Preparation requirements for machine tool coating construction process

The process department is responsible for the preparation of coating process, which is to select appropriate process technology and management methods according to the design requirements and production scale of products, organize materials, equipment, tooling, operation procedures, testing technology, labor and production facilities, form a complete set of process documents for guiding operation and control, and ensure the stable coating quality of products All activities in accordance with design specifications and internal control standards 1 Define the design requirements of machine tool coating 2 Investigate the coating design scheme, understand the coating process level of similar products at home and abroad, the use of new processes and materials, whether the special requirements of customers are reasonable and what measures are taken to achieve the requirements of customers 3 Coating process test: carry out necessary process test on the new materials and processes to be used to master their quality assurance performance, construction performance and repair performance 4 The design of coating process documents plays an important role in ensuring the coating quality of products, reducing material consumption and improving economic benefits (1) the design process documents shall be based on relevant national, industrial and enterprise standards, relevant standardization data, customer's special requirements and design requirements in the contract (2) types of process documents: process card for pretreatment of casting painting, process card for pretreatment of sheet metal painting, process card for painting of parts and components, process card for painting of commodity machine tools (3) the contents of the coating process card include the operation procedures, materials used, construction conditions, construction viscosity, equipment used, tools used, working position instruments used, construction methods, film thickness, drying methods, drying time, quality requirements of the film, inspection methods and other technical requirements (4) the design of process equipment and working position apparatus is to ensure the coating quality and facilitate the coating construction The painted parts shall not be scratched and bruised and the coating construction wage shall be increased 5 Create suitable coating environment conditions According to the requirements of process design, necessary control measures shall be taken for the temperature, humidity, lighting, air quality, noise, etc of the coating construction environment 6 The distribution of the coating process documents shall be distributed to the coating workshop, the quality inspection department, the labor and personnel department and the production management department 7 There is a set of strict management system and modification procedure for the modification of process documents (1) reasons for process modification: ① due to the modification of design drawings or technical requirements, process documents shall be modified accordingly ② the unreasonable design of process documents cannot meet the design requirements or guarantee the coating quality requirements ③ implement new standards: use new materials and equipment; correct the found wrong process (2) the modified process documents must be correct, complete, unified and clear (3) after the new process is issued, the original process must be recovered and "void" shall be cancelled (4) do a good job in the aftertreatment Do a good job in the treatment of the stock painted parts executed according to the original process
