Polished Half Round Head Cross Recessed Head Screw

Titanium polished Half round head cross recessed screw agricultural machinery.

Description

Titanium screws are one of the ultra-high-strength screws produced by special materials.

Titanium screws are produced and processed with high-strength heat-resistant and corrosion-resistant titanium alloy materials. 

Polishing refers to the use of mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is the use of polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece.
During polishing, the high-speed rotating polishing wheel (circumferential speed above 20 m/s) is pressed against the workpiece, so that the abrasive can roll and micro-cut the surface of the workpiece, thereby obtaining a bright machined surface. The surface roughness can generally reach Ra0.63 ~0.01 microns; when non-greasy matting polishing agent is used, it can matte the bright surface to improve the appearance. When mass production of bearing steel balls, barrel polishing is often used.

Chemical (or electrochemical) degreasing → hot water washing → flowing water washing → rust removal (10% sulfuric acid) → flowing water washing → chemical polishing → flowing water washing → neutralization → flowing water washing → transfer to the next surface treatment process.

Working environment: The working environment of traditional polishing process is harsh, and sand, iron filings, dust, etc. are generated during the polishing process, which seriously pollutes the environment;Processing efficiency: manual polishing;

Paving material consumption: polishing needs to consume auxiliary materials such as polishing wheels, abrasives, and abrasive belts;
Adaptability: Polishing can process simple profiles such as flat surfaces, but cannot process curved surfaces. If processing complex shapes such as R arcs and curved surfaces.
