Failure and analysis of CNC special-shaped edging machine

There are many types of CNC special-shaped edging machines, how to choose should be selected according to the characteristics of the processed products and the production scale. Taking the CNC special-shaped edging machine as an example, the CNC special-shaped edging machines that can grind edges include special-shaped machines, linear CNC special-shaped edging machines, die-cutting machines, linear double-sided CNC special-shaped edging machines, etc. How to choose and process according to the processing requirements product. If the product designed to be processed is round, oval or other special-shaped glass, only special-shaped machine or model machine can be selected (because the straight edge edge machine cannot grind round or special-shaped workpieces). If there are many types of products designed and processed and the batch is small, it is more appropriate to choose a special-shaped machine, because the special-shaped machine is more convenient to replace products, and the price of the machine is relatively cheap. If the designed and processed products are small in variety and the batch is relatively large, it is more appropriate to choose a paint touch-up machine , Because the production efficiency of the machine is high, it is easy to ensure the machining accuracy.

If the product designed and processed is rectangular or rectangular glass, only a straight-line fillet machine or a straight-line double fillet machine can be used (because the special-shaped machine and the forming machine generally cannot grind the rounded edge). When the product accuracy requirements are not very high and the production batch is not too large, the general linear round edge machine can be selected (because its price is low); if the product precision requirements are high and the production batch is also large, the straight edge bilateral round edge machine is used. . A side machine is more suitable.

During the operation of CNC edging machine equipment, its internal parts will be affected by force, heat, friction, wear and so on.

This is the main reason for the failure of CNC edger equipment. Therefore, studying the failure mechanism of parts (components) and identifying failure modes are the main tasks of guarantee diagnosis, and also lay an information foundation for fault diagnosis, so as to achieve the purpose of reducing the whole life cycle cost of equipment. And failure analysis is the main component of diagnosis theory.

The general failure is the phenomenon that the exponential control special-shaped edger equipment loses or reduces its specified function. The CNC special-shaped edging machine equipment of the enterprise is equipped to meet the production process requirements or complete the expected functions of the project. The function of CNC special-shaped edging machine equipment reflects its value in production activities and the degree of guarantee for production. The failure of CNC special-shaped edger equipment will seriously affect the quantity and quality of enterprise products, so it is necessary to explore the failure rule; manage and record the failure; analyze the failure mechanism and take effective measures to control the failure.

The purpose of the maintenance technical documents for CNC special-shaped edging machine equipment is

①The basis for preparing materials and spare parts before repairing;

②The basis for formulating working hour quota and cost budget;

③ The basis for formulating the maintenance operation plan;

④Guide maintenance work;

⑤ Acceptance of repair quality standards.

Maintenance technical documents commonly used in CNC special-shaped edger equipment maintenance include: maintenance technical task book, maintenance parts list, material list, maintenance process regulations and maintenance quality standards. For the maintenance of CNC special-shaped edging machine equipment, the content of the above-mentioned various maintenance technical documents can be appropriately combined and simplified according to the complexity and simplicity of the maintenance content.
