How to Repair the Casting Defection

The most fundamental focus of the solution to repair the casting defection in castings is "heat balance." The method is: (1) In the thick and hot joints formed by the machine tool casting structure, rapid solidification is carried out, artificially causing the basic balance of the temperature field throughout the casting of the machine tool. [...]

Inspection of Internal Defects in Castings

For internal defects, commonly used non-destructive testing methods are radiation detection and ultrasonic testing. Among them, the radiation detection effect is the best, it can obtain an intuitive image reflecting the type, shape, size and distribution of internal defects, but for large castings with large thickness, ultrasonic testing is very effective, and the position of [...]

Detection of Casting Surface

Detection of casting surface: 1) Liquid penetration test Liquid penetrant testing is used to inspect various opening defects on the surface of castings, such as surface cracks, surface pinholes, and other defects that are hard to find by the naked eye. The commonly used penetration test is coloring detection, which wets or sprays a colored [...]

Defects of Sand Casting

Defects of Sand casting include: cold isolation,insufficient pouring, blowhole, sand bonding, sand inclusion, sand hole, sand swelling, etc. 1) Cold insulation and insufficient pouring The liquid metal filling capacity is insufficient, and the molten metal stops flowing before the cavity is filled, which will cause the casting to have insufficient or cold insulation defects. When [...]

Casting Quality

Casting quality mainly includes appearance quality, intrinsic quality and using quality. Appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation and weight deviation of the casting; the intrinsic quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure of the casting, and the holes, cracks, inclusions existing in [...]

Application of Gearbox

The gearbox acts as a matching precision and transmission torque between the prime mover and the working machine or the actuator. The gearbox is a relatively precise machine that is used to reduce the speed. According to the different drive stages, it can be divided into single or multi-stage reducers. According to the shape, it [...]
