requirements of the parts, use CAD software to create a 3D model of the parts.
Using CAM software to convert 3D models into turning programs, determine tool paths, cutting parameters (such as cutting speed, feed rate, cutting depth, etc.), and machining sequences.
Prepare raw materials:
Choose suitable bar or blank materials that meet the requirements of the parts in terms of size and material.
Conduct a preliminary inspection of the raw materials to ensure they are defect free.
Install fixtures and blanks:
Install the specialized fixture on the chuck of the CNC lathe and ensure the accuracy and stability of the fixture.
Fix the blank onto the fixture, ensuring that it is securely installed and concentric with the lathe axis.
Tool selection and installation:
According to the processing requirements, choose suitable turning tools, such as outer circle turning tools, inner hole turning tools, cutting tools, etc.
Install the tool correctly on the tool holder and perform tool alignment to determine the starting position and coordinate system of the tool.
Rough:
Rough turning is one of the main stages of turning machining. It uses a larger cutting depth and faster tool speed for preliminary processing, with the aim of quickly removing most of the rough material on the surface of CNC Turned Components. Rough cutting typically focuses on rapid material removal rather than achieving final dimensional accuracy or surface quality.
Semi polishing:
After rough turning, a semi precision turning stage is usually carried out. In this stage, the cutting depth is reduced and the tool speed is increased, with the aim of achieving the predetermined size and high smoothness of the CNC Turned Components surface. Semi precision turning is a transitional stage between rough turning and precision turning, which further reduces material removal and prepares for the subsequent precision turning.
Completing:
Precision turning is the last critical process in turning machining. At this stage, further reduce the cutting depth and tool speed to improve the dimensional accuracy and flatness of the workpiece. The main goal of precision machining is to ensure that CNC Turned Components meet the predetermined dimensional accuracy and surface smoothness requirements.
Superfinishing (optional):
For certain applications that require extremely high surface finish, the polishing stage may also be carried out. The light car adopts very small cutting depth and very slow tool speed to further improve the surface smoothness of CNC Turned Components.
Inspection and repair:
After each turning process, it is usually necessary to inspect the workpiece to ensure that the machining quality meets the technical requirements. The inspection content includes size, shape, surface smoothness, etc. If excessive defects are found, they need to be repaired to meet technical requirements.
