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.
When we embark on creating custom CNC turned components, our machining process is a well – orchestrated sequence of steps designed to deliver parts that meet the highest standards of precision and quality. Each stage plays a crucial role in transforming raw materials into components that are tailored to our clients’ specific needs.
Our journey starts with in – depth communication and understanding. We engage closely with clients to fully grasp their requirements, whether it’s for a small – batch prototype or large – scale production. We analyze the intended application of the components, taking into account factors like load – bearing capacity, environmental conditions, and compatibility with other parts. This initial consultation allows us to determine the most suitable materials and design approach, setting the foundation for the entire machining process.
Once the specifications are clear, we move on to the design phase. Using advanced computer – aided design (CAD) software, our team of experienced designers creates detailed 3D models of the custom components. We pay meticulous attention to every dimension, curve, and feature, ensuring that the design not only meets the functional requirements but is also optimized for CNC turning. This involves considering factors such as tool accessibility, ease of machining, and potential areas for material removal. After the design is finalized, we use computer – aided manufacturing (CAM) software to generate the machining program, carefully programming the toolpaths, cutting speeds, and feed rates to achieve the desired results.
With the design and program in place, we source the raw materials. We have established relationships with reliable suppliers to ensure that we obtain high – quality materials that meet our strict standards. Whether it’s metal alloys like aluminum, stainless steel, or titanium, or engineering plastics, we thoroughly inspect the materials upon arrival at our facility. We check for any defects, inconsistencies in composition, or dimensional variations that could affect the machining process or the final quality of the components.
The actual CNC turning process is where our state – of – the – art machines shine. We mount the raw material onto the lathe, securing it firmly to prevent any movement during machining. Our CNC turning machines are equipped with advanced multi – axis capabilities and high – precision spindles, enabling us to perform a variety of operations with great accuracy. We start with rough turning, where we quickly remove the majority of the excess material to bring the part close to its final shape. This is followed by finish turning, where we use finer cutting tools and more precise settings to achieve the exact dimensions and surface finish required. Throughout the turning process, we continuously monitor the operation, checking for any signs of tool wear or issues that could impact the accuracy of the component.
Quality control is an integral part of our machining process. We conduct in – process inspections at regular intervals, using precision measuring tools such as calipers, micrometers, and height gauges to check the dimensions of the components. We also use advanced non – contact measurement techniques, like optical comparators, to verify the shape and profile accuracy. If any deviations from the specifications are detected, we immediately make the necessary adjustments to the machining parameters or replace the cutting tools. After the components are fully machined, they undergo a final, comprehensive inspection. We use coordinate measuring machines (CMMs) to measure the parts with extremely high precision, ensuring that they meet all the required tolerances.
In some cases, additional operations may be required after the initial CNC turning. This could include processes such as drilling, tapping, threading, or milling to add specific features or holes to the components. We also offer various surface treatment options, like polishing, plating, or anodizing, to enhance the appearance, durability, and functionality of the parts.
Finally, we package the custom CNC turned components carefully to protect them during transportation. We label each component clearly with relevant information, such as part number, batch number, and client details. Our goal is to deliver components that not only meet but exceed our clients’ expectations, and our comprehensive machining process is designed to ensure just that.
