Some basic common sense and knowledge of machining!
TR90 is a thermoplastic material that is incredibly durable, flexible, and lightweight. Frames made with TR90 are extremely comfortable. Since they are flexible, they can bend under pressure and contour your customer's face comfortably. Because of the TR90 frame's flexibility, it also makes them resilient to damage.

1. Commonly used equipment for machining:
Including digital milling machines, digital forming grinding machines, digital display lathes, EDM machines, universal grinding machines, cylindrical grinding machines, internal grinding machines, precision lathes and other equipment, these equipment can be used for precision parts of the car, milling, planing, grinding and other processing Its processing accuracy can reach 2um.
2. Machining process:
The production process of machining includes the transportation and storage of raw materials, production preparation, blank manufacturing, processing and heat treatment of parts, assembly and debugging of products. Through machining, the shape, size and performance of the raw materials can be changed to make them into a finished product. This process, also called the process, consists of one or several sequential processes.
3. Processing type of machining:
Single-piece machining: a part is produced separately, and repeated production is rare. Batch processing: It is the production of the same parts in batches. Mass processing: When the amount of product produced is large, it is necessary to repeat the production of one part frequently. The process of the part is scheduled. Due to the different types of parts, the processing methods, equipment, tools, blanks and technical requirements are different.
4. Precautions for mechanical processing: (1) To facilitate the processing operation, minimize unnecessary bending and squatting. (2) Positioning should be accurate and reliable to prevent vibration and cause errors . (3) The moving direction of the equipment operating parts and the moving direction of the operated parts must meet the specified requirements and should be easily marked. (4) Set the necessary interlocking mechanism to prevent uncoordinated action during operation and cause danger. (5) The structure of the handle, handwheel, and button should be in accordance with the requirements. The general start button should be installed in the casing and equipped with a guard ring to prevent accidental touch. The shaft should be equipped with an automatic release device to prevent the hand wheel and the handle from injuring people.
