1. Mechanical grinding: Titanium has high chemical reactivity, low thermal conductivity, high viscosity, low mechanical grinding and grinding ratio, and is easy to react with abrasives. Ordinary abrasives are not suitable for titanium grinding and polishing. Hard abrasives, such as diamond, cubic boron nitride, etc., the polishing linear speed is generally 900 ~ …

Grinding is an abrasive machining process that uses a grinding wheel as the cutting tool. The process is divided into two basic applications: Precision grinding. Rough grinding and cutting off. Precision grinding (more commonly, die grinding) with handheld tools is done to remove material from small areas or spots, cavities, or other confined ...

These interactions feed into three major commercial grinding processes: rough grinding, precision grinding and ultra-precision grinding. Rough grinding maximizes the metal removed at the cost of surface finish. It primarily sees use in cutting off billets, grinding weld beads smooth and snagging gates and risers from castings.

It is widely used in snagging wheels (for grinding irregularities from rough castings), which operate at 9,500 SFPM. It is also used in cutoff wheels. Rubber: In rubber-bonded wheels, pure rubber is mixed with sulfur. It is extremely flexible at operating speeds and permits the manufacture of grinding wheels as thin as 0.006 inch for slitting nibs.
