Sheet machine and mechanical accuracy

Quality index of the modern mechanical and electrical products including the function, performance, working accuracy, durability, reliability, efficiency, life, etc. Mechanical precision is one of the most important indicators to measure performance of mechanical and electronic products, is also a main technical parameter to evaluate the quality of the mechanical and electrical products. And in whatever the mechanical equipment in the machinery are to have mechanical precision, this kind of plastic machinery, such as sheet machine will need to have a sheet production, the precision of extrusion related assembly configuration. The precision of geometric parameters of mechanical parts ( Hereinafter referred to as geometric accuracy) Is the decisive factor affecting the quality of mechanical and electronic products. Quality index of the modern mechanical and electrical products is closely related to the product of geometry accuracy, did not have enough quantity of geometric accuracy, mechanical products is losing its use value, lunch box machine is one of them has the geometry precision mechanical equipment, it produces snack box has the geometry definition, so the appearance of mold size needs to be well designed. Geometric accuracy refers to the amount of parts after processing the actual value of geometric parameters and design requirements to coincide with the theoretical value of the degree, the degree of deviation between them is called machining error. Machining precision in the numerical usually use to reflect the size of the machining error and measurement. Geometric quantity usually include mechanical parts precision geometric size accuracy and geometric accuracy, orientation precision, position precision and surface roughness. When the geometric form a certain parts, if the error is smaller, the precision is higher; If the error is bigger, the accuracy is lower. For mechanical parts and mechanical and electrical products the machine also has a geometric accuracy requirement. When need to be assembled with requirements.
