Persistently Adhere to Stringent Quality Control

CNC machining typically provides a high surface quality with a smooth, fine surface texture. However, the surface quality of 3D printing is usually rough, and subsequent processing is required to achieve a better surface finish. However, with the development of 3D printing technology, some advanced 3D printing methods are also able to provide higher quality surfaces, but usually require additional processing steps.

Both CNC machining and 3D printing require quality control to ensure products meet specifications. In CNC machining, common quality control methods include dimensional inspection using precision measuring tools, surface quality assessment, and functional testing. For 3D printing, quality control includes checking printing parameters, material quality, and print quality, as well as conducting post-processing and testing.

Equipment Maintenance and Calibration: Regular maintenance and calibration of machine tool equipment is fundamental to ensuring high-quality manufacturing. Maintain the accuracy and performance of equipment, including regular inspection and replacement of tools, checking the accuracy of sensors and measuring instruments, etc.

Appropriate process planning: formulate appropriate process planning, including reasonable cutting parameters, tool selection and machining path planning. Ensuring that each process is carefully planned and optimized to achieve the required precision and surface quality requirements.

Quality Control Measures: Establish strict quality control measures, including the use of advanced measuring instruments for dimensional inspection and surface quality assessment. Carry out process monitoring and statistical process control to discover and correct potential quality problems in time.

Material selection and inspection: Select high-quality raw materials that meet the requirements, and conduct incoming inspection to ensure their quality meets the specifications. Proper material selection is critical to the quality and performance of the final product.

Training and skills: Provide necessary training and skill improvement for operators to ensure that they have the correct processing knowledge and technical capabilities, and can accurately operate machine tools and implement process requirements.

Continuous improvement: regularly evaluate and analyze the production process, look for opportunities for improvement, and take appropriate measures to improve production efficiency and product quality. Drive continuous improvement with advanced technologies and tools, such as data analytics and automated systems.
