Products Description
Deburring can remove loose burrs, unwanted edges and scratches on metal parts and tools. If left untreated, it can cause injury or damage to the machine and operator.
Surface treatment and polishing of glass beads is a very effective method that can mix surface defects, improve sealing and improve the appearance (matt or textured) of all kinds of molds, thermoforming molds and other complex molds, while improving the corrosion resistance and lubrication of moving parts.
In situations where there is a high notch sensitivity due to elastic requirements, such as springs, crankshafts, gears, etc., the use of glass beads for shot blasting is particularly effective. By using fine glass beads for wet sand blasting, cracks and fractures in the metal can also be exposed as fine black lines, otherwise they will be overlooked.
Core Features ：
1. Structure and hardness: Grinding glass beads are mostly spherical or nearly spherical, with a Mohs hardness of 5-7, between metal and non-metal, suitable as grinding media.
Chemical stability: Made of sodium calcium glass or borosilicate, resistant to acid and alkali corrosion, and will not undergo chemical reactions with processed materials.
2. Application scope: Mainly used for metal surface treatment (such as sandblasting, deburring), optical device polishing, semiconductor component cleaning and other fields.
Main functions：
1. Improve efficiency: The spherical structure can tightly fill the grinding gap, refine material particles through rolling action, and reduce grinding time.
2. Uniform treatment: Uniform particle size ensures even pressure dispersion and avoids cracks or deformations caused by local stress concentration.
3. Surface optimization: After grinding, the material surface becomes smoother and the adhesion is enhanced, making it suitable for painting, adhesive bonding, and other scenarios.
