A Comprehensive Guide to CNC Lathe Processing

NC lathe processing is a highly automated precision manufacturing technology suitable for the processing of a variety of complex parts. Through computer-controlled precision operations, not only improve processing accuracy but also reduces manual operation time and ensure the consistency of product quality. This technology is widely used in aerospace, automobile manufacturing, electronics, and other fields, and is an indispensable and important tool in modern manufacturing.

Processing process of CNC lathe

The processing process of CNC lathes is mainly divided into four stages: preparation, tool preset, processing, and quality inspection. Each stage is crucial to ensure the high precision and quality of the final product.

Preparation:

· Familiar with part drawings and process documents, and clarify processing requirements and processes.

· Develop a process plan, and determine processing parameters and cutting tools.

· Check the status of CNC lathe equipment and tools to ensure normal operation.

· Install fixtures and tools to ensure safety during installation.

Tool preset:

· Set X, Y, and Z axis coordinates, as well as processing depth and width.

· Preset feed rate, speed, and coolant use.

· When switching tools, reset parameters such as tool height and tool tip radius.

Processing process:

· You can choose automatic or manual processing, and manual processing requires operator operation.

· During automatic processing, the program is pre-arranged and the machine tool will automatically perform the processing task.

·During the processing, it is necessary to continuously observe the processing status, especially the wear of the tool, and adjust the parameters in time.

Quality inspection:

·After the processing is completed, a quality inspection is carried out to ensure the quality and accuracy of the parts.

·Check the quality and dimensional error of the processed surface.

·Measure the aperture and depth error.

·Check the shape and position tolerance of the parts.

CNC lathe processing range

CNC lathe processing is suitable for a variety of materials, including stainless steel, carbon steel, titanium alloy, plastic, etc., and can process square, round, and complex combined structure parts. These functions show the diversity and complexity of CNC lathe processing. CNC lathes can not only perform basic turning processing but also expand to various processing methods such as boring, drilling, tapping, and face milling. This enables CNC lathes to produce a variety of parts, such as shaft parts, gears, disc parts, etc. In addition, CNC lathes can also process complex surfaces, which are suitable for parts such as ball screws and spark plugs.

In terms of machining accuracy, CNC lathes can process high-precision rotating parts, with geometric profile accuracy up to 0.0001mm and surface roughness Ra up to 0.02μm. CNC lathes can also easily process special threads.

Characteristics of CNC lathe machining

1. High degree of automation: The machining process of CNC lathes is highly automated. Operators only need to set up programs and monitor the machining process, which greatly reduces the intensity of physical labor, but also increases the requirements for mental labor.

2. High precision and stability: CNC lathes have high positioning accuracy and repeated positioning accuracy, which can ensure the consistency of the size of a batch of parts and ensure the machining quality.

3. High production efficiency: CNC lathes can complete multiple machining surfaces in one clamping, reducing auxiliary time and significantly improving overall production efficiency.

4. Promote new product development: CNC lathe machining does not require complex process equipment. It only needs to compile machining programs to realize the machining of complex parts, which is conducive to the rapid development and design modification of new products.

5. Foundation of an advanced manufacturing system: CNC lathe and its processing technology are the core of computer-aided manufacturing and have the potential for further development.

6. High maintenance requirements: Due to the complex technology of CNC lathe, maintenance personnel are required to understand both mechanics and microelectronics and have high maintenance skills.
